Functions

func NewTxBuilder 

func NewTxBuilder(params *Params, expiryHeight uint32) utxo.TxBuilder

NewTxBuilder returns an implementation the transaction builder interface from the Bitcoin Compat API, and exposes the functionality to build simple Zcash transactions.

Types

type Address added in v0.2.0 

type Address interface {
	btcutil.Address
	BitcoinAddress() btcutil.Address
}

An Address represents a Zcash address.

func DecodeAddress added in v0.2.0 

func DecodeAddress(addr string) (Address, error)

type AddressPubKeyHash 

type AddressPubKeyHash struct {
	*btcutil.AddressPubKeyHash
	// contains filtered or unexported fields
}

AddressPubKeyHash represents an address for P2PKH transactions for Zcash that is compatible with the Bitcoin Compat API.

func NewAddressPubKeyHash 

func NewAddressPubKeyHash(pkh []byte, params *Params) (AddressPubKeyHash, error)

NewAddressPubKeyHash returns a new AddressPubKeyHash that is compatible with the Bitcoin Compat API.

func (AddressPubKeyHash) BitcoinAddress added in v0.2.0 

func (addr AddressPubKeyHash) BitcoinAddress() btcutil.Address

BitcoinAddress returns the address as if it was a Bitcoin address.

func (AddressPubKeyHash) EncodeAddress 

func (addr AddressPubKeyHash) EncodeAddress() string

EncodeAddress returns the string encoding of the payment address associated with the Address value. See the comment on String for how this method differs from String.

func (AddressPubKeyHash) IsForNet 

func (addr AddressPubKeyHash) IsForNet(params *chaincfg.Params) bool

IsForNet returns whether or not the address is associated with the passed bitcoin network.

func (AddressPubKeyHash) ScriptAddress 

func (addr AddressPubKeyHash) ScriptAddress() []byte

ScriptAddress returns the raw bytes of the address to be used when inserting the address into a txout's script.

func (AddressPubKeyHash) String 

func (addr AddressPubKeyHash) String() string

String returns the string encoding of the transaction output destination.

Please note that String differs subtly from EncodeAddress: String will return the value as a string without any conversion, while EncodeAddress may convert destination types (for example, converting pubkeys to P2PKH addresses) before encoding as a payment address string.

type AddressScriptHash added in v0.2.0 

type AddressScriptHash struct {
	*btcutil.AddressScriptHash
	// contains filtered or unexported fields
}

AddressScriptHash represents an address for P2SH transactions for Zcash that is compatible with the Bitcoin Compat API.

func NewAddressScriptHash added in v0.2.0 

func NewAddressScriptHash(script []byte, params *Params) (AddressScriptHash, error)

NewAddressScriptHash returns a new AddressScriptHash that is compatible with the Bitcoin Compat API.

func NewAddressScriptHashFromHash added in v0.2.0 

func NewAddressScriptHashFromHash(scriptHash []byte, params *Params) (AddressScriptHash, error)

NewAddressScriptHashFromHash returns a new AddressScriptHash that is compatible with the Bitcoin Compat API.

func (AddressScriptHash) BitcoinAddress added in v0.2.0 

func (addr AddressScriptHash) BitcoinAddress() btcutil.Address

BitcoinAddress returns the address as if it was a Bitcoin address.

func (AddressScriptHash) EncodeAddress added in v0.2.0 

func (addr AddressScriptHash) EncodeAddress() string

EncodeAddress returns the string encoding of the payment address associated with the Address value. See the comment on String for how this method differs from String.

func (AddressScriptHash) IsForNet added in v0.2.0 

func (addr AddressScriptHash) IsForNet(params *chaincfg.Params) bool

IsForNet returns whether or not the address is associated with the passed bitcoin network.

func (AddressScriptHash) ScriptAddress added in v0.2.0 

func (addr AddressScriptHash) ScriptAddress() []byte

ScriptAddress returns the raw bytes of the address to be used when inserting the address into a txout's script.

func (AddressScriptHash) String added in v0.2.0 

func (addr AddressScriptHash) String() string

String returns the string encoding of the transaction output destination.

Please note that String differs subtly from EncodeAddress: String will return the value as a string without any conversion, while EncodeAddress may convert destination types (for example, converting pubkeys to P2PKH addresses) before encoding as a payment address string.

type Client added in v0.2.0 

type Client = bitcoin.Client

type ClientOptions added in v0.2.0 

type ClientOptions = bitcoin.ClientOptions

func DefaultClientOptions added in v0.2.0 

func DefaultClientOptions() ClientOptions

type GasEstimator added in v0.2.0 

type GasEstimator = bitcoin.GasEstimator

type Params added in v0.2.0 

type Params struct {
	// TODO: We do not actually need to embed the entire chaincfg params object.
	*chaincfg.Params

	P2SHPrefix  []byte
	P2PKHPrefix []byte
	Upgrades    []ParamsUpgrade
}

type ParamsUpgrade added in v0.2.0 

type ParamsUpgrade struct {
	ActivationHeight uint32
	BranchID         []byte
}

type Tx 

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

Tx represents a simple Zcash transaction that implements the Bitcoin Compat API.

func (*Tx) Hash 

func (tx *Tx) Hash() (pack.Bytes, error)

func (*Tx) Inputs added in v0.2.0 

func (tx *Tx) Inputs() ([]utxo.Input, error)

func (*Tx) Outputs added in v0.2.0 

func (tx *Tx) Outputs() ([]utxo.Output, error)

func (*Tx) Serialize 

func (tx *Tx) Serialize() (pack.Bytes, error)

func (*Tx) Sighashes 

func (tx *Tx) Sighashes() ([]pack.Bytes32, error)

func (*Tx) Sign 

func (tx *Tx) Sign(signatures []pack.Bytes65, pubKey pack.Bytes) error

type TxBuilder added in v0.2.0 

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

func (TxBuilder) BuildTx added in v0.2.0 

func (txBuilder TxBuilder) BuildTx(inputs []utxo.Input, recipients []utxo.Recipient) (utxo.Tx, error)

BuildTx returns a simple Zcash transaction that consumes the funds from the given outputs, and sends the to the given recipients. The difference in the sum value of the inputs and the sum value of the recipients is paid as a fee to the Zcash network.

It is assumed that the required signature scripts require the SIGHASH_ALL signatures and the serialized public key: 

builder := txscript.NewScriptBuilder()
builder.AddData(append(signature.Serialize(), byte(txscript.SigHashAll|SighashForkID)))
builder.AddData(serializedPubKey)

Outputs produced for recipients will use P2PKH, or P2SH scripts as the pubkey script, based on the format of the recipient address.
