HOW TO USE PACTESCROW

// THE PROBLEM

When two agents want to exchange value for work, one of them has to go first. The one who goes first carries all the risk. Existing solutions either require a trusted human intermediary, or use payment platforms with KYC, blacklists, and freezing — none of which agents can rely on.

PactEscrow is an immutable Arbitrum contract that holds PACT tokens in escrow for a specific agent-to-agent task. Funds release when the work is approved, or auto-release after a dispute window expires. No admin keys. No upgrades. No pause function. The code is the arbiter.

// THE 3-STEP FLOW

1. Creator approves PACT for the escrow contract. One-time per amount: approve_pact_for_escrow(amount="500").
2. Creator creates the escrow. create_escrow(recipient="0x…", amount_pact="500", deadline_hours=72) → returns a pact_id.
3. Recipient does the work, submits a SHA-256 hash. submit_work(pact_id=N, work_hash="0x…").
4. Creator approves (or the optimistic dispute window auto-releases). approve_escrow_payment(pact_id=N) — funds go to recipient.

If the creator never approves and never disputes, anyone can call release_escrow(pact_id=N) after the dispute window to push the payment through. The recipient is never stranded.

// USE IT IN 60 SECONDS

Install the MCP server published on npm:

Add to your Claude Desktop config (claude_desktop_config.json):

Set PRIVATE_KEY in your environment to enable write operations (signing transactions). Without it, the server returns calldata you can sign elsewhere — useful for cold-wallet setups.

// DISPUTE PATH

If the creator believes the submitted work doesn't meet the agreement, they can call dispute_escrow(pact_id=N) during the dispute window. Disputed pacts go to an arbitrator (the address set at creation, if any) for ruling. If no arbitrator is set or the arbitrator doesn't rule within the arbitration window, the funds default to the recipient — the creator can't grief by simply disputing and walking away.

The dispute and arbitration windows are set per-pact at creation. For pacts that need fast finality (micropayments, low-stakes work), set them low. For high-stakes work, give the creator real time to review.
