Web3 Signals

Prevent users from claiming multiple airdrop allocations by linking different wallet addresses to the same device fingerprint.

javascript
const result = await fiq.identify();
const wallets = result.signals.client.wallets;

// Same device claiming multiple airdrop wallets
if (result.visitCount > 3 && wallets?.multipleWallets) {
  // This device has visited multiple times with multiple wallets
  // Flag as potential Sybil before allowing airdrop claim
  await flagSybilRisk(result.visitorId);
  showChallenge();
}

Always verify the visitorId server-side before making airdrop decisions. Client-side checks alone can be bypassed.

Enforce one-device-one-vote to prevent governance manipulation by users running multiple wallet identities from a single machine.

javascript
const result = await fiq.identify();

// Check if this device has already voted
const hasVoted = await checkVoteStatus(result.visitorId);

if (hasVoted) {
  showMessage("This device has already cast a vote in this proposal.");
  return;
}

// Record the vote linked to this device fingerprint
await recordVote(result.visitorId, selectedOption);

Enforce per-device minting limits to prevent bots from minting out collections.

javascript
const result = await fiq.identify();

// Block obvious bots before any wallet interaction
if (result.botProbability > 0.5) {
  showCaptcha();
  return;
}

// Enforce device-level mint limit regardless of wallet address
const mintCount = await getDeviceMintCount(result.visitorId);
if (mintCount >= MAX_MINTS_PER_DEVICE) {
  showMessage("Mint limit reached for this device.");
  return;
}
