# Bridges
## Introduction
The Etherspot BUIDLER component comes with a built-in block to facilitate swapping assets across chains or Layer 2 chains.
Users can select a source token and amount, and a destination asset on a different chain.
Etherspot will take care of finding the best route and display it to the user.
Once the user reviews this, they are shown a summary and they can choose whether to execute the transaction.
### Implementation
Copy and paste the code below to get started.
```jsx
import {
Etherspot,
TRANSACTION_BLOCK_TYPE,
} from "@etherspot/react-transaction-buidler";
// ...
return (
);
```
