xReserve is an interoperability infrastructure that lets blockchain teams deploy USDC-backed stablecoins on their own blockchains. It is powered by programmatic attestations and Circle-deployed smart contracts that hold USDC in reserve on source blockchains such as Arc and Ethereum. USDC-backed stablecoins deployed through xReserve are interoperable with each other and with the broader USDC network.

Key benefits

xReserve benefits blockchains, developers, and end users:
  • Day 1 liquidity: Tokens created using xReserve are connected to the broader USDC network, allowing users to move tokens across blockchains.
  • Interoperability: Users can make 1:1 transfers between USDC-backed stablecoins and USDC.
  • Deployed by Circle: xReserve holds USDC in a smart contract deployed by Circle.
  • Minimized trust assumptions: xReserve attesters verify deposits and burns, reducing reliance on third-party services to convert USDC.
