For IDV Providers
Enforcement after
identity verification.
Lemma.id turns a completed identity verification into a reusable, site-scoped enforcement credential.
Today, Lemma.id uses an upstream IDV provider to run live document and liveness checks. After verification, Lemma.id derives a privacy-preserving person root and issues site-private credentials that relying sites can verify locally.
Lemma.id currently uses Didit as its upstream IDV provider.
The IDV provider handles the check.
Lemma.id handles enforcement.
The IDV provider handles the identity check. Lemma.id handles credential issuance, site-scoped PPIDs, local verification, and abuse enforcement.
Lemma.id is not a replacement for IDV. It is an enforcement layer after IDV.
We are interested in working with IDV providers who want their verification events to power reusable, privacy-preserving enforcement across fraud-heavy consumer flows such as ticketing, marketplaces, rewards, gaming, and account abuse prevention.
Why this matters for IDV providers
A new category of IDV demand, structurally non-competing
Most websites — waitlists, free-trial SaaS, ticketing, comments, dating, AI agent gating — never buy IDV because $1–2 per user can't be justified per signup. Lemma pools demand across many sites so a single issuance funds verification across the network.
Net-new verification volume
Long-tail sites won't pay $1–2 per user for full IDV. Pooled across the network, they will pay a few cents per check. They adopt because Lemma lets them act on a verified-human signal without storing ID documents or running their own KYC stack.
You keep the upsell
Lemma never participates in expansion revenue. The relying-site relationship belongs to the IDV provider; full IDV, age, KYB, AML, monitoring, manual review — all sold direct, full margin.
Recurring revenue via revocation
Sites can challenge a credential at any time. Refresh and step-up checks generate a long tail of issuance events from a single onboarding — converting one-shot KYC into a continuously-priced trust signal.
Designed not to disintermediate providers
lemma.id's local-first design is built so it does not need cross-site behavioral data to deliver value. IDV providers keep the verification relationship, pricing power, and upsell path for higher-assurance checks.
How it works
Verify once. Carry the credential. Enforce locally.
A user completes live IDV through Lemma.id's hosted flow. Lemma.id issues a signed credential to the user's wallet. Relying sites verify it locally — no round-trip to the IDV provider or to Lemma for routine access decisions.
Site triggers verify
Relying site embeds the SDK; user has no credential yet.
Live IDV runs
Lemma.id hosts wallet unlock and upstream document + liveness checks.
Lemma.id issues credential
Ed25519-signed credential with site-scoped PPIDs derived from a privacy-preserving person root.
Wallet stores it locally
Credential lives in the user's browser wallet, not on Lemma servers.
Sites verify locally
Future sites validate signature + freshness in-browser, no round-trip required.
Like a physical driver's license. The DMV signs once. The bar verifies locally. The DMV doesn't get notified at the moment of use. Lemma works the same way — credentials are issued after IDV, sites verify locally, users carry the credential.
Architecture
Designed not to disintermediate IDV providers
lemma.id does not need to observe cross-site usage to deliver value. Credentials live in the user's browser, verification happens in-browser, and routine access decisions do not require a live callback to the IDV provider. Providers keep the verification relationship, pricing power, and upsell path for higher-assurance checks.
The architecture is designed to complement IDV provider distribution — not replace it.
