Use Blocto wallet SDK with your existing ethers integration

Integrate with ethers.js

You can use Blocto wallet service with your current ethers integration with only a few simple lines of code.

{% hint style="warning" %} Note that Blocto SDK for EVM-compatible chains is still in Beta. APIs are subject to breaking changes. {% endhint %}

Installation

Install from npm/yarn/pnpm

{% tabs %} {% tab title="npm" %}

npm i ethers @blocto/sdk

{% endtab %}

{% tab title="yarn" %}

yarn add ethers @blocto/sdk

{% endtab %}

{% tab title="pnpm" %}

pnpm add ethers @blocto/sdk

{% endtab %} {% endtabs %}

Usage

Initiate Blocto SDK and ethers

import { ethers } from "ethers";
import BloctoSDK from '@blocto/sdk'

const bloctoSDK = new BloctoSDK({
  ethereum: {
    defaultChainId: '0x1',
    switchableChains: [
      {
        chainId: '0x1',
        rpcUrls: ['https://mainnet.infura.io/v3/...'],
      },
      {
        chainId: '0xa4b1',
        rpcUrls: ['https://arb1.arbitrum.io/rpc'],
      },
      ...
    ],
  },
  // (optional) Blocto app ID
  appId: 'YOUR_BLOCTO_APP_ID',
})

// If using ethers.js v6 or after
const provider = new ethers.BrowserProvider(bloctoSDK.ethereum);
// If using ethers.js v5, this will be
// const provider = new ethers.providers.Web3Provider(bloctoSDK.ethereum);

// Blocto SDK requires requesting permission to connect users accounts
await provider.send("eth_requestAccounts", []);

// Use getSigner to get access with write operations like send transaction
const signer = provider.getSigner()
// Send transaction
const txn = await signer.sendTransaction(transaction);

Now you can then use the provider and signer object for on-chain interactions. For more documentation for what you can do with ethers.js, please check out
