Functions

func NewBackend

func NewBackend(cfg *asset.BackendConfig) (asset.Backend, error)

NewBackend generates the network parameters and creates a zec backend as a btc clone using an asset/btc helper function.

Types

type Driver

type Driver struct{}

Driver implements asset.Driver.

func (*Driver) DecodeCoinID

func (d *Driver) DecodeCoinID(coinID []byte) (string, error)

DecodeCoinID creates a human-readable representation of a coin ID for Zcash.

func (*Driver) MinBondSize

func (d *Driver) MinBondSize(maxFeeRate uint64) uint64

MinBondSize calculates the minimum bond size for a given fee rate that avoids dust outputs on the bond and refund txs, assuming the maxFeeRate doesn't change.

func (*Driver) MinLotSize

func (d *Driver) MinLotSize(maxFeeRate uint64) uint64

MinLotSize calculates the minimum bond size for a given fee rate that avoids dust outputs on the swap and refund txs, assuming the maxFeeRate doesn't change.

func (*Driver) Name

func (d *Driver) Name() string

Name is the asset's name.

func (*Driver) Setup

func (d *Driver) Setup(cfg *asset.BackendConfig) (asset.Backend, error)

Setup creates the Zcash backend. Start the backend with its Run method.

func (*Driver) UnitInfo

func (d *Driver) UnitInfo() dex.UnitInfo

UnitInfo returns the dex.UnitInfo for the asset.

func (*Driver) Version

func (d *Driver) Version() uint32

Version returns the Backend implementation's version number.

type ZECBackend

type ZECBackend struct {
	*btc.Backend
	// contains filtered or unexported fields
}

ZECBackend embeds *btc.Backend and re-implements the Contract method to deal with Zcash address translation.

func (*ZECBackend) Contract

func (be *ZECBackend) Contract(coinID []byte, redeemScript []byte) (*asset.Contract, error)

Contract returns the output from embedded Backend's Contract method, but with the SwapAddress field converted to Zcash encoding. TODO: Drop this in favor of an AddressEncoder field in the BackendCloneConfig.

func (*ZECBackend) FeeRate

func (be *ZECBackend) FeeRate(context.Context) (uint64, error)

For Zcash, return a constant fee rate of 10 zats / byte. We just need to guarantee the tx get over the legacy 0.00001 standard tx fee.

func (*ZECBackend) ValidateFeeRate

func (be *ZECBackend) ValidateFeeRate(ci asset.Coin, _ uint64) bool

func (*ZECBackend) ValidateOrderFunding

func (*ZECBackend) ValidateOrderFunding(swapVal, valSum, inputCount, inputsSize, maxSwaps uint64, _ *dex.Asset) bool
