Unlike traditional banking, where you can dispute fraudulent transactions, cryptocurrency operates under a "code is law" principle. If your wallet is compromised, the assets are gone forever. Achieving self-custody—holding your own private keys—requires treating your crypto assets with extreme security rigor.

Hardening Your Crypto Assets

1. Cold Storage is Mandatory: Large amounts of cryptocurrency should never be stored in "hot" wallets (wallets constantly connected to the internet, such as browser extensions or mobile apps). Use hardware cold wallets (physical USB-based devices) for long-term storage. These devices keep your private keys offline at all times. 2. Seed Phrase Discipline: Your "seed phrase" (12–24 words) is the master key to your entire wallet. Never store it digitally. Do not take a photo of it, do not save it in a password manager, and do not type it into a text file. Write it on a physical piece of paper or metal, and store it in a secure, fireproof location. 3. Never Share Your Seed: No customer support representative, no developer, and no official project account will ever ask for your seed phrase. Anyone asking for it is a scammer.
