Usdc

Circle's USD-redeemed stablecoin, audited and backed by short-duration Treasuries and same-day USD cash. Same-day primary-market redemption with US banks is the structural anchor for the peg.

Usdt

Tether's USD-pegged stablecoin, the dominant pair currency on most non-US crypto venues. Primary-market redemption is slower than USDC; secondary-market peg carries a premium during risk-on minutes.
