You Think Holding a Stablecoin Means Holding Dollars: The Trust Structures Behind USDT, USDC, and DAI

In the world of crypto, stablecoins feel like the one thing you do not need to worry about. The price barely moves. It tracks the dollar. Sitting in your wallet, it seems like nothing can go wrong. But that feeling is worth examining. What you hold is not a dollar. It is a promise to exchange for a dollar, issued by a specific institution. Understanding that distinction is where protecting yourself in Web3 begins.

Stablecoins are not dollars. They are a form of credit promise.

Take USDT as an example. Tether issues USDT and claims that every token is backed by an equivalent amount of dollar reserves. You deposit one dollar, receive one USDT, and in theory you can redeem it at any time. That mechanism keeps USDT's price close to one dollar. But USDT itself is not a dollar. It is more like a redemption promise issued by Tether: under the right conditions, you can exchange it back for something close to a dollar. The real value of that promise depends on whether Tether actually holds sufficient reserves and whether you can actually redeem it when you need to.

USDC and DAI operate differently, but the same logic applies. Every stablecoin is a promise, and different promises rest on different trust structures.

When you hold USDT, you are trusting several things. You are trusting that Tether holds sufficient reserves to back all USDT in circulation. In 2021, the CFTC found that Tether had reserve disclosure problems during a past sample period. Since then, Tether has improved its disclosures and moved toward more complete audit processes. It shifted to a quarterly attestation regime and in March 2026 formally engaged KPMG for its first full financial audit. But differences in transparency mechanisms between USDT and USDC remain. USDC publishes monthly Deloitte attestations and more detailed reserve disclosures. USDT uses a quarterly attestation regime. The two differ in attestation frequency, the scale of the attesting firm, and the granularity of what is disclosed. Choosing which stablecoin to hold is also a choice about which transparency structure you are willing to accept.

There is another dimension worth understanding. Stablecoins operate under a fundamentally different regulatory logic than decentralized tokens. If you assume they follow the same rules, that assumption is worth revisiting. Tether has the ability to freeze specific addresses at the request of regulators, and has done so in practice. If an address is flagged for any reason, its USDT can be frozen by Tether without any prior notice.

You are also trusting that secondary market liquidity holds under pressure. Most ordinary users do not redeem USDT directly with Tether. They sell it through exchanges. If that secondary market becomes thinner than expected under stress, a discount can emerge even before any fundamental problem exists.

What is different when you hold USDC

USDC is issued by Circle. As of now, its transparency is somewhat higher than USDT's. Deloitte publishes monthly attestations and reserve disclosures are made weekly. USDC is also more aligned with regulatory requirements. But what happened in March 2023 showed that trusting Circle is not the same as having no risk.

On March 10, 2023, Silicon Valley Bank announced its collapse due to a liquidity crisis. That evening, Circle disclosed something that rattled the market: $3.3 billion of USDC reserves were held at Silicon Valley Bank, and those funds were frozen. That $3.3 billion represented approximately 8 percent of USDC's total reserves of around $40 billion at the time.

After the news broke, USDC's price in secondary markets fell quickly below one dollar, reaching an overnight low of $0.8789. Anyone who needed to convert USDC to dollars or other assets at that moment would have lost more than 10 percent, even though USDC is theoretically always worth one dollar.

That weekend, the US Treasury, the Federal Reserve, and the FDIC jointly announced full protection for all Silicon Valley Bank depositors beyond the normal $250,000 limit. Circle's $3.3 billion was recovered in full, and USDC's price returned close to one dollar within days. The event had a good outcome. But it revealed a structural reality: USDC's stability that weekend was supported by a temporary government decision, not solely by Circle's reserve mechanism. A Federal Reserve research report published afterward noted that without government intervention, the shortfall in Circle's reserves could have exceeded its total shareholder equity at the time.

When you hold USDC, you are trusting Circle, the stability of the US regulatory framework, and the willingness of the government to intervene when pressure appears.

Looking at the transparency structures of USDC and USDT side by side, the difference in disclosure frequency is observable. USDC publishes monthly Deloitte attestations with weekly reserve composition disclosures. USDT publishes quarterly BDO Italia attestations. This is an objective difference in the official transparency regimes of the two issuers.

What you are trusting when you hold DAI

DAI is different from USDT and USDC. It has no centralized issuer and no company holding reserves on your behalf. DAI is generated through MakerDAO's smart contracts, which require users to deposit overcollateralized assets before DAI can be minted. If the value of the collateral falls below a certain threshold, the system automatically liquidates to ensure DAI remains sufficiently backed.

This design removes the need to trust any single company. But it introduces a different set of trust layers. You are trusting that MakerDAO's smart contract code contains no exploitable vulnerabilities. You are trusting that MakerDAO's governance mechanisms will make sound decisions over time. You are trusting that the market liquidity of the collateral assets will not collapse completely under extreme stress.

Decentralization does not eliminate trust assumptions. It relocates them.

A look back at historical stress tests: stability is a normal-conditions state

The history of all three stablecoins records the same pattern. Under normal conditions, they look nearly identical. When pressure appears, what they actually depend on starts to surface, and the conditional nature of their stability becomes visible.

In May 2022, the collapse of Terra and UST triggered severe volatility across the crypto market. USDT briefly fell to $0.9485 during the panic. DAI's collateral values dropped sharply and the system triggered large-scale automatic liquidations. The peg held, but the process revealed the real pressures that decentralized stablecoins face under extreme conditions. In March 2023, USDC fell to $0.8789 during the Silicon Valley Bank crisis and recovered over a single weekend only because of a temporary government decision.

What regulation is changing

In 2025, the United States passed the GENIUS Act, requiring stablecoin issuers to back each token one-to-one with high-quality liquid assets and submit to regular audits. Implementation rules take effect on July 18, 2026. Hong Kong passed its Stablecoin Ordinance in 2025, with eight licensed issuers currently operating.

These frameworks position compliance-oriented stablecoins like USDC more favorably. USDT faces comparatively greater regulatory pressure because its reserve transparency and audit standards have more distance from the new requirements. Regulatory tightening is a directional shift, not a conclusion. Rules will continue to evolve and requirements will continue to diverge across jurisdictions. The trust structure of the stablecoin you hold today may change substantially over the next few years as regulation develops.

What you are actually choosing

Most people who enter Web3 hold stablecoins at some point, and the feeling is that they are just sitting quietly in the wallet, stable, doing nothing. That feeling is not quite accurate. Choosing to hold USDT is choosing to trust Tether's reserve management and regulatory compliance. Choosing to hold USDC is choosing to trust Circle, the US regulatory framework, and the government's willingness to intervene under pressure. Choosing to hold DAI is choosing to trust MakerDAO's governance mechanisms and the ongoing integrity of its smart contracts.

These are not judgments about which is better. They are descriptions of what is already embedded in the choice when you buy a stablecoin. Stablecoins solve the volatility problem of crypto assets, but they replace market risk with a different set of variables: the creditworthiness of a specific institution, secondary market liquidity, a specific regulatory environment, and specific market conditions.

You cannot fully avoid these dependencies, just as you cannot put money in a bank without depending on that bank. But you can understand what those dependencies actually are before you make the choice. In Web3, no third party can recover losses on your behalf if something goes wrong with a stablecoin. Understanding what you are trusting, before the problem appears, matters more than any remedy that might come after.
