CZ releases crypto asset custody guide, advises choosing custody methods based on asset size and technical capabilities.

Binance founder CZ has released a simplified crypto asset custody guide, advising users to match security measures based on their own holdings size and technical capabilities, with a focus on three key issues: preventing asset theft, avoiding accidental loss, and planning for asset inheritance in advance. For self-custody, CZ recommends users store private keys on offline devices, use reliable hardware wallets, verify transaction addresses, and set up multiple off-site backups. He also warns users against saving keys via photos or screenshots to prevent leaks from syncing to cloud storage. Regarding asset inheritance, users should develop a secure recovery plan in advance, avoiding direct sharing of keys or storing recovery information in unencrypted form. For centralized trading platforms, CZ advises users to evaluate the platform’s reputation, security capabilities, and business model, and strengthen account protection through measures such as independent email addresses, strong passwords, two-factor authentication, hardware security keys, and withdrawal address whitelisting. He also cautions users to be wary of phishing attacks and API credential leaks. CZ further suggests that users allocate their assets reasonably between centralized trading platforms and personal wallets based on their technical capabilities, security management level, and fund usage needs. Self-custody means users bear sole responsibility for protecting private keys and asset recovery, while platform custody involves platform credit and counterparty risks. Additionally, maintaining an independent wallet helps preserve access to assets during platform maintenance or service interruptions.
