CZ Web3 security warning: Changpeng Zhao warns that even widely used open-source Web2 apps can be vulnerable and says Web3 technologies could strengthen Web2 security by enabling decentralized identity and custody solutions, while urging product teams to improve UX for inheritance and recovery features.
Meta description: CZ Web3 security warning — Changpeng Zhao urges Web3 adoption to improve Web2 security and calls for better exchange inheritance UX. Read expert takeaways.
What did CZ warn about Web3 and Web2 security?
CZ Web3 security warning states that even widely used open-source Web2 applications are susceptible to modern cyber threats. Changpeng Zhao argues that Web3 primitives — blockchain-based identity, on-chain recovery and decentralized custody — can raise the overall security baseline for Web2 systems and reduce single-point failures.
Why does CZ believe open-source Web2 software is not safe?
CZ referenced recent incidents and noted that open-source status alone does not guarantee timely security reviews or secure defaults. He stressed that vulnerabilities emerge from complex dependency chains, misconfigurations, and centralized custody models that are common in Web2 deployments.
How did CZ describe Binance’s new inheritance feature?
CZ tested Binance’s recently rolled-out mechanism that allows relatives of deceased account holders to access crypto holdings. He provided direct user feedback: the feature works functionally but needs UX improvement. He described the current experience bluntly: “Direct feedback (as a user), it (the UX) sucks. Needs improving.”

How can exchanges improve inheritance and recovery UX?
Exchanges should implement clearer documentation, multi-step guided flows, and stronger verification transparency. Recommended steps include:
- Provide step-by-step guidance and estimated timelines.
- Offer transparent verification checkpoints for families.
- Integrate on-chain proofs where applicable to avoid single-point trust.

No. Open-source code can be audited but still suffers from dependency vulnerabilities, delayed patching, and misconfiguration. CZ emphasizes that open-source status alone does not eliminate risk; process and secure-by-default settings are essential.
Web3 can complement Web2 by adding decentralized identity and custody, but it is not an immediate replacement. Integration, standards, and user-friendly UX are required before broad migration reduces systemic risk.
Changpeng Zhao’s comments reinforce a growing industry view that Web3 primitives can raise security standards for Web2 systems. Exchanges must couple technical improvements with better UX for sensitive flows like inheritance to protect users and build trust. COINOTAG will monitor updates and report on product changes.
