What a Stale Swap Quote Means and How to Refresh It

A stale swap quote is an estimate that may no longer match the price your trade can get now. It can happen when other trades change a pool’s token balance or when a quote sits while you review it. Refreshing asks the interface for a new estimate, so you can compare the expected output before you approve.

A quote is not a reserved price. On a decentralised exchange, a trade changes the pool’s balances, which can move the price for the next trade. A route that uses several pools can also change while you wait. For the broader trade-off, read how quickswap compares with separate swaps. That choice is separate from whether a particular quote is still current.

What makes a swap quote stale?

A quote becomes stale when the conditions used to calculate it have changed. The interface estimates how much of the token you want to receive based on the available route and the pool prices it can see at that moment. New trades, a change in available liquidity, or a delay in fetching data can make that estimate outdated.

Look at the time between getting the quote and sending the transaction. If you leave the page open, switch networks, or take time to check the details, the pool may have changed. Some interfaces show a timer or quote expiry; others may simply update the estimate when you return. In either case, the displayed amount is an estimate until the transaction executes.

How do you refresh a swap quote?

Refresh the quote in the swap interface, then review the new figures before signing. If there is no refresh button, changing the amount slightly and changing it back may prompt a fresh quote; otherwise, reopen the swap screen. The interface should recalculate the route and expected output using the latest data it can access.

• Check that the input token and amount are still right.
• Compare the new expected output with the old one.
• Review the route, network fee and any displayed price impact.
• Read the slippage setting and transaction deadline before signing.

Slippage is the allowed difference between the quoted price and the price at execution. A tight limit can cause a transaction to fail if the price moves; a loose limit can let it complete at a worse price. Refreshing does not change that setting automatically on every interface, so check it yourself.

When should you wait instead of submitting?

Wait and get another quote if the expected output changes sharply or the route looks different from what you intended. A refreshed quote may still move before execution, especially if the pool is changing quickly. If the interface reports that the quote expired or the transaction failed, return to the swap screen and request a fresh estimate rather than retrying old transaction details.

Before signing, confirm the token, amount, network and minimum output shown in your wallet or swap interface. If those details do not match the trade you mean to make, stop and review the setup. For most readers, the useful habit is simple: refresh after a meaningful delay or price change, then check the new output and slippage limit before approving.
