An open-source adversarial test suite that verifies whether x402 payment facilitators actually honor their protocol invariants.

Why it surfaced

Ward runs eight checks against a real self-hosted facilitator—not a mock—including retry safety, concurrent double-settlement, allowlist enforcement, and Algorand-specific authorization risks. It also offers a hosted $1 verification run that returns reproducible evidence such as request/response pairs and on-chain transaction IDs.
