Greenhouse — Self-custody, with grown-ups.

Greenhouse is built on the assumption that your money is your money. It generates and stores key shards across signer devices using FROST threshold signatures — no single party, including Garden, can move funds. Spending policies are enforced before signing: amount limits, address allowlists, time windows, and approval quorums. Greenhouse settles across chains, bridges through reputable routes only, and books every movement into Bean as a journal entry with full provenance. Recovery is a guardian ceremony, not an email reset.
