## EVM-Compatible Tools

Continue utilizing familiar Ethereum development tools such as Web3.js, Truffle, Ethers, Hardhat, and Foundry to build on Hedera using the [JSON-RPC Relay](/docs/core-concepts/smart-contracts/json-rpc-relay.md). As an Ethereum developer, your workflow does not have to change.
