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

1. Create a wallets.js file.

   cd zkevm-contracts
   nano wallets.js

2. 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: ${wallet.privateKey}`);
       console.log(`mnemonic: "${wallet.mnemonic.phrase}"`);
   
       const keystoreJson = await wallet.encrypt("password");
       console.log(`keystore: $`{keystoreJson}``);
     }
   }
   
   main().catch((e) => {
     console.error(e);
     process.exit(1);
   });

3. Generate the wallets.

   node wallets.js | tee wallets.txt

Prepare environment variables

1. Edit the environment variables file.

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

2. 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

3. Send 1 Sepolia ETH to the deployment address wallet listed in wallets.txt.

Edit deployment configuration

1. Open the deploy-parameters.json file.

   cd zkevm-contracts/deployment/v2
   cp deploy_parameters.json.example deploy_parameters.json
   nano deploy_parameters.json

2. 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.
   • emergencyCouncilAddress: deployment address in wallets.txt.
   • deployerPvtKey: deployment private key in wallets.txt.

3. Open the create_rollup_parameters.json file.

   cd zkevm-contracts/deployment/v2
   cp create_rollup_parameters.json.example create_rollup_parameters.json
   vim create_rollup_parameters.json

4. Edit the following parameters to match the rollup parameters

   • trustedSequencer: trusted sequencer address in wallets.txt.
   • adminZkEVM: deployment address in wallets.txt.

Deploy & verify contracts

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

1. Install Hardhat:

   cd ..
   npm i @openzeppelin/hardhat-upgrades

2. Deploy Polygon zkEVM deployer

   npx hardhat run deployment/v2/2_deployPolygonZKEVMDeployer.ts --network sepolia

   You should see output that looks like this:

   #######################
   
   polygonZkEVMDeployer deployed on:  0xB1A5BA61fBAD71Ba52d70B769d6A994c01b40983

3. Verify deployer

   npx hardhat run deployment/v2/verifyzkEVMDeployer.js --network sepolia

   You should see ouput that looks like this:

   The contract 0xB1A5BA61fBAD71Ba52d70B769d6A994c01b40983 has already been verified.
   https://sepolia.etherscan.io/address/0xB1A5BA61fBAD71Ba52d70B769d6A994c01b40983#code

4. Prepare testnet

   npx hardhat run deployment/testnet/prepareTestnet.ts --network sepolia

   You should see output that looks like this:

   #######################
   
   pol deployed to: 0x2B2Ef864542EA38657221393B0A18215e5c3fc7e

   And now if you go to sepolia scan, you should also see that under your account, there's a new Pol Erc-20 token created with the balance of 19,900,000 tokens.
