`@cosmjs/launchpad` is unmaintained and deprecated

[pyramation]

@cosmjs/launchpad is unmaintained and deprecated, we should upgrade cosmjs.

many types from @cosmjs/launchpad are in @cosmjs/amino or @cosmjs/proto-signing now.

Ideally would be great to upgrade to 0.29.

Overall I agree with this issue. However, keplr lacks motivation to update cosmjs for the following reasons.

• Most of the parts used in keplr are typing or core logic that makes sign doc. This logic is not updated often.
• The typing of cosmjs is not actively updated and does not reflect the latest cosmos-sdk's feature. (Keplr does not support all the latest features either.)

But this issue is right. We will update it soon.

Thanks @Thunnini !!

If you're interested in some details aside from the unmaintained and deprecated parts:

Actually the main motivation is that due to changes in recent additions of cosmjs, if you use the wallet-connect for keplr mobile (as in cosmos-kit) — keplr-wallet wallet-connect will pull in an old version of cosmjs, and therefore provide mismatched types.

Effectively when you begin to create custom signers with amino encoding registries, and proto encoding registries, if you use cosmos-kit (or keplr-wallet wallet-connect), you end up getting strange errors as a result of bad npm resolutions.

Upgrading cosmjs to a more recent version fixes this. 0.29 would be amazing, it's well tested at this point.

Please ping me or @webmaster128 if you have any questions about types and where they live now if you need any help.

@pyramation @keupsonite Hey, I removed @cosmjs/* from dependencies. I expect that it can solve your problems. And, it is published with version 0.11.16-alpha.0 Can you check that the problems are fixed with 0.11.16-alpha.0?

[pyramation]

So far looking good!

I did notice one dep in the yarn.lock, all of the required cosmjs packages were up to date, except for one:

here is a comment so you can see where

"@cosmjs/crypto@^0.24.0-alpha.25", "@cosmjs/crypto@^0.29.3"

Probably because of this resolution here

Maybe it's not a big deal though! I think removing launchpad was the most important part.

@cosmjs/stargate exists for compatibility testing with cosmjs. However, packages uploaded to npm do not have @cosmjs/* as a dependency. However, it seems that secretjs has a part of @cosmjs as a dependency. We will also remove secretjs itself later. But now, I have a part of @cosmjs/* indirectly by secretjs, so I don't know if this will be a problem or not.

ok great, sounds good!

[pyramation]

@Thunnini thanks a lot for doing this PR! I'm super grateful and appreciative!

So far removing launchpad and cosmjs/* has cleaned up many deps! This is great!

We're already using 0.11.16-alpha.0 in production for chain-registry and also cosmos-kit

[Thunnini]

0.11.16 is published to npm. You can use +0.11.16 version.
