CUSTODY & TREASURY

Custody you can verify, not just trust

Built on Bitcoin and open standards

The assurances that matter

01
No rehypothecation
Your assets are never lent, reused, or pooled — and you can prove it.
02
Proof of reserves
Verify holdings on-chain, any time, without taking anyone’s word for it.
03
Multisig + HSM
Keys secured across hardware security modules and multiple signers.
04
Segregated accounts
Every client’s assets held separately — never commingled.
