What is cbBTC?
Coinbase Wrapped BTC ("cbBTC") is a token that is backed 1:1 by native Bitcoin (BTC) held by Coinbase, meaning that for all cbBTC in circulation, there is an equivalent amount of BTC held in a secure custody solution (including cold storage) provided by Coinbase. Wrapped assets, like cbBTC, are transferable tokens that are redeemable for the underlying asset. Coinbase customers can unwrap cbBTC and redeem a corresponding amount of the underlying BTC simply by depositing the cbBTC into their Coinbase accounts. cbBTC is built to be seamlessly compatible with DeFi applications, giving customers the option to tap into DeFi and unlock financial utility.Why cbBTC?
cbBTC removes a key point of friction by allowing customers to use Bitcoin they already hold in new ways onchain. cbBTC is built to be seamlessly compatible with DeFi applications, so users can now tap into novel DeFi use cases like providing their Bitcoin as liquidity to DeFi protocols, using it as collateral to borrow other crypto assets, or spending it as a payment method. Wrapped assets like cbBTC are a mature concept in the crypto world, helping to bring more liquid assets onchain and facilitate an expansive financial ecosystem.Minting and Burning Process
cbBTC is fungible 1:1 with a dedicated reserve of BTC held at Coinbase. The process of minting (sending) and burning (redeeming) cbBTC ensures trust and transparency, providing a frictionless experience for users. When a user requests a withdrawal of cbBTC, Coinbase holds the corresponding amount of BTC in its custody to back the cbBTC minted.- Minting: When a user initiates a withdrawal of BTC held in their Coinbase account to the Ethereum or Base networks, an equivalent amount of cbBTC is minted on the network and sent to the user’s destination address / wallet.
- Burning: When cbBTC is deposited to a user-specific Coinbase address, the cbBTC is burned and the corresponding amount of BTC is released from Coinbase’s reserve and assigned to the user’s Bitcoin account.
The total supply of cbBTC can be found in the token smart contract under totalSupply.
The process of minting and burning cbBTC involves using a set of audited and secure Ethereum smart contracts. These contracts are designed to mint and burn cbBTC as needed, ensuring that the total supply of cbBTC always matches the amount of BTC held backing it. cbBTC is built using the core elements of the Coinbase wrapped token contract that was also used for Coinbase Wrapped Staked ETH (cbETH). The smart contract code open source repository for Coinbase's wrapped tokens – including both cbBTC and cbETH – can be found on Github.
The following are key roles of the wrapping contract managed by Coinbase. These roles are protected by Coinbase’s key management systems and usage requires approval from a number of people in different functions, including security, engineering, and finance.
* Admin: can upgrade the wrapped token implementation contract
* Owner: can assign all roles except the Admin
* Blacklister: can blacklist an address from transferring, minting, and burning
* MasterMinter: can assign minters and their limits
* Minter: can mint and burn tokens
* Pauser: can pause transfers, mints, and burns for the contract
Security Measures and Compliance
Coinbase employs state-of-the-art wallets, regular audits, and comprehensive monitoring systems to safeguard the BTC backing cbBTC. Additionally, all smart contracts involved in the minting and redemption process are rigorously tested and audited by third-party security experts.Coinbase engaged OpenZeppelin in an audit of the cbETH smart contract contract which was also used for cbBTC. No material contract code has been modified in deploying cbBTC.
Custodianship and Governance
The underlying BTC reserves backing cbBTC are held 1:1 at Coinbase, and redemption rights remain with cbBTC holders. Please reference the applicable Coinbase User Agreement to learn more about Coinbase’s custodial services and terms specific to users holding cbBTC.Coinbase utilizes both hot wallets and cold wallets in its custodial solutions. Cold wallet private key materials are stored and secured at facilities within the United States and Europe. As part of Coinbase’s risk mitigation efforts, wallet private keys are not stored in plaintext format in any location and the cryptographic consensus of multiple human operators is required to decrypt a private key for both hot and cold wallets. No single individual has control of Coinbase’s wallet private keys. Coinbase performs internal audits of the private key management process and reconciliations between Coinbase wallets and third-party blockchain data. Coinbase does not use sub-custodians in connection with the storage of digital assets.
