📢 To depoly the contracts on mainnet, please contact our technical support that add your major contracts' addresses to the trusted list

The major contract of ERC721G is based on Azuki's ERC721A, thanks a lot.

Background

Since the circulation of NFT, there have been many incidents of theft. These incidents are mainly caused by private key theft and phishing attacks, and in the existing cases, it is difficult to recover once stolen. Most recovered cases also require a second offer from the stolen person, which is very costly. We propose a universal technical solution to be adapted to any ERC721 standard smart contract to help NFT holders guard their property security jointly.

About The Project

ERC721G

ERC721G is the world's first NFT anti-theft smart contract with three main features: "upgradeable," "scalable," and "secure." Dedicated to NFT asset protection, make Web3 a better place, and more people believe in it.

The first use case for ERC721G is the TurtlecaseGang NFT project, which proved the smart contract’s validity during several hacking events ( Premint websites hacking and Discord exploit incidents). For project details, visit https://opensea.io/collection/turtle-case-gang.

Big Brother

An offically implementation of TokenPatronus, know more about our whitepaper.

To cooperate with the ERC721G anti-theft contract to play an effective role, we have launched a set of risk control system: BigBrother. The BigBrother risk control system is an NFT anti-theft protection solution with multi-dimensional analysis and optimistic consensus voting mechanism. It helps NFT holders protect property safety through pre-protection, mid-blocking, and post-compensation. The system has three main parts: operation and maintenance strategy management, intelligent risk analysis, and real-time monitoring of changes.

Usage

Once installed, a basic example on how to inherit the ERC721G in your contract would look like the following.

pragma solidity ^0.8.15;

import "erc721g/contracts/ERC721G.sol";

contract TurtleCaseGang is ERC721G {
    constructor() ERC721G("TurtleCase Gang", "TCG") {}

    function mint(uint256 quantity) external payable {
        // `_mint`'s second argument now takes in a `quantity`, not a `tokenId`.
        _mint(msg.sender, quantity);
    }
}

Binding
