How xReserve works

Deposit-and-mint

Once USDC is deposited into the Circle-deployed xReserve contract, the xReserve API verifies the deposit and issues an attestation. Partner blockchains retrieve this attestation and use it to mint USDC-backed tokens on its network.

Burn-and-mint

A user initiates a cross-chain transfer by submitting a burn request for USDC-backed tokens on the partner blockchain. The blockchain team processes the request and submits a withdrawal to xReserve, where the xReserve API verifies the burn and signs an attestation. The destination blockchain team or a third party then uses this attestation to mint USDC or USDC-backed tokens for the user. Minting can also be automatically triggered by Circle's upcoming forwarding service.
