What is BC Vault
BC Vault is a seedless hardware wallet made in Slovenia, introduced in October 2018 by REAL security and since 2024 produced by the spin-off REAL BCV d.o.o. Instead of a seed phrase it keeps encrypted private keys in FRAM memory and backs them up as encrypted microSD or QR-code files; it connects by USB cable to desktop and mobile apps.

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
