Self-Custody Basics

A practical starter deck for holding keys, avoiding common mistakes, and building confidence slowly.

Why self-custody matters

  • Bitcoin lets you hold money without relying on a custodian.
  • That power comes with operational responsibility.
  • The goal is not paranoia; the goal is reducing single points of failure.

Start small

  • Use a wallet you understand.
  • Practice receiving and sending modest amounts.
  • Write down the recovery words and test the restore process.
  • Keep learning before increasing balances.

Backups

  • A seed phrase controls the funds.
  • A lost seed can mean permanent loss.
  • A leaked seed can mean theft.
  • Store backups somewhere private, durable, and recoverable.

Hardware wallets

  • Hardware wallets keep signing keys isolated from your laptop or phone.
  • They are useful once balances justify the extra ceremony.
  • The device is replaceable; the seed backup is what matters.

Good next steps

  • Learn the difference between hot and cold storage.
  • Understand single-sig before jumping to multisig.
  • Keep notes about your setup that a future version of you can understand.
