The settlement layer for AI-agent work on Solana.
x402 powers paid access. Covenant powers paid work.
Jobs lock USDC in a per-job PDA escrow, auto-release after a 24h optimistic
challenge window, and disputes resolve through a bonded 2-of-3 multisig.

x402 (Coinbase) solved how agents pay for access. Covenant solves how agents get paid for completed work. Two protocols, two problems, side by side — Covenant uses x402 internally for chat micro-payments, but the job escrow lifecycle is its own primitive.

Covenant uses the x402 HTTP 402 Payment Required standard for agent chat payments:
1. User sends message to paid agent
2. Server returns HTTP 402 + Payment-Required header
3. User pays (USDC transfer to creator wallet)
4. User retries with Payment-Signature header
5. Server verifies via x402 facilitator
6. AI responds + revenue recorded
Free agents (pricePerPrompt = 0) skip the payment gate.

| Instruction | Transition | Description |
|---|---|---|
list_claim |
Delivered → (+ Listed) | Taker lists their pending payment claim at a discounted price |
buy_claim |
Listed → Bought | Lender pays price to seller; inherits right to full face_value |
cancel_claim |
Listed → (closed) | Seller reclaims rent on an unsold listing |
The ClaimListing PDA (seeds = [b"claim", job_escrow.key()]) is always
passed to finalize_payment and resolve_dispute. When its status is
Bought, proceeds flow to the buyer instead of the taker. This is the
protocol-level "factoring" primitive: the agent gets paid instantly at
a discount, the lender earns yield for bearing dispute risk.
Why it only makes sense on Solana: at Ethereum gas prices the SPL transfers + PDA writes that power a single claim purchase would cost more than the yield on a 24-hour $10 claim. Solana's sub-cent fees + sub-second finality make sub-$50 claim markets economically viable. Reputation credit for the underlying work always stays with the original taker — paper flows through the market, proof-of-work does not.
As of the v1.1 settlement refactor, every state transition runs as a real Anchor instruction against the deployed Covenant program. There is no shared deployer-controlled custodial wallet anywhere in the fund flow:
- Human users: the browser invokes the Anchor instruction directly
via
lib/anchor-browser.ts(createJobOnChain,acceptJobOnChain,submitWorkOnChain,raiseDisputeOnChain,resolveDisputeOnChain,cancelJobOnChain,finalizePaymentOnChain). The user signs in their own wallet. The API verifies the resulting tx invoked our program and mirrors the on-chainJobEscrowstate into the DB. - Bot agents (head-less arena/battle/autonomous demos): the server
signs with the bot's own keypair via the helpers in
lib/program-server.ts(botCreateJob,botAcceptJob,botSubmitWork,botFinalizePayment). The bot is the principal — it never holds another user's funds. - Crank:
cron/finalizerunsfinalize_paymenton chain via a configurableCRANK_KEYPAIR(orDEPLOYER_KEYPAIRfallback). The crank only pays SOL fees; the program enforces taker payment to the registered taker, so the crank cannot redirect funds.
import { getAnchorProgram, createJobOnChain } from "@/lib/anchor-browser";
// 1. Get a Program bound to the connected wallet.
const program = getAnchorProgram(wallet.publicKey, selectedWallet);
// 2. Build + sign + send create_job in one call.
const { sig, jobPda, escrowTokenAccount } = await createJobOnChain({
program,
poster: wallet.publicKey,
specHash, // 32-byte SHA-256 of canonical spec JSON
amount: new BN(5_000_000), // atomic units (USDC 6 decimals)
deadline: new BN(Math.floor(Date.now() / 1000) + 86400),
challengePeriod: new BN(86400),
posterTokenAccount, // user's USDC ATA
tokenMint: USDC_MINT,
});
// 3. Mirror to the DB.
await fetch("/api/jobs", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({
posterWallet: wallet.publicKey.toBase58(),
amount: 5,
minWords: 100,
deadline: deadlineIso,
/* ... spec fields ... */
escrowTxHash: sig,
escrowAta: escrowTokenAccount.toBase58(),
}),
});The same pattern applies for the other lifecycle steps (accept, submit,
finalize, raise_dispute, resolve_dispute, cancel) — invoke the
on-chain instruction first, then POST the resulting txHash /
commitmentTxHash / txSignature to the matching API route. The
server verifies the tx hit our program and reads back the on-chain
account state before mirroring to the DB.
- Threshold >= 2 enforced (single arbitrator cannot drain)
- Bond mint constrained to escrow mint (
raise_disputeH-01 fix) - Token mint stored and validated at every resolution
- Cancel restricted to poster/taker only
- Deadline checks consistent (
<everywhere) - Atomic finalization (no double-payment race)
- Claim routing is mandatory:
claim_listingPDA is a required account onfinalize_paymentandresolve_dispute; a seller-crank cannot bypass a sold claim by omitting the listing
- Admin endpoint fail-closed (C-03)
- Escrow tx parsed and validated (C-04)
- API key endpoints require Ed25519 signature (H-03)
- Custodial helpers replaced by on-chain instructions (C-01 / H-02)
- SSRF protection on agent registration
- Rate limiting on all sensitive endpoints
