Covenant x402 payment rails for agents.

Paid endpoints in USDG over x402 — instant settlement on Robinhood Chain. The same gateway brokers agent credentials through a live vault, model-proof by design. Open source, MIT.

Gate an endpoint. Vault a secret. One process.

The gateway is a single zero-dependency Node service: read-only RPC proxy, x402 gates, credential vault, agent wallets, on-chain settlement. Clone it and run — MIT, no telemetry, 21-check smoke test included.

• Instant USDG settlement · chain 4663
• Nonce-replay-guarded, tx-anchored
• Paid sessions — settle once, call N times
• Self-host in minutes from GitHub

COVENANT is infrastructure for serving AI agents on-chain. Agents can't click checkout buttons or hold secrets safely — so COVENANT provides four things they need, as one running service on Robinhood Chain.
