Cross-chain swap quote changed? Check the route and minimum

A cross-chain swap quote can change when market prices, network costs or available routes shift between checks. Before approving, compare the minimum amount you will receive, the route shown and any expiry time; the headline estimate alone does not tell you what the transaction guarantees.

Why did my cross-chain swap quote change?

A quote is a calculation for a particular trade at a particular moment. The swap interface combines the tokens and amounts you selected with the prices, liquidity, fees and route information available to it when it requests the quote. If one of those inputs changes, a refreshed quote can show a different output.

Cross-chain routes may involve a swap on the source network, a transfer between networks and a swap on the destination network. Each step can have its own cost or execution risk, so two routes for the same token pair can show different receive amounts or estimated completion times. For a fuller explanation of how to weigh route choices, see fermi swap.

Also check that the refreshed quote still matches your intended source and destination networks, token contracts and trade size. A matching token ticker does not, by itself, establish that two tokens are the same asset on different networks.

Which number on the quote should I trust?

Use the minimum receive amount as your decision point, and treat the estimated amount as an estimate. Quote interfaces may show both: the estimate describes the expected output, while the minimum reflects the lower amount permitted under the quoted slippage setting. A lower minimum gives the trade more room to execute after prices move, but also allows you to receive less.

Compare these fields before you approve:

• You send: the token, network and amount being spent.
• You receive: the destination token and estimated output.
• Minimum received: the lower bound shown for the trade under its current settings.
• Route and costs: the networks and swap steps involved, plus any displayed network or service fees.

Network fees are not always paid in the token being swapped. Check which wallet balance will cover them, and whether the interface shows a separate fee or subtracts a cost from the amount received. If the quote shows a completion estimate, read it as a forecast rather than a guaranteed delivery time.

What should I check before approving?

Refresh the quote and make sure its minimum output still works for you. Confirm the token addresses or network labels in the wallet transaction match the route in the swap interface; an approval authorizes a token contract to use tokens, while the swap itself is a separate transaction.

If the route has changed, compare the new minimum received and total costs with the original quote, then decide whether to proceed or wait. Do not approve a transaction whose destination token, network or spending amount differs from what you selected. If the quote has an expiry, check it again before signing.

After approval, follow the transaction status in the interface or wallet. Cross-chain transfers can require confirmation on the source network before the destination step begins, so the next useful check is whether the source transaction has completed and the route has advanced.
