Continue with the Third Step of this Deployment-Guide where you create wallets and deploy contracts.

Deploying Contracts

Clone the contracts from our GitHub repository:

git clone <https://github.com/0xPolygonHermez/zkevm-contracts.git>
cd zkevm-contracts
npm i

Create Wallets

Next, create a wallets.js file with the following content:

const ethers = require("ethers");

async function main() {
  const arrayNames = [
    "## Deployment Address",
    "\\n\\n## Trusted sequencer",
    "\\n\\n## Trusted aggregator",
  ];
  for (let i = 0; i < arrayNames.length; i++) {
    const wallet = ethers.Wallet.createRandom();
    console.log(arrayNames[i]);
    console.log(`Address: ${wallet.address}`);
    console.log(`PrvKey: ${wallet._signingKey().privateKey}`);
    console.log(`mnemonic: "${wallet._mnemonic().phrase}"`);

    const keystoreJson = await wallet.encrypt("password");
    console.log(`keystore: ${keystoreJson}`);
  }
}

main().catch((e) => {
  console.error(e);
  process.exit(1);
});

Don't forget to generate the wallets using below command:

node wallets.js | tee wallets.txt

Prepare Deploy Configuration

Edit the environment variables:

cp .env.example .env        # copies .env.example file into .env
nano .env                   # opens .env file for editing

Set these variables:

MNEMONIC="..."              # from wallets.txt Deployment Address mnemonic
INFURA_PROJECT_ID="..."     # your Infura project ID
ETHERSCAN_API_KEY="..."     # your Etherscan API key

Next, open the deploy_parameters.json file in nano editor:

cd deployment
cp deploy_parameters.json.example deploy_parameters.json
nano deploy_parameters.json

Fill in the relevant details in the deploy_parameters.json:

{
  "realVerifier": true,
  "trustedSequencerURL": "<http://X.X.X.X:8545>", // your public IP
  "networkName": "zkevm",
  "version": "0.0.1",
  "trustedSequencer": "", // from wallets.txt Trusted sequencer
  "chainID": 42069, // put your preferred id
  "trustedAggregator": "", // from wallets.txt aggregator sequencer
  "trustedAggregatorTimeout": 604799,
  "pendingStateTimeout": 604799,
  "forkID": 4,
  "admin": "", // from wallets.txt Deployment Address
  "zkEVMOwner": "", // from wallets.txt Deployment Address
  "timelockAddress": "", // from wallets.txt Deployment Address
  "minDelayTimelock": 1,
  "salt": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "initialZkEVMDeployerOwner": "", // from wallets.txt Deployment Address
  "maticTokenAddress": "", // put an existing contract address or leave it empty to auto-deploy a new contract
  "zkEVMDeployerAddress": "", // put an existing contract address or leave it empty to auto-deploy a new contract
  "deployerPvtKey": "",
  "maxFeePerGas": "",
  "maxPriorityFeePerGas": "",
  "multiplierGas": ""
}

:::caution Get some GöETH

You will need to send 15 GöETH to the Deployment address listed in wallets.txt.

:::

Adjust the gasPrice according to the network status. For Goerli, you can check it with the following command, where you insert your Etherscan API key:

ETHERSCAN_API_KEY="" echo "$(($(printf "%d\\n" $(curl -s "<https://api-goerli.etherscan.io/api?module=proxy&action=eth_gasPrice&apikey=$ETHERSCAN_API_KEY>" | jq -r .result))/1000000000)) Gwei"

Edit ~/zkevm/zkevm-contracts/deployment/helpers/deployment-helpers.js to adjust the gasPrice according to network status. It is recommended to add 50 Gwei to the current gasPrice to ensure transactions are processed quickly.

const gasPriceKeylessDeployment = "50"; // 50 Gwei

Deploy Contracts

npm run deploy:deployer:ZkEVM:goerli
npm run verify:deployer:ZkEVM:goerli
npm run deploy:testnet:ZkEVM:goerli
npm run verify:ZkEVM:goerli

The previous scripts will auto-deploy the MATIC token contract and the zkEVMDeployer contract if required.

You will see in the logs the verification of each smart contract deployed, but you can check it on etherscan too.
