AAA launches a legal standard for transactions between AI agents: LCP — a new layer of trust
The American Arbitration Association (AAA), together with Integra Ledger and a broad coalition of technology giants, has introduced the Legal Context Protocol (LCP) — an open standard designed to regulate the legal aspects of transactions conducted by artificial intelligence. This is not just another protocol, but a fundamental shift in how we will trust autonomous systems.
AI agents are transforming the future of commerce, helping people and organizations form agreements, execute services, and move value with greater speed and efficiency. But participants need to trust that transactions are understandable, accountable, and resolvable when disputes…

LCP acts as a "legal layer" that is placed on top of existing technical solutions for payments (e.g., x402 and Machine Payments Protocol), identification and coordination of agents (Trusted Agent Protocol, A2A, Verifiable Intent). If these systems are responsible for the "how" of a transaction, LCP defines the "terms," which law applies, and how disputes are resolved. This is critically important in a world where counterparties are lines of code, not people with passports.
The key advantage of LCP is its universality. The standard does not require a blockchain, intermediaries, or special infrastructure. Any organization with a web server can implement it. The specification, reference implementation, and integration examples have already been published under the Apache 2.0 license. Project governance is planned to be transferred to a neutral foundation in the future, ensuring its independence.
The list of founding participants is also impressive: Google, IBM, Circle, Wayfair, Stellar Development Foundation, Ava Labs, Cardano, Hedera, Aptos Foundation, and others. This consensus between Web2 giants and Web3 leaders speaks to the maturity of the problem and the market's readiness for standardization.
AAA President Bridget McCormack rightly notes that the legal infrastructure of e-commerce, created 20 years ago, is simply not designed for scenarios where decisions are made by AI. David Fisher of Integra Ledger calls LCP a "necessary legal layer," while Hedera co-founder Mance Harmon emphasizes: as agent autonomy grows, we need a clear answer to the question "what to do if something goes wrong."
AAA forecasts confirm the relevance of the initiative: by 2028, 90% of all B2B purchases will be made by AI agents, and the volume of such transactions will exceed $15 trillion. Without a legal foundation, this market would remain a high-risk zone.
Expert opinion: LCP is precisely the "bridge" that was missing for the mass adoption of AI agents in the corporate sector. Technically, autonomous transactions are possible today, but without a clear legal framework and dispute resolution mechanism, no serious business will risk entrusting large transactions to AI. The AAA initiative could be the catalyst that transforms AI agents from an experimental tool into a standard of business practice.
