Reserve Attestation · GENIUS Act · AICPA AT-C 205

Your blockchain data,
demystified.

The GENIUS Act requires monthly CPA-attested proof that your reserves cover circulation. Blockchain data and CPAs don't speak the same language, so we translate.

The Problem

The compliance gap
this mandate created.

The blockchain data exists. The CPAs exist. The legal mandate exists. What's missing is the infrastructure between them.

01
Blockchain data is formatted for computers to read, not a CPA to review.
Raw on-chain records need translation into a structured, auditable format before any accountant can work with them.
02
CPAs aren't blockchain specialists.
A qualified CPA can attest to reserve adequacy, but only if the data is presented correctly. That handoff doesn't happen automatically.
03
The compliance infrastructure doesn't exist yet.
This is a new mandate with no off-the-shelf solution. Building it from scratch takes time most issuers don't have before the deadline.
What We Do

You no longer have to handle your data
and your CPA.

We pull your on-chain data, reconcile it against your reserve balance, and produce a structured package your CPA can verify and sign.

We specialize in one thing: making blockchain data readable and defensible for CPA attestation under AICPA AT-C Section 205.

You get a signed monthly attestation package. Your regulator accepts it. Your board trusts it.

On-chain mint and burn records, every transaction, every chain

Your finance contact signs a monthly reserve confirmation on our template. One document. We handle the rest.

We build the package.
Reconciliation, variance classification, and a report formatted to AICPA AT-C Section 205. Your CPA receives everything they need to verify and sign.
04
Your CPA signs. You stay compliant.
Signed attestation delivered every reporting period. GENIUS Act requirement met. No internal compliance team needed.
Regulatory Context

The mandate is real.
The deadline is coming.

The GENIUS Act requires monthly reserve attestation from every U.S. stablecoin issuer. The OCC filed proposed rulemaking in April 2026. Implementation expected late 2026.

The Requirement
Monthly CPA-attested proof
Every regulated stablecoin issuer must produce monthly proof that reserves equal or exceed circulation. This is a condition of operating.
The Standard
AICPA AT-C Section 205
All deliverables are formatted to this standard. Your CPA's signature carries weight because the package is built correctly.
The Timeline
Late 2026 implementation
OCC, FDIC, and NCUA have all issued proposed rules. Build the infrastructure now. Don't scramble later.
