Gas Limit Manipulation Possible by 1/64 Rule

What it detects​

Prior to EIP-150, only a fraction of gas was forwarded when calling another contract. Using send or transfer forwards exactly 2300 gas, which can be exploited to block logic if more gas is needed. The detector highlights such calls that rely on limited gas forwarding.

Typical symptoms​

  • Use of transfer to send ether
  • Contract assumes recipient code cannot execute complex logic

Solidity snippet (v0.8.25)​

pragma solidity ^0.8.25;

contract GasTrap {
    function pay(address payable to) external {
        // Only 2300 gas forwarded, recipient may revert
        to.transfer(1 ether);
    }
}

Why it matters on EVM​

Attackers can manipulate gas costs or deliberately revert to lock funds or disrupt execution when calls rely on the 2300 gas stipend.
