ProofPass lets users prove eligibility for regulated financial products without revealing sensitive documents — using zero-knowledge proofs, verified on Stellar.
Every day, financial institutions ask people to hand over their most sensitive documents — not because they want them, but because regulation requires proof of eligibility. The result is a compliance process built on paperwork and centralized databases full of sensitive information that become an attractive target for breach.
Under SEC Regulation D, Rule 501(a), only accredited investors — those with a net worth exceeding $1,000,000, excluding the value of their primary residence — may access certain private investment products, including tokenized RWAs. This is a hard legal gate, not an optional check.
The settlement infrastructure exists. The compliant, privacy-preserving investor verification layer does not.
The circuit verifies a self-reported claim — inputs like kycPassed or sanctionsClear supplied directly by the user, with no external authority backing them.
Issued by a licensed professional and chained back to a publicly recognized certificate authority. We don't ask “do you say you're compliant.” We ask “can you prove a trusted third party already verified this” — and check the cryptographic math ourselves.
No documents change hands. No sensitive data is stored.
The document never leaves the user's device. There is no honeypot database to breach, subpoena, or leak.
Zero-knowledge from the ground up. The chain learns only one bit: this wallet qualifies. Nothing about who, how much, or from where.
Every authorization is backed by a Groth16 proof anyone can check on-chain — not a checkbox, not a trusted admin's word.
Authorization flows natively into the Stellar Asset Contract's trustline model — the settlement rail RWAs already run on.
“…excluding the value of their primary residence.”
SEC Rule 501(a) mandates this exact exclusion. Every legitimate CPA attestation letter must contain it — CPAs do not get creative with this language. That makes it a reliable, legally-mandated anchor for the proof circuit to target.

The accredited-investor gate is ProofPass's first implementation, not its ceiling. Proving a signed document satisfies a policy — without revealing it — generalizes anywhere a system asks for proof.
Nothing exotic. A proving stack the ZK community already trusts, settling on the network RWAs already use.
The internet was built around sharing documents. Regulated finance should be built around sharing proofs.
