Current obstacles
- Bank-run riskIn March 2023 USDC briefly lost its $1 peg when $3.3B of reserves were stuck at failed Silicon Valley Bank.
Physics limits
- Redemptions can outrun liquidityA $1 promise needs cash on demand. In a run, redemptions can outpace how fast even Treasuries turn into cash, and bank deposits above insurance limits can freeze, as in March 2023.
- Blockchains can't see bank accountsWhether the reserves exist is an off-chain fact. No smart contract can check a bank balance, so holders must rely on auditors, attestations and regulators.
- Crossing chains needs a trusted signerA chain can't cheaply verify another chain's history. Moving USDC relies on Circle's signed attestation, or on light-client proofs that are costly to run on-chain.
How it works

Dollars in, tokens out
Approved businesses send dollars to Circle, which creates the same number of USDC on a blockchain. Redeeming burns the tokens and returns dollars.
Cash and short Treasuries
Most reserves sit in a BlackRock-managed money market fund of short US Treasuries and repos, plus bank cash, with monthly independent checks.
CCTP burns and re-mints
To move USDC between chains, CCTP burns it on the source chain and Circle signs a message letting the destination chain mint the same amount.
Freezable by design
The token contract lets Circle freeze addresses on legal orders, which regulators require but which is a point of central control.
