Circle to Launch cirBTC, a Regulatory-Compliant Wrapped Bitcoin on Ethereum and Arc

Circle announced cirBTC, a regulatory-first wrapped Bitcoin token that will be 1:1 backed by Bitcoin held in direct custody by Circle and issued on Ethereum and Circle’s Layer 1, Arc. The product aims to reduce counterparty risk via regular reserve attestations and Circle’s regulated money-services status, potentially attracting institutional capital and DeFi protocols that require stronger compliance assurances. Market impact could include increased liquidity for Bitcoin within DeFi, a competitive challenge to existing wrapped-BTC providers, and greater institutional participation in tokenized Bitcoin markets. Adoption by major protocols will determine its influence, but cirBTC may set a compliance precedent for future tokenized assets.
