Wallet Developers

If you're a wallet developer and you want your wallet to be added to the kit, you can do it by creating a "module" compatible with the kit.

This module needs to follow this interface here

/**
 * The Kit Actions are the methods the kit use to interact with the Wallet/Service
 */
export interface KitActions {
  /**
   * Function used to request the public key from the active account or
   * specific path on a wallet.
   *
   * @param params
   * @param params.path - The path to tell the wallet which position to ask. This is commonly used in hardware wallets.
   *
   * @return Promise<{ address: string }>
   */
  getAddress(params?: { path?: string }): Promise<{ address: string }>;

  /**
   * A function to request a wallet to sign a built transaction in its XDR mode
   *
   * @param xdr - A Transaction or a FeeBumpTransaction
   * @param opts - Options compatible with https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0043.md#signtransaction
   * @param opts.networkPassphrase - The Stellar network to use when signing
   * @param opts.address - The public key of the account that should be used to sign
   * @param opts.path - This options is added for special cases like Hardware wallets
   *
   * @return Promise<{ signedTxXdr: string; signerAddress: string }>

      path?: string;
      submit?: boolean;
      submitUrl?: string;
    }
  ): Promise<{ signedTxXdr: string; signerAddress?: string }>;

  /**
   * A function to request a wallet to sign an AuthEntry XDR.

   * handy when you are dealing with a wallet that doesn't allow you to specify which network to use (For example Lobstr and Rabet)

 * specific type of wallet/service. There are some modules that are already
 * in the kit but any wallet developer can create their own plugins
 */

   * The Module type is used for filtering purposes, define the correct one in
   * your module so we display it accordingly
   */

   * This ID of the module, you should expose this ID as a constant variable
   * so developers can use it to show/filter this module if they need to.
   */

   * This is the name the kit will show in the builtin Modal.
   */

   * get the product.

   */

  /**
   * This function should return true is the wallet is installed and/or available.
   * If for example this wallet/service doesn't need to be installed to be used,
   * return `true`.
   *
   * Important:
   * Your wallet/library needs to be able to answer this function in less than 500ms.
   * Otherwise, the kit will show it as unavailable

After you have your module done, open a PR with the module and we will review it.
