The Vault: MPC custody built for Abra Capital Management.
Abra Financial Holdings developed the Vault, the custody technology Abra Capital Management uses for its clients. In an ACM managed account, your assets are held in your name by Fireblocks Trust Company, LLC, an independent limited-purpose trust company chartered by the New York State Department of Financial Services. Fireblocks secures the account with multi-party computation (MPC) key technology. Abra Capital Management (ACM) is your investment adviser.
One vault per client, never a pooled wallet.
The Vault gives every Abra Capital Management client a segregated account of their own, titled to that client and kept apart from Abra's assets and from other clients.
Assets are held in MPC wallets, so no single key, device or person can move them, and every transaction leaves a record ready for audit.

How the Vault keeps assets secure
Keys that never exist in one place
With multi-party computation, a signing key is created and used as separate shares held by different parties. The full key is never assembled, so there is no single point of compromise.
Policy-controlled signing
A transaction is signed only when its approval policy is met: the right approvers, within set limits, to allow-listed addresses.
Reconciled and recorded
Onchain balances are compared with account records continuously. Exceptions are flagged for review, and every movement is logged for audit.

Understand the Risk
Abra Financial Holdings develops technology. It does not itself provide investment advice or custody. Custodial services are offered to clients of Abra Capital Management LP, an SEC-registered investment adviser; registration does not imply a certain level of skill or training. Custody is protected with multi-party computation (MPC) key storage, in segregated accounts titled to the client at Fireblocks Trust Company, LLC. Digital assets are not deposits and are not FDIC insured.
