Airdrop and referral abuse prevention for crypto
Token rewards, sign-up bonuses and referral payouts attract one person running hundreds of accounts. FingerPrint Checker adds a device and household limit at the moment of the claim, in your web app and in your mobile app.
Abuse patterns we see in this industry
- Sybil accounts created to collect a sign-up or airdrop reward.
- Referral payouts to the referrer’s own accounts.
- Scripted claims across many wallets.
How FingerPrint Checker maps to them
We look at the device and network of the claimant. We do not analyse wallets or on-chain activity.
- Multi-accounting: one claim per device and household.
- Coupon and referral abuse: relation checks for referral rewards.
- Bot detection: human checks and automation flags on new devices.
What it does not do
FingerPrint Checker is a device and household signal that decides whether one device may claim one thing. It is not identity verification, and it does not replace the checks your regulator or payment provider requires.
Frequently asked questions
Does it work for anonymous sign-ups without email?
Device limits and quotas work without an email. Eligibility claims use the email when you have one.
