Massively scalable to meet your requirements and the ever-growing demand for digital asset storage. Our stateless bunker technology enables limitless scalability and the core product has no storage constraints meaning we can support any number of vaults

Automated

All cold protected cryptographic processes are automated requiring zero human involvement thus removing the risks of malicious actors or human errors

Accessible

Our versatile authorisation scheme enables customers to implement approval processes in line with their existing security standards and policies

Insurable

Insurable assets - Our vaults have been designed to meet the stringent risk requirements of the world's largest insurance syndicates

Compliance and Controls

Custodiex is ISO 27001 certified. Our product aligns to current regulation and exceeds the security standards used by traditional payment schemes whilst being continuously verified against CCSS guidelines

Borderless

Our cold protected vaults can store your digital assets in many geographical locations to meet your regulatory and jurisdictional requirements

Ease of Use

Through our standards-based API and our flexible authorisation scheme, we provide simple integration with your existing technologies, cryptographic systems and processes

Cryptographically Agile

We separate transaction authorisation keys from asset keys providing security and agnosticity not possible with MPC solutions. We also enable support for any current or future cryptography, including post quantum algorithms

Key Management

Our robust key management processes combined with our layered role-based access controls offer the highest level of secure digital asset management exceeding current and future industry standards

Agnostic

Our vault is Asset & Ledger Agnostic; currently capable of storing Bitcoin, Ethereum, ERC-20, ERC-721 & ERC-1155 tokens, and designed to store any other blockchain (public or private) asset, on any network you require in the future

Frequently Asked Questions

Does the solution use MPC?

Custodiex ruled out the use of MPC from the start because we wanted to build a solution with specific qualities that MPC cannot provide. Our solution uses FIPS certified hardware and NIST approved algorithms in-line with banking standards, has a highly flexible authorisation scheme, is long-term asset agnostic and crypto agile, and is cold-grade yet fully automated and limitlessly scalable. And crucially, our solution provides full custody, without requiring the customer to safeguard shards of the asset.

Does the Blockchain Vault solution use HD Wallets?

HD Wallets are a great solution for individuals choosing to self-custody, enabling all the keys within a wallet to be recreated from a single seed phrase should the wallet become lost. However, HD Wallets only support specific asset types, and the standards relating to these wallets are constantly evolving. There is also the concern that every single key in the wallet is compromised if a single seed phase becomes known to another party. These concerns around stability, crypto agility and security make the use of HD Wallets within an enterprise-grade crypto custody solution questionable. The Custodiex solution provides guaranteed durability and micro-segmented security for keys under custody, whilst avoiding all the concerns present with HD Wallets.

What is an Airgap and how does yours work?

An network airgap isolates a computer (or network) from another (less secure) network, creating an "offline" or "cold" environment. Traditionally airgaps use manual processes which introduce delays, human errors, and operational headaches. The Custodiex airgap is automated and operates in real time, isolating the cryptographic processing environment from the network for maximum security, and enabling cold protection for digital assets with the speed of hot.
CREST accredited penetration testers have independently verified that our airgap removes all network-based attack vectors and our airgap design means that airgap throughput does not limit our ability to process massive transaction volumes. For a deeper dive into our technology (under NDA) please get in touch.

How do you protect Blockchain Private Keys?

Blockchain private keys are generated in our cold environment, inside FIPS assured HSMs. All cryptographic operations are handled by our cold protected HSMs, including the signing of blockchain transactions. These HSMs have not been modified in any way, and are not using custom firmware providing maximum assurance for the protection of your assets. Despite this, we do not suffer from the storage, backup, cost, or scalability constraints commonly seem in HSM based custody solutions. Our solution isn't just hardware and software, people and process is just as important; we can demonstrate mature, robust operating procedures, including detailed key and HSM management processes where chain of custody for cryptographic components is appropriated managed. We can explain more in a deep dive of our solution.

How do I authoriser transactions through the API?

Custodiex customers use cryptographic keys of any type, which are not cryptographically linked to the blockchain private key, and which can be replaced if lost, to sign transaction intents in an 'm of n' policy. The Custodiex policy structure does not impose any limitation on the 'm of n' implementations employed by our customers. For transactions authorisation customers can use simple 1 of 1 policies, more standard 2 of 3 policies, more extreme 15 of 25 policies, or anything else they can think of (including requiring multiple 'm of n' authorisations for a single transaction).

How do I get an API key and a copy of your API documentation?
