waves-sdk

Waves SDK is used to interact with the Waves blockchain, it contains various functions can be used to web3 wallet.

Installation

go get

To obtain the latest version, simply require the project using :

go get -u github.com/ewhal/go-wallet-sdk/coins/waves

Usage

New address

pubKeyHash1, _ := crypto.NewPublicKeyFromBase58("2wySdbAsXi1bfAfMBKC1NcyyJemUWLM4R5ECwXJiADUx")
got, err := GetAddress(MainNetScheme, pubKeyHash1)

Transfer

p1 := "tMUA9XRwPTiUXCTmEvU6kFkqTFKxSpaAFvQwyAT29GR"
senderPublicKey, err := crypto.NewPublicKeyFromBase58(p1)
address, err := types.NewAddressFromString(a2)
waves := types.NewOptionalAssetWaves()
tx := NewUnsignedTransferWithSig(senderPublicKey, waves, waves, 1655401735758, 2000000,
    200000, types.NewRecipientFromAddress(address), []byte("attachment"))
// sign the tx
secretKey, err := crypto.NewSecretKeyFromBase58(s1)
if err := SignTransferWithSig(tx, secretKey); err != nil {
    return
}
idBytes, err := tx.ID.MarshalJSON()

Functions

func GenerateKeyPair

func GenerateKeyPair() (string, string, error)

GenerateKeyPair generates a new key pair.

func GetAddress

func GetAddress(scheme byte, pubKeyHash []byte) (string, error)

GetAddress returns the String WavesAddress from the public key. The scheme is one of the MainNetScheme, TestNetScheme, StageNetScheme or CustomNetScheme. The public key is the base58 encoded string of the public key.

func NewAddressFromBytes

func NewAddressFromBytes(b []byte) (types.WavesAddress, error)

NewAddressFromBytes creates an WavesAddress from the slice of bytes and checks that the result address is valid address.

func NewAddressFromString

func NewAddressFromString(s string) (types.WavesAddress, error)

NewAddressFromString creates an WavesAddress from its string representation. This function checks that the address is valid.

func NewUnsignedTransferWithSig

func NewUnsignedTransferWithSig(senderPK crypto.PublicKey, amountAsset, feeAsset types.OptionalAsset,
	timestamp, amount, fee uint64, recipient types.Recipient, attachment types.Attachment) *types.TransferWithSig

NewUnsignedTransferWithSig creates new TransferWithSig transaction without signature and ID.

func SignTransferWithSig

func SignTransferWithSig(t *types.TransferWithSig, privateKey crypto.SecretKey) error

func ValidAddress

func ValidAddress(addr string) (bool, error)
