# How to analyze any stablecoin in 30 minutes

A new dollar token is not understood by reading the supply ticker. It is understood by answering sixteen questions on a clock, or four of those questions in five minutes, and by knowing which holes in public information are ordinary and which ones stop the work. Academic papers help on prices and named crises. They barely touch redemption, and they do not touch admin keys.

## What you'll learn

- Filter any token with three questions: whose obligation it is, who may redeem at par, and what happens if the arbitrage loop stops for 48 hours.
- Run a sixteen-question teardown in thirty minutes, and a four-question version in five.
- Fill a scorecard with a one-sentence answer, a source and date, a confidence mark, and a red-flag box, then apply the decision rule.
- Tell a normal gap from a disqualifying one, and read an attestation without treating it as an audit.
- Use OpenAlex volume as a map of what is easy to measure, not as a measure of what is known about risk.

## Three questions that filter the rest

[Chapter 1](/en/blog/stablecoins/what-one-usdc-means/) split "1 USDC = 1 USD" into a technological claim, a legal claim and an economic claim, then left three questions about the loop: who can pass, what it costs, and when it is open. This chapter keeps those, and restates them as a filter for whether the other thirteen questions are worth the remaining minutes.

Whose legal obligation is the token. The answer is a named legal entity with a jurisdiction and an address, not a brand. Possession of USDC does not, by itself, create a right to walk up to Circle and be paid. Circle Mint is the desk. Tether Limited runs the same structure for USDT. If the name cannot be written down, the later questions about reserves are questions about an unnamed book.

Who has the right to redeem at par. Direct redemption is a primary-market trade for a verified client. A holder who bought on an exchange has a secondary-market exit at the screen price. Mixing those two is the most common error in a pitch deck. USDG is described in [chapter 3](/en/blog/stablecoins/types-and-pegs/) as fully redeemable 1:1, a stronger retail term than USDT's and USDC's institutional desks. USDe has no formal par window.

What happens when the arbitrage loop stops for 48 hours. A partner bank fails on a Friday, a hedge venue suspends withdrawals, a regulator pauses mint. Either a backup path exists, or the price drifts without a bound. Circle's loop was closed operationally for about sixty hours in March 2023. The reserve still existed. The print went to about 0.87 USD on 11 March because the desk was shut.

Those three answers set the vocabulary for questions 2 through 6. Question 4, who controls the collateral, often fills question 13, regulation, without a second document: an OCC trust charter, a NYDFS BitLicense, or a blank. Question 6, redemption, predicts question 14, liquidity, because the arbitrage-threshold arithmetic only runs while someone can actually pass through the desk.

## Sixteen questions in thirty minutes

The sixteen questions have a fixed thirty-minute budget. Four of them, collateral type, mint mechanics, customer identity, and the cycle-survival synthesis, take sixty seconds each. Two of them, risks and regulation, take nearly five minutes each because they rarely fit in one document. The other ten share what is left. The split is the author's allocation of that outline, not a stopwatch reading. If the offering document is missing, the clock overruns, and that overrun is itself a result.

Order is not decorative. Question 1 names the mechanism family, so questions 2 to 6 are asked in that family's language: a cash desk, a vault, or a hedge book. Asking "is it fully reserved" of USDe is a category error. Asking "who is the futures counterparty" of USDC is the same error in reverse. USDe is a synthetic, not a payment stablecoin.

1. Peg mechanism. Redemption arbitrage, over-collateralization with liquidation, or a delta-neutral hedge. "Fully backed" is not a mechanism. USDC at 0.87 USD in March 2023 was fully reserved on the technological and legal layers while the loop was closed.
2. Collateral type. Cash and T-bills, over-posted crypto, a hedged book, metal, or nothing. Sixty seconds. If the type cannot be named, stop.
3. Mint mechanics. Who may create tokens, against what, and whether that permission is a contract role or a desk. Sixty seconds.
4. Who controls the collateral. A licensed entity with an address, a DAO, or a book of futures at venues. This is the question that often answers regulation for free.
5. The attestation or reserve page. Named attestor, snapshot date, standard, and what the letter does not cover. How to read that page sits one section down.
6. How redemption works. Who may demand one dollar for one token at the issuer, on what ticket, on which days. Not "I can always sell for a dollar."
7. Who the customer is. Primary-market client, secondary holder, or a user who showed up for a reward. Sixty seconds. PYUSD's supply tracked the reward, not transactional use.
8. Freeze and blacklist. USDT and USDC ship a blacklist. USDS added a freeze DAI never had.
9. Yield and wrappers. The GENIUS Act bars a payment-stablecoin issuer from paying interest directly. Wrappers remain an open regulatory question as of September 2026.
10. Risks. Nearly five minutes. If official documentation has no risk section, that is a red flag on its own.
11. Depeg history. Depth does not predict return. USDC fell 13% and came back. USDX fell more than 40% and did not. [Chapter 2](/en/blog/stablecoins/history/) keeps the episode table. A depeg with no post-mortem is disqualifying.
12. Distribution. DefiLlama and RWA.xyz against the token's own documentation, dated. A few percent of aggregator disagreement is normal.
13. Regulation. Nearly five minutes. A licensed-status claim absent from every public register is disqualifying. Question 4 often pre-fills this cell.
14. Liquidity. Whether 50 mn USD can exit without moving the price more than a few basis points. Question 6 predicts the answer.
15. Named legal entity. No named party responsible for redemption is a red flag on its own.
16. Cycle-survival synthesis. Sixty seconds. Fold questions 1, 4, 6 and 10 into one sentence: what breaks first, and who is on the other side of it.

![Sixteen questions against a time budget and a red-flag rule. Four or more red flags, or low confidence on questions 1, 4, 6 or 10, means full due diligence before any business decision. Time budgets are the author's split of the outline, not a measured figure.](https://szyma.co/blog/img/teardown-scorecard.1596a848.svg)

The parallel habit for a tokenized fund, with a different asset class and a thirteen-question card, is [How to analyze any RWA in 30 minutes](/en/blog/rwa/thirty-minute-teardown/).

## Four questions in five minutes

The five-minute version answers only questions 1, 4, 6 and 10: peg mechanism, who controls collateral, how redemption works, risks. Every historical disaster named in this series, UST, deUSD, xUSD, USDX, FDUSD, had a visible weakness in exactly one of those four points. The Polish closing chapter lists FDUSD in that set; the specific print is not restated in the sources used for this chapter, so the name is kept and the depth is not invented. Distribution and regulation matter. They are rarely what killed the token by themselves.

The Polish closing chapter asked the same four, with the 48-hour loop stop sitting inside the risks cell.

> **Example:** Run the five-minute version on UST as it stood in early May 2022. Peg mechanism: mint and burn of LUNA, no independent collateral. Who controls collateral: there is none to control. Redemption: a sister-token trade, not a cash desk. Risks: a death spiral if LUNA demand has a ceiling. The token fails before a white paper, a listing, or a TVL chart is opened. deUSD, xUSD and USDX in November 2025 fail the same four at collateral control and redemption: yield sat on borrowed-collateral strategies without a verifiable, liquid hedge at a named counterparty.

The five-minute pass produces four sentences and a list of holes, not a safe/unsafe stamp. The thirty-minute pass fills the other twelve so that a hole is named rather than skipped.

## The scorecard and its decision rule

Each of the sixteen questions has five columns: the question, a one-sentence answer, a source with a date, a confidence mark, and a red-flag box.

**A red flag** is a gap or a fact that, on its own or in a stack, means the product cannot be used in a business decision until someone has done full due diligence. It is not a moral label. It is a stop.

**Confidence** is the reader's mark on how sure that one-sentence answer is, given the source level. High means a primary document dated by the reader. Medium means a dashboard or an issuer page. Low means a secondary portal, a missing document, or an inference. Low confidence on questions 1, 4, 6 or 10 is treated as a red flag even when the red-flag box is empty, because those four are the five-minute filter.

The decision rule is mechanical. Four or more red flags, or low confidence on any of questions 1, 4, 6 or 10, triggers full due diligence before any business decision.

BDO, Deloitte and KPMG are the attestor names that themselves carry a signal. Circle's USDC page is a monthly Deloitte attestation plus weekly disclosures. Tether's USDT page is quarterly BDO Italia, under ISAE 3000, which is an assurance opinion on management's assertion for a stated date, not a year-round test of controls. Paxos moved PYUSD's attestor to KPMG. Naming the firm is part of question 5. It is not a substitute for reading what the letter covers.

## Gaps that are normal, and gaps that disqualify

Some missing numbers are ordinary. A private issuer's exact operating-cost breakdown is not public, and Tether does not file a 10-K. An undisclosed multisig signer count, beyond a headline number of signers, is common. A few percent of disagreement between DefiLlama, RWA.xyz and the token's own page is a method gap, not evidence that the reserve is short. Circle's attestation showed 77.17 bn USD of USDC on 30 April 2026, net of unissued and denied tokens; DefiLlama's raw on-chain figure was 73.71 bn USD on 29 June 2026. Different dates, different cuts. They are not averaged. A shallow depeg with no precise recovery timestamp in the press is annoying and not, by itself, disqualifying.

Disqualifying gaps are red flags on their own:

- the issuer publishes no attestation or audit at all
- no named legal entity is responsible for redemption
- official documentation contains no risk disclosure
- a depeg exists with no published post-mortem
- a claimed regulatory status cannot be verified in any public register

**An attestation**, recalled from [chapter 3](/en/blog/stablecoins/types-and-pegs/), is an accountant's opinion on management's assertion for a stated date. It does not confirm reserve composition in every line, encumbrances, or internal controls. **An audit**, in the reserve-specific sense that chapter uses, is a full examination of the reserve over a period. As of 2026, neither USDT nor USDC has a published full reserve-specific annual audit in these sources. Circle's financial statements as a public company are a different object from a reserve audit of USDC. A proof of reserves is a third document: a moment-in-time check that some assets exist. It does not, by itself, say they are unencumbered or that they cover the whole liability.

Reading an attestation, in practice, is five lines on the scorecard. Who signed it (BDO, Deloitte, KPMG, or nobody). Which standard (ISAE 3000, an AICPA attestation standard, or an unnamed letter). Which date the snapshot covers, written in the same cell, because a quarterly letter does not speak for the weeks after it. What management asserted (usually that circulating tokens are covered by the fair value of reserves). What the accountant did not test (composition, liens, the weekend the bank is closed, the desk hours). If any of those five lines is blank, confidence on question 5 is low. If the first line is blank, question 5 is a red flag.

A working source hierarchy for this asset class, from closest to a binding statement to furthest:

1. Redemption terms and the attestation. They bind the issuer, or they are the accountant's opinion on what the issuer asserted.
2. A regulator register or filing. GENIUS, MiCA EMT, NYDFS, OCC charter. Question 13 lives here.
3. The issuer's own transparency page. True and selective.
4. A dashboard. DefiLlama, RWA.xyz. Dated, filters usually hidden.
5. A secondary portal or an academic preprint that repeats a dashboard. A lead, not a number to act on.

Most circulating supply figures sit on levels four and five. They need a fresh read and the reader's own date. If that read cannot be done, the number is citable with a caveat, which is a medium or low confidence mark, not a silent copy.

> **Watch out:** Zero papers on admin keys, in the next section, is not evidence that practitioners skip custody risk. It is evidence that academia does not have a public series to regress. The teardown still asks who holds the keys, using the contract and the docs, because that is where the answer sits. The RWA series works the same question on fund tokens in [Who holds the keys](/en/blog/rwa/who-holds-the-keys/).

## What the papers cover, and what they miss

OpenAlex is a research index. The counts below are OpenAlex's API read on 5 September 2026: 1,710 records from 2023 through that day with "stablecoin" in the title or abstract. Annual counts went 213, then 190, then 440, then 867. 2026 is 8 months and 5 days, not a full year. A full-year 2026 total is not stated here.

![Stablecoin research volume by channel from the Polish research.md table, 2023 to 5 Sep 2026. No OpenAlex CSV is in this repo. Raw 2026 count is 867, of which 238 are zero-citation dataset deposits. Strip those and 2026 is 629, growth of +43.0% over 2025 rather than +97.0%.](https://szyma.co/blog/img/research-by-channel.58b7fcd0.svg)

Raw 2026 growth reads as +97.0% over 2025. 238 of the 867 records are automated data deposits, mostly one Zenodo hourly-dataset series, all zero-citation. Excluding them, 2026 falls to 629 papers and growth drops to +43.0%. The preprint and repository share of the raw 2026 pile is 553 of 867. Peer-reviewed journals are 171 of those 867, down from 206 in the whole of 2025, which is expected: review takes months, and 2026 is incomplete. Central-bank and major-institution authorship (BIS, ECB, Fed, NBER, IMF) is 67 of 1,710 papers, 3.9%, growing 9, then 8, then 22, then 28 by year, with the market rather than with the automated deposits.

**A peer-reviewed paper** is a text that has passed an editor and referees at a journal with an ISSN. **A preprint** is a working paper posted to a repository, SSRN, arXiv, Zenodo, before or instead of that process. Of the 40 most-cited papers in the 1,710, 33 (82.5%) are peer-reviewed, though peer-reviewed journals are only 33.0% of the whole corpus (565 of 1,710). Average citations are 4.18 for a peer-reviewed paper against 0.41 for a preprint or repository entry, counting the whole set, which favours older papers that have had time to be cited.

The literature skews toward what is easy to measure from a price series: correlations, named events, regulation. DeFi has 243 of 1,710 titles (14.2%). Regulation, law and compliance has 242 (14.2%). Redemption mechanics have 6 papers, all 2025–2026, zero citations each. Admin-key, multisig and custody-risk words in the title: zero papers out of 1,710. That is not a finding that nobody studies those risks. It is a finding that the data a regressor would need, daily redemptions by channel, signer lists beyond a count, listing-promotion contracts, are not public.

Terra/UST has 27 papers with those names in the title. SVB/USDC has 7. The highest-cited paper in the set is *Silicon Valley Bank bankruptcy and Stablecoins stability* (International Review of Financial Analysis, 2023, 61 citations). The mechanics that decided whether those pegs returned, the open or closed loop, are the six uncited papers.

A practical cut for whether a record is worth opening: an author with a university or central-bank affiliation, a title that states a research question rather than a figure filename, and either a citation or a named publisher (SSRN under a university, NBER, IMF, a journal with an ISSN). Absence of peer review does not disqualify. SSRN and arXiv are ordinary early channels in economics. Absence of any method to check does.

> **My take:** The skill is not collecting sixteen answers. It is refusing to treat a blank as a pass. A thirty-minute teardown that ends with four red flags is a completed teardown. Waiting for the next jump in OpenAlex counts will not fill questions 6 or 4. Those answers, if they exist, are in the issuer's documents, in a BIS paper that may not even carry a DOI, or they are not public.

## Key takeaways

1. Three filter questions, whose obligation, who may redeem at par, what happens if the loop stops for 48 hours, decide whether the other thirteen are worth asking; they are the chapter 1 loop questions restated as a gate.
2. Sixteen questions share a thirty-minute budget: four take sixty seconds, risks and regulation take nearly five minutes each, and the rest share what is left.
3. The five-minute version is questions 1, 4, 6 and 10. UST, deUSD, xUSD, USDX and FDUSD each had a visible weakness in one of those four.
4. The scorecard has five columns per question. Four or more red flags, or low confidence on any of 1, 4, 6 or 10, means full due diligence before a business decision.
5. Normal gaps: private opex, undisclosed signer lists beyond a count, a few percent of aggregator disagreement, no precise recovery clock after a shallow depeg.
6. Disqualifying gaps: no attestation or audit, no named redemption entity, no risk disclosure, a depeg with no post-mortem, a regulatory claim absent from every public register.
7. OpenAlex indexed 1,710 stablecoin papers from 2023 to 5 September 2026; annual counts 213, 190, 440, 867, with 2026 incomplete. Strip 238 zero-citation dataset deposits and 2026 is 629, +43.0% not +97.0%.
8. Redemption has 6 papers, all uncited, all 2025–2026. Admin key, multisig and custody risk have zero title hits in 1,710. That is a data-availability result, not a practitioner result.

## Glossary

- **Red flag**: a gap or fact that, alone or stacked to four, stops a business decision until full due diligence is done.
- **Confidence**: high if the answer sits in a primary document the reader dated; medium on a dashboard or issuer page; low on a portal, a missing file, or an inference.
- **Attestation**: an accountant's opinion on management's assertion for a stated date. Recalled from [chapter 3](/en/blog/stablecoins/types-and-pegs/).
- **Audit** (reserve-specific): a period examination of the reserve. Not published for USDT or USDC as of 2026 in this material.
- **Peer-reviewed**: passed referees at a journal. 565 of 1,710 records; 33 of the 40 most-cited.
- **Preprint**: a working paper on a repository before or instead of that process. SSRN and arXiv are ordinary; a Zenodo hourly dump with no method is not.
- **OpenAlex**: the open research index behind the 1,710-record count, read 5 September 2026.
- **Cycle-survival synthesis**: question 16, one sentence that names what breaks first from questions 1, 4, 6 and 10.

## Caveats

Time-per-question budgets are the author's split of a 30-minute outline, not a measured figure. The figure caption states that.

A full-year 2026 paper count is not given. The Polish edition's linear extrapolation of about 1,276 is an incomplete-year projection, not a model, and is omitted here.

The channel split in the figure is the table in `content/blog/stablecoins/research.md`. No OpenAlex CSV sits in this repo, so no further split (for example by `kanal` beyond that table) was drawn.

FDUSD is named in the Polish five-minute list. The depth of that print is not in the sources used for this chapter and is not invented.

Title-keyword topic counts are approximate. A paper that studies redemption under a generic "stability" title is not in the six. The true number of papers that touch redemption in the body may be higher.

The 67 central-bank and institution papers are tagged from OpenAlex affiliation and publisher fields. Historical affiliation is not the same as writing in an official capacity.

Zero title hits for admin key, multisig and custody risk is not a claim that practitioners ignore those risks.

Yield wrappers had no final US ruling as of September 2026. Question 9 records that as an open cell, not as a pass.

The five-column scorecard is a working tool. It is not a licence, a rating, or an investment recommendation.
