QNTMEX is a technology group. We build self-custody wallet software, Web3 and blockchain engineering, on-chain IP services, and technical consultancy. We do not hold, control or administer customer funds or crypto-assets, and we provide no exchange, custody or other regulated financial service.
QNTMEX operates through two registered technology companies. Neither holds customer funds or crypto-assets, and neither provides regulated financial or crypto-asset services.
UK-registered technology company. Owns the QNTMEX brand and develops and maintains the non-custodial wallet software, Web3 and blockchain engineering, and technical consultancy. It holds no financial licence and provides no custody, exchange or other regulated financial service.
Czech-registered software and blockchain development company. Its activity is software development and technical work only. It is not authorised as a crypto-asset service provider and provides no custody, exchange or other regulated crypto-asset service.
We never hold, pool, or access user funds. Private keys are on the user's device, always.
No personal data collected to use our wallet. Privacy is a design principle, not a feature.
Clear licensing terms, public IP registers, and on-chain ownership records. No ambiguity in what we offer.
Our management consultancy is not limited to the digital asset space. We advise businesses across technology, operations, and strategy — whatever the sector.
