Functions

func FilterUnconfirmedHeuristic

func FilterUnconfirmedHeuristic[UTXO UtxoI](unspentOutputs []UTXO) []UTXO

func LegacyFeeFilter

func LegacyFeeFilter(chain *xc.ChainConfig, satsPerByte uint64, multiplier float64, maxGasPrice float64) uint64

Previously we would apply multiplier during estimation, rather than during tx-building/serialization. This should be removed with the legacy endpoints.

func MinFeePerByte

func MinFeePerByte(chain *xc.ChainConfig) uint64

Per chain min

Types

type Outpoint

type Outpoint struct {
	Hash  []byte `json:"hash"`
	Index uint32 `json:"index"`
}

A specific output from a transaction

func (*Outpoint) Equals

func (o *Outpoint) Equals(other *Outpoint) bool

type Output

type Output struct {
	Outpoint     `json:"outpoint"`
	Value        xc.AmountBlockchain `json:"value"`
	PubKeyScript []byte              `json:"pubkey_script"`
}

func FilterForMinUtxoSet

func FilterForMinUtxoSet(unspentOutputs []Output, targetAmount xc.AmountBlockchain, minUtxo int) []Output

1. sort unspentOutputs from lowest to highest 2. grab the minimum amount of UTXO needed to satify amount 3. tack on the smallest utxo's until `minUtxo` is reached. This ensures a small number of UTXO are used for transaction while also consolidating some smaller utxo into the transaction. Returns the total balance of the min utxo set. txInput.inputs are updated to the new set.

func NewOutputs

func NewOutputs[UTXO UtxoI](unspentOutputs []UTXO, addressScript []byte) []Output

type TxInput

type TxInput struct {
	xc.TxInputEnvelope
	UnspentOutputs  []Output            `json:"unspent_outputs"`
	FromPublicKey   []byte              `json:"from_pubkey"`
	GasPricePerByte xc.AmountBlockchain `json:"gas_price_per_byte"`
}
