Slippage
In DeFi (Decentralized Finance)
Plain English
The difference between the price you expect when trading and the price you actually get. Like when you see an item for $100 but by the time you checkout it’s $105 because others bought it first. In crypto trading, slippage happens when the price moves while your transaction is being processed.
Technical
Price deviation between expected and executed trade price in AMM-based DEXs, caused by market movement during transaction processing or insufficient liquidity. Calculated as percentage difference from quoted price. Large trades relative to pool size cause higher slippage due to constant product formula. Users set maximum slippage tolerance - transactions revert if actual slippage exceeds this threshold.
