From Unacceptable Risk to Institutional Standard
Managing digital assets is no longer a niche experiment; it's a core requirement for modern finance. But the risks are immense. A single private key compromised, a flawed transaction policy, or a regulatory misstep can lead to catastrophic losses and reputational ruin. Standard security measures are not enough. You need a custody framework built from the ground up for the unique challenges of blockchain assets. We provide that framework, transforming the inherent risks of digital assets into a secure, compliant, and scalable operational advantage for your institution.

Frequently Asked Questions
Clear answers to your most pressing questions about our institutional crypto custody solutions.
MPC is an advanced cryptographic technique where a private key is split into multiple encrypted "shares." These shares are distributed and used to sign transactions without ever combining them. This eliminates the single point of failure of a complete private key. Unlike traditional multi-sig, which is blockchain-specific and can have higher transaction fees, MPC is blockchain-agnostic, more flexible for setting complex policies, and offers a higher level of security as the full key is never exposed.
Our cold storage solutions use a defense-in-depth approach. Private keys are generated and stored in air-gapped, FIPS 140-2 Level 3+ certified Hardware Security Modules (HSMs) located in geographically distributed, access-controlled vaults. All operations require the physical presence of multiple authorized personnel in a strict, auditable ceremony. This combination of physical, procedural, and cryptographic security provides the highest level of protection against online threats.
We offer flexible deployment models to meet your specific security and regulatory requirements. Our standard offering is a highly secure, managed cloud deployment (SaaS) on AWS or Google Cloud, which allows for rapid setup and scalability. For institutions with specific data residency or control requirements, we also offer a hybrid model or a fully on-premise deployment where the software runs within your own data centers.
Our platform is blockchain-agnostic and built for broad asset support. We have native support for all major blockchains like Bitcoin, Ethereum (and all ERC-20, ERC-721, etc., tokens), Solana, Polygon, and many others. Our modular architecture allows us to rapidly add support for new blockchains and token standards based on client needs. We can securely custody fungible tokens, NFTs, security tokens, and other complex digital assets.
Our platform includes an integrated compliance module designed to address key regulations. For the FATF Travel Rule, we integrate with leading industry solutions and protocols (like TRP or TRISA) to automate the detection of transactions that require data sharing and facilitate the secure exchange of originator and beneficiary information with other Virtual Asset Service Providers (VASPs). This helps you meet your obligations efficiently and with a full audit trail.
The timeline depends on the complexity and deployment model. For our white-label SaaS solution with standard configurations, clients can be operational in as little as 2-3 months. A more customized solution or an on-premise deployment typically takes 4-6 months. Our process includes a dedicated project manager and solutions architect to ensure a smooth and efficient implementation from kickoff to go-live.
