What this does: the Rust SDK can now send and find DashPay private contact requests.
To send, it appends a sealed entry to a private document type's store, paid from the shielded pool (transition type 29).
To find, it reads a page of that store and sorts its entries with a wallet's keys into three groups:
entries addressed to one of the wallet's identities;
entries the wallet sent, recovered after a restore from seed;
entries that open but are refused.
On top of that sit DashPay helpers: a typed PrivateContactRequest, sealing one, and a reader that checks each request against its sender's and recipient's keys.
A private request is signed by one of the sender's signing keys, as a public request's transition is, with the same identity signer. The signature sits inside the encrypted entry: only the recipient sees it.
Value: this is the client half of anonymous DashPay contact requests (protocol version 15). Until now the chain could store private entries (#5799, #5804) and the envelope could seal and open them (#5806), but nothing in the SDK sent the transition or walked the store. Wallets, wasm-sdk and the mobile SDKs build on these calls.
Risks: low. It is client code apart from one protocol 15 limit: a private document store's chunk target doubles from 512 KiB to 1 MiB, so DashPay's pages hold 1024 requests instead of 512. Protocol 15 is unreleased, so no store exists under the old number. It also changes the envelope's signature mode in platform-encryption (#5806). Nothing uses that mode yet and nothing is deployed, so the change breaks nothing.
Issue being fixed or feature implemented
Part of anonymous DashPay contact requests for 5.1. Sam's decisions, all applied here:
the outgoing viewing key is derived from the sender identity's DashPay encryption key, H("Dash/PrivDoc/v1/ovk" || encryption secret key), with no new derivation path;
the request is signed by the sender's signing key, rather than carrying a deniable MAC. So the recipient's own key cannot produce a request from someone else, just as it cannot produce a public one. The trade-off: the recipient could prove to a third party who wrote it. Nobody else can see the signature;
a recipient keeps the first request per sender and account reference (there is no chain uniqueness);
PrivateDocumentCreateFromShieldedPool is a trait on Sdk. It builds the type 29 transition from a proven bundle with try_from_bundle, structure-checks it, then broadcasts it and waits for the proof that its nullifiers were spent. It mirrors IdentityTopUpFromShieldedPool. The bundle comes from the dpp builder, as for the other shielded spends.
sdk.private_document_create_from_shielded_pool(dashpay_id, "privateContactRequest",
vec![entry], fee, bundle, None)
before: no SDK call; a wallet had to assemble and broadcast type 29 by hand
after: Ok(StateTransitionProofResult::VerifiedShieldedNullifiers(..))
with no entries, or two the same: refused before broadcasting, as consensus would refuse it
Scanning (platform::private_document_scan)
PrivateDocumentScanKeys prepares a wallet's keys once:
with_recipient(identity, &[(key_id, secret_key)]) adds an identity's keys that entries may be sealed to;
with_sender(identity, key_id, outgoing_viewing_key) adds the key an identity seals its own entries with, and the id of the key it is derived from.
scan_page(target, start, page) sorts a page into received, sent and rejected entries, and returns the position to scan from next:
an entry opened under a key but naming another identity is a replay, and is rejected only if no other identity of the wallet opens it;
an entry refused on both sides is listed once.
verify_sender checks a deniable MAC with the key that opened the entry, trying each key set the identity was added with.
Sdk::scan_private_document_page fetches the proved page and sorts it.
page of 5 entries from position 10, wallet holds Alice (keys 2, 3, outgoing key of key 1) and Bob (key 1)
10: to Alice's key 3 -> received (Alice, key 3)
11: to someone else -> passed over
12: Alice to Dave -> sent (Alice, key 1)
13: Bob's key, names Dave -> rejected: WrongRecipient
14: Alice to Bob -> received (Bob, key 1) and sent (Alice, key 1)
next_position: 15
to_properties and from_properties check the schema's bounds. The SDK's dpp features have no JSON schema validation. A test pins the bounds to the ones dpp parses from DashPay v3.
Sending is three steps, so the signature can come from an identity signer:
private_contact_request_signing_data(contract, sender, encryption_key_id, recipient, recipient_key_id, request) is what the sender signs;
private_contact_request_signature(signer, signing_key, &data) signs it with any Signer<IdentityPublicKey>;
seal_private_contact_request(contract, sender, recipient, recipient_key_id, request, esk_seed) builds the entry. sender names the encryption key and its secret key (for the outgoing viewing key), and the signing key and its signature.
The seal checks every key:
the named key must be the sender's enabled ECDSA_SECP256K1ENCRYPTION key, and its secret must match. The pair's shared key is derived from it;
the signing key must be an enabled AUTHENTICATION key at a level the type's documents are signed at (CRITICAL or HIGH, from the type's requirement, as Drive computes it), ECDSA_SECP256K1 or ECDSA_HASH160, and bound to no other contract or document type (DashPay, or its privateContactRequest type; a contract group bound signs none, as a client cannot read the group's members as they were). The signature must be its own. private_contact_request_signing_keys(contract, identity) lists the keys that qualify;
the recipient key must be an enabled ECDSA_SECP256K1DECRYPTION or ENCRYPTION key, the same rule as public requests.
Sdk::seal_private_contact_request does all three with the bundled DashPay contract, the first signing key the signer holds, and a fresh seed.
private_contact_requests_from_scan(contract, scan, identities, platform_version) reads a scan. identities holds the identities private_contact_request_identities(&scan) lists. Each entry is checked before its payload is decoded:
it must be signed, and its sender must exist;
the encryption key it names must be the sender's, enabled when the entry was appended;
a key of the sender that may sign the type's documents, enabled then, must have signed it. The key is recovered from the signature;
a received entry's recipient key must have been enabled then too;
a sent entry must name the identity and key its outgoing viewing key comes from.
The first request per recipient, sender and account reference is kept.
Sdk::scan_private_contact_requests fetches the page and each listed identity once, then reads it.
received entry naming sender S and encryption key 1
S does not exist -> rejected: SenderNotFound
carries a deniable MAC -> rejected: NotSigned
S's key 1 is not an enabled ENCRYPTION key then -> rejected: SenderKeyNotUsable
signed by S's HIGH signing key, enabled then -> received
signed by S's key disabled before the entry, or at MEDIUM or MASTER -> rejected: SenderKeyNotUsable
signed by a key S does not hold (the recipient's, say) -> rejected: SenderNotAuthenticated
the recipient key was disabled before the entry -> rejected: RecipientKeyNotUsable
no sender (anonymous) -> rejected: AnonymousSender
second request from S, same accountReference -> rejected: Duplicate (the first is kept)
sent entry recovered with S's outgoing viewing key of key 1
names key 3, or another identity, or no key of S signed it -> rejected: SenderNotAuthenticated
platform-encryption (envelope signature mode)
A signature now signs the double SHA-256 of the signing data m. That is how a Dash identity signer signs data, so a wallet signs with the signer it signs transitions with. m is a 32-byte hash, which no transition's signable bytes can be.
PrivateDocumentSender::Signature takes the signature instead of a secret key. The seal refuses bytes that are not a signature. New functions:
private_document_signing_data
sign_private_document_signing_data
recover_private_document_signer
OpenedPrivateDocumentEntry::recover_signer
The key id an entry names may be another key than the signer: DashPay names the encryption key, and the signer is recovered.
The authenticated data m now names the recipient key ser(R), in every mode, so a body re-encrypted to another key of the same identity authenticates no sender. private_document_signing_data takes the recipient. The MAC and signature vectors are re-pinned.
PrivateDocumentRecipientKeys wipes its secret keys on drop. PrivateDocumentEnvelopeError is now Clone, with a new NotSigned.
signature mode, signing data m
before: auth = ECDSA(m) by the named key, signed with a secret key handed to the seal
after: auth = ECDSA(SHA-256(SHA-256(m))), the signature Signer::sign(key, m) returns;
the signer is recovered from it
Changes from review
Validation in DPP. Requests are checked against their type's schema with dpp's DataContract::validate_document_properties, before encoding when sealing and after decoding when reading, as the payload codec asks. The SDK's own bound checks are gone, and the SDK now enables dpp's validation feature.
Side effect: contract parsing with full validation requested now actually validates in every SDK built on rs-sdk. For example, wasm-sdk's DataContract.fromJSON validates by default. Two fixes came with it:
A wasm-sdk fixture with an indexed string lacking maxLength was fixed.
wasm-dpp2's DataContract constructor parsed document types before adding the contract's tokens, which refused a document paying in the contract's own token. It now parses them with the tokens.
Identities proved after their entries. The reader takes ProvedIdentity { identity, proved_at_height }. A snapshot proved before the latest block whose entry it checks, a missing identity, or one given under another id fails the read instead of judging the entry. Sdk::fetch_private_contact_request_identities fetches them four at a time and refetches a stale one once.
Protocol 15 first. The DashPay helpers and private_document_create_from_shielded_pool establish protocol version 15 before resolving DashPay or building the transition. A DashPay the context provider holds from before the private type is refetched and registered with the provider. A DashPay fetched from the network because the provider held none is registered the same way. If the provider still gives the old one afterwards, or none, the helper fails at once instead of failing every page's proof.
Contract bounds of encryption keys. dpp now owns the scope decision: ContractBounds::check_document_type answers Allowed, Denied, or "needs the contract group's members", which only state can answer. The SDK's existing encrypted_for key check, the signing key check and both encryption keys of a private request use it. A group bound is refused.
The sender's and recipient's encryption keys may be unbound, bound to DashPay, or bound to DashPay's contactRequest or privateContactRequest. contactRequest is allowed because DashPay requires bound encryption and decryption keys for it, and apps register their DashPay keys bound to that type. Keys bound to another contract, another DashPay type or a group are refused, in the seal and in the reader.
Stricter key checks.
Signing keys bound to another contract or to a contract group are refused.
Signing keys past expires_at are refused, at the entry's block time in the reader and at the device's clock when sealing.
A received entry's recipient key must be the key it is encrypted to.
A scan of another store is refused. An opened entry keeps the store it was opened for (contract_id, document_type_name), and private_contact_requests_from_scan refuses a scan holding an entry of any store but DashPay's privateContactRequest.
The reader's docs say what is not established: keys are those of the proved identity, which may be newer than the entry, and Platform records when a key was disabled, not when it was added.
The authenticated data names the recipient key, so an entry re-encrypted to another key of the identity authenticates no sender.
Smaller changes.
Recovered sent requests are deduplicated.
Senders sharing an outgoing viewing key are attributed by the key the entry names.
PrivateDocumentScanKeys::derive builds scan keys from key paths.
An OS RNG failure is an error, not a panic.
seal_private_contact_request(contract, sender, recipient, key_id, request, esk_seed)

Bigger private store chunks (protocol 15 limit, 84c2b96).SYSTEM_LIMITS_V5.private_document_store_target_chunk_bytes doubles from 512 KiB to 1 MiB, so a page of a private store carries about as many bytes as a 2048-note shielded chunk (2048 x 312 bytes, about 624 KiB). The chunk power is still clamp(floor(log2(target / stored entry size)), 4, 11), committed into each store when it is created. Protocol 15 is unreleased, so the table is edited in place and no store exists under 512 KiB.
DashPay privateContactRequest (589-byte entries, 605 bytes stored)
before: chunk power 9, 512 entries a page (about 302 KiB)
after: chunk power 10, 1024 entries a page (about 605 KiB); a full read takes half the requests
largest private entries (4096 bytes, 4112 stored)
before: chunk power 6, 64 entries a chunk (about 257 KiB)
after: chunk power 7, 128 entries a chunk (about 514 KiB)
Drive's store tests follow the new sizes. The paging fixture's entry count is now a u16, so its test still covers two compacted chunks and a buffered tail, and the changed-limits test now compares 1 MiB with 2 MiB.
The fixed-fee test appends 134 entries per entry size instead of 70, so it still crosses a chunk's compaction at 4096-byte entries.
Chunk size from the proof (8558e83). Drive's PrivateDocumentEntries gains chunk_power: Option<u8>, read from the store element the page's proof binds; Drive's read and proof verification fill it, and an unproved page leaves it None. The SDK's page walk takes it from the first proved page and fetches every later page at once, instead of learning the chunk size from page lengths with up to two sequential reads. A client-side read result: no consensus change, and no proto change.
sender verification, including an identity added with two key sets;
the cursor on an empty page;
a mock-fetched page.
private_contact_request:
schema bounds pinned to DashPay v3;
payload round trip, including the largest request, which fills the 589-byte entry exactly;
bound refusals;
seal, then read and recover;
sender refusals: encryption key and signing key, each disabled before and after the entry; wrong purposes; MEDIUM and MASTER levels; a ECDSA_HASH160 signing key accepted;
the recipient's own key produces no request from someone else: a MAC entry and a recipient-signed entry naming the sender are both refused;
recipient key disabled before the entry;
sent entries naming another key or identity, or signed by none of the sender's keys;
an unknown sender is refused before its payload is read;
anonymous and duplicate entries;
seal key refusals;
the signing levels are CRITICAL and HIGH;
a Signer that signs like SimpleSigner produces exactly the signature the entry carries;
signing keys bound to DashPay or its type sign, keys bound elsewhere or to a group do not;
encryption keys, the sender's and the recipient's, in the seal and the reader: unbound, bound to DashPay or to either contact request type are used; bound to another contract, another DashPay type, another contract's contactRequest or a group are refused;
the DashPay refresh: an unpinned SDK seeded at 14 whose provider holds DashPay from before the private type learns the network's version, fetches the current DashPay and leaves it in the provider; a provider already holding it is used without a fetch; a provider that keeps the old one, and a network without DashPay, fail;
a second recovered sent request for the same account reference is a duplicate;
an unknown property set to null is refused;
a scan of another contract's store with DashPay's types is refused, received and sent;
an account label over 63 bytes is refused even at 32 characters.
private_document_scan: senders sharing an outgoing viewing key recover an entry as the one it names.
transition: entries consensus refuses are refused before broadcasting; an unpinned SDK seeded at 14 learns the network's version before it builds the send, and builds it at that version.
dpp (cargo test -p dpp --lib contract_bounds): the document-type scope of single-contract, document-type and contract-group bounds.
platform-encryption (cargo test -p platform-encryption private_document, 13 tests): signer recovery, signatures of other data, non-signatures refused at seal, and the re-pinned signature-mode hash.
The DashPay refresh is tested with a test context provider; reading a full page is tested through the pure private_contact_requests_from_scan.
In-place changes to shipped generations
DocumentsBatchTransitionMethodsV0::combined_security_level_requirement (batch transition methods v0, every protocol version that authorizes document batches) now returns SecurityLevel::document_signing_levels() of its strongest requirement instead of computing the range inline. Consensus cannot change: the new helper returns, for every SecurityLevel, exactly the vector the old code built, namely [MASTER] for MASTER and CRITICAL..=requirement in the same order otherwise. The only other difference is that the unwrap in the old range conversion is gone. dpp tests pin the outputs for each of the four requirements, a mixed batch, a token batch and an empty batch.
Breaking Changes
One protocol 15 consensus limit changes before release: the private document store chunk target, 512 KiB to 1 MiB (SYSTEM_LIMITS_V5). No released protocol version is affected. Otherwise none for consensus. dpp gains ContractBounds::check_document_type and DocumentTypeBoundsCheck, a pure client-side helper that consensus does not call. The new SDK functions changed their signatures during review (see above); none had shipped. In platform-encryption, PrivateDocumentSender::Signature takes a signature instead of a secret key, the signature signs the double SHA-256 of the signing data, and the authenticated data of every mode names the recipient key. Nothing used these modes yet.

Summary by CodeRabbit
New Features
Added private-document scanning that classifies received, sent, and rejected entries, supports sender verification, and streams store pages.
Added support for creating private documents from shielded-pool funds and scanning private contact requests.
Private-document signatures now support signer recovery and verification.
Added checks for document-type access bounds and token configurations.
Bug Fixes
Improved protocol-version checks for private-document operations and handling of stale store pages.
Updated private-document store chunk sizing and page metadata.
Contract caches now retain newer versions when older versions are received.
The prepared-keys test also opens an entry with the first key of the
set, so a scan skipping earlier keys would fail it.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
The SDK can now append entries to a private document type's store, paid
from the shielded pool (type 29), and find a wallet's entries in it:
- `PrivateDocumentCreateFromShieldedPool` builds, structure-checks and
broadcasts the transition from a proven bundle, and waits for its
nullifiers to be proven spent.
- `PrivateDocumentScanKeys` and `Sdk::scan_private_document_page` sort a
proved page of a store into what the wallet's identities received
(their keys open it), what they sent (their outgoing viewing keys
recover it) and what opened but is refused, with the cursor to scan
from next.
- DashPay: `PrivateContactRequest` with the schema's bounds,
`seal_private_contact_request` (the sender's encryption key, a deniable
MAC, and the outgoing viewing key derived from that key), and
`Sdk::scan_private_contact_requests`, which decodes each request,
checks its sender against the identity key it names and keeps the
first request per sender, recipient and account reference.
platform-encryption: prepared recipient keys check a sender with the key
that opened the entry, so a scan never copies secret keys out.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
A wallet restoring its sent requests needs the encryption key each was
sealed with to rebuild its local record of the request.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
A private contact request carried a deniable MAC keyed by the static ECDH
of the sender's encryption key and the recipient's key. Anyone holding the
recipient's key could compute it, so a stolen recipient key forged requests
from any sender, including rotations that redirect the recipient's payments.
The request is now signed by one of the sender's signing keys, as its public
request's transition is: an enabled AUTHENTICATION key at a level DashPay's
documents are signed at (CRITICAL or HIGH), ECDSA_SECP256K1 or ECDSA_HASH160.
The entry still names the encryption key, which the pair's shared key and the
outgoing viewing key come from; the reader recovers the signing key from the
signature. Entries with a MAC are refused.
Envelope (signature mode, nothing deployed): the signature now signs the
double SHA-256 of the signing data, as identity signers sign data, so a
wallet signs with the signer it signs transitions with. The caller passes
the signature; `private_document_signing_data`,
`sign_private_document_signing_data`, `recover_private_document_signer` and
`OpenedPrivateDocumentEntry::recover_signer` are new. Prepared recipient keys
are wiped on drop.
Reading also checks, at the entry's block time, the recipient key it is
encrypted to, and that a sent entry names the identity and key its outgoing
viewing key comes from and is signed by that identity. The sender is checked
before the payload is decoded. `PrivateDocumentScanKeys::verify_sender`
tries every key set of the identity.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Signature-mode entries use caller-supplied recoverable signatures. Authentication data includes the recipient public key. Opened entries expose contract and document type details and support signer recovery.
The SDK resolves contracts that declare the requested private type. Private-document pages carry optional chunk power. Drive and verified reads provide chunk power; unproved responses use None. Page and chunk tests cover updated geometry.
Register keys and classify entries packages/rs-sdk/src/platform/private_document_scan.rs, packages/rs-sdk/src/platform.rs
The SDK adds scan-key registration and derivation, entry classification, sender verification, and scan results with store metadata and a next-position cursor.
Fetch and scan pages packages/rs-sdk/src/platform/private_document_scan.rs
The SDK streams pages in store order, discovers chunk size, and bounds concurrent fetches. It retries empty pages from behind snapshots and checks page geometry.

Summary
Map requirements to signing levels packages/rs-dpp/src/identity/identity_public_key/security_level.rs, packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/*
SecurityLevel::document_signing_levels returns levels for a requirement. Batch transition logic uses this method, with tests for document, token-only, and empty batches.
WASM Data-Contract Token Configuration
Layer / File(s)
Summary
Include tokens in contract parsing packages/wasm-dpp2/src/data_contract/model.rs, packages/wasm-dpp2/tests/unit/TokenConfiguration.spec.ts
The constructor inserts nonempty token configuration before parsing and rejects tokens for structure version 0. The setter rejects nonempty maps for that version. Tests cover token positions and version handling.

- Around line 913-917: Update the reader’s signing-key validation loop around

Review fixes:
- The envelope's authenticated data names the recipient key `ser(R)`, so
a body re-encrypted to another key of the same identity (an old key's
holder re-targeting a signed request) authenticates no sender.
`private_document_signing_data` takes the recipient. The MAC and
signature vectors are re-pinned; nothing is deployed.
- A signing key bound to a contract signs only inside its bounds:
DashPay, or its `privateContactRequest` type. A contract group bound
signs none, as a client cannot read the group's members as they were.
The seal and the reader apply the same rule;
`private_contact_request_signing_keys` lists the keys that qualify.
- `PrivateContactRequest::from_properties` drops a null only under an
optional property's name, so an unknown property set to null is refused.
- Recovered sent requests are deduplicated per sender, recipient and
account reference, apart from the received ones.
- Senders added with the same outgoing viewing key: an entry recovers as
the one it names.
- Docs: the transition's proof shows the nullifiers spent, not that its
entries were appended; fetching a sender right after its page tells the
serving node which identity the wallet looked up.

The private send picks the first signing key the signer holds among
`private_contact_request_signing_keys`, which adds the contract bounds rule
of #5809 to the level and type rules: a key bound to another contract or
document type, or to a contract group, is never chosen, as the seal would
refuse it.

Final validation — Phase 1 + Phase 2
Verified head 3d510b8 and confirmed three blockers: stale identity snapshots can bypass revocation checks, contract resolution precedes protocol discovery, and payload validation duplicates DPP-owned rules. The identity-fetch performance findings are combined into one suggestion. This was static review only; current CI reports passing Rust workspace, wasm32, JavaScript, Swift, and Kotlin checks, with PR Hygiene and the automated review pending.
Triage: critical by gpt-6.1-sol (effort low) — The large, intricate diff changes cryptographic signature handling in packages/rs-platform-encryption/src/private_document_envelope.rs and implements signing, key derivation, and verification in packages/rs-sdk/src/platform/dashpay/private_contact_request.rs.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.
In `packages/rs-sdk/src/platform/dashpay/private_contact_request.rs`:
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1097-1101: Require identity snapshots to cover the entries they authorize
Identity::fetch discards the verified response metadata, so this composition never establishes that an identity snapshot includes the block that appended its request. Fetching after the page is insufficient: SdkBuilder defaults to metadata_height_tolerance: Some(1), and get_identity uses that tolerance. After accepting a page at height H, the SDK can therefore accept an identity proof from H-1. If a compromised signing key is disabled in block H and an attacker appends a request in that same block, a malicious DAPI endpoint can return the genuine page from H alongside a saved identity proof from H-1. The reader then sees no disabled_at and authenticates the request, bypassing its rejection of keys disabled at or before the append time without either proof being forged. Fetch identities with verified metadata and require each snapshot to cover at least the maximum append height of the entries whose authorization depends on it; retry or fail when the snapshot is older. Add coverage for a page at H and an identity snapshot at H-1 containing the formerly enabled key.
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1026-1027: Discover protocol 15 before resolving the DashPay contract
A fresh unpinned SDK starts at protocol 13, or 14 on devnet. fetch_dashpay_contract first consults the context provider, and the bundled providers load DashPay using that current SDK version without contacting the network. This returns DashPay v1/v2, so private_contact_request_signing_keys fails because privateContactRequest is absent even when the network runs protocol 15; repeating the seal does not discover the newer version. scan_private_contact_requests has the same ordering problem at line 1088: its subsequent page fetch can discover protocol 15, but the final reader still receives the previously captured old contract. Require the feature's initial protocol version before resolving the contract in both helpers, following fetch_moderation_charters_contract's require_protocol_version pattern. Cover an initially unpinned SDK with a bundled context provider.
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:189-202: Delegate payload schema validation to DPP
check_bounds independently enforces accountLabel.maxBytes and autoAcceptProof.minItems/maxItems using SDK constants. These checks already belong to DPP's document-property validation, and the book's “Validation lives once” rule explicitly prohibits SDK copies of DPP length, range, and count checks. Both sealing and reading use this duplicate validator even though their codec receives a DataContract; the codec explicitly leaves schema-bound validation to DataContract::validate_document_properties. Pinning today's bundled schema in a test does not make runtime validation follow the supplied contract. Keep typed conversion in the SDK, but validate before encoding and after decoding through DPP-owned machinery. Enable the canonical validation entrypoint or expose a client-appropriate entrypoint in DPP backed by its existing native validation-schema implementation rather than maintaining another definition of valid payloads.
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:759-769: Prune identity dependencies and overlap independent fetches
This collector includes identities from anonymous and deniable-MAC entries, although EntryReader::check_sender rejects both modes before accessing any identity. The convenience scan then fetches every collected identity sequentially, including sender IDs supplied by entries it will reject. Such a page creates unnecessary proof-verified requests, an unrelated lookup failure can fail the entire scan, and N required identities incur N sequential round trips. Filter non-signature entries from both received and sent dependency collection, preserving their existing rejection results, then resolve the remaining independent identities with bounded concurrency. The SDK already uses buffered query concurrency elsewhere.
Your move: thepastaclaw requested changes on this head; dismiss the review or push a fix; thepastaclaw left review threads unresolved; resolve them.
Full checklist in the description.
…y heights
Review fixes:
- Requests are checked against their type's schema with dpp's document
validation (`DataContract::validate_document_properties`), before
encoding when sealing and after decoding when reading, as the payload
codec asks. The SDK's own copies of the label and proof bounds are gone;
`to_properties` is a typed conversion. The SDK enables dpp's `validation`
feature. `seal_private_contact_request` and
`private_contact_request_signing_data` take `platform_version` last.
- The reader takes each identity with the height its proof is of
(`ProvedIdentity`). `private_contact_request_identities` lists, per
identity, the latest block whose entry it checks; a snapshot proved
before it, which a node may serve within the SDK's height tolerance, or
one not given, fails the read instead of judging the entry against keys
as they were before it. Only signed entries need identities.
- `Sdk::fetch_private_contact_request_identities` fetches them four at a
time with their metadata and fetches a stale one once more.
- Both SDK helpers establish protocol version 15 before resolving DashPay,
so an unpinned SDK starting below it does not read a DashPay without the
private type.
- `PrivateDocumentScanKeys::derive` builds scan keys from key paths with a
derivation callback, wiping what it derives, for signers that keep keys.

Review fixes (with the SDK changes of #5809 merged in):
- A private request whose store fails after it was paid for is kept in
memory (`add_paid_sent_contact_request`): the contact it answers
establishes, so a retried accept adopts it instead of paying for another
reply, and the next add of the same request (the private sync recovers it
from the store) stores it. Before, the failed store left no request and no
contact, so the accept failed and a retry paid again.
- `PlatformWallet::accept_contact_request_replying_in_kind` takes what a
private reply is paid with as `payment`, a closure called only for a
private reply (`PrivateReplyPayment`: coordinator, seed, account, prover).
A public reply or an adopted one needs neither shielded support nor the
seed.
- The private sync checks each page against identities proved at or after
its entries (`ProvedIdentity`), fetching a few at a time only those it
lacks or holds from an older proof.
- Scan keys are built with the SDK's `PrivateDocumentScanKeys::derive`; the
crypto provider's seal takes `platform_version`, which the SDK's schema
validation needs.

Review fixes (with the SDK changes of #5809 merged in, which also resolve
DashPay only once protocol version 15 is established):
- `getPrivateDocumentEntries` loads the contract (`get_or_fetch_contract`)
before fetching a page, as the page's proof is checked against it and
the context provider holds a custom contract only once loaded.
- Secret keys read from the options are held in a guard that wipes them
when dropped, so an error parsing a later option wipes them too. The
seal reads the encryption key after every other option.
- The scan's docs, and the evo-sdk facade's, say it fetches the identities
the page's requests are checked against right after the page, which a
node serving both can correlate.
- The shared `secret_key_from_options` and `try_to_fixed_bytes` replace
the local helpers.

Re-review — Final validation — Phase 1 + Phase 2
Verified head d4efa2e: all four prior findings are fixed, but blocking issues remain in standalone protocol discovery, signing-key expiry enforcement, and CI compatibility after enabling DPP validation. Current CI confirms 15 WASM contract-fixture test failures caused by the newly activated validation; Rust workspace tests remain pending, while the JS build, wasm32, Kotlin, and Swift schema checks passed.

- [BLOCKING] packages/rs-sdk/src/platform/transition/private_document_create_from_shielded_pool.rs:95-101: Discover protocol 15 before building standalone private submissions
This independent async sending API invokes the synchronous builder before discovering the network protocol version. A fresh unpinned SDK starts at protocol 13, or 14 on devnet; the builder then structure-checks against historical SystemLimits where max_private_document_entries_per_transition is None. DPP interprets that limit as zero and rejects every nonempty batch with InvalidPrivateDocumentEntryCountError before any network request can update the SDK. Consequently, already sealed entries and proven bundles prepared offline or restored for retry cannot be submitted even to a protocol-15 network, and repeating the call cannot recover. The gate in the DashPay seal/scan helpers does not cover this route. Await require_protocol_version with PRIVATE_DOCUMENT_CREATE_FROM_SHIELDED_POOL_INITIAL_PROTOCOL_VERSION before invoking the builder. Preserve the synchronous builder's explicit-version behavior and DPP's historical rejection, and add coverage for direct submission from an initially older unpinned SDK.

- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:599-600: Reject signing keys expired at the request's append time
Signing-key eligibility ends with disabled_problem, which checks only disabled_at. IdentityPublicKey::V1 also carries expires_at, and DPP defines the expiry instant itself as expired through IdentityPublicKeyGettersV1::is_expired_at. A HIGH AUTHENTICATION key with disabled_at = None and expires_at = T therefore remains eligible here for an entry appended at or after T. EntryReader::check_sender accepts its recovered signature, and private_contact_request_signing_keys continues offering it, although the public transition path rejects an expired key with PublicKeyExpiredError. A holder of an expired delegated key can thus continue producing authenticated private requests. Reuse DPP's expiry predicate with the entry's authenticated block_time_ms, and give selection/sealing an explicit time context so they enforce the same policy. Cover V1 keys immediately before, at, and after expiry while preserving requests appended before expiry.
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1159-1166: Exercise the metadata-aware identity resolver in regression tests
The new height regression constructs ProvedIdentity values directly and exercises private_contact_requests_from_scan, but no test invokes fetch_private_contact_request_identities. It therefore does not cover preservation of verified response metadata, retrying a stale first response, or the distinction between a fetch failure and a proved absent identity. Add deterministic resolver-level tests for H-1 followed by H, two responses at H-1, a fetch error, and a sufficiently recent proved None. Assert that stale responses never produce a usable identity map and that a successful retry preserves the second response's identity and height. A small injectable fetch helper or metadata-capable mock can exercise the actual async control flow without network calls.
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1114-1115: Return an error when OS entropy cannot seed the RNG
StdRng::from_os_rng explicitly panics when getrandom cannot provide entropy. That environmental failure bypasses this Result-returning sealing API and can terminate its host rather than returning a seal error. Use try_from_os_rng and propagate the failure through Error; this preserves secure failure without introducing an insecure fallback.

Enabling dpp/validation here also enables it in wasm-sdk's shared DPP dependency, activating checks that DataContract.fromJSON(..., true, ...) previously skipped. The existing V0 crypto-card fixture indexes rarity but gives that string no maxLength; DPP's generation-0 index validation requires an indexed string to have maxLength <= 63. The current 'JS packages (Evo SDK packages) / Tests' check fails in job 128769208640 with 15 WASM tests reporting "Indexed property 'rarity' for 'card' document has an invalid constraint 'maxLength', reason: 'should be less or equal 63'" at 15:06:12, followed by '@dashevo/wasm-sdk exited with 15'.

… tests
The protocol gate vectors proved a network at 13 or 14, or at a version
newer than any build. The private document requests need 15, so the
SDK could not show a proved answer at 15 lifting a refusal. The exporter
now also writes `epoch-probe-pv15.bin`, the genesis epoch proved by a
protocol 15 state and signed at 15, and the vector check verifies it
under the rules of 13, 14 and 15. Re-running the exporter rewrites the
other vectors byte for byte.

…e requests too
DashPay's private contact request scan and seal resolved their contract
after `require_protocol_version`, which only refreshes the SDK's version:
with proofs off the refresh asks nothing, so an unpinned SDK below 15
failed with a generic error without asking the network, although the
gate's probe asks for a proof whatever the proof setting.
The send's order is now one helper, `Sdk::establish_protocol_requirement`:
the gate first, under the caller's request settings, then, only for an
SDK that enforces no gate (a mock) and is still below, a refresh under
the same settings, then the structured refusal. The send and DashPay's
contract resolution both use it, so the scan and seal refuse below 15
with `ProtocolVersionNotActive` rather than a generic error.
`require_protocol_version` is unchanged for the features that use it.

Keep Swift contract byte borrows alive through the FFI call — In packages/swift-sdk/Sources/SwiftDashSDK/SDK.swift:435–438, loadKnownContracts retains pointers returned by Data.withUnsafeBytes and passes them to Rust after those borrowing closures have ended. packages/rs-sdk-ffi/src/sdk.rs:757–766 dereferences these pointers with slice::from_raw_parts. Retaining the Data objects does not extend the documented pointer lifetime, so this exposes Rust to potentially invalid memory. Both sides are unchanged by this PR.
Follow-up: Address this in a separate follow-up PR by keeping all byte borrows active throughout dash_sdk_add_known_contracts, or by using explicitly owned temporary buffers whose lifetimes bracket the synchronous FFI call.
…t to 1 MiB
A private store's chunk power is clamp(floor(log2(target / stored entry
size)), 4, 11), committed into the store when it is created. At a 512 KiB
target DashPay's privateContactRequest store (589-byte entries, 605 bytes
stored) took chunk power 9: 512 entries, about 302 KiB a page, half the
bytes of a 2048-note shielded chunk (2048 x 312 bytes, about 624 KiB).
SYSTEM_LIMITS_V5.private_document_store_target_chunk_bytes is now 1 MiB:
DashPay's pages hold 1024 entries (about 605 KiB), so reading its store
takes half the requests, and 4096-byte entries take 128 to a chunk instead
of 64. Protocol version 15 is unreleased, so the table is edited in place
and no store exists under the old target.
Drive's tests follow the new sizes:
- the empty store, the layout and the chunk power tests expect power 10
for 601-byte stored entries and 7 for 4112-byte ones;
- the paging fixture's entry count is a u16, so the paging test still
covers two compacted chunks and a buffered tail at 128 to a chunk;
- the changed-limits test compares 1 MiB with 2 MiB;
- the fixed-fee test appends 134 entries per size instead of 70, so it
still crosses a compaction at 4096-byte entries.

Enforce the account-label byte limit for accepted sealer calls.
With a DashPay v3 contract and protocol 13, seal_private_contact_request can seal 32 é characters. The label is 64 UTF-8 bytes, above the 63-byte limit, because protocol 13 disables the byte check.
Reject this unsupported version combination before sealing, or enforce the bound through the existing document-type validation owner for accepted calls.

…tore's new chunk power
DashPay v3's privateContactRequest store now takes chunk power 10 under the
1 MiB chunk target (84c2b96), and the store element carries its chunk
power, so the root after inserting the contract at protocol version 15
moves. Only the latest-version pin changes.

…oots after the chunk target change
The settled characterization hashes and the single-entry root cover GroveDB
roots at PlatformVersion::latest(), whose genesis inserts DashPay v3 and its
privateContactRequest store. That store element carries its chunk power,
now 10 under the 1 MiB chunk target (84c2b96), so the roots move.
The shielded test phase passed with the old pins at 50658b5, and the only
change since that reaches drive-abci is the limit. All nine validation
hashes, which do not depend on roots, are unchanged; the nine settled hashes
and the single-entry root are re-pinned from one run with the settled check
skipped, then checked with it restored.

… finds none
GrpcContextProvider::get_data_contract fetches a contract it does not hold.
When the fetch found none it returned None, even if another operation had
registered the contract while the fetch ran, so a page verification could
fail on a contract the cache held. It now reads the cache again on that
path, as the found path already keeps a newer registered contract.

(cherry picked from commit f7a1204)
Upstream #5809 increases private_document_store_target_chunk_bytes from
512 KiB to 1 MiB, changing the activation root when the current system
contracts are rebuilt. A single-setting 512 KiB control restores the
original root under GroveDB V4 and V5, including after commit.
Re-pin only the coordinator-approved activation root; test logic stays
unchanged. Bounded comparisons preserve retained profile/contactInfo
subtrees and isolate our proposal history marker and empty history tree
against current upstream.
The original test fails before this expectation update and passes after.
Brings in 22 commits of v5.1-dev up to 9b36712 (#5821).
Conflicts:
- rs-sdk-trusted-context-provider/src/lib.rs: keep both modules,
`known_contracts` (#5809) and `local` (this PR).
- rs-sdk-trusted-context-provider/src/provider.rs and local.rs: #5809
(a8b4b49) gave each provider's contract cache one rule,
`hold_unless_newer_held`: adding, hydrating and registering a contract
keeps a held contract of a higher version. It also added
`replace_known_contract` for an explicit replacement. Here the trusted
provider's cache is `LocalContextResolver`, so the rule moves into the
resolver, which stays the single owner of the cache:
- `add_known_contract`, `add_known_data_contract` (the resolver's
`ContractSource::register_data_contract`, which the SPV and adaptive
providers use) and `add_known_contracts` go through
`hold_unless_newer_held`;
- the resolver gains `replace_known_contract`, and the trusted
provider's methods delegate to it;
- `add_known_contract_if_newer` is unchanged.
This replaces this PR's earlier choice that a registration overwrites
(0e7dab3). v5.1-dev's `ContextProvider::register_data_contract` now
asks every provider to keep a newer held contract, and the moderation
flow registers the contract's current version. An equal version now
replaces the held body in a bulk preload too, as in both providers'
caches; the preload test's equal-version case asserts that. Both sides'
tests are kept. #5809's two provider tests import
`DataContractV0Getters` locally, since the module no longer does.
- rs-sdk/src/sdk/protocol_gate_tests.rs: #5769 (0a38441, via the
v5.0-dev merge 356be94) and #5809 added tests. The helpers and the
NoQuorumSource / NoContractSource tests are kept. Dropped, because the
SDK's context provider is fixed and non-optional here, so the state
cannot be built:
- `should_refuse_without_asking_when_answers_cannot_be_verified`;
- `should_fail_a_proved_fetch_once_and_ban_no_node_without_a_context_provider`;
- the "without a context provider" case of
`should_not_take_a_version_verified_earlier_as_the_network_below_now`.
Adapted outside the conflicts:
- wasm-sdk/src/private_contact_requests.rs (#5811): two tests called
`Sdk::set_context_provider`, which this PR removes. They pass the
context to `SdkBuilder::with_context_provider` instead.
- rs-sdk/src/error.rs (#5769): the "context provider is not set" message
no longer names `Sdk::set_context_provider`.
- Docs: `dash_sdk_add_known_contracts` (an older contract is ignored, no
longer "not newer"), `ContractSource::register_data_contract` (keeps a
newer held contract, as the trait asks), and the `known_contracts`
module.
`TrustedHttpContextProvider` still reports no `network()`: #5766 is an
open issue, not part of v5.1-dev.

… registration
The v5.1-dev merge moved #5809's keep-newer rule into
`LocalContextResolver`, so `ContractSource::register_data_contract`,
the only way the SPV and adaptive providers register a contract, went
from overwriting to keeping a held contract of a higher version. Only
the trusted provider's tests checked the rule; the resolver's own test
registered into an empty cache.
The new test registers versions 2, 3 and then 2 through the
`ContractSource` path, expects 3 to stay, and expects
`replace_known_contract` to replace it.
Test would catch a regression:
should_keep_a_newer_contract_over_a_registered_older_one
✖ with `add_known_data_contract` overwriting again, as before the
merge: "an older registration does not" (left: Some(2), right: Some(3))
✔ as merged (cargo test -p rs-sdk-trusted-context-provider
--all-features --lib: 155 passed; default features: 142 passed)

Basic explanation
What this does: the Rust SDK can now send and find DashPay private contact requests.
PrivateContactRequest, sealing one, and a reader that checks each request against its sender's and recipient's keys.A private request is signed by one of the sender's signing keys, as a public request's transition is, with the same identity signer. The signature sits inside the encrypted entry: only the recipient sees it.
Value: this is the client half of anonymous DashPay contact requests (protocol version 15). Until now the chain could store private entries (#5799, #5804) and the envelope could seal and open them (#5806), but nothing in the SDK sent the transition or walked the store. Wallets, wasm-sdk and the mobile SDKs build on these calls.
Risks: low. It is client code apart from one protocol 15 limit: a private document store's chunk target doubles from 512 KiB to 1 MiB, so DashPay's pages hold 1024 requests instead of 512. Protocol 15 is unreleased, so no store exists under the old number. It also changes the envelope's signature mode in
platform-encryption(#5806). Nothing uses that mode yet and nothing is deployed, so the change breaks nothing.Issue being fixed or feature implemented

The chunk power is stillclamp(floor(log2(target / stored entry size)), 4, 11), committed into each store when it is created. Protocol 15 is unreleased, so the table is edited in place and no store exists under 512 KiB.u16, so its test still covers two compacted chunks and a buffered tail, and the changed-limits test now compares 1 MiB with 2 MiB.PrivateDocumentEntriesgainschunk_power: Option<u8>, read from the store element the page's proof binds; Drive's read and proof verification fill it, and an unproved page leaves itNone. The SDK's page walk takes it from the first proved page and fetches every later page at once, instead of learning the chunk size from page lengths with up to two sequential reads. A client-side read result: no consensus change, and no proto change.How Has This Been Tested?

Consensus cannot change: the new helper returns, for everySecurityLevel, exactly the vector the old code built, namely[MASTER]for MASTER andCRITICAL..=requirementin the same order otherwise. The only other difference is that theunwrapin the old range conversion is gone. dpp tests pin the outputs for each of the four requirements, a mixed batch, a token batch and an empty batch.Breaking Changes
One protocol 15 consensus limit changes before release: the private document store chunk target, 512 KiB to 1 MiB (
SYSTEM_LIMITS_V5). No released protocol version is affected. Otherwise none for consensus. dpp gainsContractBounds::check_document_typeandDocumentTypeBoundsCheck, a pure client-side helper that consensus does not call. The new SDK functions changed their signatures during review (see above); none had shipped. Inplatform-encryption,PrivateDocumentSender::Signaturetakes a signature instead of a secret key, the signature signs the double SHA-256 of the signing data, and the authenticated data of every mode names the recipient key. Nothing used these modes yet.Checklist:
