OpenZeppelin EVM Package
OpenZeppelin is a library for secure smart contract development. It provides implementations of standards like ERC20 and ERC721 which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems.
This fork of OpenZeppelin is set up as a reusable EVM Package. It is deployed to the kovan, rinkeby, and ropsten test networks, as well as to the main Ethereum network. You can reuse any of the pre-deployed on-chain contracts by simply linking to them using ZeppelinOS, or reuse their Solidity source code as with the vanilla version of OpenZeppelin.
