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.

Soul-Bound Token (SBT)

A Soul-Bound Token is an NFT that cannot be sold or transferred. TrustLayer issues SBTs for badges, vouches, and streak milestones so reputation cannot be bought.

SBTs (ERC-5192) are the natural container for reputation. TrustLayer mints SBTs for Blue Badges, vouch counts, and streak milestones. Because they are non-transferable, they represent achievement rather than wealth.

Blue Badge

The Blue Badge is a soul-bound NFT on Base awarded to Trust IDs with a Trust Score above the verification threshold — a cryptographic blue checkmark.

Trust Score

Trust Score is a 0–1000 number computed from peer vouches, streaks, and on-chain activity — a portable reputation metric anchored to your wallet on Base.
