$USDC USDC, the world’s second-largest stablecoin, hit a $37B market cap, up 10% in 2025, backed 1:1 by USD and treasuries. Issued by Circle, it’s a go-to for DeFi, remittances, and now Stripe’s Stablecoin Accounts in 101 countries. Daily transfers average $7B, with 3M wallets active. Ethereum hosts most USDC, but Solana and Polygon are gaining. Transparency reports confirm full reserves, easing trust concerns post-2023 banking scares. Partnerships like Visa and Coinbase fuel adoption, though regulatory scrutiny looms. USDC’s peg held steady at $1.00, unlike Tether’s wobbles. Is USDC the future of digital dollars, or a regulatory target?
