# USDCx

USDCx is a 1:1 USDC-backed stablecoin issued through Circle xReserve and native to Stacks.

Stacks now has a fully USDC-backed stablecoin that plugs directly into Circle’s multichain ecosystem and brings stable, interoperable dollar liquidity to Bitcoin’s leading Layer 2.

#### What is USDCx? <a href="#what-is-usdcx" id="what-is-usdcx"></a>

USDCx is a 1:1 USDC-backed stablecoin issued through Circle xReserve and native to Stacks. It will exist as a SIP-010 token on Stacks.

Circle's xReserve provides cryptographic attestations for deposits and minting, while Circle Gateway and CCTP handle cross-chain movement. The result is USDC on Stacks without third-party bridges, wrapped assets, or fragmented liquidity.

For more info on xReserve, check out the dedicated Circle docs [here](https://developers.circle.com/xreserve).

\
The USDCx Bridge app is maintained by Stacks Labs and is powered by Circle xReserve.

> Acquire USDCx through the [official bridge app](https://bridge.stacks.co/) or migrate your aeUSDC into USDCx to take advantage of better liquidity and improved trust assumptions.

Additionally, users can bridge to USDCx from a variety of cross-chain stablecoins by using the [Allbridge Core](https://core.allbridge.io/pools) stableswap protocol.&#x20;
