Arbitrum airdrop checker
Arbitrum One is a layer 2 network for Ethereum, and it uses the same 0x addresses. If you used Arbitrum, your address may have history there that you can't see on Ethereum mainnet. PoolIndex checks a public Arbitrum address for the ARB airdrop, protocol claims and coins left on the network.
You only paste the public 0x address. You can check a public address without connecting a wallet.
The ARB airdrop: allocation and claim status
The Arbitrum Foundation airdropped ARB to early users in March 2023. The claim deadline was September 24, 2023. After it passed, 69,448,385 unclaimed ARB were moved to the Arbitrum DAO treasury.
PoolIndex reads the official token distributor contract on Arbitrum One. It shows whether your address had an ARB allocation and whether it was claimed. The window is closed, so this is a record of what happened, not something you can claim now. That is still useful: it tells you whether to stop looking, and it helps you spot fake ARB claim pages, which keep appearing long after the deadline.
Radiant remediation on Arbitrum
After the October 2024 exploit of Radiant Capital, Radiant set up a remediation program for affected users. PoolIndex checks the official remediation contract on Arbitrum One for your address and shows the amount that is releasable to it, with a link to Radiant's remediation documentation.
The releasable amount can change over time, so PoolIndex shows it as of the time of the scan. As with any result, confirm on the official page before acting, and open it from Radiant's own documentation rather than from a link someone sends you.
Coins left on Arbitrum One
Bridged funds are easy to forget. PoolIndex checks ETH on Arbitrum One, the ARB, USDC, USDT and WETH tokens, and Aave v3 deposits of USDC and WETH on Arbitrum. Funds on Arbitrum stay on Arbitrum until you move them, and they don't appear in an Ethereum mainnet balance.
Aave deposits are a common example. A deposit made during an incentive program keeps its value in the aToken balance, even if you never open Aave again.
You can confirm any Arbitrum balance yourself on Arbiscan, the Arbitrum block explorer, by pasting the same public address.
Not sure you ever used Arbitrum?
Many people reached Arbitrum through a bridge or a DeFi app without thinking of it as a separate network. If you bridged ETH to save on fees in 2021 or 2022, used a decentralized exchange that offered an Arbitrum option, or received ARB in 2023, your address has Arbitrum history.
The quickest way to find out is to check. PoolIndex looks at the same 0x address on Arbitrum One and on the other supported networks in one scan, so you don't need to remember which networks you used. Each result names the network it came from.
Fees and safety on Arbitrum
Network fees on Arbitrum One are usually much lower than on Ethereum mainnet, but they are paid in ETH on Arbitrum, so you need a little ETH there to move anything. Never send coins to someone who promises to unlock an Arbitrum claim for you. The ARB airdrop window closed in 2023.

Frequently asked questions
- Can I still claim the Arbitrum airdrop?
- No. The ARB claim deadline was September 24, 2023, and the unclaimed ARB went to the Arbitrum DAO treasury. Any site offering an ARB airdrop claim today should be treated with suspicion.
- Why check the ARB airdrop if it has closed?
- It answers whether your address was eligible and whether it claimed, so you can stop wondering. It also helps you recognize fake claim pages.
- Do I need to connect a wallet?
- No. PoolIndex checks using your public wallet address only, the same address anyone can already see on the blockchain. It never asks for your seed phrase or private key.
- Is my Arbitrum address different from my Ethereum address?
- No. It is the same 0x address, but balances are separate. Coins on Arbitrum One don't show up on Ethereum mainnet.
- Do I need ETH on Arbitrum to check my address?
- No. The check reads public data and costs nothing. You need a little ETH on Arbitrum One only if you later want to move coins or tokens there.
- What is the Radiant remediation check?
- Radiant Capital set up a remediation program after its October 2024 exploit. PoolIndex checks the official contract for an amount releasable to your address and links to Radiant's documentation.
