What Minimum Received Means on a Crypto Swap

Minimum received is the smallest amount of tokens a swap will deliver before the transaction is rejected. The swap screen starts with a quote, applies a tolerance for price movement, then passes the resulting minimum to the contract that executes the trade.

What does minimum received mean on a swap?

Minimum received turns a changing market quote into a condition the transaction must meet. First, the app estimates how many tokens the swap should return from the amount and route you selected. It then calculates a floor from your slippage tolerance. The router contract checks the actual output against that floor when the transaction runs. If the output is lower, the transaction reverts instead of completing the swap.

Think of the floor as a limit on what you are willing to accept: it does not promise the quoted amount, but it defines when the trade should stop. A route through several token pools can produce a different result from a direct route because each pool contributes its own price and fees. For a fuller explanation of how chart reading and execution fit together, see Poocoin’s guide to charts, tracking and swaps. The quote and the minimum are estimates and rules for that particular transaction, not guarantees about a token’s value.

How does slippage tolerance affect the minimum?

Slippage tolerance determines how far the output may fall below the quote before the router rejects the trade. A larger tolerance lowers the minimum received, giving the transaction more room to execute after the market moves. A smaller tolerance raises the floor, protecting the output while making a revert more likely if the quote changes before execution.

This setting is separate from price impact. Price impact is the effect the swap itself has on the pool’s price, often because the trade is large relative to available liquidity. Slippage is the difference between the expected result and the result available when the transaction executes. A swap can have high price impact even if the market stays still; it can also face slippage if other trades change the pool before yours is processed.

When a swap reverts, check the quoted route, the token amount and the market movement before changing the tolerance. Raising it may allow the trade to complete at a worse rate. It does not improve the quote or remove the price impact.

What should an occasional swapper check?

Use the minimum received as the practical decision point: before confirming, make sure the floor is an output you would accept. The better choice for most occasional swappers is to keep the tolerance tight enough to reject a meaningfully worse fill, then adjust only when a clear execution issue justifies it.

• Read the expected output and minimum received together; the gap between them is the allowance for movement.
• Check the route and pool liquidity when the quote looks unexpectedly poor, since a larger trade can move the price more.
• If the transaction repeatedly reverts, inspect whether the market is moving or the route is thin before increasing tolerance.
• Review the token, network and transaction details before signing; a minimum-output check does not establish that a token or contract is trustworthy.

For a one-off trade, the setting is a boundary, not a prediction. Keep it at a level that makes the outcome acceptable, and treat a revert as information to review the trade rather than an automatic reason to loosen the limit.
