# frieNDA

> frieNDA puts an idea behind a real, attorney-drafted NDA. The signer reads the terms and pays a small amount (USDC over the x402 protocol, $0.25 by default). That payment is their legally binding electronic signature, and the idea opens. People and AI agents can both sign, over plain HTTP.

Key facts:
- Signing by payment: the x402 payment and the terms hash together form the signature. Email signing with a typed legal name is also supported.
- The sealed idea is never returned before signing. Public NDA metadata (title, terms, terms hash, price, network) is readable without paying.
- Agents must send X-Terms-Hash matching the current terms, or the server refuses with 409 TERMS_MISMATCH without charging.
- Networks: Base Sepolia (testnet, default) and Base mainnet. A mock mode simulates payments with identical responses.
- Governing law defaults to North Carolina, with arbitration in Charlotte, NC.
