{% hint style="info" %}
Developer support for integrating USDCx bridging into applications will be available via Circle’s Bridge Kit SDK in Q1 2026.
{% endhint %}

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?

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.

{% hint style="info" %}
For more info on xReserve, check out the dedicated Circle docs [here](https://developers.circle.com/xreserve).
