Deploy and Interact with a Solidity Contract

Deploy a Solidity contract​

Given Axon’s full compatibility with the EVM, contract deployment on Axon closely resembles the process on Ethereum. You can follow the Hardhat Getting Started for guidance. The only distinction is the network configuration.

This document assumes that you have followed the Axon quick start to run an Axon node.

When the project is created by npx hardhat, you just need to edit the hardhat.config.ts file as follows:

import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";

const config: HardhatUserConfig = {
  solidity: "0.8.19",
  networks: {
    axon: {
      url: "http://127.0.0.1:8000", // The RPC URL of Axon devnet
      // Axon devnet's accounts since the genesis block
      // See https://github.com/axonweb3/axon/blob/88c9a913/devtools/chain/specs/single_node/chain-spec.toml#L18C3-L21
      accounts: {
        mnemonic: "test test test test test test test test test test test junk",
        count: 10, // the number of accounts to derive
      },
    },
  },
};

export default config;

Now you can connect Hardhat to this Axon node, for example to run a deployment script against it, you simply need to run it using --network axon:

$ npx hardhat run scripts/deploy.ts --network axon

# Result
Lock with 0.001ETH and unlock timestamp 1694748964 deployed to 0xCf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9

Interact With the Deployed Contract​

Interacting with Axon contracts is the same as with Ethereum contracts. You can refer to https://docs.ethers.org for more details.
