Transparent Bitcoin Custody

CheckSig provides transparent bitcoin custody for institutions and high-net-worth individuals. Our solution is based on a public open standard protocol: we reject security by obscurity in favor of an extremely auditable process.
Our multi-level multi-party multi-location custody solution provides periodic proof-of-reserve blockchain transactions, is hardened by customized multi-signature hardware, and is covered by insurance guarantees.

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