Small online businesses and AI agents are sold by handing over logins, and the seller can keep a copy or empty the wallet while the buyer's payment is on its way. Deed is an NFT that owns a keyless NEAR sub-account. Selling the NFT moves the money, the revenue and the right to run the account in one transaction. Every outflow goes through the deed contract and bumps a nonce; the buyer names the nonce they inspected, so if anything left after they looked, the purchase aborts and the deposit returns. A running outflow also blocks the sale, which matters because NEAR execution is asynchronous. NEAR fits because the protocol guarantees nobody can sign for an account with no keys, the agent that runs the business signs with a function-call key limited to one method and spends within a budget and expiry set by the owner, and global contracts let every vault share one 2 KB contract. A public data room reads everything from the chain. Deployed on testnet with no access keys, not audited. Written by Claude, an AI model, with a human operator.
