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, sealed under a Merkle root, and re-verifiable by anyone you hand it to, in a browser. No account. No PDF taken on faith.
Push-button for you; independently checkable by your exchanges, partners and examiners — and ready for your accounting firm's monthly examination.
The GENIUS Act (Pub. L. 119-27) requires every U.S. payment stablecoin issuer to publish monthly reserve disclosures, examined monthly by a registered public accounting firm and certified by the CEO and CFO. Final implementing rules land July 2026, and the Act takes effect no later than January 18, 2027 — sooner if the rules finalize first. The first mandatory disclosure cycles are months away, and a wave of new bank and fintech issuers will meet them for the first time. Every Tessera pack already maps its checks to the statute — 5/5 §4(a) checks passing in the current PYUSD pack.
We rebuild the coin's complete supply history from raw blockchain data — every mint, every burn, on every chain it lives on. Our independent count has matched the accounting firm's attested figure to within a fraction of a basis point.
The issuer's accounting firm publishes a monthly attestation of the reserves. We line those reserves up against the supply we counted — at the same instant — and flag anything that doesn't reconcile.
Every number links to its raw source file, each named by its SHA-256 fingerprint and all sealed under a single Merkle root. Your browser re-verifies the whole pack live; change one byte anywhere and it fails.
Tessera is compliance infrastructure, deliberately not an accounting firm. The GENIUS Act splits the monthly duty three ways, and each leg stays with its rightful owner:
Your monthly disclosure under §4(a)(1)(C) — total tokens outstanding and the amount and composition of reserves — generated, evidence-backed and sealed, every figure traced to its raw source file.
The §4(a)(3) monthly examination by a registered public accounting firm runs against a machine-verifiable evidence pack instead of weeks of spreadsheet back-and-forth.
Officer certification carries personal criminal liability for knowing falsehoods (18 U.S.C. §1350(c)). Sign over sealed evidence, not a spreadsheet you can't retrace.
Launching under the GENIUS Act? You shouldn't need to build a blockchain-forensics team to publish a compliant disclosure. The packs below are what Tessera produces from the outside, with no access at all — working with us takes it further:
Your GENIUS Act reserve disclosure generated from your published attestation and public chain data — every figure evidence-backed, sealed under a Merkle root, ready for your accounting firm's examination, and re-verifiable by anyone you hand it to.
Grant read-only connections to your custodians and banks and the evidence deepens: reserve holdings verified at the source, reconciled to the account level — a monthly close in hours, not weeks of back-and-forth.
Supply checked against reserves every day, exceptions flagged the day they appear, and a live “independently verified” page you can hand to exchanges, partners and regulators — instead of a monthly scramble.
Capability proof: both packs were built entirely from public data — neither issuer was asked for anything.
Supply independently reconstructed on all four chains it lives on — Ethereum, Solana, Arbitrum and Stellar.
Circle's attestation publishes totals only — no per-chain breakdown exists to corroborate, and the pack says so.
That's the point: anyone you hand a pack to can re-verify every number without trusting us — or anyone. Your disclosure inherits the same property.
One coin can live on many chains at once — PYUSD spans all four of these. A supply count that misses a chain isn't a count; that's why coverage is corroborated per chain, and the report says so when a chain can't be checked.
Tessera is built by a solo founder. Launching or running a stablecoin under the GENIUS Act? Your next monthly disclosure could look like the packs above — get in touch. Examiners and accounting firms: the same pipeline works as tooling under your engagement.
