Known Issues
2021: Cobo Vault rebranded to Keystone
The original Cobo Vault hardware-wallet team left Cobo and continued the product line as Keystone, while Cobo shifted focus away from the hardware-wallet product.
2026: Discontinued legacy support risk
Cobo Vault Pro is no longer a current official product and companion-app support is limited, so new buyers should avoid it unless they explicitly understand the unsupported legacy status.
2021: Self-destruct mechanism bypass research
Security researcher Nick Johnson described defeating the Cobo Vault Pro self-destruct mechanism under physical-analysis conditions, highlighting limits of anti-tamper claims.
