Yes!
Here is an example that includes building your own client
But you'll likely appreciate some of the tooling that abstracts away creating clients such as Cosmodal or Graz
Here is a great intro for how to use clients that also includes example usage of Cosmodal
And here is a tool that is very useful for interacting with smart contracts from a frontend
Thank you

Hey @dmiric and @LeTurt333
For new chains, you may need to convert their proto files into the proper encoding. For this, you'll want to use Telescope
However, if you're using osmosis, juno, or stargaze, you can use these create-cosmos-app examples with pre-built libraries that already used Telescope, and also have everything ready to make transactions:
npm install -g create-cosmos-app
uses osmojs
cca --name myosmoapp --example --template osmosis
uses juno-network
cca --name myjunoapp --example --template juno
uses stargazejs
cca --name mystarsapp --example --template stargaze
@pyramation Definitely going to check this out, thanks 🔥
I found the other way to do it. Now I'm only stuck on how to use evmos. My new method doesn't cover evmos for some reason. I haven't found a way to send evmos tokens using nodejs without keplr.

if you need evmos use evmosjs, cosmjs doesn't support EVM: https://github.com/evmos/evmosjs
How can comosjs be used for kava?

Hey @heindrick17
You can use kavajs
https://www.npmjs.com/package/kavajs
If there are issues (I know they still need to update amino message names, but you should be able to use direct signer today) please make them here https://github.com/cosmology-tech/kavajs
Thank you @pyramation
However, when I try to test with kavajs, I am getting Error: Bad status on response: 501
on getSigningKavaClient
function.
I am using my RPC server url. Is my rpc server causing issue?

means you are likely passing in a endpoint that is not RPC, or the RPC node is experiencing issues.

This is full error log. Do you have any idea why? My RPC server is working and I am able to call apis to it.
According to my check library code, it just make POST request to RPC server url. There isn't any implementation in root path(RPC server url itself), my RPC server response 501 Not Implemented error. Do you have any idea? @webmaster128 @pyramation

Honestly, I would ask the Kava team, Kava discord, or somebody in the Kava dev community. Maybe kava is doing some non-cosmos-standard thing with their nodes that I'm unaware of.
I don't think it is related to Kava. I have cosmos RPC server also, it doesn't have any implementation for root path. It will also response 501 error.
Oh, I found issue. I was using REST API type RPC server. After I used tendermint RPC server, issue is gone, I can run code. Thank you. @pyramation
Can cosmjs be used to sign and broadcast transactions to chains like osmosis, kava, juno and others? If yes can someone point me to an example of such a usage?
