Slippage

What is price slippage?

Slippage is defined as the move in the price of a security between the time you decided to transact in it and the time your order was in the market. When performing a trade on an AMM, the expected execution price may differ from the real execution price because the expected price depends on a past blockchain state, which may change between the transaction creation and its execution — e.g., due to front-running transactions.
