Contract Templates

Ricardian Contract Templates

Each template generates a dual-format Ricardian Contract — human-readable legal text and machine-parsable JSON, linked by a SHA-256 hash. Choose a template, provide parameters via the API, and receive a verified contract.

Templates are structured frameworks for contract generation, not legal advice. Review generated contracts with qualified counsel before use.
