Tether (USDT)

Tether's USDT is the dollar most of crypto actually runs on. Launched in 2014, it is the largest stablecoin by a wide margin, the default quote currency on most exchanges, and — through its Treasury holdings — one of the larger buyers of US government debt anywhere. It is also crypto's longest-running controversy, which is exactly why it deserves coverage that neither cheerleads nor sneers. This hub collects MEXC Learn's Tether coverage. The coverage splits three ways. Reserves and the record. Tether publishes quarterly attestations showing reserves dominated by short-term US Treasuries, alongside holdings including bitcoin and gold. The criticisms are part of the record too: it has never published a full audit, and in 2021 it settled with US and New York regulators over how reserves had historically been described. So is the counter-record: through every major stress event, including the 2022 collapse that killed an algorithmic rival, USDT processed redemptions in size and the peg held after brief wobbles. Articles here cover both without blinking. Use. Why liquidity begat liquidity until USDT became the unit crypto prices itself in, how it moves across networks with very different fee profiles, and its outsized role in emerging-market dollar access. Structure and rules. Who Tether the company is, where its considerable profits come from, its freeze powers and law-enforcement cooperation, and how the 2025 US stablecoin law reshapes the ground it operates on.

Tether (USDT) FAQ

A dollar-pegged stablecoin issued by Tether, launched in 2014 and now the largest in existence — the default trading and settlement currency across most of crypto. Each USDT is intended to be redeemable for one dollar from the issuer, with reserves held predominantly in short-term US Treasuries. Its scale is the point: USDT is less an asset people invest in than the unit crypto denominates itself in.

Per Tether's quarterly attestations, the reserve is dominated by US Treasury bills, with the remainder spread across holdings that have included bitcoin, gold, and secured lending — a more varied mix than its main rival's. The attestations are point-in-time reports by an accounting firm, not a full audit, and the absence of one remains the standing criticism. The composition shifts quarter to quarter; read the latest report, not summaries of old ones.

Wobbled, never broken. The sharpest test came in 2022, when an algorithmic stablecoin's collapse sent USDT briefly to around $0.95 amid panic selling; Tether processed billions in redemptions within days and the peg recovered. Earlier episodes followed the same shape. The honest reading: the redemption machinery has worked every time it was tested — and every test was survived, not guaranteed.

The company has published attestations for years and has said audits are coming longer than critics can count. Explanations range from the complexity of auditing a novel global issuer to major firms' reluctance to take the engagement. Whatever the cause, the gap is real: an attestation confirms holdings at a moment; an audit tests controls over time. In 2021, Tether paid regulatory settlements over how reserves had historically been described — context any honest answer includes.

It is the platform's working currency. Most spot pairs quote in USDT, perpetual futures margin and settle in it, Earn products accept it, loans pay out in it, and RealStocks purchases fund with it — converting to dollars for the actual share settlement. For most users, USDT is the first thing acquired and the thing every other position is measured against. That centrality is why understanding it matters more than most assets you might actually be trading.
