Use case — Regulatory Attribute Proof

LP Claim Attestation

Issue DeFi liquidity-provider attributes — KYC outcome, region, risk tolerance — as ZK attestations without exposing the raw data, so the protocol verifies only the attribute predicates it needs and meets regulatory requirements without ever holding the source identity record.

01 · WHO IT'S FOR

For DeFi protocol teams

Bound LP participation by eligibility without holding a custodial KYC database — resolving the binary between off-chain KYC cost and permissionless tail risk.

  • Protocol design leads building regulated DEXes, lending markets, or cross-border liquidity venues

  • Compliance and risk owners weighing privacy promises against AML / KYC obligations

  • Jurisdiction policy designers implementing region-based participation limits at the protocol layer

02 · THE SHIFT

Hand over the source, or just the facts?

Nothing changes on the floor. Everything changes for the receiver.

① Your team just saves, as always.

Why Lemma
  • The document stays private — the record itself is never sent or disclosed.
  • Independent verification — the receiver just opens a link. No account, no keys.
  • Edits are detected — even a one-character edit fails verification.

An LP completes identity verification with an issuer that already operates under a relevant regulatory regime — a regulated KYC provider, an attribute authority, a banking partner. The issuer signs a credential against the LP's identity record. The LP holds the credential in its own wallet.

When the LP deposits into a Lemma-integrated protocol, the deposit path verifies a ZK attestation against the credential: "this LP passed KYC with an issuer accepted by this protocol, is resident in a region permitted by this pool's policy, and falls into the risk tier this pool requires." Nothing else crosses to the protocol. The protocol never holds, indexes, or retains the identity record itself.

Revocation lives at the issuer. If the LP's KYC lapses or region changes, the issuer publishes an update and the next deposit path verification fails — without the protocol ever scanning its own LP set.

03 · HOW TO CHOOSE

Why the usual methods fall short.

Only work that needs all three at once — pass without exposing, independent verification, tamper-evidence — is Lemma's domain.

Method Pass without exposing Independent verification Tamper-evident What happens
Access control / permissions“Someone inside could have edited it” remains possible
Masking / redacted copiesRedaction work grows; the original is still unproven
Encrypt and store / sendTo verify, the receiver needs it disclosed after all
Lemma (ZK proof)the only one with all 3 The receiver just opens a link
