Can I convert between USDT and USDC easily?

Yes, most major exchanges support both, and conversion is generally quick and low-cost.

Do both maintain a $1 peg equally well?

Both have generally held their peg closely, though both have experienced brief deviations during periods of market stress.

USDT vs. USDC: What's the Difference?

Not financial, legal, or tax advice. Not a recommendation to hold either asset. Stablecoins carry issuer and reserve risk.

USDT (Tether) and USDC (Circle) are the two largest fiat-backed stablecoins, both aiming to hold a steady $1 value, but they differ in who issues them, how transparent their reserves are, and where they're most commonly used. Both fall under the broader category covered in \[pillar hyperlink: What Are Stablecoins\].

Issuers

USDT is issued by Tether, a company with a long history in the space and by far the largest stablecoin by circulating supply. USDC is issued by Circle, a US-based company that has generally emphasized regulatory compliance and banking partnerships.

Backing

Both claim to be backed roughly 1:1 by cash and cash-equivalent reserves, primarily short-term US Treasuries and similar instruments. See Types of Stablecoins for how this fiat-backed model compares to crypto-backed and algorithmic designs.

Transparency

USDC has generally published more frequent and more detailed reserve attestations. Tether has increased its disclosures over time but has historically faced more scrutiny and skepticism over reserve composition than USDC.

Use cases

USDT sees very heavy use on exchanges and in trading pairs globally. USDC is widely used in DeFi applications and by institutions that prioritize its compliance posture. In practice, both function similarly for everyday holding and transfers.
