cirBTC Is Now Live on Ethereum

Circle Internet Financial has launched cirBTC, a new wrapped Bitcoin (BTC) token on Ethereum that provides 1:1 BTC-backed collateral for decentralized finance (DeFi) applications, aiming to expand Bitcoin's utility across lending protocols, OTC workflows, market making, and treasury operations. By offering a secure, neutral collateral option, cirBTC allows native BTC to remain safeguarded while enabling its use in smart contract markets without needing to sell the original BTC. The token is backed by native BTC custodied at a regulated Circle entity and ensures transparency and ongoing reserve visibility through Chainlink Proof of Reserve. With Ethereum as a starting point, cirBTC is designed to integrate into Circle's broader infrastructure, including Circle Mint and USDC, and has plans for Arc and multichain support, aligning with Circle's vision of open and interoperable financial infrastructure.
