Slippage Parameter Missing or Ineffective

What it detects​

The detector checks for exchange functions that fail to bound price movement with a slippage parameter. Without this guard, trades can execute at unfavorable rates if the market shifts.

Typical symptoms​

  • Swap functions that accept any output amount
  • No check against the minimum received tokens

Solidity snippet (v0.8.25)​

pragma solidity ^0.8.25;

contract Swap {
    function trade(uint256 amountIn) external {
        // No slippage check on the output amount
        // tokensOut = getPrice(amountIn);
    }
}

Why it matters on EVM​

Ineffective slippage protection exposes users to major losses from price manipulation during transaction execution.
