ChainCatcher Message, Stacks announces the official launch of USDCx. This is a stablecoin based on Circle’s new xReserve infrastructure, supported by USDC. The launch of USDCx establishes a native dollar channel with institutional-level liquidity for the Bitcoin Layer 2 ecosystem, enabling funds to settle directly on the Bitcoin network.
On the technical backend, USDCx is issued through Circle xReserve’s non-custodial smart contracts, providing cryptographic proof to ensure token transparency. Additionally, the asset utilizes Circle’s cross-chain transfer protocol (CCTP) to achieve “burn and mint” cross-chain transfers across more than 15 supported blockchains, thereby avoiding third-party bridge security risks and addressing liquidity fragmentation issues.
Currently, several leading protocols within the Stacks ecosystem have begun integrating USDCx. Zest Protocol has incorporated it into its institutional-grade Bitcoin lending pool, Granite supports users borrowing USDCx with BTC as collateral, and Bitflow has launched related deep liquidity pools and trading pairs. Furthermore, mainstream Stacks wallets such as Xverse and Leather have achieved first-day support. To optimize liquidity, the official encourages users who originally held aeUSDC (the old bridged USDC) to migrate to USDCx via the Stacks official bridge.
