- Justin Sun criticizes Coinbase’s cbBTC for lacking proof-of-reserve and posing security risks.
- Sun warns cbBTC allows Coinbase to freeze or blacklist user balances at any time.
- cbBTC integration could jeopardize decentralized finance, exposing users to potential government interference.
Tron founder Justin Sun has criticized Coinbase’s newly launched wrapped Bitcoin variant, cbBTC, highlighting its centralized control features that could jeopardize decentralized finance (DeFi).
Sun argues that cbBTC, designed to mirror Bitcoin on the Ethereum blockchain, lacks proof-of-reserve, independent audits, and empowers Coinbase to freeze user balances at will. He claims this poses serious risks to DeFi users. His comments came in response to a post that exposed cbBTC’s centralized nature, showing Coinbase’s ability to freeze and blacklist addresses directly through the smart contract.
Mincing no words, the crypto billionaire slammed Coinbase’s control over cryptocurrency goes against the decentralized ethos of Bitcoin and DeFi. He compared cbBTC’s centralized control to BitGo’s wrapped Bitcoin (wBTC), which lacks the capability to freeze or blacklist addresses, aligning closely with the core decentralization principles.

Sun Cautions DeFi Against cbBTC Integration
Sun also voiced strong concerns about integrating cbBTC into DeFi platforms, which could expose users to substantial regulatory risks. He warned that a single government subpoena could force Coinbase to instantly freeze all Bitcoin associated with cbBTC, undermining the entire concept of decentralization. Sun cautioned:
“Integrating cbBTC will pose major security risks to DeFi. A single subpoena could freeze on-chain Bitcoin instantly, making decentralization a joke.”
His remarks have ignited debate within the crypto community, where most echo concerns over the potential risks of centralization in a supposedly decentralized ecosystem as DeFi. The ability of a centralized entity like Coinbase to freeze assets has raised red flags, especially in a space that advocates autonomy from government or institutional control.
Sun concluded that while he is friends with many DeFi protocol founders, he would strongly advise against integrating cbBTC due to its inherent security risks. The community now faces a crucial decision to make: adopt cbBTC at the cost of decentralization, or reject it in favor of more transparent alternatives like wBTC.
