Transparent Bitcoin Custody

We empower the way you store your bitcoins

CheckSig Custody Solution

CheckSig provides transparent Bitcoin custody solutions for institutional investors and high-net-worth individuals. Ensuring security, regulatory compliance, smooth inheritance, and privacy, we enjoy industry’s leading insurance policy. If requested, we can customize our custody services according to client's requirements: long term safe storage, inheritance plan, or arbitrage trading.


CheckSig rejects the “security-by-obscurity” paradigm in favor of a transparent process. Based on a peer-reviewed open standard protocol, our segregated custody provides periodic proof-of-reserve and is audited by external firms.

Two-level solution

Internet disconnected as defense from remote hacks, our main custody solution has two levels. The cold storage is directly managed by CheckSig and it is always empty except during withdrawals; the “frozen” storage with all assets is managed by multiple external legal entities whose only ability is to jointly move funds to cold storage when technically enabled by us. Both levels are multi-signatures and operated from different geographic locations.

Why Bitcoin

Bitcoin is the best performing asset of the last decade, with almost no correlation with the other asset classes. When added to a diversified asset allocation, Bitcoin reduces overall financial risks for a given expected return or, alternatively, increases expected return for a given level of risk. Digital and scriptural, Bitcoin only exists as validated transaction. It can be transferred but not duplicated (i.e. it can be spent, but not double-spent): it is scarce in the digital realm, as nothing else before. It mimics the gold monetary policy of decreasing incremental extraction: Bitcoin is the digital equivalent of gold with a secure uncensorable embedded settlement network. Bitcoin is a bearer instrument: if you lose your Bitcoin keys you lose your Bitcoin. We are here to help you store your Bitcoins safely.
