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.

Do I need an API key for the badge?

No. Public profile badges are open and cached at the edge.

Will it slow my page down?

The SVG is a few kilobytes and edge-cached; the iframe loads lazily.

Yes — build your own markup from the verify endpoint if you need full control of the design.

How to add a live trust badge to your site

You want visible proof of reputation on a page, not just a number in your database.

The problem

A score buried in your backend changes nothing about how buyers behave. A visible, verifiable badge that a visitor can click and check does.

Step by step

1. Drop in the SVG badge

Fully static, cacheable, works in READMEs, emails and server-rendered HTML.

<a href="https://trstlyr.com/u/tawhid">
  <img src="https://trstlyr.com/badge/tawhid.svg" alt="TrustLayer verified score" height="28" />
</a>

2. Or embed the live card

The iframe card shows score, tier and vouch count and refreshes itself.

<iframe src="https://trstlyr.com/embed/tawhid" width="360" height="120"
  style="border:0" loading="lazy" title="TrustLayer profile"></iframe>

3. Keep the link
Badges must stay clickable through to the public profile so any visitor can verify the claim independently. That link is the whole point of a portable badge.

Share the proof

Once you are live, show it. This badge stays up to date on its own and links visitors back to the verifiable profile behind the score.
