Proof-of-Compliance Passport

Institutional DeFi needs to know that a user is KYC’d, accredited, and in an allowed jurisdiction. Sending a passport to every protocol exposes the identity those checks were meant to protect.

A KYC provider issues a credential. The user generates ZK proofs: age over 18, KYC passed, jurisdiction allowed. Soroban verifies the proof before an RWA purchase, a private-credit pool, or payroll.

Stellar’s privacy direction is configurable, compliance-ready privacy, and native ZK verification primitives are available now.

A user proves they may buy a tokenized treasury. The pool contract checks the proof and opens the position. The passport never lands in the protocol’s storage.

   The gated action proceeds

• A credential issued by a known provider key.
• Three proofs: age, KYC, and an allowlisted jurisdiction.
• A verifier contract that accepts or rejects the proof.
• One gated action, such as an RWA purchase, that requires a valid proof.
• No raw identity fields in contract storage.

• Credential

  Commits to attributes signed by the KYC provider.

• Verifier

  Checks age, KYC, and jurisdiction proofs.

• Gate

  Refuses the protected call unless the verifier accepts.

• BN254 verification
• Poseidon commitments to credential attributes
• Compliance checks that do not store the underlying identity

• A KYC issuer
• An RWA purchase flow
• A compliant liquidity pool

1. 01

   Credential

   Provider signs a commitment to age band, KYC flag, and jurisdiction.

2. 02

3. 03

   Gate

   A purchase or deposit that reverts when verification fails.

   Demo

   Pass with an allowed jurisdiction. Fail with a blocked one. Show that storage has no passport data.

• Reuse one credential across RWA purchase, private credit, a compliant pool, and payroll.
