Encointer should not use the same address type as kusama It should be first registered here https://github.com/paritytech/ss58-registry/blob/main/ss58-registry.json and get its own number.
Integritee is ok

[brenzi]

@ainhoa-a I think you misunderstand. Encointer is a systemchain and its native token is the KSM, therefore, like all other system chains, it should use the same ss58 prefix.

However, I just realized Encointer is included in a pending PR #130
therefore, I'll remove Encointer from this PR

[ainhoa-a]

Hi @brenzi ok understood on the prefix, but why are you using a different cla than the generic app? are you planning to have a dedicated app?
If you're planing on using the generic you should use CLA 0xF9

[brenzi]

@ainhoa-a I'm confused. As this PR is only about integritee now, I guess you're talking about that.

The README in this repo says

Take the last used CLA and pick the following number

that's what I did and it seems to be what everyone else did.

Hey @brenzi! Thanks for the contribution. Just to double check, this chain (Integritee) is not levering the new feature on polkadot for generic, right? Ainhoa was asking about the CLA, because in case you are going to use the new app (generic one), there is no need to define the app on this file. You can just use the GenericApp class. In case you are using the legacy app, then it is ok to take the latest value and increase it by 1.

[brenzi]

The generic app is fine for us, thanks for the info. Would be nice if you could make this really obvious in the docs and the readme in this repo

@brenzi I am checking this, as it might be still necessary to add it as PJS needs it.
