Noirpay
Compliance and security

Compliance is built in, not bolted on

Sanctions screening on entry and exit, association-set proofs so clean users can show they aren't in a tainted pool, and expiring disclosure keys for auditors. That is the difference between a product card issuers will underwrite and one they won't.

DISCLOSURE
0
Permanent viewing keys. Every key is scoped by you and expires
At the edge

Screened on the way in and on the way out

Privacy inside the pool, checks at its boundary. The pool stays clean because nothing sanctioned gets in, and clean users can prove it.

Edge compliance screening

Sanctions screening on every shield and unshield, plus association-set proofs that demonstrate pool hygiene.

Fiat ramps with identity separation

Licensed on- and off-ramps. KYC records never link to on-chain activity.

Time-decorrelated withdrawals

Exits are scheduled and split, so an unshield can't be matched to a shield by timing.

Disclosure

Show exactly what's needed, to exactly who needs it, for exactly as long

A viewing key is read-only, scoped to a date range, and revocable. Set an expiry and it revokes itself.

Scoped viewing keys

Read-only access to a specific date range, for an accountant, auditor or lender. Revoke it whenever you like.

Programmable disclosure expiry

Set an expiry and the viewing key revokes itself. No key lives forever.

Encrypted transaction memos

Private bookkeeping labels, readable only by you or a viewing-key holder.

Private tax and accounting export

CSV or PDF, generated locally from a viewing key. Nothing leaves your machine.

Attestations

Prove it without revealing it

Zero-knowledge proofs answer yes-or-no questions about a shielded balance. Balance above X. Held N months. Not in a tainted set. The account itself stays closed.

Zero-knowledge proof of funds

Prove a balance above X, or that you held a position for N months, without revealing the account.

Collateral attestation

A lender accepts a proof of shielded holdings instead of watching a public wallet.

Corporate actions for tokenized stocks

Dividends and splits are credited to shielded holders without revealing who holds what.

Who you can prove things to

Every party that used to need your whole wallet gets a narrower answer

Security

Self-custodial from the first note

Your spending key is yours. Noirpay runs the pool and the proofs, not your money.

Social recovery

Guardians, passkeys and hardware wallets. A lost device isn't a lost account.

Client-side portfolio dashboard

Your portfolio decrypts locally in the browser. The server never sees your positions.

Card and device controls

Per-card and per-device spending limits, freeze, and an instant kill switch.

Shielded treasury multi-sig

Co-signers on the treasury, for companies that can't put funds behind a single key.

Automatic note consolidation

Your encrypted notes are defragmented in the background, so proofs stay fast and fees stay low.

Gas sponsorship

A paymaster pays the gas. You never hold the chain's gas token.

What Noirpay never sees

Three things we designed ourselves out of

01

Your positions

Notes decrypt in your browser. The dashboard, the statements and the tax export are all generated locally.

02

Your KYC record next to your chain activity

Identity checks live with the licensed ramp. Noirpay never holds both halves of that link.

03

A permanent back door

There is no master viewing key. Every disclosure is scoped, time-boxed and issued by you.

Privacy your accountant, your lender and your card issuer can all live with
