Biconomy SDK Node Client

Node Client is the api client package that communicate with Biconomy SDK backend node to fetch needed smart contract wallet data i.e supported chains list, transaction history, balances e.t.c

Installation

yarn add @biconomy/node-client

OR

npm install @biconomy/node-client

Usage

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

// initialisation

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

Fetch Supported Chains List

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

Fetch Transactions By Address

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

Get Transaction By Hash

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

Get Smart Contract Wallet Balances

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)
