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

I also found a issue when messages are very long (length > 4k), the notification is not displayed. https://github.com/chainapsis/keplr-wallet/blob/a3aedc2b2769227cbc7e5da0e649101ad3edd721/packages/background/src/tx/service.ts#L181

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.

[giansalex]

Hi @Thunnini, do you have any comments on the direction to take?, the REST server is supported externally as GNO only supports RPC atm.

or Keplr intends to migrate REST queries to RPC queries?
