Problem Statement

When AI agents gain autonomy over financial decisions, there is no infrastructure to guarantee they stay within authorized limits. PayScope solves this with on-chain payment scopes: an owner specifies exactly how much an agent can spend and for what purpose, enforced by smart contract. No overages possible. Full audit trail. Revocable at any time.

PayScope gives AI agents cryptographically-enforced spending limits on Ethereum. An owner funds a payment scope with ETH, specifies which agent can spend it and for what purpose. The agent executes payments within those constraints — enforced by smart contract, not by trust. Every transaction is logged on-chain with a human-readable memo. Owners can audit, pause, or revoke at any time. Deployed on Sepolia: 0x856737FA015CBFB3a9e87cE047CB5D5f46905DFB
