Functions

func Create

func Create(db walletdb.DB, pubPass, privPass, seed []byte, params *chaincfg.Params) error

Create creates an new wallet, writing it to an empty database. If the passed seed is non-nil, it is used. Otherwise, a secure random seed of the recommended length is generated.

func CreateWatchOnly

func CreateWatchOnly(db walletdb.DB, extendedPubKey string, pubPass []byte, params *chaincfg.Params) error

CreateWatchOnly creates a watchonly wallet on the provided db.

func CurrentAgendas

func CurrentAgendas(params *chaincfg.Params) (version uint32, agendas []chaincfg.ConsensusDeployment)

CurrentAgendas returns the current stake version for the active network and this version of the software, and all agendas defined by it.

func DisableLog

func DisableLog()

DisableLog disables all library log output. Logging output is disabled by default until either UseLogger or SetLogWriter are called.

func EstimateTxSize

func EstimateTxSize(numInputs, numOutputs int, account uint32) int

EstimateTxSize is the exported version of estimateTxSize which provides an estimate of the tx size based on the number of inputs, outputs, and some assumed overhead.

func FeeForSize

FeeForSize is the exported version of feeForSize which returns a fee based on the provided feeIncrement and provided size.

func UnstableAPI

func UnstableAPI(w *Wallet) unstableAPI

UnstableAPI exposes additional unstable public APIs for a Wallet. These APIs may be changed or removed at any time. Currently this type exists to ease the transation (particularly for the legacy JSON-RPC server) from using exported manager packages to a unified wallet package that exposes all functionality by itself. New code should not be written using this API.

func UseLogger

func UseLogger(logger btclog.Logger)

UseLogger uses a specified Logger to output package logging info. This should be used in preference to SetLogWriter if the caller is also using btclog.

func VerifyMessage

func VerifyMessage(msg string, addr hcutil.Address, sig []byte) (bool, error)

VerifyMessage verifies that sig is a valid signature of msg and was created using the secp256k1 private key for addr.

Types

type AccountBalance struct {
	Account      uint32
	TotalBalance hcutil.Amount

AccountBalance associates a total (zero confirmation) balance with an account. Balances for other minimum confirmation counts require more expensive logic and it is not clear which minimums a client is interested in, so they are not included.

type AccountNotification

type AccountNotification struct {
	AccountNumber    uint32
	AccountName      string
	ExternalKeyCount uint32
	InternalKeyCount uint32

	C chan *AccountNotification
	// contains filtered or unexported fields
}

AccountNotificationsClient receives AccountNotifications over the channel C.

}

ConfirmationNotificationsClient provides confirmation notifications of watched transactions until the caller's context signals done. Callers register for notifications using Watch and receive notifications by calling Recv.

	C chan *MainTipChangedNotification
	// contains filtered or unexported fields
}

MainTipChangedNotificationsClient receives MainTipChangedNotifications over the channel C.

type NextAddressCallOption

type NextAddressCallOption func(*nextAddressCallOptions)

NextAddressCallOption defines a call option for the NextAddress family of wallet methods.

func WithGapPolicyError

func WithGapPolicyError() NextAddressCallOption

WithGapPolicyError configures the NextAddress family of methods to error whenever the gap limit would be exceeded. When this default policy is used, callers should check errors against the apperrors.ErrExceedsGapLimit error code and let users specify whether to ignore the gap limit or wrap around to a previously returned address.

func WithGapPolicyIgnore

func WithGapPolicyIgnore() NextAddressCallOption

WithGapPolicyIgnore configures the NextAddress family of methods to ignore the gap limit entirely when generating addresses. Exceeding the gap limit may result in unsynced address child indexes when seed restoring the wallet, unless the restoring gap limit is increased, as well as breaking automatic address synchronization of multiple running wallets.

This is a good policy to use when addresses must never be reused, but be aware of the issues noted above.

func WithGapPolicyWrap

func WithGapPolicyWrap() NextAddressCallOption

WithGapPolicyWrap configures the NextAddress family of methods to wrap around to a previously returned address instead of erroring or ignoring the gap limit and returning a new unused address.

This is a good policy to use for most individual users' wallets where funds are segmented by accounts and not the addresses that control each output.

type NotificationServer

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

During a chain switch, all removed block hashes are included. Detached blocks are sorted in the reverse order they were mined. Attached blocks are sorted in the order mined.

All newly added unmined transactions are included. Removed unmined transactions are not explicitly included. Instead, the hashes of all transactions still unmined are included.

	C <-chan *TransactionNotifications
	// contains filtered or unexported fields
}

TransactionNotificationsClient receives TransactionNotifications from the NotificationServer over the channel C.

func (*TransactionNotificationsClient) Done
