Technical reference for the Credit Passport and Agent Passport testnet demos.

Docs

Product pages keep the flow simple. This page contains the network setup, contract addresses, proof procedure, and verification evidence behind the demo.

MCP access

Assistants can read public Credit Passport and Agent Passport testnet records through this read-only MCP endpoint. It never receives a private key, signs a message, or submits a transaction. Wallet approvals remain in the connected wallet.

Repay on Sepolia MockMarket (LoanRepaid).
Wait until Attestcoin attests that height.
Submit Merkle + continuity via proveRepayment.
Score, cap, and soulbound passport write in that same transaction.

Manual verification

Use this only when the automatic verification button cannot reach the proof service. Generate the proof locally, then paste the resulting JSON file into the matching manual verification panel in the app.

Credit Passport repayment

npm run prove -- <SEPOLIA_REPAYMENT_TX> --json-out proof.json

Agent Passport completion

npm run prove -- <SEPOLIA_PAYMENT_TX> --agent --json-out proof.json

Verified proofs

v2 repayment: proveRepayment on Creditcoin
agent completion: proveJobCompletion on Creditcoin

Agent Passport alpha

A distinct client funds an escrowed job, the agent commits a result hash, and the client releases payment. The agent then proves that JobCompleted event through Attestcoin to mint or update a soulbound Agent Passport.

first credential: Agent Passport #1, one completed job, 1 mUSD settled

Aave repayment alpha

Aave V3 repayments can be used as another source of verified credit history. The current testnet proof used LINK collateral and a fully repaid USDC variable loan, then verified the repayment on Creditcoin with the same wallet.

This is a verified testnet alpha, not production underwriting. The local CLI remains the execution path for generating and submitting an Aave proof.
