# Cross-app wallet (Ecosystem SDK)

Openfort **Cross-app wallets** integrate onboarding, authentication, payments, and recovery with no app or extension required. Projects use the [Ecosystem SDK](https://www.npmjs.com/package/@openfort/ecosystem-js), a TypeScript library, to bootstrap the cross-app wallet.

:::note
Cross-app wallets are whitelabel and allow you to own the entire developer experience. **In short, you own the *npm package* the developer installs.**
:::

We have created a *sample* cross-app wallet called **Rapidfire ID** to showcase how the Ecosystem SDK builds one. To interact with it, developers install its SDK: NPM package directory: [@rapidfire/id](https://www.npmjs.com/package/@rapidfire/id). Check out the GitHub [repository for Rapidfire Wallet](https://github.com/openfort-xyz/ecosystem-sample).

Try signing into your **Rapidfire** account:

Supported wallet connection libraries include:

* [Wagmi](https://wagmi.sh/)
