Golang packages for the Simple Ledger Protocol (SLP).

v1parser - for parsing transaction metadata

This package is used for parsing SLP metadata from the SLP transaction's input 0 scriptPubKey.

// here is an example marshaled SLP message extracted from transaction's scriptPubKey.
scriptPubKey := hex.DecodeString("6a04534c500001010453454e4420c4b0d62156b3fa5c8f3436079b5394f7edc1bef5dc1cd2f9d0c4d46f82cca47908000000000000000108000000000000000408000000000000005a")

// get the unmarshaled slp message
slpMsg, err := v1parser.ParseSLP(scriptPubKey)

// do something ...

This usage, here, in BCHD gRPC server provides a good example usage of how to interact with the unmarshaled SLP metadata object.

Differential fuzzer testing has been performed with the slp-validate.js npm package, and can be reproduced following the instructions in the ./fuzz directory.

metadatamaker - for creating new transaction metadata

This package is used for creating marshaled SLP metadata for adding to a transaction's first output scriptPubKey. Helper methods are provided for Type 1, NFT Group, and NFT children transactions.

Genesis - use CreateOpReturnGenesis, NFT1GroupGenesis, or NFT1ChildGenesis

scriptPubKey, err := CreateOpReturnGenesis(
      versionType,
      ticker,
      name,
      documentURL,
      documentHash,
      decimals,
      mintBatonVout,
      quantity,
)

Mint - use CreateOpReturnMint or NFT1GroupMint

scriptPubKey, err := CreateOpReturnMint(
    versionType,
    tokenID,
    vout,
    quantity,
)

Send - use CreateOpReturnSend, NFT1GroupSend, or NFT1ChildSend

scriptPubKey, err := CreateOpReturnSend(
		1,
		tokenID,
		[]uint64{1, 2},
)

Types

type Address

type Address interface {
	// String returns the string encoding of the transaction output
	// destination.
	//
	// Please note that String differs subtly from EncodeAddress: String
	// will return the value as a string without any conversion, while
	// EncodeAddress may convert destination types (for example,
	// converting pubkeys to P2PKH addresses) before encoding as a
	// payment address string.
	String() string

	// EncodeAddress returns the string encoding of the payment address
	// associated with the Address value.  See the comment on String
	// for how this method differs from String.
	EncodeAddress() string

	// ScriptAddress returns the raw bytes of the address to be used
	// when inserting the address into a txout's script.
	ScriptAddress() []byte

	// IsForNet returns whether or not the address is associated with the
	// passed bitcoin network.
	IsForNet(*chaincfg.Params) bool
}

Address is an interface type for any type of destination a transaction output may spend to. This includes pay-to-pubkey (P2PK), pay-to-pubkey-hash (P2PKH), and pay-to-script-hash (P2SH). Address is designed to be generic enough that other kinds of addresses may be added in the future without changing the decoding and encoding API.

func DecodeAddress

func DecodeAddress(addr string, defaultNet *chaincfg.Params, returnBchutilType bool) (Address, error)

DecodeAddress decodes the string encoding of an address and returns the Address if addr is a valid encoding for a known address type.

The result Address type is either bchutil or goslp depending on the value of the forceBchutilType parameter.

The bitcoin network the address is associated with is extracted if possible. When the address does not encode the network, such as in the case of a raw public key, the address will be associated with the passed defaultNet.

type AddressPubKey

type AddressPubKey struct {
	// contains filtered or unexported fields
}

AddressPubKey is an Address for a pay-to-pubkey transaction.

func NewAddressPubKey

func NewAddressPubKey(serializedPubKey []byte, net *chaincfg.Params) (*AddressPubKey, error)

NewAddressPubKey returns a new AddressPubKey which represents a pay-to-pubkey address. The serializedPubKey parameter must be a valid pubkey and can be uncompressed, compressed, or hybrid.

func (*AddressPubKey) AddressPubKeyHash

func (a *AddressPubKey) AddressPubKeyHash() *AddressPubKeyHash

AddressPubKeyHash returns the pay-to-pubkey address converted to a pay-to-pubkey-hash address. Note that the public key format (uncompressed, compressed, etc) will change the resulting address. This is expected since pay-to-pubkey-hash is a hash of the serialized public key which obviously differs with the format. At the time of this writing, most Bitcoin addresses are pay-to-pubkey-hash constructed from the uncompressed public key.

func (*AddressPubKey) EncodeAddress

func (a *AddressPubKey) EncodeAddress() string

EncodeAddress returns the string encoding of the public key as a pay-to-pubkey-hash. Note that the public key format (uncompressed, compressed, etc) will change the resulting address. This is expected since pay-to-pubkey-hash is a hash of the serialized public key which obviously differs with the format. At the time of this writing, most Bitcoin addresses are pay-to-pubkey-hash constructed from the uncompressed public key.
