In the ever-evolving cryptocurrency landscape, Bitcoin’s dominance remains a constant. As of October 16, 2024, Bitcoin’s market dominance stood at 58.70%, underscoring its status as the preferred choice for many newcomers in the crypto space. Despite the emergence of new narratives and technologies, Bitcoin, often referred to as ‘digital gold,’ continues to hold its ground.
However, Bitcoin’s steadfastness comes with certain limitations, particularly in programmability and interoperability. These constraints have led to fewer applications like decentralized finance (DeFi) and Layer 2 solutions within the Bitcoin ecosystem, resulting in limited earning opportunities. To address these challenges, wrapped Bitcoin has emerged as a viable solution, enabling Bitcoin holders to engage in DeFi activities by using tokenized versions of Bitcoin on other blockchains.
Wrapped Bitcoin: Bridging Bitcoin with DeFi
Wrapped Bitcoin is a tokenized version of Bitcoin that operates on other blockchains, such as Ethereum. By locking an equivalent amount of Bitcoin in a secure reserve, an ERC-20 token is minted to represent the original Bitcoin. This allows Bitcoin holders to participate in DeFi activities, such as lending, borrowing, and trading, without using the Bitcoin network directly. Wrapped Bitcoin effectively bridges Bitcoin’s liquidity with the flexibility of other blockchain ecosystems.
The first wrapped Bitcoin (WBTC) was introduced by BitGo in 2019. Since then, several exchanges and entities, including Huobi (HBTC), Ren Protocol (renBTC), and tBTC, have launched their versions. Recently, Coinbase became the second major centralized exchange to issue a wrapped Bitcoin token, cbBTC, on September 12, 2024. With over 110 million verified users, Coinbase holds the largest Bitcoin reserves among centralized exchanges, exceeding 820,000 BTC, valued at over $55 billion.
cbBTC: Expanding Bitcoin’s Reach
Within a week of its launch, cbBTC surpassed Huobi BTC and renBTC to become the third most popular wrapped Bitcoin product, according to CryptoQuant. By October 16, cbBTC’s total supply reached 5,915.94 tokens, valued at approximately $398 million, with 21.3% on Coinbase’s Base network and 78.7% on Ethereum.
cbBTC, or Coinbase Wrapped Bitcoin, is an ERC-20 token that represents Bitcoin in a 1:1 ratio. It allows Bitcoin holders to participate in DeFi ecosystems, particularly on Ethereum and Base, without moving their actual Bitcoin. Users can easily convert their Bitcoin to cbBTC by transferring BTC from their Coinbase accounts to Base or Ethereum addresses, where it is automatically tokenized. The reverse process is equally seamless, with no fees for creating or redeeming cbBTC, though standard network fees apply when withdrawing funds from Coinbase.
Despite its advantages, cbBTC has faced criticism for its centralized nature and lack of transparency around reserves. Concerns have been raised about Coinbase’s control over the custodial reserves of Bitcoin that back cbBTC, with some labeling it as ‘central bank Bitcoin.’ Coinbase’s chief legal officer, Paul Grewal, addressed these concerns, confirming that Coinbase would fully reimburse clients if the underlying Bitcoin were lost, though this does not cover losses from complex trades or leveraged positions using cbBTC as collateral.
Coinbase has announced plans to integrate cbBTC into the Solana ecosystem, aiming to facilitate Bitcoin’s integration with high-performance public blockchains. This expansion reflects the growing demand for making Bitcoin more accessible across multiple blockchain environments, potentially increasing its interoperability within decentralized finance ecosystems.
