QYN is EVM compatible. Use the same tools and languages you already know—Solidity, Hardhat, Foundry, and modern Web3 clients—and deploy to a fast, low-cost chain.

EVM compatibility

QYN supports the Ethereum Virtual Machine (EVM). Smart contracts written in Solidity work on QYN without changes. You can use Hardhat, Foundry, Remix, or any EVM toolchain. The chain supports standard JSON-RPC methods, so wallets, indexers, and dApps can integrate easily. For a full list of supported methods and opcodes, see EVM compatibility and RPC endpoints.
