Origin DeFi’s open-source project, OTokens, encompasses Origin Dollar (OUSD) and Origin Ether (OETH) smart contracts, providing a robust framework for decentralized finance on Ethereum. Utilizing Hardhat for seamless Ethereum Virtual Machine (EVM) management, the project supports Node.js versions 16 to 18 and recommends the popular Metamask web3 wallet. Developers can clone the repository and leverage Hardhat’s forked mode to mimic the mainnet environment, enhancing reliability in development. The `contracts` directory serves as the project’s hub, facilitating interaction with third-party protocols like Uniswap and Sushiswap. With comprehensive smoke and fork testing scripts, contributors are encouraged to participate via Origin Protocol’s Discord community, reflecting OTokens’ commitment to continuous improvement and community engagement in the DeFi space.
