Functions

func GetHRP

func GetHRP(networkID uint32) string

func SortTransferableInputsWithSigners

func SortTransferableInputsWithSigners(ins []*avax.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/ava-labs/avalanchego/blob/224c9fd23d41839201dd0275ac864a845de6e93e/vms/components/avax/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 []*avax.UTXO, opts ...OpOption) (
		totalBalanceToSpend uint64,
		inputs []*avax.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.
