# 🌐 OmniCounter Example using LayerZero and zkSync
Learn how to send a cross-chain message from `optimism-goerli` to `zksync-testnet`.
## 🛠 Installation
### Prerequisites
1. NodeJS & Yarn installed.
2. Wallets funded on both `optimism-goerli` and `zksync-testnet` networks.
### Install Dependencies
Run the following command to install required dependencies:
```bash
yarn install
```
### Environment Setup
Create a `.env` file at the project root with your `PRIVATE_KEY`:
```env
PRIVATE_KEY=""
```
## 🚀 Example
OmniCounter is a simplistic contract that incorporates a counter. The only way to increment this counter is *remotely*!
### Step 1: Deploy OmniCounters
Deploy the contract on both networks:
```bash
npx hardhat --network zksync-testnet deploy --tags OmniCounter
npx hardhat --network optimism-goerli deploy --tags OmniCounter
```
### Step 2: Configure Remote Addresses
Navigate to the `setTrustedRemote.js` file under `/tasks` and add the zkSync deployed address to the following field:
```
const ZKSYNC_OMNICOUNTER = "YOUR-ZKSYNC-DEPLOYED-OMNICOUNTER-ADDRESS
```
Establish trust between contracts to enable message reception:
```bash
npx hardhat --network zksync-testnet setTrustedRemote --target-network optimism-goerli --contract OmniCounter
npx hardhat --network optimism-goerli setTrustedRemote --target-network zksync-testnet --contract OmniCounter
```
### Step 3: Send Cross-Chain Message
Time to send a cross-chain message from `optimism-goerli` to `zksync-testnet`:
```bash
npx hardhat --network optimism-goerli incrementCounter --target-network zksync-testnet
```
