These measures can all be valid and still show different numbers. Record the definition, token contract, chain coverage, exclusions and timestamp beside every figure you use.
Choose the measure that answers your question
“Supply,” “outstanding” and “circulating” are not universal labels. A supply figure is useful only when you know which tokens it counts and what question it is intended to answer.

| Measure | What it tells you | Important limit |
|---|---|---|
| Issuer-reported circulation | The issuer’s reported quantity under its own definition and reporting period. | May include balances held by the issuer’s corporate group and exclude other categories; it is not automatically a count of freely transferable tokens. |
| On-chain total supply | Tokens outstanding on a particular chain and token contract at a point in time. | Does not, by itself, establish whether tokens have reached users or are available in secondary markets. |
| Provider-estimated circulating supply | A market-data provider’s estimate after applying its classification rules. | Provider exclusions and chain coverage can differ, so figures may not be directly comparable. |
| Net issuance toward secondary markets | An estimate of net new funds moving from primary issuance toward secondary-market use, using issuance and issuer-wallet flows. | It is a flow-based estimate, not a direct count of all tokens held by users or available to trade. |
| Regulatory outstanding issuance value | A legal or reporting measure defined for a particular regulatory purpose. | Its scope is not automatically the same as a market-data provider’s circulating-supply methodology. |
How to track a stablecoin, step by step
- State the question. For issuer obligations or redemption claims, begin with the issuer’s circulation and reserve disclosures. For token creation on one network, examine the relevant contract’s supply changes. For a provider-to-provider comparison, read each provider’s methodology first.
- Identify the asset precisely. Record the stablecoin name, token contract address and blockchain. The same name on two chains does not establish that the tokens are interchangeable or represent the same ledger balance.
- Choose the time basis. Mark whether the figure is a point-in-time balance, a reporting-period-end balance, an average over a period, or a flow over a period. Do not compare an average or a flow with a point-in-time balance as though they measured the same thing.
- Inspect the relevant records. For an issuer measure, use the issuer’s stated definition and reporting period. For chain-level supply, use data for the identified contract and chain, distinguishing mints from burns. For a provider estimate, check its stated exclusions and which tokens and networks it covers.
- Check wallet and token treatment. Determine how the source handles issuer treasury, corporate, restricted, locked, bridged, wrapped, inaccessible and pending-burn balances. If the source does not explain a category relevant to your comparison, mark that treatment as unknown rather than assuming it is included or excluded.
- Save provenance with the number. Keep the source, retrieval time, reporting date or block height, unit and definition alongside the value. This makes a later change traceable and prevents a chart from silently mixing different measures.
Why USDC supply figures can differ
Issuer reporting uses an issuer-defined population
Circle’s Form 10-Q for the quarter ended June 30, 2026 defines “USDC in circulation, end of period” as “the total amount of USDC minted and outstanding as of the end of the reporting period.” The filing also describes a simple daily-average measure, which is not interchangeable with the period-end balance. Circle’s platform-breadth metric excludes pending burns and access-denied USDC but includes corporate-held USDC. Those classifications describe Circle’s reporting choices; they are not a universal definition of freely transferable circulation.
Blockchain supply records issuance on the observed chain
A contract’s total-supply changes show additions through mints and subtractions through burns on that chain. As the Federal Reserve Board’s February 23, 2024 study, Primary and Secondary Markets for Stablecoins, puts it: “Minting and burning of tokens simply describes the addition or subtraction of tokens to the total supply on Ethereum.” That study analyzes Ethereum; a single-chain figure should not be presented as the stablecoin’s complete global supply.

Provider estimates apply classification rules
CoinGecko’s general supply methodology excludes certain locked, vested, escrowed, treasury and stakeholder-held balances from its circulating-supply estimates. Other services may draw the boundary differently. Before comparing market-cap figures, check each provider’s methodology and the exact token and chain coverage used for the asset.
Issuer-wallet flows help distinguish issuance from market entry
A mint can increase on-chain supply even if the newly created tokens remain in an issuer-controlled treasury. The Federal Reserve researchers describe estimating net new funds moving from primary issuance to secondary markets by subtracting net transfers into treasury wallets from net on-chain mints. This is one analytical method, not a uniquely authoritative or universally adopted measure; its result depends on identifying the relevant treasury wallets and period.

Tracking circulation across multiple chains
Build the total from chain-level records rather than adding every similarly named token balance you find. Native issuance can occur on multiple networks, while bridged or wrapped representations may be backed by tokens elsewhere. Adding both a representation and its backing tokens without accounting for the relationship can double-count economic exposure. Conversely, a single-chain total can miss native issuance on other networks.
Recommended Free Tools
The Bank for International Settlements’ Annual Economic Report 2026 describes tokens on separate chains as residing on separate ledgers without native communication between them. For a multi-chain view, state which contracts and chains are included and how you treat bridge escrow, wrapped representations, issuer treasuries and pending burns. If those details cannot be established, report the chain figures separately rather than presenting an unsupported global total.

Use a consistent record when comparing numbers
A tracking row should preserve enough information to reproduce the comparison. Record:
- Stablecoin name, contract address and chain.
- Measure name and the source’s exact definition.
- Publisher or issuer and the source document or methodology.
- Reporting date or block height, plus the retrieval timestamp.
- Units and currency, and whether the value is a balance, average or period flow.
- Treatment of issuer treasury, corporate, restricted, locked, bridged, wrapped, inaccessible and pending-burn balances.
When two figures disagree, compare their population, ledger coverage, wallet treatment, time basis and purpose. That usually identifies whether the difference reflects definitions rather than an error. Do not infer that a larger circulation number means stronger backing or greater usage: those are separate questions.

Regulatory figures are a separate category
On September 29, 2026, the Federal Reserve Board issued a proposal defining outstanding issuance value for a regulatory purpose. The proposal generally focuses on payment stablecoins subject to an issuer’s obligation to redeem or repurchase them at a fixed monetary value. It would remove permanently burned tokens, retain certain legally restricted tokens where the obligation continues, and exclude repurchased tokens held in issuer inventory until they return to circulation. The proposed rule says the measure generally includes “the issued payment stablecoins in circulation.” This is proposed regulation, not a settled market-wide analytics standard.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The FDIC’s 2026 proposed reporting approach likewise describes monthly disclosures of outstanding payment stablecoins and reserve composition using the prior month-end as the reporting date, with independent examination and CEO/CFO certification described in the proposal. Treat these as proposed requirements, not as evidence that every stablecoin issuer currently reports under one common framework.

Keep market-wide totals dated
Aggregate market capitalization is a dated snapshot, not a stablecoin supply definition that can be reused without its date. The Federal Reserve Board’s April 8, 2026 note, Stablecoins in 2025: Developments and Financial Stability Implications, reported aggregate stablecoin market capitalization of $317 billion as of April 6, 2026, and described that level as more than 50% growth since early 2025. Do not present that historical figure as today’s total.
