## Self-Custody Security Best Practices

Self-custody security best practices are the industry-standard guidelines for individuals managing their own private keys. These include using hardware wallets, creating multiple physical backups, using strong passphrases, and keeping software updated.

The core principle is to minimize the exposure of keys to any online or untrusted environment. Users are also advised to use multisig setups for larger holdings to eliminate single points of failure.

Continuous education on emerging threats, such as phishing or malicious browser extensions, is essential for maintaining a high security posture. These practices are the foundation of true financial sovereignty.

By following these guidelines, users can significantly reduce the risk of asset loss and theft. It is a proactive approach to personal financial security.
