Use Case

Airdrop Protection

Defend token distributions from Sybil farms

The problem

Airdrop farmers use hundreds of wallets across multiple devices to claim token distributions intended for genuine users. Traditional wallet-based eligibility checks can't detect when multiple wallets belong to the same person or device.

The solution

FingerprintIQ detects multi-wallet devices, clusters similar device fingerprints, and assigns Sybil risk scores. Identify when dozens of wallet addresses are being operated from the same physical device or device farm.

Code example

const result = await fiq.identify();
const walletCount = result.web3?.walletsDetected.length ?? 0;
const sybilScore = result.sybilRisk?.score ?? 0;

if (sybilScore > 0.8) {
  denyAirdropClaim("Sybil risk too high");
} else if (walletCount > 3) {
  flagForManualReview();
}
