Functions

func MigrateKeysv1Tov2 

func MigrateKeysv1Tov2(ctx sdk.Context, providerKeeper Keeper)

Due to https://github.com/cosmos/interchain-security/pull/786, validators' slash logs are stored under the key prefix for slash acks. This method will extract "slash logs" from the slash acks part of the store, and put the slash logs in their appropriate store location.

func MigrateParamsv1Tov2(ctx sdk.Context, paramsSubspace paramtypes.Subspace, consumerRewardDenomRegistrationFee sdk.Coin)

MigrateParamsv1Tov2 migrates the provider CCV module params from v1.0.0 to v2.0.0, setting default values for new params.

func NewMsgServerImpl

NewMsgServerImpl returns an implementation of the bank MsgServer interface for the provided Keeper.

func SlashLogKeyOnlyForTesting 

func SlashLogKeyOnlyForTesting(providerAddr sdk.ConsAddress) []byte
