Create wallets

Set up wallet contracts¶

Clone the wallet contracts from the zkevm-contracts repository and install the npm libraries.

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

Create wallets¶

Create a wallets.js file.
```
cd ~/zkevm-contracts
nano wallets.js
```

Copy/paste the JavaScript code below.

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);
});

Generate the wallets.
```
node wallets.js | tee wallets.txt
```

Prepare environment variables¶

Edit the environment variables file.

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

Set the following variables.

MNEMONIC="..."            # from wallets.txt Deployment Address mnemonic
INFURA_API_KEY="..."      # your API Key from Infura account
ETHERSCAN_API_KEY="..."   # your Etherscan API key

Send 0.5 Sepolia ETH to the deployment address wallet listed in wallets.txt.

Edit deployment configuration¶

Open the deploy-parameters.json file.

cd ~/zkevm-contracts/deployment
cp deploy_parameters.json.example deploy_parameters.json
nano deploy_parameters.json

Edit the following parameters to match the generated wallet parameters.
- trustedSequencer: trusted sequencer address in wallets.txt.
- trustedAggregator: trusted aggregated address in wallets.txt.
- admin: deployment address in wallets.txt.
- zkEVMOwner: deployment address in wallets.txt.
- timelockAddress: deployment address in wallets.txt.
- initialZkEVMDeployerAddress: deployment address in wallets.txt.
- zkEVMDeployerAddress: deployment address in wallets.txt.

Deploy contracts¶

cd back to zkevm-contract root directory and run the deployment scripts.

Tip

It might be helpful to run these one at a time.

cd ..
npm i @openzeppelin/hardhat-upgrades
npm run deploy:deployer:ZkEVM:goerli
npm run verify:deployer:ZkEVM:goerli
npm run prepare:testnet:ZkEVM:goerli && npm run deploy:ZkEVM:test:goerli
npm run verify:ZkEVM:goerli

You should see output that looks something like this at the start each time:

> @0xpolygonhermez/zkevm-contracts@3.0.0 deploy:deployer:ZkEVM:goerli
> npx hardhat run deployment/2_deployPolygonZKEVMDeployer.js --network goerli

#######################

polygonZkEVMDeployer deployed on:  0x8c4e69A65f84D5Ee0d83095916706Be74C133571

Info

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

Check the deployment was successful on Etherscan.
