The GENIUS Act requires every U.S. stablecoin issuer to publish a monthly reserve disclosure. Tessera does that work for you: supply rebuilt from raw blockchain data, reconciled against your reserves, delivered as a finished disclosure. Every figure is evidence-sealed and re-verifiable by anyone, in a browser.
How it works
No dashboard to operate, no team to hire. The pipeline does the work; anything that needs judgment surfaces as a flagged exception for review before you publish.
Every mint and burn on every chain the coin lives on, rebuilt from raw blockchain data. Our count has matched the attested figure to within a fraction of a basis point.
The reserves attested by the issuer's accounting firm, lined up against our count at the same instant. Anything that doesn't reconcile gets flagged.
Every figure links to its raw source file, all sealed under one Merkle root. Change a byte anywhere and browser re-verification fails.
The GENIUS Act (Pub. L. 119-27) requires every U.S. payment stablecoin issuer to publish monthly reserve disclosures.
Prescriptive rules are late; the statute isn't. Every Tessera pack already maps its checks to the statutory text: 5/5 §4(a) checks passing in the current PYUSD pack.
The work, demonstrated
Both packs were built entirely from public data. Neither issuer was asked for anything. This is what "we do the work" looks like with zero access. With your cooperation, it's your disclosure.
Supply independently reconstructed on all four chains it lives on: Ethereum, Solana, Arbitrum and Stellar.
Circle's attestation publishes totals only, so no per-chain breakdown exists to corroborate, and the pack says so.
Anyone you hand a pack to can re-verify every number without trusting us, or anyone. Your disclosure inherits the same property.
For issuers
Launching under the GENIUS Act? Don't build a reserve-reporting back office. We are one.
Prepared from your published attestation and public chain data: sealed, re-verifiable, and ready for your accounting firm's examination. You review the flagged exceptions and publish; we do the rest.
Read-only connections to your custodians and banks verify reserves at the source, for a monthly close in hours instead of weeks.
Supply checked against reserves daily, exceptions flagged the day they appear, and a live page you can hand to exchanges and regulators. When weekly regulatory reporting arrives, the same pipeline already runs daily.
Built around the statute
The statute mandates two signatures: your accounting firm's examination opinion and your officers' certification. Everything underneath those signatures is labor, and Tessera does it. We are deliberately not an accounting firm; each signature stays with its rightful owner.
Your §4(a)(1)(C) disclosure: tokens outstanding plus the amount and composition of reserves, prepared, reconciled, evidence-backed and sealed.
The §4(a)(3) monthly examination runs against a machine-verifiable evidence pack instead of weeks of spreadsheet back-and-forth.
Certification carries personal criminal liability for knowing falsehoods (18 U.S.C. §1350(c)). Sign over sealed evidence, not a spreadsheet.
Coverage
Supply independently rebuilt on every chain PYUSD lives on.
One coin can live on many chains at once; PYUSD spans all four. Coverage is corroborated per chain, and the report says so when a chain can't be checked.
