Self-custody & wallets

Not your keys, not your coins — still true. This pillar is about habits and hardware classes, not hype launches.

What self-custody actually means

Self-custody means you (or a carefully designed multisig set) control the private keys that authorize spends. An exchange balance is an IOU. A browser extension can be self-custodial and still be a phishing magnet. Clarity beats branding.

Seed hygiene (non-negotiable)

  • Generate seeds offline when using hardware; never type a seed into a website “to sync” or “to claim.”
  • Write backups on durable media. Avoid cloud photos, email drafts, and password managers as the sole copy of a seed.
  • Test recovery on a spare device before you fund anything meaningful.
  • Passphrases add power and foot-guns. Document your scheme for heirs without putting the seed in the same place as the passphrase.

Software vs hardware

Hot wallets are for amounts you can afford to lose to malware. Hardware wallets keep signing keys off the networked OS. They are not magic: supply-chain risk, fake firmware prompts, and social engineering still apply. Buy from official channels; verify packaging and device authenticity steps from the vendor.

Operational split

Many practitioners keep a small hot wallet for daily experiments and a cold path for savings. We do not prescribe ratios — only the principle: reduce the blast radius of any single mistake. CryptoDecentral does not custody assets or recover seeds.
