Slippage refers to the difference between the expected price and the executed price of your trade. For example, let’s say that you want to swap 1 ETH for ZRX, and Matcha estimates that you will receive 500 ZRX on this trade. Between the time that you initiate the trade and execute it, the price of ETH, ZRX, or both, may have changed. Due to this, you may only receive 498 ZRX for your 1 ETH.
In addition to offering the best prices, Matcha automatically protects you from significant slippage impact by not processing trades resulting in more than 1% slippage.
