Example

User authorizes payment of invoice INV-1042: 1,000 USDC, named network, named wallet, registered counterparty. Recipient from a directory. USDC contract from a pinned registry. Fees capped separately.

For six decimals the raw amount is 1000000000. Decimals come from trusted metadata, not from a ticker in the email.

1. Intent Authority fixes the details and the one-shot business key.
2. Proposer prepares a transfer. The signed proposal carries the operation bytes.
3. Semantic Verifier decodes and checks recipient, contract, amount, network, purpose.
4. Safety Verifier checks budget, duplicate invoice, simulation. An unlimited approve is DENY.
5. Gate checks attestations, freshness, digest, and claims INV-1042.
6. Adapter submits. Receipt Verifier waits for the required finality and the actual credit.

If the address changes after step 4, the digest changes and the signatures stop matching. If the user confirmed a wrong address in the intent, VAP will not invent a “real” one.
