Price impact and slippage are closely related concepts that describe how market conditions influence the final result of your swap, but they refer to different stages of the process.
Price impact is the immediate effect your swap has on the token's price inside the liquidity pool. Since pools use an automated market maker (AMM) model, every swap slightly changes the token ratio in that pool. The larger your swap is compared to the pool size, the greater the price impact.
Slippage refers to the difference between the price you see before confirming the transaction and the actual price at which the swap executes on-chain. Network delays, high volatility, or other users swapping at the same time can all increase slippage.
STON.fi shows both metrics before every swap, and you can adjust the slippage tolerance in settings to control acceptable deviation.
User responsibility
When you change slippage tolerance or other swap parameters yourself, you accept the associated risks. Raising these values above the defaults often leads to worse execution outcomes. STON.fi is not responsible for financial losses or unfavorable swap results caused by your own configuration choices, market conditions, volatility, or token-specific mechanics.
