Circle, the well-known stablecoin issuer behind USDC, is making a significant move into the wrapped Bitcoin sector. In an announcement made on Thursday, the company revealed its latest product, cirBTC — a wrapped Bitcoin token designed to be backed 1:1 by BTC, set to launch on both the Ethereum network and its proprietary Arc blockchain.
Designed specifically for institutional clients, cirBTC aims to serve OTC desks, market makers, and lending protocols, enhancing access to the booming decentralized finance (DeFi) ecosystem. Circle positions cirBTC as a "highly secure and neutral version of wrapped BTC," reinforcing its commitment to security and reliability.
The purpose of wrapped Bitcoin is to facilitate the transfer of Bitcoin onto alternative blockchains, like Ethereum, enabling holders to utilize DeFi applications that are otherwise inaccessible with native Bitcoin holdings. By integrating cirBTC into Ethereum and Circle’s Arc blockchain, the token will also be supported by the Circle Mint platform, providing institutional-grade security that clients demand.
This launch marks Circle’s inaugural direct participation in the wrapped asset market, an area it has previously navigated from the sidelines despite its status as a vital infrastructure provider within the crypto space.
A Competitive Landscape Awaits
The wrapped Bitcoin marketplace is currently dominated by significant players, with BitGo’s WBTC leading the way. WBTC boasts a market capitalization of approximately $8 billion, with around 119,000 tokens in circulation — though this represents about half of its all-time highs seen in November 2021. Following closely is Coinbase’s cbBTC, launched in September 2024, which has swiftly grown to a market cap of $5.9 billion with around 88,800 tokens in circulation.
Together, WBTC and cbBTC account for roughly 208,000 BTC in total supply, according to data sourced from CoinGecko. In addition, other exchanges have introduced their own wrapped Bitcoin variants, including Kraken (kBTC), Binance (BBTC), OKX (okBTC), and Bitget (BGBTC). However, these alternatives trail significantly behind the leading tokens.
Circle enters this crowded arena with a pre-established brand and infrastructure, leaving many to wonder if cirBTC will be able to forge a distinct path and attract real institutional demand amidst the existing competition.
Bridging Institutions to DeFi with Bitcoin
As institutions worldwide increasingly accumulate Bitcoin, the challenge now lies in accessing and utilizing that capital in the expansive DeFi landscape. Wrapped tokens such as cirBTC enable institutions to tap into lending protocols, liquidity pools, and diverse DeFi infrastructures without the necessity to sell their Bitcoin holdings.
Circle has positioned cirBTC as the neutral and institutional-grade choice in this evolving pipeline, although specific details regarding custody arrangements and proof-of-reserve measures have yet to be disclosed. As inquiries continue, Circle’s lack of commentary on these vital aspects raises questions about trust and security in this new offering.
What remains evident is Circle’s intention to win the trust of institutions, mirroring the positioning strategy that propelled USDC into a leading role among stablecoins. While the launch timeline for cirBTC is yet to be confirmed, Circle has affirmed its plans to debut the token across Ethereum, Arc, and the Circle Mint ecosystem.
