Verifiable identity and age checks for decentralized platforms

Compliant age and identity verification for Web3. Privacy-first. Human-led. Network-ready.

Age Layer helps crypto, DeFi, NFT and metaverse platforms onboard verified users — without compromising decentralisation or UX.

Why It Matters

In Web3, you’re accountable to regulators — from AML and KYC to evolving age assurance laws — while also serving privacy-conscious users who reject traditional identity methods.

Yoti is used by platforms like Cryptograph to verify high-value buyers in blockchain settings Yoti+3Yoti+3Yoti+3altme.io.

Our goal: offer similar compliance-grade verification, but built for decentralised identity, not centralised silos.

How Age Layer Works For Crypto & Web3

1

User completes human-reviewed verification

Government-issued ID + selfie (redacted fields supported)

Selfie-only fallback or liveness video if needed

Human specialists validate authenticity, age, and document integrity

2

Issue a signed trust token or passcode

Confirms user meets your criteria (e.g. 18+, residency, identity)

No personal data—only the fact of verification

3

Users share tokens off-chain / on-chain

Integrate into wallet or credential systems

Optional compatibility with SSI wallets (like Altme), enabling age proof without sharing identity YotiYoti+2altme.io+2Yoti+2altme.io+1altme.io+1

4

Apply scoped access or transaction rules

Ratify high-value bids, whitelist users, or prevent access to minors

Real-time logic plus fallback to manual review if uncertain

Use Cases & Industry Scenarios

Crypto marketplaces & NFT auctions

DeFi onboarding

Allow verified users to participate in token sales, lending pools, or staking, while keeping their data off-blockchain.

Metaverse & virtual worlds

Provide age-appropriate visual experiences or restricted content within virtual spaces.

Guilds, DAOs & private servers

Gate membership—for example, only allow access to verified adult users in a Discord channel.

Gaming & Esports platforms

Use age tokens to validate eligibility for tournaments or age-restricted content in Web3 games.
