About
We built the tracker we wanted to use ourselves.
Most crypto portfolio trackers ask for an account, an email, or worse – identity documents – just to show you your own wallet balances. That never made sense to us.
21stealth is different. We built it for crypto holders of all kinds: traders who move between chains, long-term holders with cold wallets, and anyone who simply wants to know what their portfolio is worth – without handing over personal data.
We store nothing on our servers. Your data belongs to you: exportable, encrypted, and fully portable.
21stealth is open source, live, and free to use.
