Given the strong presence of our hyper-active Council and Community in these public (i.e. not in a walled-off apps closed to the world) venues where potential users builders and (gasp!) buyers might see it, one can’t help but feel “The future is so bright I have to wear shades”!

Now I just miss one key piece of info before I start brainstorming what to build: what known-to-work, frustration-free examples of getting started with cMixx services exist today?

Background: last time I tried ( [Do xxDK (and validator rules) need an update?](https://forum.xx.network/t/do-xxdk-and-validator-rules-need-an-update/7264) ) I ended up wasting hours of my time without getting anything in return. Some “workarounds” were mentioned, but not elaborated on.

### Did some fixes for htmljs example here

> **[haven-app-ios/htmljs at example-fix · thisisommore/haven-app-ios](https://github.com/thisisommore/haven-app-ios/tree/example-fix/htmljs)**

It will now show network status  
and uses local wasm\_exec.js since [https://elixxir-bins.s3-us-west-1.amazonaws.com/wasm/xxdk-wasm-0.3.19/dist/wasm\_exec.js](https://elixxir-bins.s3-us-west-1.amazonaws.com/wasm/xxdk-wasm-0.3.19/dist/wasm_exec.js) gives CORS error.

Updated commands (for fetching wasm\_exec.js locally before dev server)

```bash
mkdir -p dist
curl -o dist/wasm_exec.js \
  https://elixxir-bins.s3-us-west-1.amazonaws.com/wasm/xxdk-wasm-0.3.19/dist/wasm_exec.js
python3 -m http.server

```

It takes some time for network to be ready, I suppose due local ndf file not updated and therefore it takes time to prepare working set of network.

Continuing from [xxB-2024-003: Haven Browser Extension Implementation - #16 by m.f](https://forum.xx.network/t/xxb-2024-003-haven-browser-extension-implementation/7056/16) since it’s more appropriate to ask in this topic: I’ve never understood (since the first xxDK) why demos cannot load a Haven identity file and join a channel.

How is this Related to the browser extension? Well, I haven’t used it but I’ve seen a video demo and was thinking it might be possible to:

a) Have an ID store (could be independent from Haven cache)

b) Then, if an API is exposed, one could auth to the extension which would handle “load & login”. Maybe there’s a version of that already, but in the video a new Haven identity was created so I don’t know.

c) Similarly to Web wallets, one could even store a dict of identities and channels, to have everything in one place. Then, finally, apps like this simpler chat app (not necessarily Haven) could use the extension as a kind of Web wallet, where Haven identity is like wallet address, and channels are like fungible assets… In cases like this, convenience is required, so the ability to load 1 identity and 1 channel would be sufficient. Load, message, unload.

With this approach it would be possible to use cMixx for comms and notification from apps (automation) which is a big pain point with Haven.
