Slippage in Decentralized Exchanges
Slippage in decentralized exchanges refers to the difference between the expected price of a trade and the price at which the trade is actually executed. In automated market makers, liquidity is provided by pools of assets rather than a traditional order book.
When a trader initiates a swap, they consume a portion of the pool, which shifts the ratio of the assets and moves the price along a mathematical curve. If the trade size is large relative to the available liquidity, the price impact becomes significant, resulting in a worse execution price than originally anticipated.
This phenomenon is a fundamental aspect of market microstructure in decentralized finance. It serves as a cost that reflects the depth of the liquidity pool and the efficiency of the underlying pricing algorithm.
Traders often set a maximum slippage tolerance to prevent their orders from being filled at unfavorable prices during periods of high volatility. Understanding slippage is crucial for managing transaction costs and assessing the viability of executing large orders on-chain.
