What does this topic help you check?
A custodial login and a wallet that gives you the keys have different recovery paths. Mobile and desktop describe where software runs. Hardware describes a separate signing device. Multisig describes a requirement for signatures, rather than a screen or device type.
Where could you start?
You want to use a phone but cannot yet explain its backup. Read the wallet-type guide, then the mobile setup guide. Pause at the backup stage until you understand how you would recover without that phone.
How do the checks fit together?
Which guides can you read now?
- Who can spend your bitcoin?
A wallet manages the keys used to spend bitcoin. Start by finding out who controls those keys, then make a recovery plan you understand.
- Which type of wallet fits you?
Start with who controls the keys and how you would recover. Then compare where you use the wallet and which checks you can realistically maintain.
- How do you set up a mobile wallet safely?
Check the source and custody model before creating anything. If you choose self-custody, make the backup privately and understand recovery before receiving funds.
- How do you set up a hardware wallet safely?
Use the documented setup for the exact device, initialise it yourself and keep the recovery information private. Check payment details on the signing device before approving.
- What does multisig protect, and what does it add?
Multisig makes spending depend on signatures from separate keys under a chosen rule. It can reduce dependence on a single key, but adds recovery records, separate backups and coordination that you must understand.
- How can you protect the devices around your wallet?
Protect the device, the accounts around it and the way you review a payment. Updates, a screen lock and careful installation habits help, while a separate backup protects against losing the device itself.
