ergo_addr

Module for Ergo address encoding/decoding.

class ErgoAddressTypes(value)

Bases: IntEnum

Enumerative for Ergo address types.

P2PKH = 1

P2SH = 2

class ErgoNetworkTypes(value)

Bases: IntEnum

Enumerative for Ergo network types.

MAINNET = 0

TESTNET = 16

class ErgoAddrConst

Bases: object

Class container for Ergo address constants.

CHECKSUM_BYTE_LEN: int = 4

class ErgoP2PKHAddrDecoder

Bases: IAddrDecoder

Ergo P2PKH address decoder class. It allows the Ergo P2PKH address decoding.

static DecodeAddr(addr: str, **kwargs: Any) → bytes

Decode an Ergo P2PKH address to bytes.

Parameters:

• addr (str) – Address string

• net_type (ErgoNetworkTypes) – Expected network type (default: main net)

Returns:

Public key bytes

Return type:

bytes

Raises:

• ValueError – If the address encoding is not valid

• TypeError – If the network tag is not a ErgoNetworkTypes enum

class ErgoP2PKHAddrEncoder

Bases: IAddrEncoder

Ergo P2PKH address encoder class. It allows the Ergo P2PKH address encoding.

static EncodeKey(pub_key: Union[bytes, IPublicKey], **kwargs: Any) → str

Encode a public key to Ergo P2PKH address.

Parameters:

• pub_key (bytes or IPublicKey) – Public key bytes or object

• net_type (ErgoNetworkTypes) – Network type (default: main net)

Returns:

Address string

Return type:

str

Raised:

ValueError: If the public key is not valid TypeError: If the public key is not secp256k1 or the network tag is not a ErgoNetworkTypes enum
