⚠
THIS IS A TESTING WALLET.
* Save your Public Address and Private Key.
* Fund your Address with the tokens of all the networks.
* For ETH on Polygon zkEVM Testnet and Polygon Mumbai Testnet use [Polygon Faucet.](https://faucet.polygon.technology/)
* For ETH on Sepolia use [Alchemy Faucet](https://sepoliafaucet.com/).
## Keys for Validators
For this tutorial, we will be using the default [Hyperlane's Multisig ISM](https://docs.hyperlane.xyz/docs/protocol/sovereign-consensus/multisig-ism). Multisig ISM is a module that takes several signatures from validators before completing the transaction. Therefore, we will be using **4 addresses** with threshold **one**.
You can take any 4 of your Public Addresses, and keep them handy for later use.
> Make sure to have a Private Key secured for the Public addresses you will be using.
> You can generate Key Pairs using the above method.
# Setting up the Repo
The Hyperlane Core team provided us with a repository that you can use to deploy Hyperlane on your preferred chain.
Follow these steps to set up the Hyperlane Deployment repo:
* Open your terminal at your preferred directory.
* ```bash
git clone https://github.com/hyperlane-xyz/hyperlane-deploy.git
```
* ```bash
cd hyperlane-deploy
```
* ```bash
yarn install
```
# Adding the custom chain
Hyperlane's core team has provided a few chains in the SDK. You can check them out [here](https://docs.hyperlane.xyz/docs/resources/addresses).
To add a chain apart from the provided chains, follow these steps:
* Open `config/chains.ts` There you will find the configuration example for adding new chains.
* Add the following configuration for the Polygon zkEVM Testnet:
```typescript
polygonzkevmtestnet: {
name: 'polygonzkevmtestnet',
chainId: 1442,
protocol: ProtocolType.Ethereum,
nativeToken: {
name: 'ether',
symbol: 'ETH',
decimals: 18,
},
rpcUrls: [
{
http: 'https://rpc.public.zkevm-test.net',
},
],
blockExplorers: [
{
name: 'Polygon Scan',
url: 'https://testnet-zkevm.polygonscan.com',
apiUrl: 'https://api-zkevm.polygonscan.com/api',
},
],
isTestnet: true,
},
```
# Adding the Validator Keys
For this tutorial, we are using the default [Multisig](https://docs.hyperlane.xyz/docs/protocol/sovereign-consensus/multisig-ism) as our Interchain Security Module.
Follow these steps, for setting up the keys:
* Open `config/multisig_ism.ts`. There you will find the configuration example for adding new chains and their keys.
* Add the keys for your validator:
```typescript
polygonzkevmtestnet: {
threshold: 1,
type: ModuleType.LEGACY_MULTISIG,
validators: [
'0xabcabcabcabcabcabcabcabcabcabcabcabcabca',
'0xabcabcabcabcabcabcabcabcabcabcabcabcabca',
'0xabcabcabcabcabcabcabcabcabcabcabcabcabca',
'0xabcabcabcabcabcabcabcabcabcabcabcabcabca',
],
},
```
* `threshold` is 1 which means only one of the validator's signatures is required.
> Woohoooo!!! You are done with the setup for the deployment of HYPERLANE on Polygon zkEVM testnet with remotes Mumbai and Sepolia.

# Deploying the Hyperlane
To deploy Hyperlane, run the following command on your terminal.
```bash
DEBUG=hyperlane* yarn ts-node scripts/deploy-hyperlane.ts --local polygonzkevmtestnet \
--remotes mumbai sepolia \
--key 0xbeda2b3910bae7dbfb4e65e9c0931f001066d4f0df257b77ad55093fa271bde2
```
In the above command,
* we are running the `deploy-hyperlane.ts` script
* with `polygonzkevmtestnet` as `local` chain and
* `mumbai` and `sepolia` as remotes. Since `mumbai` and `sepolia` are already provided by the Hyperlane SDK we don't need to add the configurations again.
* the value after `key` param is your **private key** to the address that contains funds for all the networks.
After running the command, wait for a few minutes till your terminal looks like this 👇🏻

Congrats!!! You just **Deployed** Hyperlane on Polygon zkEVM Testnet.
But to test this out, you will need to run your Validators and Relayers for all the chains you deployed (local + remote). To learn how to setup Validators and Relayers check them out 👇🏻
