Types

type Keychain 

type Keychain interface {
	// The returned Signer can provide a signature for [addr]
	Get(addr ids.ShortID) (Signer, bool)
	// Returns the set of addresses for which the accessor keeps an associated
	// signer
	Addresses() set.Set[ids.ShortID]
}

Keychain maintains a set of addresses together with their corresponding signers

func NewLedgerKeychain 

func NewLedgerKeychain(ledger Ledger, indices []uint32) (Keychain, error)

NewLedgerKeychain creates a new ledger keychain

type Ledger 

type Ledger interface {
	Address(displayHRP string, addressIndex uint32) (ids.ShortID, error)
	SignHash(hash []byte, addressIndex uint32) ([]byte, error)
	Sign(hash []byte, addressIndex uint32) ([]byte, error)
	SignTransaction(rawUnsignedHash []byte, addressIndices []uint32) ([][]byte, error)
	GetAddresses(addressIndices []uint32) ([]ids.ShortID, error)
	Disconnect() error
}

Ledger interface for hardware wallet support

type Signer 

type Signer interface {
	SignHash([]byte) ([]byte, error)
	Sign([]byte) ([]byte, error)
	Address() ids.ShortID
}

Signer implements functions for a keychain to return its main address and to sign a hash
