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