Create wallets
Clone the contracts¶
Clone the contracts from our github repository:
cd ~
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:
cd ~/zkevm-contracts
vim wallets.js
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 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:
cd ~/zkevm-contracts
cp .env.example .env
vim .env
Set these variables within your .env file:
MNEMONIC="..." # from wallets.txt Deployment Address mnemonic
INFURA_PROJECT_ID="..." # your API Key from Infura account
ETHERSCAN_API_KEY="..." # your Etherscan API key
Next, open the deploy_parameters.json file in vim editor:
cd ~/zkevm-contracts/deployment
cp deploy_parameters.json.example deploy_parameters.json
vim deploy_parameters.json
Only fill in the commented fields in your deploy_parameters.json file:
{
"realVerifier": true,
"trustedSequencerURL": "<http://X.X.X.X:8545>", // your public IP
"networkName": "zkevm",
"version": "0.0.1",
"trustedSequencer": "", // from wallets.txt Trusted Sequencer address
"chainID": 42069, // put any id you prefer
"trustedAggregator": "", // from wallets.txt Trusted Aggregator address
"trustedAggregatorTimeout": 604799,
"pendingStateTimeout": 604799,
"forkID": 4,
"admin": "", // from wallets.txt Deployment Address address
"zkEVMOwner": "", // from wallets.txt Deployment Address address
"timelockAddress": "", // from wallets.txt Deployment Address address
"minDelayTimelock": 1,
"salt": "0x0000000000000000000000000000000000000000000000000000000000000000",
"initialZkEVMDeployerOwner": "", // from wallets.txt Deployment Address address
"maticTokenAddress": "", // put existing contract address or leave empty to auto-deploy a new contract
"zkEVMDeployerAddress": "", // put existing contract address or leave empty to auto-deploy a new contract
"deployerPvtKey": "",
"maxFeePerGas": "",
"maxPriorityFeePerGas": "",
"multiplierGas": ""
}
Caution
Get some GöETH
You will need to send 0.5 GöETH to the deployment address wallet 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, note this can sometimes be 0 for testnet:
ETHERSCAN_API_KEY="YOUR_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.
vim ~/zkevm-contracts/deployment/helpers/deployment-helpers.js
const gasPriceKeylessDeployment = "50"; // 50 gwei
Deploy contracts¶
cd ~/zkevm-contracts/
npm i @openzeppelin/hardhat-upgrades
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.
