yarn

yarn add @web3-onboard/core @web3-onboard/blocto ethers

pnpm

pnpm add @web3-onboard/core @web3-onboard/blocto ethers

Step 1 - Import Web3-Onboard

Import Web3-Onboard, ethers, and bloctoWallet.

import Onboard from "@web3-onboard/core";
import bloctoModule from "@web3-onboard/blocto";
import { ethers } from "ethers";
import { bscTestnet, sepolia } from 'wagmi/chains'

Step 2 - Configure and add button

Configure your desired chains and generate the required connectors.

const blocto = bloctoModule();

const onboard = Onboard({
  wallets: [blocto],
  chains: [bscTestnet, sepolia],
});

// connect wallet
const connectWallet = async () => {
  await onboard.connectWallet();
};

const sendTx = async () => {
  // create an ethers provider with the last connected wallet provider
  // if using ethers v6 this is:
  // ethersProvider = new ethers.BrowserProvider(wallet.provider, 'any')
  const ethersProvider = new ethers.providers.Web3Provider(
    wallets[0].provider,
    "any"
  );
  const signer = ethersProvider.getSigner();
  // send a transaction with the ethers provider
  const txn = await signer.sendTransaction({
    to: "0x",
    value: 100000000000000,
  });
  const receipt = await txn.wait();
  console.log(receipt);
};

const App = () => {
  return (
    <button onClick={connectWallet}>
        connect wallet
    </button>
  );
};

Now you can easily use Web3-Onboard connect BloctoWallet

npm i @web3-onboard/react @web3-onboard/blocto ethers

yarn

yarn add @web3-onboard/react @web3-onboard/blocto ethers

pnpm

pnpm add @web3-onboard/react @web3-onboard/blocto ethers

Step 1 - Import Web3-Onboard

Import Web3-Onboard, ethers, and bloctoWallet.

import injectedModule from "@web3-onboard/injected-wallets";
import { init, useConnectWallet } from "@web3-onboard/react";
import bloctoModule from "@web3-onboard/blocto";
import { ethers } from "ethers";

Step 2 - Configure

Configure your desired chains and generate the required connectors.

const bscTestnet = {
  id: "0x61",
  token: "BNB",
  label: "Polygon",
  rpcUrl: "https://data-seed-prebsc-1-s1.binance.org:8545/"
};

const chains = [polygonTestnet];
const wallets = [bloctoModule()];

const web3Onboard = init({
  wallets,
  chains,
  appMetadata: {
    name: "Web3-Onboard Demo",
    icon: "<svg>My App Icon</svg>",
    description: "A demo of Web3-Onboard."
  }
});

Step 3 - Wrap providers

Wrap your application with Web3OnboardProvider.

  <Web3OnboardProvider web3Onboard={web3Onboard}>
    <App />
  </Web3OnboardProvider>

Step 4 - Inject provider and connect wallet

  const [{ wallet, connecting }, connect, disconnect] = useConnectWallet();

  const ethersProviderRef = useRef();
  if (wallet && !ethersProviderRef.current) {
    // if using ethers v6 this is:
    // ethersProvider = new ethers.BrowserProvider(wallet.provider, 'any')
    ethersProviderRef.current = new ethers.providers.Web3Provider(
      wallet.provider,
      "any"
    );
  }

const connectWallet = async () => {

}

const App = () => {
  return (
      <button
        disabled={connecting}
        onClick={() => (wallet ? disconnect(wallet) : connect())}
      >
        <span>
          {connecting ? "Connecting" : wallet ? "Disconnect" : "Connect"}
        </span>
      </button>
  );
};
