what's USDCx?
USDCx is a stablecoin issued by Circle through its xReserve infrastructure, maintaining a 1:1 backing with USDC reserves held in custody. It enables native USD liquidity on various blockchains without bridges or wrapping, supporting compliant, institutional-grade transactions. Designed for privacy-preserving payments and cross-chain access, USDCx has launched on networks like Aleo for banking-level privacy, Stacks for Bitcoin L2 DeFi and commerce, and Canton Network for enterprise workflows. Institutions can bridge USDC directly into these ecosystems, leveraging Circle's regulated reserves for seamless dollar movements on specialized chains.
