Free & unlimited for 7 days
ProofChain
Timestamping
Provides verifiable evidence of file possession with secure, tamper-proof timestamps on upload.
End-to-End Encryption
Client-side encryption ensures only authorized parties can decrypt and access your data.
Subscriber-Owned Uploads
Your files, your rules. You stay in complete control at all times. Only people you authorise have access.
Local Data Residency
Keep your data where it matters, with region-specific storage to support regulatory compliance.
Multiple projects on the go?
This is your vault.
When you’re juggling multiple projects, ideas, or records, basic cloud storage falls short. It
lacks the defensible proof and control you need when value or disputes are involved.
arxMulti gives you a single, powerful vault where you can build a separate ProgressChain for each asset, combined with the independent ProofChain timestamp received by each file on upload.
Upload, update, and track the evolution of many files from a single location without losing the chronological, tamper-proof history that makes your work legally defensible.
Ideal for:
-
Multiple inventions, business concepts or R&D projects
-
Trades records, job progress photos, safety checklists and handovers
-
Creative portfolios, manuscripts, designs and storyboards
-
Business documents — pitch decks, financial models, HR policies, meeting minutes
-
Legal and compliance files across different matters
-
Personal projects combined with professional work
Start in arxMulti and seamlessly upgrade any individual asset to a dedicated arxCommercial vault if and when
you’re ready to monetise it through arxMarket — no re-uploading required.
Built for ease of use
Simple, mobile-friendly design
Manage your vault from your browser or from your phone or tablet in seconds with the ARX mobile app - perfect for tradespeople and inventors capturing on-site photos, notes, or updates in real time.

ProgressChain
With ProgressChain, every file is hash-linked to the one before it to provide immutable version history, with each also carrying its own cryptographic ProofChain timestamp.

Your files stay truly private with end-to-end military grade encryption from the moment of upload.
Receive instant notifications for unauthorised file access attempts.
