Self-Custody
What it means to hold your own bitcoin keys, what self-custody protects you from and what it asks of you in return.
Bitcoin self-custody means holding the private keys to your own bitcoin instead of leaving them with an exchange or another company. Whoever controls the keys controls the coins, which is why this is the central question behind storing bitcoin safely. The Power of Self-Custody covers hardware wallets, seed phrases, multisig and inheritance, and How to Buy and Secure Bitcoin covers the first practical steps. Bitcoin Wallets Explained helps you choose a wallet, and What Is a Seed Phrase? covers the recovery words. Bitcoin Cold Storage Explained and Bitcoin Multisig Explained go further, and What Happens to Lost Bitcoin? shows why backups matter.
Self-custody removes the risk of an exchange failing or freezing your account, but it replaces that with the risk of lost backups and mistakes, and there is no customer support for a lost seed phrase. If you are new to Bitcoin, begin with Start Here, and see the Security category for related guides. How to Send and Receive Bitcoin Safely covers moving coins in and out of a wallet. What Is a Hardware Wallet? explains the device many people use for it. To choose a device, compare the main options in Best Bitcoin Wallets and Ledger vs Trezor. How to Store Bitcoin helps you choose a storage method.

Frequently asked questions about Self-Custody
What does self-custody mean in Bitcoin?
Self-custody means you hold the private keys that control your bitcoin, instead of an exchange or other company holding them for you. No company can freeze or lose coins it never had, but there is also nobody to call if you lose access. The Power of Self-Custody explains the trade in detail.
What does "not your keys, not your coins" mean?
It means that when an exchange holds your keys, you hold a claim on the company rather than the coins themselves, and that claim is only as good as the exchange's honesty, solvency and security. Several large exchanges have frozen withdrawals or failed. Holding your own keys avoids that risk but adds personal responsibility, as the self-custody guide explains.
What is a seed phrase and how should I store it?
A seed phrase is typically 12 or 24 ordinary words that can rebuild every key in your wallet, so anyone who sees it can take your bitcoin. Write it on paper or metal, keep it offline and never photograph it or type it into a website. No legitimate support agent will ask for it. See How to Buy and Secure Bitcoin.
Is a hardware wallet safer than leaving bitcoin on an exchange?
A hardware wallet keeps your keys on a dedicated device, so malware on your computer generally cannot spend the coins without it. That removes exchange risk but adds others, such as a lost backup or a tampered device bought from a reseller. Which is safer for you depends on the amount and your comfort with the process. See the self-custody guide.
What happens to my bitcoin if I die?
If you are the only person who can access your bitcoin, your family may not be able to recover it, because no company holds it and no probate process can force one to hand it over. Options include written instructions with a lawyer or a multisig setup with a trusted key holder. Estate rules vary by state, so ask an estate attorney. See the self-custody guide.
What is a multisig wallet?
A multisig wallet needs more than one key to approve a payment, for example any two of three keys. That removes the single point of failure, so losing or leaking one key is not fatal. The cost is complexity, including extra backups of the wallet setup. See Bitcoin Multisig Explained.
