Circle and IBM are both promoting the LCP protocol, which uses cryptographic fingerprints to leave an audit trail for AI trading. It doesn’t require on-chain execution, but it is compatible with blockchains—this design approach is indeed pragmatic: get the agents running first, then go from there.

CoinWorld News: The AI Agent Legal Context Protocol (LCP) from the American arbitration giant American Arbitration Association and Integra Ledger has been officially launched. It is designed to provide clear terms, consent, and dispute-path records for commercial transactions involving AI agents. The protocol allows software agents to carry out transactions without direct human review, helping enterprises form agreements, execute services, and transfer value with higher speed and efficiency. LCP uses cryptographic fingerprints of transaction-related terms to ensure the verifiability of transaction records. The protocol does not require a blockchain, but blockchain systems can be built on top of it. Founding contributors to LCP include Google, IBM, Circle, Wayfair, and others. The launch of this protocol marks the transition of AI agent payments from pilot projects to practical use.
