Custody · Greenhouse

Your money, your keys, your terms.

Greenhouse is the crypto layer of Garden. We do not custody your assets — you do, with us as one of n threshold signers. Every spending decision is policy-checked before it is signed. Every signature is reconciled into Bean. There is no email reset. There is a guardian ceremony.

Settles into the book

On-chain doesn't mean off-ledger.

A USDC transfer signed by Greenhouse on Base lands as a balanced journal entry in Bean — sales tax, FX revaluation, and counterparty mapping all derived from the same transaction. Period close includes your on-chain activity by construction; you don’t reconcile it back in.

Vs. the custodians

Self-custody that survives a custodian going dark.

Coinbase Custody and Fireblocks lock you into their key topology. Anchorage holds your keys in a qualified custodian wrapper. Greenhouse is a key topology you own — FROST threshold signing across your own devices, with Garden as one possible signer, never enough to move funds alone.

Recovery

Lose a signer. Don't lose the org.

If a signer device is lost or compromised, recovery is a formal ceremony. A quorum of guardians proves identity, attests to the loss, and rotates the missing share. Time-bounded, signed at every step, recorded in Bean’s audit chain. There is no help desk that can move your money.
