Deploying your contracts

The example is based on Hardhat framework

Prerequisite
Please follow Hardhat guide here​
Example: To create a Fixed-cap Asset
contracts/Token.sol
// SPDX-License-Identifier: MIT
​
pragma solidity 0.8.9;
​
import "@openzeppelin/contracts/token/ERC20/extensions/ERC20Capped.sol";
​
contract MyToken is ERC20Capped {
    constructor(uint256 _cap) ERC20("MyToken", "XXX") ERC20Capped(_cap) {
        ERC20._mint(msg.sender, _cap);
    }
}
​
Add network following network config to hardhat.config.ts
const config: HardhatUserConfig = {
    ...
    networks: {
        rei: {
            url: 'https://rei-rpc.moonrhythm.io',
            chainId: 55555,
        },
        reitest: {
            url: 'https://rei-testnet-rpc.moonrhythm.io',
            chainId: 55556,
        },
    ...
    solidity: {
        compilers: [
            {
                version: '0.8.9',
                settings: {
                    optimizer: {
                        enabled: true,
                        runs: 1000000,
                    },
                },
            },
        ],
    },
    ...
}
Compile your code using
npx hardhat compile
Deploy script
scripts/deploy.ts
import { ethers } from 'hardhat'
​
async function main() {
    let [owner] = await ethers.getSigners()
​
    const factory = await ethers.getContractFactory(
        'contracts/Token.sol'
    )
    const contract = await factory.deploy('100000000000') // capped
    await contract.deployed()
}
​
main()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })
​
Deploy to testnet
npx hardhat run --network reitest -- scritps/deploy.ts
Deploy to mainnet
npx hardhat run --network rei -- scritps/deploy.ts
Verify Contract
Now you will find your deployed contract on rei scan
Mainnet: https://reiscan.com/​
Testnet:  ​https://testnet.reiscan.com/​
1.Go to code tab and select Verify and Publish
2. Select Via flattened source code
3. Fill in the following
To get flattened code
npx hardhat flatten
