Stacks officially launches USDCx, introducing native institutional-grade dollar liquidity for Bitcoin L2

Stacks has officially announced the launch of USDCx. This is a stablecoin backed by USDC, based on Circle's new xReserve infrastructure. The launch of USDCx establishes a native and institution-grade liquidity dollar channel for the Bitcoin Layer 2 ecosystem, allowing funds to settle directly on the Bitcoin network.

On the technical side, USDCx is issued through Circle's 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 addressing the issue of liquidity fragmentation.

Currently, several leading protocols within the Stacks ecosystem have begun integrating USDCx. Zest Protocol has incorporated it into its institution-grade Bitcoin credit funding pool, Granite allows users to borrow USDCx using BTC as collateral, while Bitflow has launched related deep liquidity pools and trading pairs. Additionally, mainstream Stacks wallets such as Xverse and Leather have implemented support from day one. To optimize liquidity, the official team encourages users who originally held aeUSDC (the old bridged USDC) to migrate to USDCx via the Stacks official bridge.
