Hardware Wallets and Self-Custody Basics

A hardware wallet is the standard tool for this. It stores your private keys offline on a dedicated device, so even a compromised computer cannot extract them; transactions are signed on the device itself. The trade-off is that you become your own bank, with no password reset and no support line that can recover lost funds.

That responsibility is where people fail, so the basics matter enormously. Your recovery phrase (seed) is the master key — anyone who has it controls your funds, and no one who lacks it can help you. Write it on paper or metal, never photograph it, never type it into a website, and store backups securely offline. Buy hardware only from the manufacturer or an authorised reseller, never second-hand. The most common total losses are not hacks — they are lost seed phrases and phishing, both covered in our crypto security guide.

Self-custody is the counterweight to the platform risks we cover in crypto lending risks and choosing an exchange. Many people sensibly keep trading funds on an exchange and long-term holdings in self-custody.

Hold your own keys for what you cannot afford to lose, and protect the seed above all else. Capital at risk; lost keys are unrecoverable. This is not financial advice.
