What is USDC
USDC is a US dollar-pegged stablecoin issued by Circle Internet Financial. Each token is backed one-to-one by cash and short-dated US Treasury bills held with regulated US custodians. Circle publishes monthly attestations from a major audit firm and reports holdings in detail. USDC is widely regarded as the most conservative major stablecoin from a reserve and disclosure perspective.
USDC runs natively on Ethereum, Solana, Polygon, Arbitrum, Base, Avalanche, and a growing list of Layer 2 networks. In iGaming, USDC pairs with USDT as the standard stablecoin offering across crypto-native operators. Regulated operators that accept stablecoins often accept USDC first because of the cleaner compliance profile.
How USDC moves through operator rails
Customers deposit USDC to operator-provisioned addresses on the chain of their choice. Solana and Polygon are popular for low-fee deposits; Ethereum is used for larger balances; Layer 2 networks (Arbitrum, Base) are gaining share. Confirmations clear in seconds to minutes depending on the chain.
Internally, operators credit USDC at one-to-one fiat equivalence and book wager and bonus activity in USD-denominated terms. Withdrawal signing follows the standard hot-wallet pattern, with cold-storage segregation for reserves not actively rotated through customer withdrawals.
Why USDC matters in B2B
For regulated operators, USDC is often the first stablecoin compliance and treasury teams approve, because reserves and disclosure meet the documentation requirements expected by MGA, Spelinspektionen, and similar regulators. For PSPs, USDC corridors carry lower regulatory friction than USDT in licensed jurisdictions. For compliance, USDC blacklist functions (Circle can freeze addresses on regulator request) are well-documented and predictable.

Both peg one-to-one to the US dollar. USDC is issued by Circle, audited monthly, and reserves are held in regulated US custodians. USDT is issued by Tether Limited with quarterly attestations.

Yes. USDC briefly traded below one dollar in March 2023 when Circle disclosed exposure to Silicon Valley Bank during the bank’s failure. The peg recovered within days after federal regulators guaranteed the deposits. The event is the only material peg deviation in USDC’s history.
Ethereum and Solana cover the majority of customer demand. Polygon and Arbitrum are strong additions for low-fee deposits. Base is the fastest-growing chain in 2025 and 2026, and operators targeting US-friendly crypto users are increasingly adding it.
No. On-chain USDC transfers are final once confirmed. Circle can freeze specific addresses on regulator request, which prevents the holder from transacting further, but cannot reverse a settled transaction.
