# Sample Implementation **Example Implementation**: 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.
