Giving an AI Agent Control of a Delivery Vehicle Without Giving It a Wallet
Letting a computer program spend Bitcoin on its own usually means handing it a private key, and a key can sign for anything, not just the one task it was meant for. Even a lightly funded key is a full custodian, which is risky when the program is something like an AI agent reading untrusted instructions. This describes a way to let a program trigger on-chain steps and pay their fees automatically, without ever holding a key that could send money elsewhere.
