…2290) * change DefaultParams on the host to allow all messages ("*") Interchain Accounts are used by controller chains to execute transactions on the host chain. My suggestion is just as normal wallets are allowed to submit any transaction, by default, the host should allow all types of messages to be submitted using the ICAs. Allowing all messages by default makes more sense regarding the purpose of Interchain Accounts. Otherwise, it looks like this parameter should be configured to enable Interchain Accounts. * correct formatting (gofumpt) correct formatting (gofumpt) * hold wildcard string in a constant * add changelog Co-authored-by: george <> Co-authored-by: Carlos Rodriguez <[email protected]> Co-authored-by: colin axnér <[email protected]>
