EXTRA SAFE mobile wallet is built for daily use. For large holdings, EXTRA WALLET – the companion web wallet with offline mode – gives you a more controlled environment for managing significant amounts without switching to a third-party tool.
The short answer: it depends less on the wallet and more on how you store your recovery phrase and how secure your device is.
EXTRA SAFE is fully non-custodial – your private keys never leave your device, every transaction is signed locally, and no third party has access to your funds. From a cryptographic standpoint, that's a solid foundation regardless of the amount. The practical risk factors with any mobile wallet are physical: a compromised device, a stolen backup phrase, or a phone without a strong lock screen.
A reasonable way to think about it:
Mobile wallet (EXTRA SAFE) – well-suited for funds you actively use: sending to contacts, paying for things, managing stablecoin balances day to day. Convenient by design, always accessible.
Web wallet (EXTRA WALLET at extrawallet.app) – the better environment for larger holdings. Same cryptographic identity, same backup phrase, but accessed from a desktop browser where you have more control over your environment. EXTRA WALLET also supports an offline mode – you can review balances and prepare transactions without an active connection, which reduces exposure during sensitive operations. For significant amounts you want to manage deliberately rather than on the go, this is the natural choice.
Both wallets are secured by the same 12-word recovery phrase. You don't need a separate account – EXTRA WALLET is the desktop expression of the same self-custodial identity you already have in EXTRA SAFE.
Whatever amount you hold, the security of your recovery phrase matters more than anything else. Written down, stored offline, never in a screenshot or cloud document – that's the foundation everything else rests on.
