# EVM

* We are using `ethers.js` for this particular example
* Use `signer.signMessage` message from `Signer` class

```tsx
const message = await generateMessage()

const signer = new ethers.Wallet()

const signature = await signer.signMessage(message)

// OR

const signature = await signer.signMessage(Buffer.from(message))
```
