Connect to Airon Testnet

The Airon Testnet is a safe sandbox for building and testing smart contracts and dApps before launching to mainnet. Transactions use tAIR (test tokens with no monetary value), so you can iterate without financial risk.

Quick Start

Add the network to your wallet (MetaMask/WalletConnect).
Claim tAIR from the official faucet (see requirements below).
Send a test transaction or deploy a simple contract.
Inspect your tx on AironScan Testnet.

Network Parameters

Parameter

Value

Network Name

Airon Testnet

Native Symbol

tAIR

Chain ID

2030 (hex: 0x7EE)

RPC URL

https://rpc-testnet.airon.network

Block Explorer

https://testnet.aironscan.com

Some wallets request the Chain ID in hexadecimal. Use 0x7EE (which equals 2030).

Add Airon Testnet to Your Wallet

A) Manual (MetaMask & most wallets)

Open MetaMask → Settings → Networks → Add network (or Add network manually).
Enter the Network Parameters exactly as listed above.
Save and switch to Airon Testnet.

B) One-Click (from a website/dApp)

async function addAironTestnet() {
  if (!window.ethereum) return;
  try {
    await window.ethereum.request({
      method: "wallet_addEthereumChain",
      params: [{
        chainId: "0x7EE", // 2030
        chainName: "Airon Testnet",
        nativeCurrency: { name: "Test Airon", symbol: "tAIR", decimals: 18 },
        rpcUrls: ["https://rpc-testnet.airon.network"],
        blockExplorerUrls: ["https://testnet.aironscan.com"]
      }]
    });
  } catch (err) {
    console.error("Failed to add Airon Testnet:", err);
  }
}

async function switchToAiron() {
  if (!window.ethereum) return;
  try {
    await window.ethereum.request({
      method: "wallet_switchEthereumChain",
      params: [{ chainId: "0x7EE" }]
    });
  } catch {
    await addAironTestnet(); // if not added yet
  }
}

Get Test Tokens (tAIR) — Official Faucet

Faucet URL: https://drop-faucet.airon.network/

Claim steps (exact rules):

Connect Wallet.
Add Airon Testnet Network.
Requirement: Hold ≥ 1000 AIR COIN on the BNB Chain (in the same wallet).
Sign Ownership (message signature to verify you control the address).
Claim 1 tAIR.

Notes • If you don’t meet the requirement, the faucet will not dispense tAIR. • Make sure you are connected with the wallet that holds ≥ 1000 AIR COIN (BNB Chain). • After claiming, switch to Airon Testnet to see the updated tAIR balance.

Verify Your Connection

RPC health check (cURL):

curl -X POST https://rpc-testnet.airon.network \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

You should receive a hex block number (e.g., 0x123abc).

On the explorer: Open https://testnet.aironscan.com, paste your address, and confirm you can see your balance/transactions.

Developer Quickstart

Ethers.js

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider("https://rpc-testnet.airon.network");

(async () => {
  const [block, chainIdHex] = await Promise.all([
    provider.getBlockNumber(),
    provider.send("eth_chainId", [])
  ]);
  console.log("Chain ID:", parseInt(chainIdHex, 16)); // 2030
  console.log("Current block:", block);
})();

viem (and wagmi)

import { createPublicClient, http } from "viem";

export const aironTestnet = {
  id: 2030,
  name: "Airon Testnet",
  nativeCurrency: { name: "Test Airon", symbol: "tAIR", decimals: 18 },
  rpcUrls: { default: { http: ["https://rpc-testnet.airon.network"] } },
  blockExplorers: { default: { name: "AironScan", url: "https://testnet.aironscan.com" } },
};

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

(async () => {
  console.log("Block:", await client.getBlockNumber());
})();
