What the decoded transaction is telling you
The review panel reads back the exact bytes your wallet will sign. Four lines deserve your attention.
The decoder is separate from the code that builds the transaction, on purpose. It starts from the raw bytes, so a mistake in the builder would show here instead of hiding behind it.
The contract
This should be the venue you picked: a Uniswap router or the curve of that token. If it names anything else, stop.
The recipient
This should be your wallet. On routes that pay out ETH through a wrap, the first step pays the router and the next call unwraps to you; both lines are shown.
The minimum
This is the number that protects you, in the token's own units and in raw units. It should match the table.
The deadline
The transaction reverts after this time. The site sets 20 minutes.
Then compare with your wallet
Your wallet shows the same transaction in its own words. Reading both is the point: this site is not the last word on what you sign, your wallet is.
