Deploy a contract

Fenryx's EVM is standard — anything that works on Ethereum mainnet will deploy unchanged. The interesting part is calling native modules from inside Solidity.

1. Toolchain​

npm i -g hardhat
# or
cargo install foundry --locked

hardhat.config.ts:

networks: {
  fenryx: {
    url: 'https://v2.evm.fenryx.io',
    chainId: 7373,
    accounts: [process.env.PRIVKEY!],
  },
}

2. Deploy​

npx hardhat run scripts/deploy.ts --network fenryx

The transaction will appear in the explorer within ~1 block.

3. Call native modules​

import "@fenryxlabs/contracts/IFenryx.sol";

contract MyVault {
    IFenryx constant fenryx = IFenryx(0x0000000000000000000000000000000000007373);

    function stake(address validator, uint256 amount) external {
        require(fenryx.didLevel(msg.sender) >= 2, "L2 DID required");
        fenryx.stake(validator, amount);
    }
}

4. Verify​

The ABI Decoder page can decode an eth_call blob against your ABI JSON — useful while iterating on a function selector.
