Who we are. What we do.
QNTMEX LTD is a UK-registered company and Quantum EX S.R.O is our CZ-registered partner. Together we provide Web3 infrastructure, self-custody wallet technology, on-chain IP services, and management consultancy — delivering end-to-end solutions for businesses operating in the digital asset and decentralised technology space.
Two registered entities, one group.
QNTMEX operates through two registered companies across the UK and Czech Republic.
QNTMEX LTD
Our UK-registered parent company, responsible for the QNTMEX brand, wallet technology, Web3 & IP services, and overall group operations.
Quantum EX S.R.O
Our CZ-registered partner company — responsible for wallet infrastructure delivery and operations across European markets, and powering the upcoming QNTMEX crypto exchange.
Built on trust. Executed with precision.
Non-Custodial by Design
We never hold, pool, or access user funds. Private keys are on the user's device, always.
Privacy Respecting
No personal data collected to use our wallet. Privacy is a design principle, not a feature.
On-Chain Transparency
Clear terms and verifiable on-chain records. No ambiguity in what we offer.
Broad Consultancy Reach
Our management consultancy advises businesses across technology, operations, and strategy — whatever the sector.
