Read a DEX Swap Quote Before You Trade
A DEX quote estimates your output, route and fees before a swap; learn which figures to compare, why they move and how to set a sensible minimum.

The quoted output is the first number to read in a DEX swap quote. It estimates how many destination tokens your input could receive through the displayed route at the time of the quote. It matters because the estimate can change before execution, while the minimum output defines the least you have agreed to accept.
What does a DEX swap quote show?
A quote previews a trade between two tokens: what you put in, what you may receive, and the path the trade takes through available liquidity. A direct route uses one pool; a multi-hop route trades through an intermediate token, which can find better prices but adds another exchange step.
Look at the output amount alongside the route and the fees. The quoted rate is usually the output divided by the input, but it does not tell the whole story: pool fees and the effect of your trade on available liquidity can make the rate worse than a simple market price comparison suggests.
For a chain-specific walkthrough of setup and common fee mistakes, the fuller quickswap guide covers details that a quote alone cannot show. When you compare routes, use the same input amount and check whether the displayed output already accounts for the fees the interface lists.
Why can the quoted output change?
The quote is an estimate based on liquidity and prices when it is requested; it is not a guaranteed execution price. If other trades move the pool before your transaction is processed, or your own trade is large relative to the pool, the final output can differ.
Slippage is that difference between the expected and executed price. A DEX interface may let you set a slippage tolerance, which limits how far the price can move before the transaction fails. A tighter limit can protect you from accepting a worse rate, but it can also make a trade fail when prices move quickly.
Which figures should you compare before swapping?
Compare the minimum output, the route, and the total cost to complete the transaction. The minimum output is the threshold the trade must meet; gas is the network fee for processing it and may be shown separately from the token amount received.
Quoted output: the estimated amount of the token you receive.
Minimum output: the lowest amount the transaction will accept under the current settings.
Route: the pool or sequence of pools used to make the trade.
Fees and gas: the trading fees reflected in the route and the network cost, which may be charged separately.
For most beginners, the better choice is the route with the strongest minimum output after fees, provided you understand its path and can cover the gas. A headline rate can look attractive while hiding an extra hop or a higher network cost.
Before you confirm, check that the token and network are the ones you intend to use, then review the minimum output and gas estimate in your wallet. If the quote changes or the minimum looks too low, pause and request a fresh quote rather than approving a trade you no longer understand.
