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 6.90.1 or later to start accessing it:

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

npm install @okxconnect/ui
npm install @okxconnect/sui-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 tg, 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 tg, 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

OKXUniversalConnectUI

Example

import { OKXUniversalConnectUI } from "@okxconnect/ui";

const okxUniversalConnectUI = await OKXUniversalConnectUI.init({
    dappMetaData: {
        icon: "https://static.okx.com/cdn/assets/imgs/247/58E63FEA47A2B7D7.png",
        name: "OKX Connect Demo"
    },
    actionsConfiguration: {
        returnStrategy: 'tg://resolve',
        modals:"all"
    },
    language: "en_US",
    uiPreferences: {
        theme: THEME.LIGHT
    },
});

Connect to OKX Wallet#

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

okxUniversalConnectUI.connect(connectParams: ConnectParams);

Request Parameters

connectParams - ConnectParams
- namespaces - [namespace: string]: ConnectNamespace ; information necessary to request a connection, the key for Sui is 'sui'. If any of the requested chains are not supported by the wallet, the wallet will reject the connection;
  - chains: string[]; chain id information, the chain's key is 'sui', the wallet will reject the connection if any of the requested chains is not supported.
- optionalNamespaces - [namespace: string]: ConnectNamespace; optional information for requesting connection, the key for EVM is 'eip155', the key for Sui is 'sui'. If the corresponding chain information is not supported by the wallet, the connection can still be made;
  - chains: string[]; chain id info
- sessionConfig: object
  - redirect: string Jump parameter after successful connection, if it is Mini App in Telegram, here can be set to Telegram's deeplink: 'tg://resolve'

Return value

Promise <SessionTypes.Struct | undefined>
- topic: string; The session identifier;
- namespaces: Record<string, Namespace>; namespace information for a successful connection;
  - 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; default chain for the current session
- sessionConfig?: SessionConfig
  - dappInfo: object DApp information;
    - name:string
    - icon:string
  - redirect?: string, jump parameter after successful connection;

Example

var session = await okxUniversalConnectUI.connect({
    namespaces: {
        sui: {
            chains: ["sui:mainnet"]
        }
    },
    sessionConfig: {
        redirect: "tg://resolve"
    }
})

Example

okxUniversalConnectUI.disconnect();

Sending Signature and Transactions#

This method allows sending messages to the wallet, supporting signatures, transactions.

First create an OKXSuiProvider object, passing OKXUniversalProvider into the constructor.

import { OKXSuiProvider } from "@okxconnect/sui-provider"
let suiProvider = new OKXSuiProvider(okxUniversalConnectUI)

Get Account#

suiProvider.getAccount();

Returns the value.

Object
- address: string wallet address
- publicKey: string public key (requires App 6.92.0 or later support)

Example

let result = suiProvider.getAccount()

// Return structure
{
'address": “0x7995ca23961fe06d8cea7da58ca751567ce820d7cba77b4a373249034eecca4a”,
    'publicKey": “tUvCYrG22rHKR0c306MxgnhXOSf16Ot6H3GMO7btwDI=”,
}

SignMessage#

suiProvider.signMessage(input: SuiSignMessageInput);

Request Parameters

SuiSignMessageInput - object
- message: Uint8Array

Return Value

Promise - object
- messageBytes: string
- signature: string

SignPersonalMessage#

suiProvider.signPersonalMessage(input: SuiSignMessageInput);

Request Parameters

SuiSignMessageInput - object
- message: Uint8Array

Return Value

Promise - object
- bytes: string
- signature: string

const data = [76, 111, 103, 105, 110, 32, 119, 105, 116, 104, 32, 66, 108, 117, 101, 109, 111, 118, 101];
const uint8Array = new Uint8Array(data);
let input = {
    message: uint8Array
}
let signResult1 = await suiProvider.signMessage(input)
let signResult2 = await suiProvider.signPersonalMessage(input)

Sign Transaction#

suiProvider.signTransaction(input);

Request Parameters

// txBytes and txSerialize are the serialization of the transactionBlock.
// and transactionBlock can be passed in one way or the other, but not both.
interface SuiSignTransactionBlockInput {
    transactionBlock: TransactionBlock;
    chain: IdentifierString;
    txBytes: string?;
    txSerialize: string?
}

Return Value

Promise - object
- signature: string,
- transactionBlockBytes: string

Signs a transaction and broadcasts onchain#

suiProvider.signAndExecuteTransaction(input);

Request Parameters

// txBytes and txSerialize is Serialized from transactionBlock,
// if you pass transactionBlock, then no need to pass txBytes and txSerialize
interface SuiSignTransactionBlockInput {
    transactionBlock: TransactionBlock;
    chain: IdentifierString;
    txBytes: string?;
    txSerialize: string?;

Return Value

Promise - object
- confirmedLocalExecution: bool,
- digest: string,
- txBytes: string

// Define the amount to be transferred and the destination address
const amount = 109; // Amount to be transferred
const recipientAddress = '0x'; // destination address

/// Construct a transfer transaction
const tx = new Transaction();
const [coin] = tx.splitCoins(tx.gas, [amount]);
tx.transferObjects([coin], recipientAddress)
const input = {
    transactionBlock: tx,
    chain: 'sui:mainnet',
    options: {
        showEffects: true,
    }
}

let signResult1 = await suiProvider.signTransaction(input)
let signResult2 = await suiProvider.signAndExecuteTransaction(input)
