Types

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 NewCustomWallet 

func NewCustomWallet(cs modules.ConsensusSet, tpool modules.TransactionPool, persistDir string, deps modules.Dependencies) (*Wallet, error)

NewCustomWallet creates a new wallet using custom dependencies.

func (*Wallet) AddressTransactions 

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

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

func (*Wallet) AddressUnconfirmedTransactions 

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

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

func (*Wallet) AllAddresses 

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

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 

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

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

func (*Wallet) ChangeKey 

func (w *Wallet) ChangeKey(masterKey crypto.TwofishKey, newKey crypto.TwofishKey) error

ChangeKey changes the wallet's encryption key from masterKey to newKey.

func (*Wallet) Close 

func (w *Wallet) Close() error

Close terminates all ongoing processes involving the wallet, enabling garbage collection.

func (*Wallet) ConfirmedBalance 

func (w *Wallet) ConfirmedBalance() (siaclassiccoinBalance types.Currency, siaclassicfundBalance types.Currency, siaclassicfundClaimBalance types.Currency, err error)

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

func (*Wallet) CreateBackup 

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

CreateBackup creates a backup file at the desired filepath.

func (*Wallet) DustThreshold 

func (w *Wallet) DustThreshold() (types.Currency, error)

DustThreshold returns the quantity per byte below which a Currency is considered to be Dust.

func (*Wallet) Encrypt 

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

Encrypt will create a primary seed for the wallet and encrypt it using masterKey. If masterKey is blank, then the hash of the primary seed will be used instead. The wallet will still be locked after Encrypt is called.

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 

func (w *Wallet) Encrypted() (bool, error)

Encrypted returns whether or not the wallet has been encrypted.

func (*Wallet) Height 

func (w *Wallet) Height() (types.BlockHeight, error)

Height return the internal processed consensus height of the wallet

func (*Wallet) InitFromSeed 

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

InitFromSeed functions like Init, but using a specified seed. Unlike Init, the blockchain will be scanned to determine the seed's progress. For this reason, InitFromSeed should not be called until the blockchain is fully synced.

func (*Wallet) Load033xWallet 

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 

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) LoadSiaClassicgKeys 

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

LoadSiaClassicgKeys loads a set of siaclassicg-generated keys into the wallet.

func (*Wallet) Lock 

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 

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

NextAddress returns an unlock hash that is ready to receive siaclassiccoins or siaclassicfunds. The address is generated using the primary address seed.

func (*Wallet) NextAddresses 

func (w *Wallet) NextAddresses(n uint64) ([]types.UnlockConditions, error)

NextAddresses returns n unlock hashes that are ready to receive siaclassiccoins or siaclassicfunds. The addresses are generated using the primary address seed.

Warning: If this function is used to generate large numbers of addresses, those addresses should be used. Otherwise the lookahead might not be able to keep up and multiple wallets with the same seed might desync.

func (*Wallet) PrimarySeed 

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

PrimarySeed returns the decrypted primary seed of the wallet, as well as the number of addresses that the seed can be safely used to generate.

func (*Wallet) ProcessConsensusChange 

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 

func (w *Wallet) ReceiveUpdatedUnconfirmedTransactions(diff *modules.TransactionPoolDiff)

ReceiveUpdatedUnconfirmedTransactions updates the wallet's unconfirmed transaction set.

func (*Wallet) RegisterTransaction 

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

RegisterTransaction takes a transaction and its parents and returns a modules.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) Rescanning 

func (w *Wallet) Rescanning() (bool, error)

Rescanning reports whether the wallet is currently rescanning the blockchain.

func (*Wallet) Reset 

func (w *Wallet) Reset() error

Reset will reset the wallet, clearing the database and returning it to the unencrypted state. Reset can only be called on a wallet that has already been encrypted.

func (*Wallet) SendSiaClassiccoins 

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

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

func (*Wallet) SendSiaClassiccoinsMulti 

func (w *Wallet) SendSiaClassiccoinsMulti(outputs []types.SiaClassiccoinOutput) (txns []types.Transaction, err error)

SendSiaClassiccoinsMulti creates a transaction that includes the specified outputs. The transaction is submitted to the transaction pool and is also returned.

func (*Wallet) SendSiaClassicfunds 

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

func (*Wallet) SweepSeed 

func (w *Wallet) SweepSeed(seed modules.Seed) (coins, funds types.Currency, err error)

SweepSeed scans the blockchain for outputs generated from seed and creates a transaction that transfers them to the wallet. Note that this incurs a transaction fee. It returns the total value of the outputs, minus the fee. If only siaclassicfunds were found, the fee is deducted from the wallet.

func (*Wallet) Transaction 

func (w *Wallet) Transaction(txid types.TransactionID) (pt modules.ProcessedTransaction, found bool, err error)

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

func (*Wallet) Transactions 

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