TrustLayer is the decentralized human trust layer for Web3 — a Base-native protocol that publishes portable, sybil-resistant Trust Scores derived from peer vouches and on-chain proofs. Any dApp can verify a user is a real human in a single Solidity call, without KYC or biometrics.

Yes. Creating a Trust ID, vouching peers, and earning $TRUST rewards is free. Only optional premium tiers or write operations charge $TRUST fees.

Does TrustLayer require KYC or biometrics?

No. TrustLayer never collects KYC, iris scans, or personal data. Identity comes from peer vouches and wallet signatures — reputation is math, not documents.

What is the $TRUST token?

$TRUST is TrustLayer's native token on Base with a fixed 1B supply. It powers vouching rewards, badge fees, staking gates, and revenue-funded buyback-and-burn.

How does TrustLayer compare to Worldcoin?

TrustLayer requires no biometric hardware, is fully non-custodial, and lives on Base. Worldcoin uses iris scans and centralized orb hardware. See the full comparison at /vs/worldcoin.

How long does the Sybil-Proof Airdrops integration take?

Most teams ship a working integration in under a day using the TypeScript SDK and one Solidity view call.

Is any user PII collected?

No. TrustLayer is non-custodial and never collects biometrics, KYC, or personal data. Reputation is math anchored on Base.

What does it cost to integrate?

Reading Trust Scores from Solidity or REST is free. Only optional premium tiers or write operations charge $TRUST fees.

Sybil-Proof Airdrops

Stop airdrop farmers with a single Solidity call. TrustLayer verifies each claimer is a real, unique human — no KYC, no iris scan.

The problem

Airdrop farmers deploy thousands of wallets and steal >70% of most token launches. Traditional CAPTCHAs and KYC scare off real users and leak PII.

How TrustLayer solves it

Gate your claim contract behind a TrustLayer Trust Score threshold. One require() line filters out sybils, keeping the drop for real humans.

Key benefits

80%+ reduction in sybil claims proven across four testnet launches
Zero PII collected — no KYC, no biometrics, no data breach risk
One Solidity require() line — 12k gas per claim
Works retroactively via off-chain Merkle proofs
