Three-source verification method to lock down authenticity
All airdrops must pass the triple verification of official website + white paper + team background. Check whether the project's official website has SSL encryption enabled (the address bar shows 🔒), and compare the white paper's technical architecture to see if it plagiarizes known projects. Team members must have a LinkedIn profile, and the number of interactions on social accounts must exceed 5,000+/month, excluding "zombie accounts".
Screening for counter-common sense in profit models
Airdrops that promise "earning thousands of dollars a day at zero cost" and "guaranteed principal and high interest" are 100% scams. According to historical data, the median return of a single address for real airdrops is only 120-120-450, and on-chain interactions (such as cross-chain and staking) must be completed. Be wary of directly claiming the prize without on-chain records.
Permission isolation and on-chain sandbox testing
Use a dedicated wallet (such as Metamask sub-accounts) to participate in airdrops, check contract risks with Revoke.cash before authorizing, and refuse to grant 'unlimited transfer' permissions. Immediately transfer tokens to a cold wallet after receiving them to avoid asset retention.
Time-stamping anti-counterfeiting technology verification
Real project airdrops will submit smart contract code on GitHub 3-6 months in advance, and the snapshot time will be consistent with the block explorer records. If the token creation time is later than the claimed airdrop date, it is definitely a fake project.
Community traceability and on-chain tracking
After joining the project Discord, check if the administrator has enabled identity verification (blue ✅). Use Arkham to track the flow of airdropped tokens; if more than 50% is transferred to mixers or exchanges, sell immediately and report.
