Wrapped Tokens: Unlocking New Uses for Bitcoin and Beyond

?? Happy Friday! The past week has been eventful, with Bitcoin rising 10% following the Fed’s 50bps rate cut and the successful launch of cbBTC, Coinbase’s new wrapped Bitcoin token, which has soared to over $120 million in market cap within just a few days. These developments highlight the growing demand for Bitcoin in DeFi and the opportunities that wrapped tokens offer in expanding Bitcoin’s utility across decentralized ecosystems like Ethereum and Base.

?? What Are Wrapped Tokens?

Wrapped tokens, such as WBTC, tBTC, and cbBTC, address Bitcoin’s lack of smart contract functionality by converting BTC into an ERC20 token, allowing holders to participate in DeFi activities like lending, borrowing, and staking. Despite the vast potential of this market, only a small percentage of Bitcoin is currently wrapped. This is largely due to Bitcoin holders preferring to keep BTC as a store of value, concerns about security when moving assets off the Bitcoin network, or lack of awareness about DeFi opportunities.

?? The Importance of DeFi and Bitcoin

DeFi offers decentralized financial services without intermediaries, but Bitcoin's native network is limited in interacting with these platforms. Wrapped Bitcoin tokens enable BTC holders to access decentralized applications, making Bitcoin more versatile across DeFi platforms.

?? The Key Wrapped Bitcoin Options

1. WBTC: With over $9 billion in circulation, Wrapped Bitcoin (WBTC) is the most popular wrapped BTC token. It offers deep liquidity but faces criticism for its centralized custodianship.
2. tBTC: Offering a decentralized, trust less model, tBTC has a market cap of $230 million. It’s favoured by those seeking decentralization, relying on a network of validators and smart contracts.
3. cbBTC: Launched by Coinbase in 2024, cbBTC quickly reached $100 million in market cap within 24 hours. Backed 1:1 by Bitcoin held in Coinbase custody, cbBTC integrates with both Base and Ethereum, offering a more regulated and transparent option for DeFi users.

?? Why Was cbBTC Introduced?

Coinbase introduced cbBTC to capture the growing demand for secure, trusted Bitcoin participation in DeFi. The following are key drivers:

1. Underutilised Bitcoin in DeFi: Less than 1-2% of Bitcoin is currently wrapped and utilized in DeFi, leaving over $1 trillion of potential liquidity untapped. Many Bitcoin holders are either unaware of DeFi opportunities or prefer to hold BTC as a store of value on its native chain due to its status as the most secure blockchain. Concerns about DeFi security and custodial risks also contribute to the reluctance to wrap BTC.
2. Base Success: Coinbase’s Base Layer 2 network has rapidly emerged as one of the top solutions, ranking in the top 1-2 for transaction volume, total value locked (TVL), developer activity, and active user base. Impressively, this growth has occurred within its first year. Base recently set a record with 4.5 million transactions in a single day, highlighting its increasing traction with dApps and DeFi projects. cbBTC enhances Base’s ecosystem by introducing Bitcoin liquidity, boosting its scalability and DeFi capabilities
3. A Trusted Alternative: WBTC, while dominant, has raised concerns about centralization. cbBTC offers a regulated alternative, appealing to those who prioritize security and transparency.

?? Alternatives to Wrapped Bitcoin

In addition to wrapped Bitcoin tokens, emerging solutions are beginning to offer alternatives for Bitcoin’s use in decentralized applications:

1. Ordinals and Runes: Allow users to inscribe data or add smart contract-like features to the Bitcoin blockchain. Though early-stage, these developments could expand Bitcoin’s DeFi potential.
2. BRC-20 Tokens: Based on Ethereum’s ERC-20 standard, BRC-20 tokens bring fungibility to Bitcoin, but they are still in their infancy compared to Ethereum-based DeFi.
3. Bitcoin Layer 2 Solutions: Technologies like the Lightning Network provide faster, cheaper transactions, but are currently less suited for DeFi compared to Ethereum.

Risks and Considerations for Wrapped Assets

1. Centralization: Wrapped tokens like WBTC rely on centralized custodians, which introduces trust risks. If the custodian is compromised, assets could be lost.
2. Custodial Risk: When moving Bitcoin off its native chain, users must trust third-party platforms to securely hold their assets, creating potential vulnerabilities.
3. Smart Contract Risks: Wrapped tokens rely on smart contracts, which could contain bugs or be exploited, leading to potential losses.
4. Liquidity Risk: Not all wrapped assets have the same level of liquidity, which may affect users' ability to easily trade or use them in DeFi.

Understanding these risks and using audited, reputable platforms can help mitigate potential issues.

cbBTC represents a positive development for the crypto industry, providing users with a secure, compliant choice for engaging Bitcoin in DeFi. Just as Coinbase’s history with USDC, co-launched with Circle , helped USDC grow to a $35 billion market cap by offering a regulated alternative to USDT, cbBTC is expected to follow a similar path. With Coinbase’s trusted infrastructure and transparency, cbBTC brings liquidity to Base and Ethereum, offering users another robust option for leveraging their Bitcoin in decentralized finance.
