What if…
What is slippage?
Slippage is how much the price can move while the swap runs. 1% is the usual safe setting.
Why prices move
A route takes time, and pools change price every time someone trades. Slippage is the most the price may move against you before the swap stops instead of going ahead.
Choosing a setting
- 1% suits most swaps.
- A very small pool, or a token with high volatility, may need more.
- A lower setting protects the price but fails more often on busy markets.
If the limit is hit
The hop does not go ahead at the worse price. The route stops and the amount goes back to your refund address, minus the network cost already paid.
