Transparent Bitcoin Custody

CheckSig provides transparent bitcoin custody solutions for institutional investors and high-net-worth individuals.
We reject security by obscurity in favor of an extremely auditable process: our main solution is based on a public open standard protocol: multi-level, multi-party, and multi-location, it provides periodic proof-of-reserve blockchain transactions, is hardened by customized multi-signature hardware, and is covered by insurance guarantees.
We customize our custody services according to client's requirements: long term safe storage, inheritance plan, or arbitrage trading, we empower the way you store your bitcoins.

About the protocol


Bitcoin is about financial sovereignty and having direct control of your keys because, as people say, not your keys, not your bitcoins. Nonetheless, there are cases like institutional investors, high-net-worth individuals, lack of proper technical skills, etc. where a custodial solution might be convenient or even prescribed.

CheckSig implements an open transparent multi-party custody protocol that:

  • avoids reliance on "security by obscurity", being an auditable public standard subject to peer review;
  • provides transparency to the custodian's clients, so that they can be certain that their assets are held in a secure manner.

The guiding principles defining this protocol are:

  • to store the bitcoins under custody in such a way as to minimize risk of loss of funds through theft, error, or other mishaps;
  • to rely on the Bitcoin protocol implementation for security wherever possible, rather than inventing new functionality or procedures;
  • to remain neutral regarding future changes to the Bitcoin protocol.
