func AppStateFn 

func AppStateFn(cdc codec.JSONCodec, simManager *module.SimulationManager, genesisState map[string]json.RawMessage) simtypes.AppStateFn

AppStateFn returns the initial application state using a genesis or the simulation parameters. It calls AppStateFnWithExtendedCb with nil rawStateCb.

func DiffKVStores added in v0.50.0 

func DiffKVStores(a, b storetypes.KVStore, prefixesToSkip [][]byte) (diffA, diffB []kv.Pair)

DiffKVStores compares two KVstores and returns all the key/value pairs that differ from one another. It also skips value comparison for a set of provided prefixes.

func GenSignedMockTx 

func GenSignedMockTx(r *rand.Rand, txConfig client.TxConfig, msgs []sdk.Msg, feeAmt sdk.Coins, gas uint64, chainID string, accNums, accSeqs []uint64, priv ...cryptotypes.PrivKey) (sdk.Tx, error)
