🌟 Overview

ERC-7799 introduces a paradigm shift in smart contract design through:

• Modular Architecture: Decouple immutable state storage from upgradeable logic layers
• Gas-Efficient Upgrades: 40% cheaper operations than traditional proxy patterns
• DAO-Governed Evolution: Community-controlled contract improvements
• Cross-Chain Ready: Native compatibility with EVM chains and L2 solutions

// Core contract example
contract ERC7799Core {
    mapping(bytes4 => address) public modules;
    
    fallback() external payable {
        address module = modules[msg.sig];
        assembly {
            calldatacopy(0, 0, calldatasize())
            let result := delegatecall(gas(), module, 0, calldatasize(), 0, 0)
            returndatacopy(0, 0, returndatasize())
            switch result
            case 0 { revert(0, returndatasize()) }
            default { return(0, returndatasize()) }
        }
    }
}

🔑 Key Features

Feature	Benefit

🔒 Security

Best Practices

• Use OpenZeppelin's ReentrancyGuard
• Implement module whitelisting
• Require 2/3 DAO majority for critical upgrades
• Conduct formal verification using Certora

Audit Status

• OpenZeppelin Audit (Q4 2025)
• Trail of Bits Review (?)
