Frostsnap: Self Custody Designed for Million Dollar Bitcoin
summary
Proposes a concrete multisig redesign using FROST Taproot threshold signatures implemented in daisy‑chained hardware devices that form a 2‑of‑3 by default and ship as a founders edition pack of three. Claims no extra on‑chain fee penalty or privacy leakage versus single‑sig, supports creating new keys from two shares to add custodians, and enables softwar‑enforced spending policies (example: million sats per day) plus per‑device backups using bech32m.
