# Integration

#### Part 1: Importing Required Libraries

```javascript
javascriptCopy codeconst ethers = require('ethers');
```

#### Part 2: Setting Contract Address and ABI

```javascript
javascriptCopy codeconst contractAddress = 'YOUR_CONTRACT_ADDRESS';
const abi = [
    // Your contract ABI here
];
```

#### Part 3: Connecting to Ethereum Network

```javascript
javascriptCopy codeconst provider = new ethers.providers.JsonRpcProvider('YOUR_JSON_RPC_PROVIDER_URL');
```

#### Part 4: Setting Up Signer

```javascript
javascriptCopy codeconst privateKey = 'YOUR_PRIVATE_KEY';
const wallet = new ethers.Wallet(privateKey, provider);
```

#### Part 5: Creating Contract Instance

```javascript
javascriptCopy codeconst contract = new ethers.Contract(contractAddress, abi, wallet);
```

#### Part 6: Interacting with Contract Methods

```javascript
javascriptCopy codeasync function submitKYC(name, userId) {
    const tx = await contract.submitKYC(name, userId);
    await tx.wait();
    console.log('KYC submitted successfully.');
}

async function verifyKYC(index) {
    const tx = await contract.verifyKYC(index);
    await tx.wait();
    console.log('KYC verified successfully.');
}

async function getKYCDetails(index) {
    const details = await contract.getKYCDetails(index);
    console.log('KYC Details:', details);
}
```

#### Part 7: Example Usage

```javascript
javascriptCopy code// Example usage
submitKYC("John Doe", "123456789");
verifyKYC(0);
getKYCDetails(0);
```

Remember to replace `'YOUR_CONTRACT_ADDRESS'`, `'YOUR_JSON_RPC_PROVIDER_URL'`, and `'YOUR_PRIVATE_KEY'` with your actual contract address, JSON RPC provider URL, and private key respectively.
