What happens after I send BTC?
  1. Broadcast: your wallet sends the exact BTC amount from the invoice directly to the ZeusAI owner wallet — no custodian.
  2. Mempool watch: the server polls mempool.space every ~30s until your transaction is seen and reaches at least 1 confirmation.
  3. Signed receipt: an Ed25519 receipt is appended to the autonomy chain the moment payment is observed.
  4. Delivery + license: your entitlement token, license and downloadable artefacts are generated and become available on this page and in your account.
  5. Refund contract: if delivery fails, the public refund guarantee applies — no email chase required.
