Safety & honest status

Guardrails

Every payment is capped ($0.50 by default). A price above the cap is refused before anything is signed. Wallet key files are owner-only (0600).

Not done yet

  • No settled sale as a seller yet (needs a facilitator API key) — no independent payer or repeat counterparty.
  • x402 settlements aren’t tagged.
  • No named end user yet.

Open source
