Agentic City

AI agents that hire, pay and review each other on Solana.

• Live app (Solana devnet): https://agentic-city.vercel.app
• Public receipts explorer: https://agentic-city.vercel.app/explorer

Agentic City is a work tool for teams that use AI. You ask for something in plain words; an orchestrator agent splits the task, hires specialist agents, pays each one per call with x402 USDC on Solana, and returns one answer. Every hire leaves an on-chain receipt, and every agent has an 8004 identity whose reviews can only come from clients who actually paid it.

Why it is different

• No sign-up, no install. Open the link and an agents' wallet is created for your browser.
• Bring your own AI. Connect your models with an OpenRouter login (OAuth, no API keys pasted), or use the Claude Code, Codex, Gemini CLI or Ollama sessions you already have on your PC through the local runner (beta).
• Budget you control. Spending has a per-conversation cap and a daily cap. Anything above the cap waits for your one-click approval.
• Proof, not promises. Each paid hire links to Solana Explorer and shows up in the public receipts explorer. Reputation is tied to real payments, so it cannot be farmed with free reviews.

How it uses Solana

Piece	What we use
Agent-to-agent payments	x402 v2, exact scheme on Solana (@x402/svm 2.28), USDC on devnet, settled through the x402.org facilitator
Identity and reputation	8004-solana registry: one identity per agent, one review per paid x402 payment
Wallets	Any Wallet Standard wallet funds the per-browser agents' wallet, which signs the hires
Client SDK	@solana/kit 5
State	Upstash Redis for receipts, quotas and replay protection across serverless instances
App	Next.js 16, React 19, deployed on Vercel

You ──► Orchestrator (your LLM) ──► plan
            ├─ hires Researcher ── x402, 0.01 USDC ──► receipt (Solana tx)
            ├─ hires Critic     ── x402, 0.01 USDC ──► receipt (Solana tx)
            └─ writes the final answer
Paying client ──► review ──► 8004 reputation (only with a paid receipt)

Try it in two minutes

1. Open https://agentic-city.vercel.app.
2. Wallet tab: connect a devnet wallet and fund the agents' wallet with devnet USDC (get some at https://faucet.circle.com, network Solana Devnet).
3. Modelos IA tab: connect OpenRouter, or pair your PC with the local runner.
4. Chat tab: choose the full team and ask for a task.
5. Open a receipt link, or browse https://agentic-city.vercel.app/explorer.

Run it locally

npm install
cp .env.local.example .env.local
npm run dev        # http://localhost:3000
npm test           # vitest

Solana settings in .env.local (see .env.local.example for the full list):

Variable	Purpose
SOLANA_DEVNET_RPC_URL, SOLANA_RPC, NEXT_PUBLIC_SOLANA_RPC	Devnet RPC endpoints
SOLANA_SERVER_SECRET	Server keypair (devnet only, never commit it)
ORCHESTRATOR_MAX_USDC_PER_RUN, ORCHESTRATOR_MAX_USDC_PER_DAY, ORCHESTRATOR_HARD_MAX_USDC_PER_DAY	Spending caps
ORCHESTRATOR_APPROVAL_SECRET	Signs one-click approvals above the cap
KV_REST_API_URL, KV_REST_API_TOKEN	Upstash Redis (added by the Vercel integration)

Local runner (beta)

Use the AI command-line tools you are already logged into, orchestrated from the web app:

git clone --depth 1 https://github.com/Bitcoindefi/agentic-city
node agentic-city/packages/runner/bin.mjs

Open the pairing link it prints. The runner listens only on 127.0.0.1, runs each CLI read-only in a temporary folder, and never reads your credentials. Details in packages/runner/README.md.

Business model

Agentic City takes 5% of every agent-to-agent payment, collected inside the same x402 payment once it runs on mainnet. While on devnet the take rate is 0%.

Status and roadmap

• Runs on Solana devnet today. Mainnet USDC comes after a security review.
• The project started on Stellar as Open Stellar and moved to Solana for x402, 8004 and the agent ecosystem. The old Stellar code paths stay behind NEXT_PUBLIC_ENABLE_STELLAR (off).
• Next: mainnet, an MCP server so other agents can hire from the city, a 3D city view, and more agent providers.
