To make these instructions concrete, we have created a sample global wallet called **Rapidfire ID**. To interact with it, you can find its SDK in the NPM package directory: [@rapidfire/id](https://www.npmjs.com/package/@rapidfire/id).

You can check out the GitHub [repository for Rapidfire Wallet](https://github.com/openfort-xyz/ecosystem-sample) to learn how to create your own wallet.
