What it means
The maximum adverse price move you will accept between submitting a swap and it settling on-chain, expressed as a percentage.
Why it matters when you trade
On a DEX your transaction is public before it is final, and it executes against reserves that may change first. Tolerance is the guardrail: set it too tight and volatile swaps revert while you still pay gas; set it too wide and you have pre-authorised a sandwich attacker to extract exactly that much from you. Wide tolerance on a thin pool is the single most expensive default in retail DeFi.
Worked example
A 15% tolerance on a low-liquidity pool tells a bot precisely how much it can move price against you and still have your swap succeed.
See it on live markets
DexLadder runs slippage tolerance against live market and pool data, with simulated capital, so you can watch it act on an order instead of reading about it — no account, no wallet, nothing installed.
