The Number to Check Before a Cross-Chain Swap

The minimum received amount is the key number to check before a cross-chain swap: it is the least the route will accept for a completed transaction. The quote’s expected output is an estimate; the minimum reflects the slippage limit you set. It tells you the floor you are agreeing to before you send funds.

What does a cross-chain swap quote include?

A cross-chain swap takes an asset on one blockchain and delivers an asset on another, using a route that may combine a bridge and one or more token swaps. The quote estimates how much of the destination asset will arrive after the route’s exchange rates and charges are applied.

Costs can include swap fees, bridge or provider fees, and network fees for processing transactions on the source and destination chains. Some quotes show certain fees separately, and a destination network fee may come out of the delivered amount. For a fuller explanation of the route choice, see this Biswap guide to matching a bridge or swap to your destination; it explains the distinction behind the quote.

Check whether the displayed output is gross or net of fees, and whether you need to hold the source chain’s native token to pay its network fee. The wallet balance you need can be higher than the amount you plan to swap.

Why can the amount you receive change?

Prices and available liquidity can move between the quote and execution. A swap that trades against a liquidity pool may get a different rate if the trade is large relative to the pool; a route using multiple swaps can be affected at each step.

Slippage tolerance sets how much the execution can differ from the quoted rate before the transaction is rejected. A wider tolerance may allow a worse rate to go through, while a tighter one can cause a transaction to fail if prices move. It does not improve the rate or guarantee that the route will complete.

How should you compare two swap quotes?

Compare the amount you expect to receive in the destination token, the minimum received, and which fees are included. A larger destination amount may look better, but the minimum tells you how much downside you are accepting if the rate shifts before execution.

• Confirm the destination blockchain and token contract; similar token names can refer to different assets.
• Check whether source and destination network fees are included or charged separately.
• Compare the quoted output and minimum received, not just the advertised exchange rate.
• Review the slippage setting and estimated completion time before approving the transaction.

If one route offers more expected tokens but a much lower minimum, you are accepting more price movement risk for that potential gain. A failed transaction may still cost network fees, depending on where it fails and how the chain handles it.

Which amount should you use to decide?

Use the net destination amount to compare what each route is expected to deliver, then use minimum received to judge whether its downside is acceptable. If the difference between the expected output and minimum is too large for you, reduce the trade size, choose a route with different pricing, or wait for a fresh quote.

Before confirming, make sure you are comfortable with the minimum, have enough funds for any separate network charges, and have verified the destination token and chain. The quote is a snapshot; the minimum received is the useful limit for deciding whether that snapshot offers terms you can accept.
