Activate forced transactions

Continue with the sixth step of this deployment-guide where you activate forced transactions, as well as bridging and claiming assets.

Activate forced transactions

You can check out this document to learn more about forced batches of transactions.

cd ~/zkevm-contracts
npx hardhat console --network goerli
const zkevm = await ethers.getContractFactory("PolygonZkEVM");
const zkevmContract = zkevm.attach("_polygonZkEVMAddress_"); // From ~/zkevm-contracts/deployments/goerli_*/deploy_output.json polygonZkEVMAddress

const provider = ethers.getDefaultProvider(""); // set Geth Goerli RPC endpoint
const privateKey = ""; // Deployment Address prvkey from wallet.txt
const wallet = new ethers.Wallet(privateKey, provider);

const zkevmContractWallet = zkevm.connect(wallet);

await zkevmContract.activateForceBatches();

Provide L1 ETH to the bridge

Run the below commands in CLI to create a bridge transaction and send L1 Ether to the zkEVM Bridge.

mkdir -p ~/zkevm/initial-bridge
cd zkevm/initial-bridge

vim main.go

Populate the main.go file with following variables:

l1BridgeAddr       = "" // ~/zkevm-contracts/deployments/goerli_*/deploy_output.json: polygonZkEVMBridgeAddress

l1AccHexAddress    = "" // ~/zkevm-contracts/wallets.txt: sequencer address
l1AccHexPrivateKey = "" // ~/zkevm-contracts/wallets.txt: sequencer prvkey
l1NetworkURL       = "http://X.X.X.X:8545"      // set your public IP

Initialize a new Go module with the module path

go mod init
go mod tidy
go run main.go

# 2023-06-07T06:29:14.211Z      INFO    initial-bridge/main.go:46       Success!        {"pid": 776268, "version": "v0.1.0"}

Claim your L2 zkETH

After sending your first bridge transaction to your zkEVM network, create a forced claim to get the zkETH in L2.

mkdir -p ~/zkevm/initial-claim
cd ~/zkevm/initial-claim

vim main.go

Open main.go and update the following parameters:

const (
    l2BridgeAddr = ""  // ~/zkevm-contracts/deployments/goerli_*/deploy_output.json: polygonZkEVMBridgeAddress
    zkevmAddr    = ""  // ~/zkevm-contracts/deployments/goerli_*/deploy_output.json: polygonZkEVMAddress

    accHexAddress    = ""  // ~/zkevm-contracts/wallets.txt: sequencer address
    accHexPrivateKey = ""  // ~/zkevm-contracts/wallets.txt: sequencer prvkey
    l1NetworkURL     = "http://X.X.X.X:8545"  // public IP
    l2NetworkURL     = "http://X.X.X.X:8123"  // public IP
    bridgeURL        = "http://X.X.X.X:8080"  // public IP

    l2GasLimit = 1000000

    mtHeight      = 32
    miningTimeout = 180

Time to execute the claim transaction:

go mod init
go mod tidy
go get
go run main.go

# 2023-06-07T06:41:50.731Z     INFO    initial-claim/main.go:196       Success!!!!     {"pid": 783804, "version": "v0.1.0"}


Congratulations on reaching this far in setting up your own zkEVM network. Your network is live on the Testnet and you can send transactions to verify the same. Also, we have provided a Goerli full node setup guide below in case you are looking for one.
