What is slippage in a Stock Token swap?
How price movement, pool depth and minimum output determine whether an onchain order fills or reverts.The simple definition
Slippage is the difference between the quoted output and the minimum output you are willing to accept. A 0.5% setting tells the router to revert if the delivered amount falls below 99.5% of the fresh quote.
Why it grows
Larger orders move farther through a pool. Thin liquidity, changing prices and extended-hours trading can widen the difference between the first quote and wallet confirmation.
Lower is not always better
A very tight setting gives stronger price protection but can cause more failed transactions when a market is moving. A wider setting may fill more easily but accepts a worse minimum. HoodFlow limits the available range and shows the output floor before submission.
What a revert means
A slippage revert means the protection worked: the router did not accept an output below your floor. Request a new quote, reassess the amount and never treat repeated reverts as a reason to sign a blind transaction.
