Coinbase Launches ‘cbBTC’ Wrapped Bitcoin Digital Asset
Coinbase Introduces cbBTC
Coinbase has launched its new cbBTC token, a wrapped version of Bitcoin on the Ethereum network and its own layer-2 scaling network, Base. The exchange announced that the cbBTC token is now available in the United Kingdom, Australia, Singapore, and all US states except New York.
How cbBTC Works
The cbBTC token is backed 1:1 with Bitcoin held by Coinbase. When a user sends Bitcoin to a Base or Ethereum address, cbBTC is automatically minted at a 1:1 ratio. Conversely, if a user sends cbBTC to a Coinbase address, it converts back to standard Bitcoin. This token has no separate order book or trading pairs on the exchange’s platform.
Expansion Plans
Coinbase plans to expand cbBTC to other blockchain networks and ecosystems in the future, though no specific details have been provided yet.
Purpose of cbBTC
Tokenized versions of Bitcoin, like cbBTC, enable decentralized finance functionalities for Bitcoin. The Bitcoin ledger consists of unspent transaction outputs (UTXO), and Bitcoin wallets contain collections of these outputs assigned to particular addresses. Due to this structure, transferring Bitcoin between different blockchain networks is challenging, limiting its use in decentralized finance (DeFi) applications. These applications predominantly exist within the Ethereum ecosystem.
Uses of cbBTC in DeFi
Coinbase’s cbBTC allows users to use their Bitcoin as collateral to secure loans or as a lending asset that accrues yield. At launch, cbBTC will be supported on several DeFi platforms, including Aave, Compound Finance, Morpho, Spark, and Moonwell.
BitGo’s Wrapped Bitcoin Controversy
Coinbase announced the launch of cbBTC shortly after BitGo faced criticism for changing the custodial structure of its Wrapped Bitcoin (WBTC) product. BitGo’s new structure involves multiple jurisdictions, including Hong Kong and Singapore, and has drawn concern due to the involvement of Tron founder Justin Sun. Risk management firm Block Analitica suggested restricting all WBTC positions, citing Sun’s involvement as a significant risk.
Conclusion
Coinbase’s introduction of cbBTC aims to bring more flexibility and utility to Bitcoin within the DeFi space. By enabling Bitcoin to be used as collateral and in lending applications, Coinbase seeks to integrate Bitcoin more deeply into decentralized finance, potentially expanding its use case and adoption across various blockchain networks.
