The cryptocurrency landscape continues to evolve as major players innovate to expand Bitcoin’s utility across alternative blockchains. Coinbase, one of the leading digital asset exchanges, is reportedly developing cbBTC—a native wrapped Bitcoin solution designed specifically for Base, its Ethereum layer-2 blockchain. This move signals a strategic effort to deepen Bitcoin integration within the Base ecosystem and offer users seamless access to the world’s largest cryptocurrency by market cap.
What Is cbBTC?
While official documentation is still emerging, early signals suggest that cbBTC will function similarly to existing wrapped Bitcoin tokens like wBTC, allowing Bitcoin (BTC) to be used on non-native blockchains. In this case, cbBTC would enable BTC holders to interact with decentralized applications (dApps), lending protocols, and decentralized exchanges (DEXs) built on Base.
Wrapping BTC involves locking the original Bitcoin in a secure custodial reserve and issuing a 1:1 pegged token on another blockchain—in this case, Base. When users wish to redeem their BTC, the wrapped version is burned, and the original asset is released.
This mechanism enhances liquidity, interoperability, and utility of Bitcoin beyond its native chain, aligning with broader industry trends toward multi-chain asset usage.

Why Base Needs cbBTC
Base, launched by Coinbase in 2023, has rapidly gained traction as a developer-friendly Ethereum layer-2 scaling solution. Built using the OP Stack, Base aims to onboard millions of new users to web3 by offering low transaction fees and high security through Ethereum’s consensus layer.
Despite its growth, Base has lacked deep Bitcoin integration—until now. Introducing cbBTC could catalyze a Bitcoin-centric economy on Base, enabling:
- Yield-generating opportunities via Bitcoin-backed lending and staking-like strategies
- Cross-chain decentralized trading with BTC as collateral
- Enhanced liquidity for Bitcoin within Base-native DeFi protocols
- Greater adoption among Bitcoin maximalists who prefer using BTC across ecosystems
Jesse Pollak, the founder of Base and former head of protocol at Coinbase, reinforced this vision in a recent post on X (formerly Twitter), stating:
"to say it out loud: I love bitcoin, am so grateful for it's role kickstarting crypto, and we're going to build a massive bitcoin economy on @base."
This public endorsement underscores a clear strategic pivot: Base is positioning itself not just as an Ethereum L2, but as a hub for Bitcoin innovation.
The Context: Challenges Facing wBTC
Coinbase’s move comes at a pivotal moment for wrapped Bitcoin as a category. wBTC, the dominant wrapped BTC token with over $7 billion in total value locked (TVL), recently faced scrutiny following BitGo’s announcement of a joint venture with BiT Global, a Hong Kong-based custody platform partially linked to Tron founder Justin Sun.
Although BitGo emphasized that:
- wBTC’s multisignature security model remains unchanged
- All BTC reserves are still verifiable on-chain
- No operational control was transferred to external parties
Concerns emerged within key DeFi communities. Notably, MakerDAO—a major player in decentralized finance—proposed reducing wBTC’s debt ceiling to zero DAI and halting borrowing against wBTC collateral. The proposal cited potential jurisdictional and governance risks tied to the new custody arrangement.
Despite these concerns, on-chain data from Dune Analytics shows no significant outflow from wBTC reserves, indicating that market participants have not yet reacted with mass redemptions.

How cbBTC Could Address Market Gaps
With trust becoming an increasingly critical factor in crypto custody models, cbBTC presents an opportunity for Coinbase to position itself as a more transparent and trusted alternative—especially given its regulated status as a publicly traded U.S. company.
Potential advantages of cbBTC may include:
- Direct custody by Coinbase Custody, a regulated custodian
- Real-time reserve attestations and audit transparency
- Native integration with Base’s growing DeFi stack
- Alignment with Coinbase’s broader mission of increasing crypto accessibility
If cbBTC offers stronger regulatory clarity and institutional-grade security assurances, it could attract both retail and institutional investors wary of third-party custody risks associated with other wrapped tokens.
Moreover, because Base is fully integrated into Coinbase’s ecosystem—including its wallet, exchange, and developer tools—user onboarding could be significantly smoother than competing solutions.
The Road Ahead for Bitcoin on Layer 2
The development of cbBTC reflects a broader trend: Bitcoin is no longer confined to its native chain. From Lightning Network payments to layer-2 wrapping solutions like wBTC, Stacks, and now potentially cbBTC, developers are finding innovative ways to extend Bitcoin’s reach.
As Ethereum layer-2 adoption accelerates, having native BTC exposure becomes essential for DeFi platforms aiming to capture value from Bitcoin’s $1 trillion+ market cap. By launching cbBTC, Coinbase isn’t just adding another token—it’s laying the foundation for a multi-chain Bitcoin future, where BTC can generate yield, power smart contracts, and fuel innovation beyond simple peer-to-peer transfers.
Frequently Asked Questions (FAQ)
Q: What is cbBTC?
A: cbBTC is a rumored wrapped Bitcoin token being developed by Coinbase for use on its Base blockchain. It would allow Bitcoin holders to use BTC in DeFi applications on Base through a 1:1 pegged representation.
Q: How does cbBTC differ from wBTC?
A: While both are wrapped Bitcoin tokens, cbBTC would be natively supported by Coinbase and potentially custodied by its regulated arm, offering greater transparency and integration with the Base ecosystem compared to wBTC’s current custody structure.
Q: Is cbBTC officially launched yet?
A: As of August 2024, cbBTC has not been officially launched. Announcements from Coinbase and Jesse Pollak suggest it is in development with a “coming soon” timeline.
Q: Can I redeem cbBTC for real Bitcoin?
A: If cbBTC follows standard wrapping mechanics, yes—users should be able to burn their cbBTC tokens and receive an equivalent amount of BTC from the custodial reserve.
Q: Why is Base focusing on Bitcoin now?
A: Despite being an Ethereum L2, Base aims to build a robust DeFi ecosystem. Integrating Bitcoin increases liquidity options and appeals to a wider user base, including Bitcoin-focused investors seeking yield opportunities.
Q: Will cbBTC compete with wBTC?
A: It has the potential to become a strong competitor, especially if it offers superior transparency, lower fees, or deeper integration with popular Base-based dApps.

Final Thoughts
Coinbase’s rumored launch of cbBTC marks a significant step toward unifying two of crypto’s most powerful networks: Bitcoin and Ethereum layer-2s. By bringing native BTC utility to Base, Coinbase could unlock new financial primitives, drive deeper DeFi adoption, and strengthen its position as a leader in blockchain infrastructure.
As the lines between blockchains continue to blur, wrapped assets like cbBTC will play a crucial role in shaping an interconnected, multi-chain future. For developers, investors, and everyday users alike, the integration of Bitcoin into scalable ecosystems like Base represents not just convenience—but opportunity.
With trust, transparency, and ecosystem synergy at its core, cbBTC could become the preferred bridge between Bitcoin and Ethereum’s expanding layer-2 frontier.
