> For the complete documentation index, see [llms.txt](/ja/llms.txt). Dev Environments provide a complete set of tools for writing, testing, and deploying your smart contracts on Rootstock. Set your Solidity compiler and `evmVersion` to match [Development Prerequisites](/developers/requirements/). For opcode-level compatibility and Ethereum porting notes, use the [EVM Compatibility Explorer](https://rskj-evm-compatibility.rsk.co/). Some benefits of using a dev environment: * Streamlined Workflow: No need to cobble together tools from different sources – everything you need is in one place. * Efficiency: Dev environments automate repetitive tasks, saving you time and effort. * Error Reduction: Built-in features can help you catch bugs in your code before deployment. Here are supported dev environments for building and deploying smart contracts on Rootstock. - **[Hardhat](/dev-tools/dev-environments/hardhat/)**: Hardhat is an Ethereum development environment. Use it to write, test, and deploy smart contracts on Rootstock and other EVM-compatible chains. - **[Foundry](/dev-tools/dev-environments/foundry/)**: Foundry is a smart contract toolchain for Solidity. It manages dependencies, compiles, runs tests, deploys contracts, and talks to EVM-compatible chains through Forge. - **[Remix](/dev-tools/dev-environments/remix/)**: Remix is a browser IDE used to write, compile, deploy, and debug Solidity. Connect it to MetaMask to deploy to Rootstock Testnet and Mainnet.
