How to createValidator using authz module?

[Mrigesh901]

I wanted to use authz module in coreum chain, My use case is i want to authorize grantee to run createValidator command and also use grantee's tokens. I have already created the tx of granter,grantee pair using cored tx authz grant command. But i don't know what to do after that such that createValidator command can be run by grantee's account. Please help me with this.

Hey, you need to generate unsigned txn (using --generate-only flag) from granter and broadcast (using exec command) it from grantee.

Hey, thank you. In the next step, after the unsigned transaction is created and saved as tx.json, how do we send it to grantee side. Is there a method by which grantee can broadcast the transaction from any UI wallet like keplr or metamask . For example, grantee does not want to run cli, and has a browser wallet, how does he get tx.json to his wallet from the backend and he just have to approve it.

Hey, you don't need to send txn to grantee, the grantee can create the unsigned txn with the address of granter directly
for example:

simd tx bank send granterAddr cosmos1... 10stake --generate-only > tx.json

https://resolute.vitwit.com is having UI for some authz operations, but I guess createValidator is not included (may be upcoming)
