@0xcert/ethereum-erc721-contracts

Smart contract implementation of the ERC-721 standard on the Ethereum blockchain.

The 0xcert Framework is a free and open-source JavaScript library that provides tools for building powerful decentralized applications. Please refer to the official documentation for more details.

This module is one of the bricks of the 0xcert Framework. It's written with TypeScript and it's actively maintained. The source code is available on GitHub where you can also find our issue tracker.

Package explanation

This package is based on our official ERC-721 implementation, but while the official implementation focuses on nice architecture for better readability and understanding for programmers, this package focuses mainly on the best gas efficiency. For this reason, we also have some opinionated implementations of, for example, how we handle token URIs.

Build

By default, the contracts in this package are built for Constantinople EVM. If you would like to use these smart contracts for Wanchain or other blockchains using EVM for a different version, you will need to rebuild them for the desired version.
