Types

type Account added in v0.18.0 

type Account interface {
	GetAddress() sdk.AccAddress
	SetAddress(sdk.AccAddress) error // errors if already set.

	GetPubKey() crypto.PubKey // can return nil.
	SetPubKey(crypto.PubKey) error

}

StdTx is a standard way to wrap a Msg with Fee and Signatures. NOTE: the first signature is the fee payer (Signatures must not be nil).

func (tx StdTx) GetSigners() []sdk.AccAddress

GetSigners returns the addresses that must sign the transaction. Addresses are returned in a deterministic order. They are accumulated from the GetSigners method for each Msg in the order they appear in tx.GetMsgs(). Duplicate addresses will be omitted.
