Find Forgotten Tokens and Airdrops
Most wallets only show the network you last selected, so tokens from old airdrops, bridges and experiments can sit unnoticed for years. Here is how to look properly, and safely.

Why forgotten tokens happen
One address works on many networks, but each network keeps its own balances. If your wallet is set to Ethereum, assets on Base, Arbitrum, Optimism, Polygon, BNB Smart Chain or Avalanche are not in view unless you switch. Airdrops, quest rewards and one-off bridges all leave small balances behind.
Step 1: list your addresses
- Current wallets and old browser-extension wallets.
- Addresses you used for a single mint, quest or airdrop.
- Withdrawal addresses saved in exchange accounts.
Step 2: scan every network, read-only
Use a multi-chain scanner that only needs your public address. Dust Finder currently reads seven networks: Ethereum, BNB Smart Chain, Polygon, Arbitrum, Base, Optimism and Avalanche. No scanner covers every chain, so also check others you remember using in a block explorer.
Step 3: verify before you touch anything
- Compare each token contract with the project’s official channels.
- Check liquidity before trusting a displayed price. An illiquid token may not be sellable at that price.
- Treat unsolicited tokens that push you toward a link as untrusted.
A note on “claim” pages
Real airdrops are announced through a project’s official channels. A token in your wallet that tells you to visit a site is far more likely to be bait than a reward. Never sign an approval you do not understand to “claim” something.
Frequently asked questions
How do I find old airdrops I forgot?
Scan each of your addresses on every network you have used, then verify each unfamiliar token before deciding what to do.
Are forgotten tokens usually valuable?
Often they are small or illiquid. A few can be worth more than expected, which is why checking is worthwhile, but do not assume a displayed price is realisable.
Is it safe to paste my address into a scanner?
Yes, if the tool is read-only. Never share a seed phrase or private key.
Dust Sweeper is a non-custodial tool: it reads your public address and every swap or bridge is a transaction you review and sign yourself. It never needs your seed phrase.
