Build Smart Contracts on QYN
Deploy and interact with Solidity contracts on the QYN blockchain. Same tooling as Ethereum.
EVM compatibility
QYN is EVM compatible. Contracts written in Solidity compile and run on QYN without code changes. Use Hardhat, Foundry, Remix, or any EVM toolchain. Point your config to RPC https://rpc.getquyn.com and Chain ID 7779 for testnet. See EVM compatibility for supported opcodes and behaviour.
Deploying
If you require testnet balances for development, follow the instructions on the testnet page. In Hardhat or Foundry, set the network to QYN testnet (RPC URL and chain ID above). Run your deploy script; the transaction will be sent to the network and the contract will be deployed. You can verify the transaction and contract address on the explorer.
Interacting
Call contract methods via your dApp (e.g. ethers.js, viem) using the same RPC. Users can interact through any Web3-compatible client once the QYN network is added.
