Circle Internet has officially launched its wrapped version of Bitcoin, known as cirBTC, on the Ethereum blockchain. This move marks a significant step for the company, which is primarily recognized for its dollar-pegged stablecoin, as it seeks to compete with Coinbase in the growing synthetic Bitcoin market.
CirBTC is uniquely structured, being backed at a 1:1 ratio by Bitcoin, the largest cryptocurrency by market capitalization. The token is designed to enhance access for traders looking to leverage their Bitcoin holdings within decentralized finance (DeFi) protocols. These protocols include lending platforms, decentralized exchanges (DEXs), tokenized asset systems, and other stablecoin transactions.
The emergence of synthetic or wrapped Bitcoin tokens addresses a long-standing issue: the lack of robust DeFi capabilities on the Bitcoin network. While many cryptocurrency investors prefer holding Bitcoin due to its substantial market dominance, they have faced hurdles in utilizing it for DeFi activities. This limitation arises from Bitcoin’s absence of the native programmability found in networks like Ethereum.
The first notable entry into this market was wrapped Bitcoin (wBTC), which was introduced in 2019 and currently holds the title of the largest synthetic Bitcoin token, boasting a market capitalization of approximately $7.3 billion. Following wBTC, Coinbase launched its version, cbBTC, in 2024, which has garnered a market cap just below $5.4 billion.
Circle aims to attract institutional investors with cirBTC, particularly those who focus their cryptocurrency allocations on Bitcoin. The company’s existing reputation and infrastructure within the stablecoin sector, amplified by its USDC stablecoin—which is the second-largest in the market with a cap exceeding $75 billion—provides a compelling pitch for institutions seeking to navigate the crypto landscape.
The competition surrounding synthetic Bitcoin tokens is heating up, as Circle’s entrance could intensify the rivalry not only with Coinbase but also with BitGo Holdings, the primary custodian for wBTC. As of now, the combined market capitalization of all synthetic Bitcoin tokens fluctuates between $12.5 billion and $13.5 billion, which represents roughly 1% of Bitcoin’s total market value estimated at around $1.25 trillion.
