Casa has presented 1 V-Sum technical briefing. Casa demos its personal key-manager product for Bitcoin self-custody — a safe, visually-consumer-first way to hold Bitcoin private keys without falling off the "one key, one pool of coins" cliff that has already lost an estimated 4M of Bitcoin\'s 21M total supply. At Casa\'s highest security tier, five keys protect one Bitcoin pool (mobile phone, three hardware wallets, one emergency Casa-held key) under a 3-of-5 multi-sig — losing any one key doesn\'t risk your funds. A separate "checking account" uses a single mobile key for fast spending. The send flow shows the multi-sig in action: the phone signs first, Casa emails a prompt to plug in a Trezor or Ledger for the second signature, and a third hardware approval broadcasts the transaction to Bitcoin\'s network. QR-code-based signing on next-gen hardware wallets will eliminate the email step. Casa\'s replace-a-lost-key flow skips seed-phrase recovery entirely — mark the key compromised, add a new hardware device, and transfer funds with the remaining healthy keys. Premium service tiers offer concierge-style support for high-net-worth holders.
