EVM Compatibility
QYN supports the Ethereum Virtual Machine. Deploy Solidity and use standard EVM tooling.
Overview
QYN is an EVM-compatible blockchain. The execution environment follows the Ethereum Virtual Machine specification, so Solidity smart contracts compile and run as on Ethereum. The chain uses a modern EVM revision (e.g. Cancun-style) and supports standard opcodes used by typical Solidity builds. For exact RPC methods, see RPC endpoints.
Solidity compatibility
Contracts written in Solidity (0.8.x and common earlier versions) work on QYN. Use the same compiler settings and libraries you would for Ethereum. No special pragmas or forks are required for standard contracts. Deploy with Hardhat, Foundry, or Remix as described in Build smart contracts.
Opcodes and precompiles
Standard EVM opcodes and common precompiles (e.g. ecrecover, keccak256, secp256k1) are supported. The chain is built for high throughput and low latency, so gas costs and limits may differ from Ethereum; check the latest chain parameters for exact values. Reentrancy and other EVM-level security considerations apply as on any EVM chain.
