Learn how to set up popular Web3 libraries with Para. Choose from , , or to build your EVM application.

​
Prerequisites

Before setting up Web3 libraries, you need an authenticated Para session.

Setup Para Instance

​
Installation

If using viem and the @getpara/react-sdk you can use our hook or hook to access the Viem client and account without any additional setup.
  • Ethers.js
  • Viem
  • Wagmi
npm install @getpara/ethers-v6-integration@alpha ethers@^6 --save-exact

​
Library Setup and Configuration

Configure your chosen Web3 library. You can use either a hook-based approach for React applications or a direct client setup for non-React environments or if you want to access the client outside of the ParaProvider context.
  • Hook-based (React)
  • Direct Client (Non-React)
  • Ethers.js
  • Viem
  • Wagmi
useEthers.ts
import { useClient, useAccount } from "@getpara/react-sdk";
import { ParaEthersSigner } from "@getpara/ethers-v6-integration";
import { ethers } from "ethers";
import { useMemo } from "react";

export function useEthers(rpcUrl: string = "https://ethereum-sepolia-rpc.publicnode.com") {
  const para = useClient();
  const { isConnected, embedded } = useAccount();
  
  const clients = useMemo(() => {
    // Create a provider connected to your RPC endpoint
    const provider = new ethers.JsonRpcProvider(rpcUrl);
    
    // Check if Para is initialized and user has wallets
    if (!para || !isConnected || !embedded.wallets?.length) {
      return { provider, signer: null };
    }
    
    // Filter for EVM-compatible wallets
    const evmWallets = embedded.wallets.filter(w => w.type === "EVM");
    if (evmWallets.length === 0) {
      return { provider, signer: null };
    }
    
    // Create Para-enabled signer for transaction signing
    const signer = new ParaEthersSigner(para, provider);
    return { provider, signer };
  }, [para, isConnected, embedded.wallets, rpcUrl]);
  
  return clients;
}
