# Sample Implementation

**Example Implementation**: <https://github.com/HeyElsa/elsa-widget-testdapp>

This is a chain-agnostic implementation and any type of wallet can be integrated. Both dApps with browser wallets and dApps with embedded wallets (e.g scribble) can implement it. For wallet-related transactions like sign transaction, connect wallet etc, the widget sends requests to the dApp through events and the dApp processes these events and sends back the response. Security-related content has been updated in the technical docs. Complete implementation of the widget is available in the [Example code](https://github.com/HeyElsa/elsa-widget-testdapp). Features implemented are:

1. Knowledge base querying,
2. Actions: Send and Swap transactions are covered.

Supported chains in the widget are :

1. Ethereum
2. Base
3. Soneium
4. Polygon
