	AccountNumber int64
	Sequence      int64

nolint

func (StdTx) GetSignatures added in v0.18.0 

func (tx StdTx) GetSignatures() []StdSignature

Signatures returns the signature of signers who signed the Msg. GetSignatures returns the signature of signers who signed the Msg. CONTRACT: Length returned is same as length of pubkeys returned from MsgKeySigners, and the order matches. CONTRACT: If the signature is missing (ie the Msg is invalid), then the corresponding signature is .Empty().

func (StdTx) GetSigners added in v0.20.0
