Self-custody
With self-custody, you hold the means to spend bitcoin instead of an account custodian. That independence brings responsibility: you need to recognize the right address, protect backups and be able to restore the wallet.
SECSOURCE-LED TOPIC GUIDE
Connect key protection, Seed Phrase, recovery and Multisig. Distinguish technical control of funds, legal entitlement and custody’s operational risks.
You authorize spending through your own keys and script conditions. Technical ability to sign does not by itself establish legal ownership. A Seed Phrase enables recovery of derived keys in a supported format. The words are not attached to a transaction or sent to the network. Recovery requires the correct words, order, format and any passphrase. Derivation paths, address types and configuration may be needed to find all funds. Multisig can distribute signatures across devices or people. The required signature threshold and available backups determine whether you depend on another party.
Leaked words can threaten many accounts; any passphrase's strength and secrecy affect the risk. Do not invent or translate the words, or send them to support or a website requesting “verification”. Assess custody arrangements against specific threats and a verified recovery procedure. Buying a device alone does not address every way funds can be lost. Linked entries have their own sources and reviews.

The secret a wallet uses to authorize payments. How private keys work, why they must stay private, and how they differ from a PIN and recovery words.
Why a wallet shows you a list of words, what they can restore after you lose your phone, and how to keep them from helping a thief too.
A Hardware Wallet lets you approve bitcoin payments without handing your private keys to your everyday computer. It protects access to money, not money stored inside a box. Checking its screen and keeping a safe backup matter just as much as the device.
A payment need not depend on a single key. Multisig can require, for example, any two of three independent keys to sign.
A Watch-only Wallet shows incoming payments and balances and can prepare unsigned transactions. It does not hold the private keys needed to spend. An accurate view requires the complete rules of your wallet and reliable blockchain data.
