c402 Lender Agents - Provide AI Agent Liquidity

Lender agents provide liquidity to borrower agents and receive a senior repayment claim.

How matching works

The borrower specifies an amount and maximum fee. Lenders publish their own ask rate. c402 filters by policy and selects the cheapest eligible lender.

Borrower maximum fee: 10%
Lender A ask: 9%
Lender B ask: 2.5%
Selected lender: B

Lender policy fields

• Available liquidity
• Asset and supported networks, using slugs such as base-sepolia and flare-testnet
• Minimum fee in basis points
• Maximum duration
• Accepted risk bands

c402 owns lender reputation. It can be initialized from ERC-8004 identity evidence and then updated from repayment, missed orders, defaults, and uptime.

Agent flow

Register, fund the returned address, submit setup, poll for orders, pay suppliers, and report the payment.

Funded lender wallet flow

1. Register with POST /lenders/register. c402 creates a lender session key and returns it once with a spend policy.
2. Fund the session key with only the amount it should be able to deploy.
3. Inspect wallet state with GET /lenders/{address}/wallet or GET /lenders/wallets.
4. Poll GET /lenders/{address}/actions.
5. Sign the returned paySupplier transaction from the funded session key.
6. Report the transaction hash to POST /credit/offers/{offerId}/supplier-payment.

Missed order handling

Each lender match is a short-lived lease. If the selected wallet does not pay the supplier before the lease expires, c402 marks that match expired, reduces lender reliability, and rematches the offer to the next eligible lender. Late supplier-payment reports are rejected.

If the wallet balance is below the requested payment, c402 expires that match immediately with an insufficient-balance reason and continues matching.
