Verify the portal (domain + official sources)
Use official Arbitrum channels to find the correct claim page. Avoid ads and lookalike domains.
This is a practical, security-first guide to Arbitrum Airdrop: how to check eligibility, how to claim safely (without approvals traps), what to verify on explorers, how to avoid fake claim portals, and how to troubleshoot the most common “eligible but can’t claim / tokens not showing / wrong chain” cases.
Use official Arbitrum channels to find the correct claim page. Avoid ads and lookalike domains.
Eligibility checks should be read-only. Don’t sign approvals just to “check”.
Airdrop claims usually require a claim transaction, not unlimited token approvals. Confirm what you’re signing.
Verify the claim on an explorer, then revoke suspicious approvals and consider wallet segmentation.
An Arbitrum airdrop claim typically means an allocation is determined off-chain (snapshots/criteria), and the claim is executed on-chain via a claim contract. The safest workflow is to verify the claim contract and portal, keep permissions minimal, and confirm outcomes on an explorer.
A read-only eligibility check + a single claim transaction + explorer confirmation.
“Connect wallet → approve unlimited → sign permit → claim” on a lookalike domain.
Verify tx status, token transfer logs, and contract addresses.

| Scam pattern | What it tries to do | Defense |
|---|---|---|
| Lookalike claim site | Steal approvals / signatures | Use official sources + bookmarks |
| “Approve to claim” | Get unlimited allowance | Never approve for eligibility checks |
| Permit / signature trap | Drain without on-chain approve | Read signature request carefully |
| DM / support impersonation | Get seed phrase / remote control | No legit support asks for keys |
Airdrops can create taxable events depending on your jurisdiction. Keep clean records so you can reconcile later: claim time, tx hash, token amount, and token price reference.
Unique, reputable references for airdrop verification, token identity checks, and security hygiene:
Use official Arbitrum sources to find the eligibility checker, confirm the domain, and perform a read-only check. You should not need to approve tokens or sign “permit” messages just to check eligibility.
Verify the claim portal via official sources, verify the claim contract on an explorer, submit the claim transaction, then confirm success on the explorer. Avoid unlimited approvals and suspicious signature prompts.
Airdrops attract high-intent traffic. Fake sites aim to trick users into approving unlimited allowances or signing malicious permits. Always verify domains and contracts.
First verify on an explorer that the claim succeeded and token transfer event exists. Then switch wallet to the correct network, refresh, and add the token manually only using the verified contract address.
Usually no. Airdrop claims commonly involve a claim transaction, not token approvals. If a site demands approvals to “claim”, treat it as suspicious.
Save the tx hash, claim timestamp, amount received, and a public price reference at claim time (e.g., CoinGecko/CoinMarketCap). Rules depend on your jurisdiction.
Use an allowance tool like Revoke.cash while connected to the correct network and revoke approvals you don’t need anymore. This reduces risk if you interacted with a questionable contract.
Start from official sources and use bookmarks. If you arrived via ads/DMs, assume it’s a scam until verified.
