UI#

In addition to the SDK, we also provide a UI interface. If you choose to integrate through the UI, and if the DApp is running inside Telegram, users can choose to stay within Telegram and invoke the mobile App wallet or the OKX Mini Wallet.

Installation and Initialization#

Make sure to update the OKX App to version 6.90.1 or later to begin access:

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

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

Before connecting to a 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

    • defaultChain?: string; default chain
  • optionalNamespaces - [namespace: string]: ConnectNamespace; optional information for requesting a connection, the key for for Solana is 'solana' If the corresponding chain information is not supported by the wallet, the connection can still be made
    • chains: string[]; Chain id information, chain information, chain information, chain information
      • defaultChain?: string; defaultChain

Return Value

• Promise<SessionTypes.Struct | undefined>
  • topic: string; session identifier

  • sessionConfig?: SessionConfig
    • dappInfo: object DApp information
      • name:string
      • dappInfo: object DApp info; name:string

Example

var session = await universalUi.openModal({
    namespaces: {
        solana: {
            chains: ["solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp", // solana mainnet
            //  "solana:4uhcVJyU9pJkvQyS88uRDiswHXSCkY3z",// solana testnet
            //  "sonic:4uhcVJyU9pJkvQyS88uRDiswHXSCkY3z",// sonic testnet
            ],
        }
    }
})

Determine if the wallet is connected#

Gets whether the wallet is currently connected.

Return Value

• boolean

Example

universalUi.connected()

Sending Signature and Transactions#

Methods to send messages to the wallet, support signature, transaction.

First create an OKXSolanaProvider object, pass OKXUniversalProviderUI into the constructor, when calling OKXSolanaProvider related methods, the actionsConfiguration.mode configuration will be handled according to the values passed during init;

import { OKXSolanaProvider } from "@okxconnect/solana-provider";
let okxSolanaProvider = new OKXSolanaProvider(universalUi)

Return Value

• Promise - string transactionhash

Get wallet account information#

okxSolanaProvider.getAccount(chain)

Request parameters

• chain: string, get the chain id of the wallet address, if not passed then the first connected svm address will be taken by default.

let provider = new OKXSolanaProvider(universalUi)
const transaction = new Transaction({

Disconnect wallet#

Disconnect the connected wallet and delete the current session. If you want to switch the connected wallet, please disconnect the current wallet first.

universalUi.disconnect()

Event#

// Generate universalLink
universalUi.on("display_uri", (uri) => {
    console.log(uri);
}).
// Session information changes will trigger this event;
universalUi.on("session_update", (session) => {
  console.log(JSON.stringify(session));
});
