Every agentic payment bound to the terms that govern it.
Legal Context Protocol anchors every Stellar transaction to the exact legal terms — using only native CAP-67 primitives. AAA-enforceable, FRE 902 self-authenticating, in a single on-chain transaction.
The seller's LCP discovery document
The buyer's agent fetches /.well-known/legal-context-docusign.json from the seller. The document publishes the terms URL, SHA-256 content hash (the ATR hash), and the dispute-resolution clause.

}The 402 payment challenge
The seller responds with HTTP 402. The payment destination is a CAP-67 muxed M-address whose mux_id is derived from the advertised ATR hash. Paying to this address cryptographically commits to those exact terms.

}]
}The agents negotiate, bind, and settle
Buyer verifies ATR binding, signs a Soroban transfer to the muxed destination, and submits to Stellar mainnet. Terms and payment bind in one transaction.
Same eight bytes, two places, one commitment
Terms, payment, and enforcement — cryptographically bound to one Stellar transaction. Evidence bundle ready for AAA filing.
