Functions

func IntentWithScope

func IntentWithScope(intentScope IntentScope) []int

Types

type AppId

type AppId int

const (
	Sui AppId = 0
)

type IntentScope

type IntentScope int

const (
	TransactionData    IntentScope = 0
	TransactionEffects IntentScope = 1
	CheckpointSummary  IntentScope = 2
	PersonalMessage    IntentScope = 3
)

type IntentVersion

type IntentVersion int

const (

)

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 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)
