thanks gian this is really usefull

[giansalex]

I've been testing, and it's working properly, including other chains.
tomorrow will probably be ready for review

Hello @Thunnini, I think this is ready, it will be very useful to have this integration complete for GNO apps.
let me know if you have suggestions

[Thunnini]

@giansalex Are there ways to test GNO on keplr? TBH, I don't follow up the status of GNO chain. Is there a testnet?

[giansalex]

@Thunnini , you can test here https://app.gno.tools/transfer , it supports keplr with the latest GNO testnet.

Faucet: https://test2.gno.land/faucet

[giansalex]

@Thunnini , I resolved merge conflict with master branch, let me know if you have any problems with gnoland testnet.

[Thunnini]

Hey, I haven't forgotten this. Another milestone is being processed. I'm sure to check next week and merge if there are no problems

[giansalex]

I added the balance validation on MsgSend.

[Thunnini]

@giansalex Apologies for the late review on this. One of the biggest problem I’m facing right now is that I do not know anything about Gno. I did check that your code works fine in the testnet. But AFAIK, Jae did not like protobuf and I thought grpc would not be a part of the chain. Also, when I checked on the repo, I wasn’t able to find any traces of grpc. But on your code, it queries via existing grpc gateway endpoint. Are you sure this works well in mainnet as well? Where would I be able to locate this part in the gno repo?

[giansalex]

@Thunnini , for queries like balance and txs broadcast, I have used this repo to match cosmos-sdk endpoints.
mainnet is not closed yet, any new changes will be reviewed before launch.

Hey @Thunnini,

Are you still open to the gno team adding Gno support in Keplr?
We can dedicate some dev time to making sure it's supported properly
