Pay in from any venue

A buyer on any venue pays the way that venue already pays. Its own bridge moves the money to its own address on a network the door settles, or the money stays where it is; then each call is paid with x402. No key, no account, no gas money.

Never

  • a bridge delivery to our vault (it is sent by the bridge's wallet and names no buyer: nothing could credit or record it to the buyer)
  • a requirement of ours before the first paid call (a key, a registration, an account, a spec): x402 pays without them
  • a signature, deposit or payment by Taifoon: the buyer signs its own bridge deposit and its own x402 authorization
  • a new top-up entry point (TOPUP-UNDER-VAULT §1.3): the money lands per call as the vault form x402
