Manual Configuration

{
  "chainName": "BrainArk Blockchain",
  "chainId": "0x4D4",
  "nativeCurrency": {
    "name": "BAK",
    "symbol": "BAK",
    "decimals": 18
  },
  "rpcUrls": ["https://rpc.brainark.online"],
  "blockExplorerUrls": ["https://explorer.brainark.online"]
}

Add via JavaScript (ethers.js)

await window.ethereum.request({
  method: "wallet_addEthereumChain",
  params: [{
    chainId: "0x4D4",
    chainName: "BrainArk Blockchain",
    nativeCurrency: { name: "BAK", symbol: "BAK", decimals: 18 },
    rpcUrls: ["https://rpc.brainark.online"],
    blockExplorerUrls: ["https://explorer.brainark.online"]
  }]
});

Add via viem / wagmi

import { defineChain } from "viem";

export const brainarkChain = defineChain({
  id: 1236,
  name: "BrainArk Blockchain",
  nativeCurrency: { name: "BAK", symbol: "BAK", decimals: 18 },
  rpcUrls: {
    default: { http: ["https://rpc.brainark.online"] }
  },
  blockExplorers: {
    default: { name: "BrainArk Explorer", url: "https://explorer.brainark.online" }
  }
});

Connect with ethers.js

const { ethers } = require("ethers");

const provider = new ethers.JsonRpcProvider("https://rpc.brainark.online");

// Verify connection
const network = await provider.getNetwork();
console.log(network.chainId); // 1236n

// Get BAK balance (BAK is native coin — use getBalance, NOT balanceOf)
const balance = await provider.getBalance("0xYourAddress");
console.log(ethers.formatEther(balance), "BAK");

Connect with viem

import { createPublicClient, http, formatEther } from "viem";
import { brainarkChain } from "./chain";

const client = createPublicClient({
  chain: brainarkChain,
  transport: http("https://rpc.brainark.online")
});

// Get BAK balance
const balance = await client.getBalance({ address: "0xYourAddress" });
console.log(formatEther(balance), "BAK");

Important Notes

• BAK is the native coin (like ETH on Ethereum). Use provider.getBalance(), not balanceOf().
• For payable contract calls, send BAK as { value: amount }.
• The chain uses IBFT 2.0 consensus — fast finality, ~2 second block times.
• Gas price: 1000 wei (very low fees by design).
