@okxconnect/aptos-provider v1.4.2

Aptos

安装及初始化

请确保更新到 6.92.0或以后版本，即可开始接入：将 OKX Connect 集成到您的 DApp 中，可以使用 npm:

npm install @okxconnect/aptos-provider

连接钱包之前，需要先创建一个对象，用于后续连接钱包、发送交易等操作。

OKXUniversalProvider.init({dappMetaData: {name, icon}})

请求参数

• dappMetaData - object
  • name - string: 应用名称，不会作为唯一表示
  • icon - string: 应用图标的 URL。必须是 PNG、ICO 等格式，不支持 SVG 图标。最好传递指向 180x180px PNG 图标的 url。

返回值

• OKXUniversalProvider

示例

import { OKXUniversalProvider } from "@okxconnect/universal-provider";

const okxUniversalProvider = await OKXUniversalProvider.init({
    dappMetaData: {
        name: "application name",
        icon: "application icon url"
    },
})

连接钱包

连接钱包去获取钱包地址，作为标识符和用于签名交易的必要参数;

okxUniversalProvider.connect(connectParams: ConnectParams);

请求参数

• connectParams - ConnectParams
  • namespaces - namespace: string: ConnectNamespace ; 请求连接的必要信息，EVM系的key为"eip155"，Aptos系的key为"aptos" ，如果请求的链中，有任何一个链钱包不支持的话，钱包会拒绝连接；
    • chains: string[]; 链id信息,
    • rpcMap?: chainId: string: string; rpc 信息，配置了rpc url才能请求链上rpc信息；
    • defaultChain?: string; 默认链
  • optionalNamespaces - namespace: string: ConnectNamespace; 请求连接的可选信息， EVM系的key为"eip155"，Aptos系的key为"aptos" ，如果对应的链信息钱包不支持，依然可以连接；
    • chains: string[]; 链id信息,
      • rpcMap?: chainId: string: string; rpc 信息；
      • defaultChain?: string; 默认链
  • sessionConfig: object
    • redirect: string 连接成功后的跳转参数，如果是Telegram中的Mini App，这里可以设置为Telegram的deeplink: "tg://resolve"

返回值

• Promise<SessionTypes.Struct | undefined>
  • topic: string; 会话标识；
  • namespaces: Record<string, Namespace>; 成功连接的namespace 信息；
    • chains: string[]; 连接的链信息；
    • accounts: string[]; 连接的账户信息；
    • methods: string[]; 当前namespace下，钱包支持的方法；
    • rpcMap?: chainId: string: string; rpc 信息；
    • defaultChain?: string; 当前会话的默认链
  • sessionConfig?: SessionConfig
    • dappInfo: object DApp 信息；
      • name:string
      • icon:string
    • redirect?:string, 连接成功后的跳转参数；

示例

var session = await okxUniversalProvider.connect({
    namespaces: {
        aptos: {
            chains: ["aptos:mainnet", //aptos mainnet
                "movement:testnet",//movement testnet
            ],
        }
    },
    sessionConfig: {
        redirect: "tg://resolve"
    }
})

发送签名和交易

首先创建一个OKXAptosProvider对象，构造函数传入OKXUniversalProvider

import { OKXAptosProvider } from "@okxconnect/aptos-provider";
let okxAptosProvider = new OKXAptosProvider(okxUniversalProvider)

获取钱包地址及publicKey

okxAptosProvider.getAccount(chain);

请求参数

• chain: string, 获取钱包地址的链Id,不传则默认取第一个连接的aptos系地址

返回值

• Object
  • address: string 钱包地址
  • publicKey: string 公钥

签名

okxAptosProvider.signMessage(message, chain);

请求参数

• message - object - address?: boolean; // Should we include the address of the account in the message - application?: boolean; // Should we include the domain of the DApp - chainId?: boolean; // Should we include the current chain id the wallet is connected to - message: string; // The message to be signed and displayed to the user - nonce: string; // A nonce the DApp should generate
• chain: string, 请求签名执行的链，建议传递此参数；连接多条链时为必传参数；

返回值

• Promise - object

  • address: string;
  • application: string;
  • chainId: number;
  • fullMessage: string; // The message that was generated to sign
  • message: string; // The message passed in by the user
  • nonce: string;
  • prefix: string; // Should always be APTOS

  • signature: string; // The signed full message

签单笔交易

okxAptosProvider.signTransaction(transaction, chain);

请求参数

• transaction - object | SimpleTransaction 交易数据对象
• chain: string, 请求签名执行的链，建议传递此参数；连接多条链时为必传参数；

返回值

• Promise - Buffer 签名buffer;

签多笔交易并上链

okxAptosProvider.signAndSubmitTransaction(transactions, chain);

请求参数

• transactions - object | SimpleTransaction 交易数据对象
• chain: string, 请求签名执行的链，建议传递此参数；连接多条链时为必传参数；

返回值

• Promise - string 交易hash;

示例

//签名消息
let data = {
    address:true,
    application:true,
    chainId:true,
    message:"Hello OKX",
    nonce:"1234"
}

let provider = new OKXAptosProvider(window.provider)
let message = await provider.signMessage(data, "aptos:mainnet")

//返回值 {"address":"0x2acddad65c27c6e5b568b398f0d1d01ebb8b55466461bbd51c1e42763a92fdfe","application":"http://192.168.101.13","chainId":"aptos:mainnet","fullMessage":"APTOS\naddress: 0x2acddad65c27c6e5b568b398f0d1d01ebb8b55466461bbd51c1e42763a92fdfe\napplication: http://192.168.101.13\nchainId: aptos:mainnet\nmessage: 123 签名测试!\nnonce: 1234","message":"123 签名测试!","nonce":"1234","prefix":"APTOS","signature":"0xef4e587f537b80a2f4e424079984b80e130c92d939a92225764be00ed36486521e8857b8a222de4023c5f4d2e9fd2f62c26ca8a43694660583c8a5d4328da303","verified":true}

断开钱包连接

断开已连接钱包,并删除当前会话,如果要切换连接钱包,请先断开当前钱包。

okxUniversalProvider.disconnect();
