If Tether is the street fighter of stablecoins, USDC is the one that showed up in a suit. Circle built its stablecoin for regulators, institutions, and auditors from day one, and in 2026 that bet is paying off in a big way. In this USDC review, we break down how the challenger works and why its growth now outpaces Tether’s. We also revisit the famous 2023 depeg weekend, where we caught one of our cleanest trades ever.
What Is USDC?
USDC is a dollar-pegged stablecoin issued by Circle, backed by cash and short-dated US Treasuries. As of August 2026, roughly $72 billion in USDC circulates across the market, making it the clear number two behind Tether.
The gap to the top is still wide, but the trend tells its own story. USDC grew around 73% year over year into early 2026, while Tether managed 36% over the same stretch. On raw transaction volume, the flip already happened. In June 2026, USDC carried about 67% of all adjusted stablecoin volume, moving roughly $1.2 trillion in a single month.
We hold USDC alongside our Tether stack, and the split is deliberate. USDT is our trading dollar; USDC is our regulated dollar. Different tools, different jobs.
History: Born in a Suit
Circle and Coinbase launched USDC in September 2018 through their joint Centre Consortium. From the start, the pitch was the opposite of Tether’s: full transparency, US-domiciled reserves, and regular third-party reporting. Centre wound down in August 2023, leaving Circle as the sole issuer.
The company itself went public on the NYSE in June 2025 under the ticker CRCL. A stablecoin issuer trading on the New York Stock Exchange, filing quarterly reports like any other public company, was unthinkable when we started in this market. Today it is the reality, and CRCL has been one of the stronger crypto equities of 2026.
Regulation keeps stacking in Circle’s favor. USDC operates comfortably under MiCA in Europe and sits cleanly within the GENIUS Act framework in the US. In July 2026, Circle also picked up a New York trust charter that opens the door to custody services. Everywhere regulators drew lines, Circle was already standing inside them.
Key Features
Transparent reserves. Cash and short-term Treasuries back every USDC, held primarily in an SEC-registered money market fund that BlackRock manages. Deloitte signs monthly attestations. No commercial paper mysteries, no Bitcoin on the balance sheet.
Native on 35 chains. USDC runs natively on Ethereum, Solana, Base, Arbitrum, Sui, and more than thirty other networks. Circle’s Cross-Chain Transfer Protocol burns and mints natively between chains, which beats trusting third-party bridges.
The DeFi standard. Deep USDC liquidity anchors lending markets, DEX pools, and yield strategies across every major ecosystem. Many protocols quote their TVL in USDC terms for a reason.
Institutional rails. Visa, Mastercard, Stripe, and BlackRock all run USDC integrations. When traditional finance touches stablecoins, it usually touches this one first.
Free minting and redemption. Institutional accounts at Circle Mint convert dollars to USDC and back at par with no fee, which keeps the peg arbitrage tight.
Fees
Circle charges nothing to mint or redeem at the institutional level, and holding USDC costs nothing. Your real costs are network fees and exchange spreads, same as any token.
Retail users buy USDC on exchanges, where spreads sit at fractions of a cent. Transfers cost whatever the chain charges: pennies on Solana and Base, more on Ethereum mainnet during busy hours.
One thing you give up is yield. Circle keeps the Treasury interest on reserves, which is the entire business model. If you want your stablecoins earning, you need lending markets or yield-bearing alternatives, which come with their own risks.
Security and Reserves
On paper, USDC is the safest large stablecoin in crypto. The reserves are boring by design: cash and short-dated Treasuries, disclosed monthly, attested by Deloitte, with the bulk sitting in a regulated BlackRock-managed fund. A public company with SEC reporting obligations stands behind it.
Boring is exactly what you want from a dollar. Yet USDC carries the same centralization trade-offs as Tether: Circle can freeze addresses and has done so for sanctioned wallets. Your USDC is a claim on Circle, not a bearer asset.
The usual scam warning applies here too. Fake USDC airdrops, spoofed contract addresses, and phishing sites imitating Circle are common. Only trust the official contract addresses listed by Circle, and treat any “USDC reward” landing unannounced in your wallet as poison.
And then there is the one weekend where the safest stablecoin broke.
The Depeg: When $1 Cost 88 Cents
March 2023. Silicon Valley Bank collapsed, and Circle disclosed that $3.3 billion of USDC reserves sat trapped inside it. Panic did the rest. Over that weekend, USDC lost its peg and traded down to roughly $0.88, an unthinkable number for a fully reserved stablecoin.
Everyone in crypto remembers where they were. We were at our desk, doing math. The exposure was about 8% of reserves, and even a total SVB loss meant USDC was worth far more than 88 cents. Markets were pricing in a wipeout that the numbers simply did not support.
So we took the trade. We scooped up depegged USDC with our other stablecoins, sat through a nervous Sunday, and swapped it all back once the peg restored. Regulators guaranteed SVB deposits, Circle confirmed full access to the funds, and USDC snapped back to $1 within days. One of the cleanest risk-reward setups we ever traded, courtesy of pure panic.
Two lessons survived that weekend. First, even the best-regulated stablecoin has banking risk, because dollars have to live somewhere. Second, depegs of solvent stablecoins are opportunities for anyone who reads the actual numbers instead of the timeline. Circle has since restructured its reserves to lean harder on Treasuries and reduce single-bank exposure.
Pros and Cons
Pros
- Most transparent reserves of any major stablecoin, with monthly Deloitte attestations
- Issued by a NYSE-listed public company with real disclosure obligations
- Compliant under MiCA and the GENIUS Act, so it works where regulators watch
- Native on 35 chains with official cross-chain transfers
- Deepest stablecoin in DeFi lending and liquidity pools
- Growing much faster than Tether in percentage terms
Cons
- Less liquid than USDT on offshore exchanges and emerging-market rails
- Circle keeps the reserve yield; holders earn nothing
- Centralized issuer with freeze powers
- The 2023 depeg proved banking risk is real
- Still less than half of Tether’s size
Who Should Use USDC
US and EU users should make USDC their default stablecoin. It is the one designed to survive regulatory scrutiny, and in Europe it fills the hole MiCA punched in Tether’s availability.
DeFi farmers basically have no choice. USDC anchors the deepest lending and LP opportunities across Ethereum, Base, Solana, and beyond, and plenty of airdrop campaigns count USDC deposits toward eligibility.
Businesses and anyone invoicing internationally will find USDC the easiest stablecoin to explain to a bank or an accountant. The public-company issuer and clean reserves shorten a lot of compliance conversations.
Traders on offshore exchanges will still find USDT pairs deeper. We keep both, and we suggest most serious market participants do the same rather than picking a side in the stablecoin war.

Final Words
USDC is what stablecoins look like when they grow up. Transparent reserves, a public issuer, regulatory approval on both sides of the Atlantic, and volume numbers that now dwarf its size on paper. The depeg weekend was its trial by fire, and coming back from 88 cents in days arguably proved the model rather than breaking it.
Tether still rules raw liquidity, and our trading stack reflects that. But the regulated world is being built on USDC rails, and betting against that trend gets harder every quarter. Read this alongside our Tether review to see both sides of the stablecoin war, then hold accordingly.
FAQ
Is USDC safer than USDT?
On transparency, yes: monthly Deloitte attestations, Treasury-heavy reserves, and a public issuer beat Tether’s disclosure. Both remain centralized IOUs, and the 2023 depeg showed USDC carries banking risk of its own.
What caused the USDC depeg in 2023?
Circle held $3.3 billion of reserves at Silicon Valley Bank when it collapsed in March 2023. USDC traded down to roughly $0.88 before regulators guaranteed deposits, and the peg fully recovered within days.
Does USDC pay interest?
No. Circle earns the yield on the Treasury reserves and keeps it. Holders who want returns need lending protocols or yield-bearing alternatives, each with extra risk.
Which chains support USDC natively?
USDC runs natively on 35 networks as of mid-2026, including Ethereum, Solana, Base, Arbitrum, Avalanche, and Sui, with Circle’s transfer protocol moving it between them.
Can Circle freeze my USDC?
Yes. Circle can freeze addresses and has done so to comply with sanctions and law enforcement. Everyday users rarely encounter this, but it is a real property of the asset.
Is USDC available in Europe?
Yes. USDC complies with MiCA, so regulated European exchanges list it freely, which made it the main beneficiary of Tether’s EU delistings.
