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

Return value

        returnStrategy: 'tg://resolve',
        modals:"all",
        tmaReturnUrl:'back'
    },
    language: "en_US",
    uiPreferences: {
        theme: THEME.LIGHT
    },
});

Connect to Wallet#

Connecting to a wallet goes to get the wallet address as an identifier and the necessary parameters used to sign the transaction.

universalUi.openModal(connectParams: ConnectParams);

Request Parameters

connectParams - ConnectParams
- namespaces - [namespace: string]: ConnectNamespace ; necessary information for the requested connection, the key is 'eip155' for EVM system and 'solana' for Solana system. If any of the requested chains are not supported by the wallet, the wallet will reject the connection;
  - chains: string[]; chain id information,
  - 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;
- namespaces: Record<string, Namespace>; namespace information for successful connections;
  - chains: string[]; Chain information for the connection;
  - accounts: string[]; accounts information for the connection;
  - methods: string[]; methods supported by the wallet under the current namespace;
  - defaultChain?: string; The default chain for the current session.
- 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)

Signature#

okxSolanaProvider.signMessage(message, chain);

Request parameters

message - string, the message to be signed
chain: string, the chain to be signed, it is recommended to pass this parameter; it is mandatory to pass this parameter when connecting multiple chains; if a chain is not passed, it will be handled according to solan:mainnet or sonic:testnet;

Promise - object
- publicKey:string wallet address
- signature:Uint8Array The signature result.

Sign a single transaction#

okxSolanaProvider.signTransaction(transaction, chain)

request parameters

transaction - Transaction | VersionedTransaction transaction data object

Promise - Transaction | VersionedTransaction signed transaction object.

Signs multiple transactions#

okxSolanaProvider.signAllTransactions(transactions, chain);

request parameters

transactions - [Transaction | VersionedTransaction] array of transaction data objects

get wallet address and pubKey#

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.

Return Value

Object
- address: string wallet address
- publicKey: public key

Example

//Signing a transfer transaction on solana mainnet
let provider = new OKXSolanaProvider(universalUi)
const transaction = new Transaction({
