Issue 01 Inaugural · 2026 English edition

Most stablecoin coverage stops at the marketing page.

We picked the coins apart instead. The redemption mechanics behind USDT, USDC, DAI and FDUSD. What we actually paid to bridge between Ethereum, Tron, Solana and BNB Chain. How the BDO and Deloitte attestation letters differ from a real audit. What MiCA changed for European holders in 2026. Read it, decide for yourself.

From the editor

Most English stablecoin coverage is written by people who either work for an issuer or trade tokens for a living. We wanted a third option: read the attestations cover to cover, pay real bridge fees, read the SEC and ESMA filings, then write what we found. If we are wrong about a number, it goes on the corrections page with the date and what it should say.

FDUSD shrank after Binance rebalanced its trading pairs. PYUSD has grown by roughly 3.5x in eighteen months on PayPal's distribution.

Industry timeline

Ten events that changed the stablecoin map, 2021–2026

Each entry links to the longer piece where we walk through the document trail.

  1. 2021 · 02

    NYAG settles with Bitfinex and Tether

    New York Attorney General Letitia James announces an 18.5 million dollar settlement, banning Tether from trading with New York residents. The order forced the first detailed reserve breakdown the public ever saw from Tether.

  2. 2022 · 05

    Terra UST and Luna death spiral

    UST fell from 1 dollar to roughly 0.10 in four days. Luna went from 80 dollars to four-thousandths of a cent. About 60 billion of paper value evaporated. The episode rewrote how regulators see algorithmic designs.

  3. 2023 · 02

    NYDFS halts new BUSD issuance

    The New York Department of Financial Services orders Paxos to stop minting BUSD. The token started a slow eighteen-month wind-down from a 23 billion supply.

  4. 2023 · 03

    USDC SVB depeg, forty-eight hours

    Circle had 3.3 billion in reserves at Silicon Valley Bank when it failed. USDC fell to 0.8774 on Coinbase. The peg returned on Monday after the Treasury, Fed and FDIC announced backstops. Read the hour-by-hour version in the cornerstone report.

  5. 2023 · 08

    PYUSD launches

    PayPal launches a Paxos-issued dollar token. First mainstream stablecoin pushed by a consumer-payments brand rather than a crypto-native firm.

  6. 2024 · 06

    MiCA fully in force in the EU

    USDT's compliance posture in the EU comes under scrutiny. Several EU-licensed exchanges drop USDT spot pairs. EURC (Circle's euro token) picks up the gap.

  7. 2024 · 06

    Circle IPO on the NYSE

    Circle lists publicly under CRCL. Investors now read its quarterly statements with the same scrutiny as any listed bank.

  8. 2024 · 09

    TUSD repeated depegs

    TUSD slipped to about 0.97 multiple times. Disclosure gaps around the Techteryx takeover never closed. Supply fell from roughly 3 billion to under 500 million.

  9. 2025 · 03

    Hong Kong stablecoin ordinance

    The HKMA's licensing regime for fiat-referenced stablecoins becomes law. FDUSD positions for a first-wave licence.

  10. 2026 · 02

    USDT restricted on major EU venues

    End of the MiCA transition window. Most top EU exchanges fully delist USDT spot pairs. USDT euro-side liquidity migrates to OTC desks.

Why StableDesk

What we do that most stablecoin sites do not

01

We pay our own bridge fees

Every cross-chain number on the site comes from a transaction we sent ourselves. Hash, timestamp and gas figure are on file. We do not republish exchange marketing tables.

02

Corrections are public, dated, and kept

If we get a number wrong, the corrections page shows the old line, the new line, the date and the reason. We do not silently rewrite old posts.

03

We disclose the Binance relationship every page

The site earns a referral fee from Binance through code BN16188. Every page says so at the top, the foot of the article, and on the disclaimer. We still publish the parts of Binance that look bad.
