Find unclaimed airdrops in an old crypto wallet
Many people set up a crypto wallet years ago, tried a few apps and then forgot about it. Some of those apps later gave coins or tokens to their early users. If nobody claimed them, they are unclaimed airdrops: allocations that exist on a public list but never reached the wallet.
This page explains why airdrops go unclaimed, what usually happens to them, and how to check an old wallet address with PoolIndex on Windows or Android.
Why airdrops go unclaimed
Most airdrops are not sent to you automatically. The project publishes who is eligible, and each person has to visit the claim page and send a claim transaction. That extra step is where many allocations get lost.
- The owner never heard about the airdrop, or heard about it after the window closed.
- The wallet was set up on an old phone or computer and forgotten.
- The network fee to claim looked higher than the value of the coins at the time.
- The owner was not sure the claim page was real, and decided not to risk it.
What happens to unclaimed airdrops
It depends on the program. Some airdrops have no deadline. Uniswap's 2020 UNI airdrop gave 400 UNI to each eligible address, and millions of UNI from it are still waiting in the official distributor contract.
Other programs set a deadline and then moved what was left. When the ENS claim window closed in May 2022, 5,375,000 unclaimed ENS were swept back to the ENS DAO treasury. After the Arbitrum claim deadline in September 2023, 69,448,385 unclaimed ARB were moved to the Arbitrum DAO treasury.
So an unclaimed allocation is not always still available. A good check tells you both things: whether the address had an allocation, and whether the program is still open.
What can still be waiting in an old wallet
Besides airdrops, old wallets often hold things their owners forgot: a deposit in Aave or Compound, shares in a Yearn vault, rewards in Curve or Convex, a Uniswap liquidity position, or staked ETH waiting in a Lido withdrawal. Some tokens also have official upgrade paths, such as MKR to SKY.
One public 0x address is checked on Ethereum, Arbitrum One, Optimism, Base and Polygon, plus specific programs on Sonic and Fantom Opera.
Find your old wallet's public address
You need the wallet's public address, the long string that starts with 0x. In MetaMask, Trust Wallet or Coinbase Wallet it is shown under Receive or at the top of the account screen, with a copy button. The public address is safe to look up: it is already visible to anyone on the blockchain.
If you used an exchange app such as a trading platform, the deposit address there is usually managed by the exchange. Results for that address may not apply to you, so check the exchange's official help pages instead.
Never type the wallet's seed phrase (recovery words) or private key anywhere to check for airdrops. A real check only needs the public address.

Frequently asked questions
- Can I still claim an airdrop from years ago?
- Sometimes. Programs without a deadline, such as the 2020 UNI airdrop, can still be claimed by eligible addresses. Programs with a deadline, such as ENS and Arbitrum, cannot. PoolIndex shows which case applies.
- How do I know if my old wallet has unclaimed airdrops?
- Check its public address against the official airdrop lists and claim contracts. PoolIndex does this for the programs it supports, and each airdrop result links to its official source.
- 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.
- I lost my seed phrase. Can PoolIndex help me get into the wallet?
- No. PoolIndex is not a recovery service and never asks for a seed phrase or private key. Without the recovery words, nobody can move coins from that wallet, including you.
- Someone says they can recover my unclaimed airdrop for a fee. Is that real?
- Treat it as a scam. Nobody can claim an allocation for you without your wallet's keys, and nobody can reopen a program that has closed. Never pay or share your seed phrase to unlock an airdrop.
- Is a claim fee worth paying?
- Only you can decide. Claiming costs a network fee. On Ethereum mainnet the fee can be larger than a small allocation, so compare the two before you claim.
