This abstracts part of a user's interaction with an account she controls. It's not an abstraction of core Ethereum accounts data type / logic - for that see the core processing code of blocks / txs.

Currently this is pretty much a passthrough to the KeyStore2 interface, and accounts persistence is derived from stored keys' addresses

Types

type Account

type Account struct {
	Address common.Address
}

type Manager

type Manager struct {
	// contains filtered or unexported fields
}

func NewManager

func NewManager(keyStore crypto.KeyStore2) *Manager

func (*Manager) Accounts

func (am *Manager) Accounts() ([]Account, error)

func (*Manager) DeleteAccount

func (am *Manager) DeleteAccount(address common.Address, auth string) error

func (*Manager) Export

func (am *Manager) Export(path string, addr common.Address, keyAuth string) error

USE WITH CAUTION = this will save an unencrypted private key on disk no cli or js interface

func (*Manager) HasAccount

func (am *Manager) HasAccount(addr common.Address) bool

func (*Manager) Import

func (am *Manager) Import(path string, keyAuth string) (Account, error)

func (*Manager) ImportPreSaleKey

func (am *Manager) ImportPreSaleKey(keyJSON []byte, password string) (acc Account, err error)

func (*Manager) NewAccount

func (am *Manager) NewAccount(auth string) (Account, error)

func (*Manager) Primary

func (am *Manager) Primary() (addr common.Address, err error)

func (*Manager) Sign

func (am *Manager) Sign(a Account, toSign []byte) (signature []byte, err error)

func (*Manager) TimedUnlock

func (am *Manager) TimedUnlock(addr common.Address, keyAuth string, timeout time.Duration) error

TimedUnlock unlocks the account with the given address. When timeout has passed, the account will be locked again.

func (*Manager) Unlock

func (am *Manager) Unlock(addr common.Address, keyAuth string) error

Unlock unlocks the account with the given address. The account stays unlocked until the program exits or until a TimedUnlock timeout (started after the call to Unlock) expires.
