Types

type Key

type Key struct {
	Key       []byte
	ChainCode []byte
}

func DeriveForPath

func DeriveForPath(path string, seed []byte) (*Key, error)

DeriveForPath derives key for a path in BIP-44 format and a seed. Ed25119 derivation operated on hardened keys only.

func NewMasterKey

func NewMasterKey(seed []byte) (*Key, error)

NewMasterKey generates a new master key from seed.

func (*Key) Derive

func (k *Key) Derive(i uint32) (*Key, error)

func (*Key) PublicKey

func (k *Key) PublicKey() ([]byte, error)

PublicKey returns public key for a derived private key.

func (*Key) RawSeed

func (k *Key) RawSeed() [32]byte

RawSeed returns raw seed bytes

type SignedMessageSerializedSig

type SignedMessageSerializedSig struct {
	Message   string `json:"message"`
	Signature string `json:"signature"`
}

type Signer

type Signer struct {
	PriKey  ed25519.PrivateKey
	PubKey  ed25519.PublicKey
	Address string
}

func NewSigner

func NewSigner(seed []byte) *Signer

func NewSignertWithMnemonic

func NewSignertWithMnemonic(mnemonic string) (*Signer, error)

func (*Signer) SignMessage

func (s *Signer) SignMessage(data string, scope constant.IntentScope) (*SignedMessageSerializedSig, error)

func (*Signer) SignPersonalMessage

func (s *Signer) SignPersonalMessage(message string) (*SignedMessageSerializedSig, error)

func (*Signer) SignTransaction

func (s *Signer) SignTransaction(b64TxBytes string) (*models.SignedTransactionSerializedSig, error)
