Functions ¶
func SortTransferableInputsWithSigners ¶
func SortTransferableInputsWithSigners(ins []*lux.TransferableInput, signers [][]ids.ShortID)
SortTransferableInputsWithSigners sorts the inputs and signers based on the input's utxo ID.
This is based off of (generics?): https://github.com/luxfi/node/blob/224c9fd23d41839201dd0275ac864a845de6e93e/vms/components/lux/transferables.go#L202
Types ¶
type Key ¶
type Key interface {
// P returns all formatted P-Chain addresses.
P() []string
// C returns the C-Chain address in Ethereum format
C() string
// Addresses returns the all raw ids.ShortID address.
Addresses() []ids.ShortID
// Match attempts to match a list of addresses up to the provided threshold.
Match(owners *secp256k1fx.OutputOwners, time uint64) ([]uint32, []ids.ShortID, bool)
// Spend attempts to spend all specified UTXOs (outputs)
// and returns the new UTXO inputs.
//
// If target amount is specified, it only uses the
// outputs until the total spending is below the target
// amount.
Spends(outputs []*lux.UTXO, opts ...OpOption) (
totalBalanceToSpend uint64,
inputs []*lux.TransferableInput,
signers [][]ids.ShortID,
)
// Sign generates [numSigs] signatures and attaches them to [pTx].
Sign(pTx *txs.Tx, signers [][]ids.ShortID) error
}
Key defines methods for key manager interface.
type OpOption ¶
type OpOption func(*Op)
func WithFeeDeduct ¶
To deduct transfer fee from total spend (output). e.g., "units.MilliLux" for X/P-Chain transfer.
func WithTargetAmount ¶
type SOpOption ¶
type SOpOption func(*SOp)
func WithPrivateKey ¶
func WithPrivateKey(privKey *secp256k1.PrivateKey) SOpOption
To create a new key SoftKey with a pre-loaded private key.
func WithPrivateKeyEncoded ¶
To create a new key SoftKey with a pre-defined private key.
type SoftKey ¶
type SoftKey struct {
// contains filtered or unexported fields
}
func (*SoftKey) Match ¶
func (m *SoftKey) Match(owners *secp256k1fx.OutputOwners, time uint64) ([]uint32, []ids.ShortID, bool)
func (*SoftKey) PrivKeyHex ¶
func (*SoftKey) PrivateKeyRaw ¶
PrivateKeyRaw returns the private key in hex format
