Add to MetaMask

await window.ethereum.request({
  method: "wallet_addEthereumChain",
  params: [{
    chainId: "0x...",                        // hex of chainId
    chainName: "BiniChain",
    nativeCurrency: {
      name: "BINI",
      symbol: "BINI",
      decimals: 18,
    },
    rpcUrls: ["https://rpc.binibit.com"],
    blockExplorerUrls: ["https://scan.binibit.com"],
  }]
});

Once finalized, the chain will be addable via chainlist.org (community list) for easy click-to-add.

ethers.js

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider("https://rpc.binibit.com");
const network = await provider.getNetwork();
console.log("Connected to:", network.name, "chainId:", network.chainId);

viem

import { createPublicClient, http } from "viem";

const biniChain = {
  id: /* chainId */,
  name: "BiniChain",
  nativeCurrency: { name: "BINI", symbol: "BINI", decimals: 18 },
  rpcUrls: { default: { http: ["https://rpc.binibit.com"] } },
  blockExplorers: { default: { name: "Binibit Scan", url: "https://scan.binibit.com" } },
};

const client = createPublicClient({
  chain: biniChain,
  transport: http(),
});

Hardhat config

module.exports = {
  networks: {
    binichain: {
      url: "https://rpc.binibit.com",
      chainId: /* chainId */,
      accounts: [process.env.PRIVATE_KEY],
    },

Foundry config

Sandbox / testnet

During the sandbox phase, contracts have been deployed on Base Sepolia (chainId 84532) for development and testing. See BaiDEX → Contracts for testnet addresses.

The BiniChain mainnet RPC and chainId values will be published as part of the v2.x rollout.
