UI#

In addition to SDK, we also provide a UI interface. If using the UI connection, and the DApp is operating in Telegram, users can choose to open the mobile App Wallet or stay in Telegram and launch the OKX Mini Wallet.

Installation and Initialization#

Make sure to update the OKX App to version 6.92.0 or later to begin access:

To integrate OKX Connect into your DApp, you can use npm:

npm install @okxconnect/ui
npm install @okxconnect/aptos-provider

Before connecting to the wallet, you need to create an object that can provide a UI interface for subsequent operations such as connecting to the wallet and sending transactions.

OKXUniversalConnectUI.init(dappMetaData, actionsConfiguration, uiPreferences, language)

Request parameters

• dappMetaData - object
  • name - string: The name of the application, will not be used as a unique representation.
  • icon - string: URL of the application icon, must be in PNG, ICO, etc. SVG icons are not supported. SVG icons are not supported. It is best to pass a url pointing to a 180x180px PNG icon.
• actionsConfiguration - object
  • modals - (‘before’ | ‘success’ | ‘error’)[] | ‘all’ The modes of displaying alerts during transaction, defaults to ‘before’.
  • returnStrategy -string ‘none’ | ${string}://${string}; for app wallet, specify the return strategy for the deep link when the user signs/rejects the request, if it is in telegram, you can configure tg://resolve
  • tmaReturnUrl -string ‘back’ | ‘none’ | ${string}://${string}; For Telegram Mini Wallet, specify the return policy of deep link when user signs/rejects the request, if it's in telegram, you can configure tg://resolve none means no processing after signing; default is back;
• uiPreferences -object
  • theme - Theme can be: THEME.DARK, THEME.LIGHT, ‘SYSTEM’.
• language - ‘en_US’ | ‘ru_RU’ | ‘zh_CN’ | ‘ar_AE’ | ‘cs_CZ’ | ‘de_DE’ | ‘es_ES’ | ‘es_LAT’ | ‘fr_FR’ | ‘id_ID’ | ‘it_IT’ | ‘nl_NL’ | ‘pl_PL’ | ‘pt_BR’ | ‘pt_PT’ | ‘ro_RO’ | ‘tr_TR’ | ‘uk_UA’ | ‘vi_VN’. , defaults to en_US
