Prerequisites

Before integrating Para with Arc Chain, ensure you have:
  • A Para API key from the Para Developer Portal
  • Node.js 18+ and Next.js development environment
  • Basic familiarity with React and TypeScript

​
Installation

npm install @getpara/react-sdk Please make sure to be on version 2.2.0

​
Setup Para Provider

Create a ParaSDKProvider that communicates with Arc Chain.
from "@para/sdk-react";

const ARC_TESTNET = {
  name: "Arc Testnet",
  evmChainId: "5042002" as const,
  nativeTokenSymbol: "USDC",
  logoUrl:
    "<YOUR_ARC_LOGO_URL>", // Replace with your Arc logo URL
  rpcUrl: "https://rpc.testnet.arc.network",
  explorer: {
    name: "ArcScan Testnet Explorer",
    url: "https://testnet.arcscan.app",
    txUrlFormat:
      "https://testnet.arcscan.app/tx/{HASH}",
  },
  isTestnet: true,
};

export function ParaProvider({ children }: { children: React.ReactNode }) {
  return (
    <ParaSDKProvider

Key Features

This integration provides a way to use Para Wallet with Arc Chain, an EVM-compatible L1 blockchain that uses USDC as its native gas token for predictable fiat-based transaction fees. Arc features sub-second deterministic finality and is designed for programmable money, lending, capital markets, FX, and payments.
