An independent builder. Its current product is UNICA.
UNICA is an MIT-licensed settlement hook and modular integration layer for Uniswap v4. A payer pays in one currency, a recipient receives another, in one transaction, through Uniswap's official Universal Router, into a pool whose hook admits a swap only on that path and only for a registered order, and which emits a versioned receipt.
UNICA is testnet only. There is no mainnet deployment and no real value at risk. No part of it has been audited.

| Release | State | What is true |
|---|---|---|
| V1 | live, testnet | Live on Ethereum Sepolia. Source-verified on Sourcify as a partial match. One settlement: 0.001 ETH in, 2.003660 USDC out. |
| V2 | blocked | Written and frozen as rc1, deployed nowhere. Held back by an internally identified Critical finding, published as Security Advisory 001. |
| V3 | live, testnet | Settled on Ethereum Sepolia: 0.001 ETH in, 2.216294 USDC out. A second settlement ran in a browser, where the merchant was a name, nfteria.eth, resolved on ENSv2 Sepolia and shown to the payer before signing. Deployed and source-verified at one address on Ethereum, Unichain, Base and Arbitrum Sepolia; it has settled only on Ethereum Sepolia. |
| Experimental | testnet, outside the release line | One order settled on Robinhood Chain testnet (chain 46630) on 2026-09-11 through a separate experimental hook: 0.001 Robinhood test TSLA in, 0.393052 uTUSD out. Robinhood test tokens have no real-world value, and neither does uTUSD. There is no oracle in that path, and its source is not verified on the explorer. |
| v4 | designed | Being designed. Not built, not deployed. It will be a separate deployment with its own addresses, not an upgrade of anything above. |
"UNICA v4" is a UNICA release name. It is not Uniswap v4, the AMM UNICA is built on.
Access0x1 — built for ETHGlobal New York and ETHGlobal Lisbon. An MIT-licensed, non-custodial rail for onchain identity and USD-priced payments in USDC, with a merchant layer over it. Its own repository states where it stands: testnets only, no mainnet deployment, no token, and a first-party self-audit by its maintainer rather than an external audit. UNICA is separate work, written from scratch, and shares no code with it.
Organization files only: this profile page, the security policy, and the privacy statement. Product code lives in its own repository.
