Who we are
Chainzano connects products that can work independently or together in one infrastructure stack.
Chainzano s.r.o. operates from Bratislava, Slovakia and focuses on resilient digital systems where data ownership, compute access, privacy and user-controlled identity matter.
Portfolio approach
We build and operate four connected products: ExtraChain, Argentum AI, RaccoonLine and NexPort.
Real infrastructure domains
The portfolio covers decentralized data, enterprise AI compute, privacy networking and digital identity.

REASON TO CHOOSE US
What ties the portfolio together.
ExtraChain
Data layer
ExC, ExDFS and Historical Chain support decentralized storage, shared state and data integrity workflows.
Argentum AI
Compute layer
Enterprise AI compute can be sourced through one access layer across globally contracted capacity.
RaccoonLine
Privacy layer
The privacy stack combines dVPN, storage and messaging for users who want more control at the network edge.
NexPort
Identity layer
NexPort bridges Web2 and Web3 data, access keys and zero-proof 2FA.
Shared storage
workflows
ExDFS is designed for encrypted, distributed file access across applications and services.
Web2 and Web3
integration
The portfolio is built to connect modern decentralized systems with practical business workflows.
Partner delivery
model
Products can be adopted individually or delivered as a broader multi-system infrastructure program.
Regulated environment readiness
The architecture is positioned for organizations that care about control, privacy and operational resilience.
How the portfolio is organized
- Independent products with shared infrastructure logic
- Practical delivery for real workloads rather than template-only positioning
- Privacy, access control and interoperability as first-class concerns

Portfolio highlights
Four products, three infrastructure themes
ExtraChain provides blockchain infrastructure, ExDFS storage and Historical Chain data integrity for applications that need distributed persistence.
ExtraChain / data infrastructure
Argentum AI gives enterprise teams access to orchestrated GPU capacity through one institutional cloud interface rather than fragmented sourcing.
Argentum AI / enterprise compute
RaccoonLine and NexPort extend the portfolio into privacy networking, secure messaging and user-controlled identity.
