Frost is the entry edition of XColdPro: it turns a USB drive into an offline cold wallet, so you can create a wallet or import a seed, then send and receive across 22+ networks from a machine that stays offline. Recovery words are standard BIP39, 12 to 24 words, so you're not locked in. Frost uses the same encryption as every edition, and you can upgrade the license later for emergency or inheritance protocols while keeping the same wallets. Frost is $99 as software for Windows and macOS, with Linux coming soon.
