Warning

Do not use in production!
This is a simple POC, no error management is carried out so only use it in dev mode

ignite scaffold chain mychain
ignite s module coin-actions --dep bank
ignite s message MintCoinsAction coins:coins --module coin-actions
ignite s message BurnCoinsAction coins:coins --module coin-actions

edit: x/coinactions/types/expected_keepers.go, add in BankKeeper
