Datamine Network has successfully upgraded its entire smart contract unit testing suite to the newly released Hardhat v3. This migration ensures the ecosystem's testing environment matches the absolute latest standards in Web3 development. ## Upgrading to Hardhat v3 and Ethers v6 Migrating to Hardhat v3 required overcoming integration complexities with the IERC1820 token registry standard. To resolve this, the development team converted the legacy IERC1820 npm package into a compatible, custom Hardhat v3 plugin. Alongside this upgrade, the repository has been fully transitioned to Ethers v6, allowing the test suite to leverage modern smart contract interaction libraries. ## Modernizing the Development Stack The update achieved a perfect Modernization Score of 100/100, reflecting the adoption of modern JavaScript and TypeScript paradigms. Key enhancements to the codebase include: * **ES Modules (ESM):** Complete migration to native ES Modules (`"type": "module"`), deprecating legacy CommonJS formats. * **Flat Configuration:** Adoption of ESLint v9 and its new flat configuration standard (`eslint.config.mjs`). * **Strict TypeScript:** Utilization of TypeScript v5.9 with strict type-safety rules and modern compiler targets (ES2022/ESNext). These structural improvements ensure that Datamine's smart contracts—which govern the ecosystem's decentralized monetary policies and liquidity games—remain robust, secure, and easily maintainable by the developer community.
