CoinVoice has learned that Stacks officially launched USDCx. This is a stablecoin supported by USDC and based on Circle's new xReserve infrastructure. The launch of USDCx establishes a native and institution-grade dollar channel with liquidity for the Bitcoin Layer 2 ecosystem, allowing funds to settle directly on the Bitcoin network.
On the technical underlying side, USDCx is issued through Circle xReserve's non-custodial smart contracts, providing cryptographic proof to ensure token transparency. At the same time, this 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 the security risks of third-party bridges and solving the problem of liquidity fragmentation.
Currently, several leading protocols within the Stacks ecosystem have begun integrating USDCx. Zest Protocol has incorporated it into an institutional-grade Bitcoin credit funding pool, Granite allows users to borrow USDCx against BTC as collateral, while Bitflow has launched related deep liquidity pools and trading pairs. In addition, mainstream Stacks wallets like Xverse and Leather have achieved first-day support. To optimize liquidity, the official team encourages original holders of aeUSDC (the old version of bridged USDC) to migrate to USDCx via the official Stacks bridge. [Original link]
