If the product cannot survive being a boring website, it does not deserve a key.
Web-based is a distribution choice

If they need you to disable antivirus to “trade smarter,” they are not smarter.

Who this setup is for
Web-based used to be an insult from people who sold terminals. Those people also loved local .exes that requested god mode. OpenFidex is web-based because the product is an interface to networks that already live on the internet, and because updates should not arrive as an email attachment.
The cost of that choice is the phishing neighborhood described on the browser page. The benefit is that you can view source in spirit: you know the origin, you can leave, and we cannot pretend a local service is “necessary for latency” when it is actually necessary for key theft.
A short onboarding, then you stay in control
Let the origin update
Web software ships continuously. That is good if you trust the origin and fatal if you do not.
Do not download helpers
Anyone offering a “faster signer plugin” is selling a detour around your common sense.
Interface details that matter for this audience
Same product as “browser,” different noun
Browser is the client. Web-based is the architecture pitch to people comparing desktop suites.
Works on machines you do not admin
A library PC is still a bad place to sign. A locked-down work laptop might be the only computer you have — know the risk.
No updater daemon
The site you loaded is the version you got. That is easier to reason about at 2 a.m.
These guides are web-based too
They are static HTML so they can be read without executing a large application bundle.
Questions this page actually answers
Is web-based slower than native?
For this product’s job, the venue and the human are the bottleneck, not the DOM.
Can I use it in a WebView?
Only if you trust the app that wrapped us. Prefer a real browser.
Do you cache aggressively?
The PWA has a service worker. Marketing pages under /pages/ are denylisted so they do not get replaced by the app shell.
Why static HTML for guides then?
So “web-based” also means readable by things that do not run JavaScript. That is this project’s whole point.
Does OpenFidex hold my funds or place trades for me?
No. OpenFidex is a non-custodial software interface. A wallet is created in your browser, you keep the keys, and you cryptographically sign every order before it reaches a third-party venue such as Hyperliquid. The software does not take custody of assets and does not submit transactions unless you sign them.
