Proton Wallet is a Bitcoin wallet designed around self-custody. In a self-custody setup, the user—not the provider—ultimately controls the keys required to authorize spending.
Self-custody transfers responsibility
A provider cannot normally restore funds without the user’s recovery material. Device security, backups, address verification, updates, and careful transaction review become part of the user’s job.
The wallet application is an interface to keys
Owning Bitcoin does not mean coins are stored inside the app; keys authorize changes recorded by the network.
Recovery should be tested before it is needed
Backups should be stored away from everyday devices and protected from disclosure, damage, and loss. Users should follow the wallet’s current recovery instructions rather than improvising a format.
Support should never need the recovery phrase
A request to reveal recovery words is a strong warning sign because those words can authorize wallet restoration.
