ChainCatcher reports that Stacks has officially launched USDCx . This is a stablecoin backed by USDC, built on Circle's new xReserve infrastructure. The launch of USDCx establishes a native, institutional-grade liquidity-rich USD channel for the Bitcoin Layer 2 ecosystem, enabling funds to be settled directly on the Bitcoin network.
At the underlying technology level, USDCx is issued through a non-custodial smart contract on Circle xReserve, providing cryptographic proofs to ensure token transparency. Simultaneously, 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 mitigating the security risks of third-party bridges and resolving the liquidity fragmentation issue.
Currently, several leading protocols within the Stacks ecosystem have begun integrating USDCx. Zest Protocol has incorporated it into its institutional-grade Bitcoin lending pools, Granite allows users to borrow USDCx using BTC as collateral, and Bitflow has launched related deep liquidity pools and trading pairs. Furthermore, major Stacks wallets such as Xverse and Leather have achieved support from day one. To optimize liquidity, the official Stacks platform encourages users who previously held aeUSDC (the older bridged USDC) to migrate to USDCx via the official Stacks bridge.
