# Integrate Embedded Wallets with the Polygon Blockchain in Node

> Integrate Embedded Wallets with the Polygon Blockchain in Node | Embedded Wallets

While using the Web3Auth Node SDK, you get a Ethers Signer on successful authentication. This signer can be used with libraries like [`ethers.js`](https://docs.ethers.io/v5/getting-started/) etc. to make [Polygon](https://polygon.technology/) blockchain calls like getting the user's `account`, fetching `balance`, `sign transaction`, `send transaction`, `read` from and `write` to the smart contract, etc. We have highlighted a few here to get you started.
