Set a Minimum Before You Make a Cross-Chain Swap

Before you confirm a cross-chain swap, set the lowest amount of the destination token you are willing to receive. The quote is an estimate; the minimum output is your limit if prices or available liquidity shift while the swap is underway. That limit helps you decide whether a worse rate is still acceptable.

A swap across blockchains may rely on liquidity pools, where traders’ tokens are held for exchanges, and may take more than one step. Each step can affect the amount that arrives. A thor swap is one example of a cross-chain route; the fuller explanation shows how assets move between chains. For setting a minimum, focus on the amount you will receive at the end.

What does slippage mean in a cross-chain swap?

Slippage is the difference between the amount shown in a quote and the amount the swap can deliver. It can happen when the token price changes or when a trade uses up some of the available pool liquidity. A large trade compared with the pool can move the price more than a small one.

Cross-chain swaps can add time and steps between the quote and delivery. The source-chain transaction may confirm first, while a later part of the route is still waiting. During that gap, prices and pool conditions can change. Network fees and route fees also affect what reaches your wallet, though they are not slippage themselves.

How do I choose a minimum output?

Start with the quoted amount after any fees the interface has already included. Then ask how much less you would still accept. If a quote shows 100 destination tokens, for example, a minimum of 98 means you accept receiving as little as 98. The right limit depends on your own trade; there is no setting that suits every swap.

Use this quick check before confirming:

• Check that the destination token and network are correct.
• Read the estimated amount and the minimum output in the same units.
• Pick a minimum based on the least you would accept, not on a guess about where the price will go.
• Review the fees and route details, since they affect the final amount.

What happens if the swap falls below my minimum?

If the route supports a minimum-output condition, a result below that limit should cause the swap to fail or stop instead of completing at a worse amount. The exact handling depends on the service and route. A failed swap can still involve network fees, so check the interface’s terms before signing.

A very tight minimum may reject a swap after a small price move. A very loose one may let it complete at a rate you would regret. For most readers, the useful setting is the lowest amount they can genuinely accept. If the quote only works with almost no room for change, waiting for a steadier market or choosing a smaller trade may be the clearer choice.
