How to analyze any stablecoin in 30 minutes

Three questions that filter everything else

Every step below serves three questions from chapter 1. If you cannot answer them after thirty minutes, the rest of your notes do not matter.

First, whose legal obligation is the token? The answer is a named company with a jurisdiction and an address. "The smart contract" is not an answer, because a contract does not owe anyone a dollar. Second, who has the right to redeem at par, which means handing the token back to the issuer for exactly one dollar? Usually it is a short list of verified clients, and everyone else can only sell on a market. Third, what happens if the arbitrage loop stops for 48 hours? That loop is the trade in which a client buys the token below one dollar and redeems it at the issuer, pushing the price back up. It stops when a partner bank fails on a Friday, a hedge venue freezes withdrawals, or a regulator halts minting.

These three questions also set the vocabulary for the rest. A fiat-backed token is defended by redemption at the issuer, a crypto-backed token by selling collateral, and a synthetic token such as USDe by a futures hedge. Asking "who is the futures counterparty" of USDC, or "where is the cash" of USDe, wastes minutes. Name the design first.

The seven steps

The steps run in a fixed order because early answers speed up later ones. Knowing who controls the collateral often tells you the regulator, and knowing how redemption works predicts how liquid the token will be.

Step 1, mechanism and issuer (3 minutes). Open the terms of use and find the legal entity that issues the token and owes redemption. Write down its name, country and licence. Then name the design: redemption, over-collateral or hedge.

Step 2, the reserve page (4 minutes). Open the issuer's transparency page. Note what the reserve holds (cash, Treasury bills, repo, a money-market fund, gold, crypto), who holds it (which banks and custodians), and the date of the numbers. Assets outside cash and short government debt deserve a line of their own, because they move in price.

Step 3, the attestation (4 minutes). An attestation is an accountant's opinion, on a stated date, that management's claim about the reserve is fairly stated. An audit is a different document: it examines a reserve and its controls over a whole period. Write down five things: who signed, under which standard, for which date, what management asserted, and what the accountant did not test, such as liens or the reserve on other days.

Step 4, contract powers (5 minutes). Look up the token contract on a block explorer and the issuer's documentation. Find who can mint, who can freeze an address (block it from sending), who can pause all transfers, and who can upgrade the code. A multisig is a wallet that needs several named signers to approve, and you want to know whether each power sits behind a multisig or behind a single wallet with one key. On each chain, check whether the token is native (issued there by the issuer) or bridged (a claim on a bridge that holds the original elsewhere). The under-the-hood chapter explains each function.

Step 5, redemption terms (5 minutes). Find who may redeem, the minimum amount, fees, cut-off times and how long the dollar wire takes. Then ask the 48-hour question: if the issuer's main bank closed on Friday, is there a second bank, and does the issuer say what happens?

Step 6, distribution and liquidity (4 minutes). Use DefiLlama or RWA.xyz to see supply by chain, and check which exchanges and DeFi protocols carry the token. A token that lives mostly on one venue is only as liquid as that venue. The practical test is whether 50 mn USD could leave in a day without moving the price more than a few basis points.

Step 7, regulation (3 minutes). Check the claimed status in the regulator's own public register: the ESMA list of e-money token issuers under MiCA, the NYDFS or OCC charter lists in the US, the Bermuda or Hong Kong registers. A licence you cannot find in a register counts as no licence.

That leaves two minutes for the decision rule in the next section.

The five-minute version and the decision rule

With only five minutes, answer four things: the mechanism, who controls the collateral, how redemption works, and what the risks are. Every disaster in this course had a visible weakness in one of those four. Terra's UST had no independent collateral at all; its backing was its sister token. The tokens that broke in November 2025, xUSD, deUSD and USDX, rested on borrowed collateral placed in strategies nobody outside could verify.

For the full version, keep a scorecard with one line per step: a one-sentence answer, the source and its date, your confidence, and a red-flag box. Confidence is your own mark on the answer: high if it comes from a primary document you dated, medium if it comes from a dashboard or the issuer's marketing page, low if it rests on a secondary site or an inference. A red flag is a finding that, alone or with others, stops a business decision until someone does full due diligence.

The decision rule is mechanical. Four or more red flags, or low confidence on the mechanism, collateral control, redemption or risk steps, means full due diligence before any integration, listing or recommendation. The scorecard does not make the decision. It makes sure the gaps have names.

Gaps that are normal, and gaps that disqualify

Some missing facts are ordinary. A private issuer rarely publishes its operating costs. Few issuers disclose how many signers stand behind every admin key. DefiLlama, RWA.xyz and the issuer's own page often differ by a few percent because they count different things on different dates. A shallow depeg that recovered quickly may have no precise recovery time in the press. Write these down and move on.

Other gaps are findings in their own right, and each is a red flag:

• no attestation or audit of the reserve at all
• no named legal entity responsible for redemption
• no risk disclosure anywhere in the official documents
• a past depeg with no published explanation
• a claimed licence that no public register confirms

The difference is simple. A missing detail, such as an exact number or date, is a gap to note. A missing structure, meaning who is liable, where the money is, or whether redemption exists, is the result of the teardown.

Deep dive What the research papers cover, and what they miss

Academic work helps less than you might expect. The author's count in the OpenAlex research index, read on 5 September 2026, found 1,710 papers with "stablecoin" in the title or abstract since 2023. Most study what is easy to measure from prices: correlations, named crises, regulation. Only six had redemption mechanics as their subject, all from 2025 or 2026 and none yet cited, and none had admin keys, multisigs or custody risk in the title.

That tells you what data is public, not what practitioners ignore. Daily redemptions by channel and signer lists are not published, so nobody can run a regression on them. The answers for steps 4 and 5 sit in contracts and issuer documents, which is where the teardown sends you.

A worked teardown: USDC

USDC makes a good first case because its contract is public, its issuer is a listed company, and its worst weekend is well documented. The facts below were checked in September 2026.

Step 1. The issuer is Circle, listed on the New York Stock Exchange since June 2025. The design is fiat-backed: verified clients mint and redeem through Circle Mint, the company's primary desk, and the arbitrage loop holds the peg.

Step 2. Circle's reserve, per its Deloitte attestation of 6 November 2025, was about 13% cash at banks and about 87% the Circle Reserve Fund, a money-market fund holding short Treasuries and repo. There is no gold and no crypto. Bank concentration is the historical weak point: in March 2023 about 3.3 bn USD of reserves sat at Silicon Valley Bank when it failed.

Step 3. Deloitte signs a monthly attestation. Circle files audited company accounts as a listed firm, but a company audit is a different document from a full audit of the USDC reserve, which is not published. Supply figures also differ by method: the attestation counted 77.17 bn USD of USDC on 30 April 2026, while DefiLlama's on-chain count on 29 June 2026 was 73.71 bn USD. Different dates and different cuts make that a method gap, not a missing reserve.

Step 4. The USDC contract splits its powers into separate roles: one sets minting limits, others mint, pause, freeze addresses or rescue stray tokens. Circle can freeze an address but, unlike Tether, cannot destroy the frozen balance. The contract sits behind an upgradeable proxy, and the number of signers behind that admin key is not public, which earns a medium confidence mark. On each chain, check that you hold native USDC and not an older bridged version such as USDC.e.

Step 5. Only Circle Mint clients redeem at par with the issuer; anyone else sells on a market. The desk minimum is not public in the sources used here, another medium mark. The 48-hour question has a documented answer. Over the SVB weekend of 10 to 13 March 2023 the desk was closed for about sixty hours, USDC traded down to about 0.87 USD on 11 March, and it returned to one dollar within hours of the Monday announcement that deposits were safe. Circle later moved its banking to BNY Mellon.

Step 6. USDC lives on many chains, with native issuance on Ethereum, Solana, Base and others. Coinbase said more than a quarter of all USDC sat in its products in early 2026, and the derivatives exchange Hyperliquid held most of its roughly 7 bn USD of margin in USDC. That is deep liquidity with one large partner, which belongs in the risk line.

Step 7. Circle issues USDC as an e-money token under MiCA through its French e-money licence, holds a New York BitLicense, and received conditional OCC approval for a national trust bank in December 2025, followed by final approval on 10 July 2026. Each status can be confirmed in a public register.

Result: no red flags and no low-confidence answers on the four key steps, so the decision rule does not call for full due diligence. The one-sentence synthesis: USDC's main risks are its banks and its dependence on Coinbase, and its March 2023 depeg showed that a full reserve does not hold the price while the redemption desk is closed.

What to watch next

• GENIUS Act final rules, due to apply from 18 January 2027: they will set US standards for redemption timing and reserve disclosure, which makes step 5 easier to answer for US issuers.
• Monthly attestations moving toward audits: a published full reserve audit by a large issuer would raise the bar for step 3 across the market.
• Admin-key disclosure: an issuer that publishes its signer list and threshold turns a normal gap in step 4 into a checkable fact.
• Register coverage: as the UK, Hong Kong and Singapore licence stablecoin issuers, step 7 will have more registers to check and fewer claims you cannot verify.
