Signing messages from runners

[nikolasschoppmeier]

Background

There are a couple of usecases we need to solve for message signing from the runners perspective:

• Messages broadcasted to other chains (in this case Terra), need to be signed. We need a way to sign a CosmWasmExecute message from the runner’s perspective.
• We also need to sign messages in the CosmWasmExecuteMsg format that we are signing to get 2/3 of signatures back.
• And also, we need to sign the message to update the validator set to get a network concensus.

Done when

• We can sign any arbitrary sdk.Msg and also verify signatures
• We allow user to load keyring path in which they have their terra keys stored which is going to be used for message signing.

Done as seen by this test:
https://github.com/VolumeFi/cronchain/blob/ca5cdc0f04592d96735ac979f21d9797de4b6c94/runner/client/sign_test.go#L66-L68

We allow user to load keyring path in which they have their terra keys stored which is going to be used for message signing.
I had to create this Init in our repo instead in the lens repo because lens repo is hardcoding to something that does not work with existing keyrings.

Config is set here
https://github.com/VolumeFi/cronchain/blob/ca5cdc0f04592d96735ac979f21d9797de4b6c94/runner/client/client.go#L18

and a ticket to create actual configs is here #48
