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

	GetAccountNumber() uint64
	SetAccountNumber(uint64) error

	GetSequence() uint64
	SetSequence(uint64) error

	GetCoins() sdk.Coins
