type UniqueID added in v1.0.0 

type UniqueID [crypto.EntropySize]byte

UniqueID is a unique id randomly generated and put at the front of every persistence object. It is used to make sure that a different encryption key can be used for every persistence object.

type Wallet 

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

Wallet is an object that tracks balances, creates keys and addresses, manages building and sending transactions.

func New 

func New(cs modules.ConsensusSet, tpool modules.TransactionPool, persistDir string) (*Wallet, error)

New creates a new wallet, loading any known addresses from the input file name and then using the file to save in the future. Keys and addresses are not loaded into the wallet during the call to 'new', but rather during the call to 'Unlock'.

func (*Wallet) AddressTransactions added in v1.0.0 

func (w *Wallet) AddressTransactions(uh types.UnlockHash) (pts []modules.ProcessedTransaction)

AddressTransactions returns all of the wallet transactions associated with a single unlock hash.

func (*Wallet) AddressUnconfirmedTransactions added in v1.0.0 

func (w *Wallet) AddressUnconfirmedTransactions(uh types.UnlockHash) (pts []modules.ProcessedTransaction)

AddressUnconfirmedHistory returns all of the unconfirmed wallet transactions related to a specific address.

func (*Wallet) AllAddresses added in v1.0.0 

func (w *Wallet) AllAddresses() []types.UnlockHash

AllAddresses returns all addresses that the wallet is able to spend from, including unseeded addresses. Addresses are returned sorted in byte-order.

func (*Wallet) AllSeeds added in v1.0.0 

func (w *Wallet) AllSeeds() ([]modules.Seed, error)

AllSeeds returns a list of all seeds known to and used by the wallet.

func (*Wallet) ConfirmedBalance added in v1.0.0 

func (w *Wallet) ConfirmedBalance() (siacoinBalance types.Currency, siafundBalance types.Currency, siafundClaimBalance types.Currency)

ConfirmedBalance returns the balance of the wallet according to all of the confirmed transactions.

func (*Wallet) CreateBackup added in v1.0.0 

func (w *Wallet) CreateBackup(backupFilepath string) error

CreateBackup creates a backup file at the desired filepath.

func (*Wallet) Encrypt added in v1.0.0 

func (w *Wallet) Encrypt(masterKey crypto.TwofishKey) (modules.Seed, error)

Encrypt will encrypt the wallet using the input key. Upon encryption, a primary seed will be created for the wallet (no seed exists prior to this point). If the key is blank, then the hash of the seed that is generated will be used as the key. The wallet will still be locked after encryption.

Encrypt can only be called once throughout the life of the wallet, and will return an error on subsequent calls (even after restarting the wallet). To reset the wallet, the wallet files must be moved to a different directory or deleted.

func (*Wallet) Encrypted added in v1.0.0 

func (w *Wallet) Encrypted() bool

Encrypted returns whether or not the wallet has been encrypted.

func (*Wallet) Load033xWallet added in v1.0.0 

func (w *Wallet) Load033xWallet(masterKey crypto.TwofishKey, filepath033x string) error

Load033xWallet loads a v0.3.3.x wallet as an unseeded key, such that the funds become spendable to the current wallet.

func (*Wallet) LoadSeed added in v1.0.0 

func (w *Wallet) LoadSeed(masterKey crypto.TwofishKey, seed modules.Seed) error

LoadSeed will track all of the addresses generated by the input seed, reclaiming any funds that were lost due to a deleted file or lost encryption key. An error will be returned if the seed has already been integrated with the wallet.

func (*Wallet) LoadSiagKeys added in v1.0.0 

func (w *Wallet) LoadSiagKeys(masterKey crypto.TwofishKey, keyfiles []string) error

LoadSiagKeys loads a set of siag-generated keys into the wallet.

func (*Wallet) Lock added in v1.0.0 

func (w *Wallet) Lock() error

Lock will erase all keys from memory and prevent the wallet from spending coins until it is unlocked.

func (*Wallet) NextAddress added in v1.0.0 

func (w *Wallet) NextAddress() (types.UnlockConditions, error)

NextAddress returns an unlock hash that is ready to recieve siacoins or siafunds. The address is generated using the primary address seed.

func (*Wallet) PrimarySeed added in v1.0.0 

func (w *Wallet) PrimarySeed() (modules.Seed, uint64, error)

PrimarySeed returns the decrypted primary seed of the wallet.

func (*Wallet) ProcessConsensusChange added in v1.0.0 

func (w *Wallet) ProcessConsensusChange(cc modules.ConsensusChange)

ProcessConsensusChange parses a consensus change to update the set of confirmed outputs known to the wallet.

func (*Wallet) ReceiveUpdatedUnconfirmedTransactions added in v1.0.0 

func (w *Wallet) ReceiveUpdatedUnconfirmedTransactions(txns []types.Transaction, _ modules.ConsensusChange)

ReceiveUpdatedUnconfirmedTransactions updates the wallet's unconfirmed transaction set.

func (*Wallet) RegisterTransaction 

func (w *Wallet) RegisterTransaction(t types.Transaction, parents []types.Transaction) modules.TransactionBuilder

RegisterTransaction takes a transaction and its parents and returns a TransactionBuilder which can be used to expand the transaction. The most typical call is 'RegisterTransaction(types.Transaction{}, nil)', which registers a new transaction without parents.

func (*Wallet) SendSiacoins added in v1.0.0 

func (w *Wallet) SendSiacoins(amount types.Currency, dest types.UnlockHash) ([]types.Transaction, error)

func (*Wallet) SendSiafunds added in v1.0.0 

func (w *Wallet) SendSiafunds(amount types.Currency, dest types.UnlockHash) ([]types.Transaction, error)

SendSiafunds creates a transaction sending 'amount' to 'dest'. The transaction is submitted to the transaction pool and is also returned.

func (*Wallet) StartTransaction added in v1.0.0 

func (w *Wallet) StartTransaction() modules.TransactionBuilder

StartTransaction is a convenience function that calls RegisterTransaction(types.Transaction{}, nil).

func (*Wallet) Transaction added in v1.0.0 

func (w *Wallet) Transaction(txid types.TransactionID) (modules.ProcessedTransaction, bool)

Transaction returns the transaction with the given id. 'False' is returned if the transaction does not exist.

func (*Wallet) Transactions added in v1.0.0 

func (w *Wallet) Transactions(startHeight, endHeight types.BlockHeight) (pts []modules.ProcessedTransaction, err error)

Unlock will decrypt the wallet seed and load all of the addresses into memory.

func (*Wallet) Unlocked added in v1.0.0 

func (w *Wallet) Unlocked() bool

Unlocked indicates whether the wallet is locked or unlocked.

type WalletPersist added in v1.0.0 

type WalletPersist struct {
	// EncryptionVerification is an encrypted string that, when decrypted, is
	// 32 '0' bytes. The UID is used to prevent leaking information in the
	// event that the same key gets used for multiple wallets.
	UID                    UniqueID
	EncryptionVerification crypto.Ciphertext

	// The primary seed is used to generate new addresses as they are required.
	// All addresses are tracked and spendable. Only modules.PublicKeysPerSeed
	// keys/addresses can be created per seed, after which a new seed will need
	// to be generated.
	PrimarySeedFile     SeedFile
	PrimarySeedProgress uint64

	// AuxiliarySeedFiles is a set of seeds that the wallet can spend from, but is
	// no longer using to generate addresses. The primary use case is loading
	// backups in the event of lost files or coins. All auxiliary seeds are
	// encrypted using the primary seed encryption password.
	AuxiliarySeedFiles []SeedFile

	// UnseededKeys are list of spendable keys that were not generated by a
	// random seed.
	UnseededKeys []SpendableKeyFile
}

WalletPersist contains all data that persists on disk during wallet operation.
