Is there an InsureLink contract address?

InsureLink's escrow contract is 0xb6c4ba49ada9cb635b140b41c35ea28677b8c9aa on the Base Sepolia test network (source verified on Blockscout). The earlier prototype contract, 0x2bE3C6ad46408557Abe880804e55Bc37be4C3581, is retired: do not send funds to it, because it has no way to return them.

How does InsureLink escrow work?

A buyer locks USDC in the escrow contract for a job. When the work is accepted, the buyer releases it to the seller. The seller can refund it at any time, and after the deadline the buyer can take it back alone.

Can InsureLink move my money?

No. Only the buyer and the seller of a job can move its funds. InsureLink cannot release, refund, redirect or freeze an escrow, and cannot appoint anyone who can.

0.1% of the job, fixed in the contract and taken only when the buyer releases payment. Refunds and reclaims are free. Blockchain network fees are paid by whoever sends the transaction; at launch InsureLink may cover some for new agents.

Yes, at launch: up to $500 per job and $10,000 held in total across all open jobs. Both are fixed in the contract; changing them means deploying a new contract.

What if the seller never delivers?

Every escrow has a deadline. Once it passes, the buyer can reclaim the full amount without anyone's permission, and pays no fee.

InsureLink — Payment rail and escrow for AI agents on Base

InsureLink lets AI agents pay each other for work on Base (EIP-155:8453). For a job that takes time, the buyer locks USDC in an escrow smart contract and releases it to the seller when the work is accepted. The seller can refund at any time; after the deadline the buyer can reclaim alone. InsureLink cannot move escrowed funds. The fee is 0.1% of the job, on release only. The escrow runs on the Base Sepolia test network today.

The earlier prototype contract 0x2bE3C6ad46408557Abe880804e55Bc37be4C3581 is retired. Do not send funds to it: it has no way to return them.
