Minimum received limits the risk in cross-chain swaps

A minimum-received threshold sets the least output a cross-chain swap can deliver, but its protection depends on where the route enforces it and what happens on failure.

Minimum received limits the risk in cross-chain swaps

A minimum-received setting limits how little a cross-chain swap can deliver before the route stops or follows its failure process. Cross-chain routes may involve separate steps on different networks, so the threshold’s value depends on where it is checked.

  • Expected output: the amount shown in the quote.
  • Minimum output: the lowest amount the route accepts at the stage it checks.
  • Failure handling: what the route does if it cannot meet that floor.

How does minimum received protect a swap?

The setting turns a quote into a limit. If the checked output falls below the minimum, the relevant swap step should fail instead of completing at a worse rate. This can guard against price movement while a transaction waits or while a route executes.

The minimum is often calculated from the quoted output and a slippage tolerance. Price impact describes how the trade itself affects available liquidity; slippage describes how execution differs from the quote. A threshold does not freeze the price or promise that the swap will complete.

Where does the limit apply in a cross-chain swap?

That depends on the route. A cross-chain swap may combine a swap on the source network with a bridge or relay step and a further swap on the destination network. A displayed minimum may apply to one step or to the final amount delivered, so check what the quote labels as “minimum received.”

If a transaction is pending, its status alone does not show whether the output limit will be met. For the separate question of how to handle a pending quickswap, see the linked guide. The route’s own status and failure instructions determine what to do next.

What should you check before signing?

Confirm the output token, minimum amount, and network where that amount is measured. Then check the route’s stated failure handling. Some routes may leave an earlier step completed even if a later step cannot finish, so a failed destination step does not necessarily mean every earlier action was undone.

A very tight minimum can cause a swap to fail after a small price move. A loose one permits a larger shortfall. Set the floor at an amount you would accept, and treat it as a bound on execution, not insurance against every cross-chain failure.
