Functions

func BurnFeeHandler added in v0.18.0 

func BurnFeeHandler(_ sdk.Context, _ sdk.Tx, _ sdk.Coins)

BurnFeeHandler burns all fees (decreasing total supply)

func FeePayer added in v0.18.0

func NewHandler(am AccountMapper) sdk.Handler

NewHandler returns a handler for "baseaccount" type messages.

func RegisterBaseAccount added in v0.18.0 

func RegisterBaseAccount(cdc *wire.Codec)

func StdSignBytes added in v0.18.0 

func StdSignBytes(chainID string, sequences []int64, fee StdFee, msg sdk.Msg) []byte

func WithSigners 

func WithSigners(ctx types.Context, accounts []Account) types.Context

func (msg StdSignMsg) Bytes() []byte

get message bytes

type StdSignature added in v0.18.0
