Run just before signing a transfer built from a request like "send 5 USDC to X", or a swap built for "swap 1 USDC for JUP". Confirms it moves exactly that token, amount and recipient, nothing more, or that the swap sells exactly that amount and pays the bought token back to you. Catches made-up amounts, wrong decimals, hidden steps and swaps that pay someone else.
