Prepare the selected bridge route as ordered unsigned transactions: an exact-amount ERC-20 approval when needed (after an approval to 0 for tokens like Ethereum USDT), then the bridge transaction. Pass the minTargetAmount and maxNativeFee the user accepted; if the fresh quote delivers less or charges more native fee, it returns 409 with quote { adapter, estimatedTargetAmount, minTargetAmount, nativeFee } and no actions. Send the actions before expiresAt.
