Your monthly reserve disclosure,
with proof attached.
The GENIUS Act requires every U.S. stablecoin issuer to publish a monthly reserve disclosure. Tessera generates yours from raw blockchain data and your published attestation — every figure evidence-backed and re-verifiable by anyone, in a browser.
How it works
What Tessera does
Count every token
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.
Check it against the reserves
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.
Seal it so it can't quietly change
Every figure links to its raw source file, all sealed under one Merkle root. Change a byte anywhere and browser re-verification fails.
Why now — the GENIUS Act clock is running
The GENIUS Act (Pub. L. 119-27) requires every U.S. payment stablecoin issuer to publish monthly reserve disclosures.
Every Tessera pack already maps its checks to the statute — 5/5 §4(a) checks passing in the current PYUSD pack.
Built around the statute
Who does what — by design
The GENIUS Act splits the monthly duty three ways. Tessera is deliberately not an accounting firm — each leg stays with its rightful owner.
Prepares and proves
Your §4(a)(1)(C) disclosure — tokens outstanding, amount and composition of reserves — generated, evidence-backed and sealed.
Examines
The §4(a)(3) monthly examination runs against a machine-verifiable evidence pack instead of weeks of spreadsheet back-and-forth.
Certify
Certification carries personal criminal liability for knowing falsehoods (18 U.S.C. §1350(c)). Sign over sealed evidence, not a spreadsheet.
For issuers
Get your disclosure
Launching under the GENIUS Act? You shouldn't need a blockchain-forensics team to publish a compliant disclosure.
Your monthly disclosure, push-button
Generated from your published attestation and public chain data — sealed, re-verifiable, and ready for your accounting firm's examination.
Deeper proof, faster close
Read-only connections to your custodians and banks verify reserves at the source — a monthly close in hours, not weeks.
Continuous monitoring
Supply checked against reserves daily, exceptions flagged the day they appear, and a live page you can hand to exchanges and regulators.
Capability proof
Published evidence packs
Both packs were built entirely from public data — neither issuer was asked for anything.

Circle's attestation publishes totals only — 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.
Coverage
Chains covered today
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.
