Staking Protocol Patterns

This skill provides comprehensive knowledge for auditing DeFi staking and reward distribution mechanisms.

Common Staking Patterns

1. Simple Staking (No Rewards)

contract SimpleStaking {
    mapping(address => uint256) public staked;

    function stake(uint256 amount) external {
        token.transferFrom(msg.sender, address(this), amount);
        staked[msg.sender] += amount;
    }
