Coinbase Wrapped BTC (CBBTC)

Coinbase Wrapped BTC (CBBTC) is a digital token representing real Bitcoin held in custody by the exchange Coinbase. Each CBBTC is backed one-for-one by actual BTC, functioning as a claim ticket that allows Bitcoin to operate on blockchains where the native asset cannot travel. This mechanism enables the use of Bitcoin within decentralized finance applications and other networks not originally built to understand Bitcoin itself.

Technology and Use Cases

• Wrapped Token Mechanism: CBBTC acts as a voucher for physical Bitcoin, similar to a paper receipt for a gold bar stored in a vault.
• Network Compatibility: It facilitates movement across various blockchain ecosystems beyond the original Bitcoin network.
• DeFi Integration: Allows users to leverage Bitcoin in complex money apps and protocols designed for other cryptocurrencies.
• Redemption Capability: Holders can return the token to the vault to retrieve the underlying Bitcoin asset.

First market data for this asset was recorded in 2024. The token simplifies Bitcoin's utility by separating the asset's storage from its circulation, addressing the limitations of Bitcoin's original network design which prioritizes security over application complexity.
