🛠️ Wallet Implementation Guide

Wallets implement a "Provider" interface. The latest spec uses a simple JS Object exposing a .request(method: string, params?: object) method.

Pseudo-code:

window.MyProvider = {
  async request(method, params) {
    // Somehow communicate with the wallet (e.g. via events)

    // Recommendation: Create a JSON RPC 2.0 request object
    // https://www.jsonrpc.org/specification

    return Promise.resolve({
      // Respond with a JSON RPC 2.0 response object
      id: crypto.randomUUID(), // required, same as request
      jsonrpc: '2.0', // required

      // `.result` is required on success
      result: {
        // object matching specified RPC methods
      },

      // `.error` is required on error
      error: {
        // Use existing codes from https://www.jsonrpc.org/specification#error_object
        code: number, // required, integer
        message: string, // recommended, single sentence
        data: object, // optional
      },
    });
  },
  isMyWallet: true, // optional, a way of identifying the wallet for developers
};

window.wbip_providers = window.wbip_providers || [];
window.wbip_providers.push({
  // `WbipProvider` type
    /** The global "path" of the provider (e.g. `"MyProvider"` if registered at `window.MyProvider`) */
  id: 'MyProvider',
  /** The name of the provider, as displayed to the user */
  name: 'My Wallet';
  /** The data URL of an image to show (e.g. `data:image/png;base64,iVBORw0...`) @see https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URLs */
  icon?: 'data:image/png;base64,iVBORw0...';
  /** Web URL of the provider */
  webUrl?: 'https://mywallet.example.com';

  // Addional URLs
  chromeWebStoreUrl?: string;
  mozillaAddOnsUrl?: string;
  googlePlayStoreUrl?: string;
  iOSAppStoreUrl?: string;
});

JSON RPC 2.0

Wallets may add their own unstandardized methods. However, the minimum recommended methods are:

• getAddresses WBIP
• sendTransfer WBIP
• signPsbt WBIP
• stx_getAddresses SIP-030
• stx_transferStx SIP-030
• stx_callContract SIP-030
• stx_signMessage SIP-030
• stx_signStructuredMessage SIP-030
