## Commercial License (Covenant module)

The covenant module — including SilverScript contract sources, escrow
logic, payment channel implementations, and agent negotiation protocols
under `vida/plugins/covenant/` — is licensed under a commercial,
royalty-bearing model. This module is NOT covered by the MIT grant above.

### What this means

- **Free for non-commercial use, evaluation, and testing.** You may run,
  modify, and experiment with covenant code locally, on testnet, and in
  personal projects at no cost.
- **Commercial deployment requires a license.** If you use Vida's covenant
  module in a revenue-generating product, service, or agent fleet (including
  hosted or embedded deployments), you must obtain a paid license.
- **Small-scale / low-revenue exemption:** Projects under $10,000 annual
  revenue may request a free commercial license.

### How to obtain a license

Contact: `vida-license@` (domain TBD) or open an issue on GitHub titled
"Commercial License Inquiry." Include your use case, expected volume,
and deployment details. We respond within 5 business days.

### Why commercial?

Covenants are the moat — they're the hard on-chain limits that make agent
delegation cryptographically enforceable. The R&D and toolchain investment
(including SilverScript, Kaspa SDK integration, and Toccata mainnet
readiness) is significant. A commercial covenant license ensures ongoing
maintenance while keeping the core wallet, TAO plugin, agent layer, and
CLI tools MIT-licensed and free forever.
