Biconomy SDK 节点客户端

节点客户端是通信的 api 客户端软件包 双经济 SDK 获取所需智能合同钱包数据的后端节点, 即支持的链条列表, 交易历史, 余额 e. t. c

安装

yarn add @biconomy/node-client

或

npm install @biconomy/node-client

使用量

// import package
import NodeClient from '@biconomy/node-client'

// initialisation

const nodeClient = new NodeClient({ txServiceUrl: 'https://sdk-backend.staging.biconomy.io/v1' })

获取支持的链条列表

const supportedChainsList = await nodeClient.getAllSupportedChains()
console.log('supportedChainsList ', supportedChainsList)

获取交易 通过地址

const chainId = 80001
const address = '0xabc......'
const trxHistory = await nodeClient.getTransactionByAddress(chainId, address)
console.log('trxHistory ', trxHistory)

通过散列获取交易

const txHash = '0x........'
const trxDetail = await nodeClient.getTransactionByHash(txHash)
console.log('trxDetail ', trxDetail)

获取智能合同钱包余额

import { BalancesDto } from '@biconomy/node-client'

import { ChainId } from '@biconomy/core-types'

const address = '0xabc......'

const balanceParams: BalancesDto =
      {
          // if no chainId is supplied, SDK will automatically pick active one that
         //  is being supplied for initialization

        chainId: ChainId.MAINNET, // chainId of your choice
        address: address,
        // If empty string you receive balances of all tokens watched by Indexer
        // you can only whitelist token addresses that are listed in token respository
        // specified above ^
        tokenAddresses: [],
      };

const balFromSdk = await nodeClient.getAllTokenBalances(balanceParams);
console.info("balFromSdk ", balFromSdk);

const usdBalFromSdk = await nodeClient.getTotalBalanceInUsd(balanceParams);
console.info("usdBalFromSdk ", usdBalFromSdk)
