PointerAddress

class cometa.address.pointer_address.PointerAddress(ptr)[source]

Bases: object

Represents a Cardano pointer address.

Pointer addresses indirectly specify the stake key that should control staking for the address. Instead of embedding a stake key directly, they reference a stake key by pointing to a stake key registration certificate location on the blockchain.

__init__(ptr)[source]

Return type:: None

__enter__()[source]

Return type:: PointerAddress

__exit__(exc_type, exc_val, exc_tb)[source]

Return type:: None

__repr__()[source]

Return repr(self).

Return type:: str

classmethod from_credentials(network_id, payment, pointer)[source]

Creates a pointer address from a payment credential and stake pointer.

Parameters:

network_id (NetworkId) – The network (mainnet or testnet).
payment (Credential) – The payment credential controlling spending.
pointer (StakePointer) – The stake pointer referencing a stake key registration.

Returns:

A new PointerAddress instance.

Raises:

CardanoError – If address creation fails.

Return type:

PointerAddress

Example

>>> payment = Credential.from_key_hash("00" * 28)
>>> pointer = StakePointer(slot=5756214, tx_index=1, cert_index=0)
>>> addr = PointerAddress.from_credentials(NetworkId.MAINNET, payment, pointer)

classmethod from_address(address)[source]

Creates a PointerAddress from a generic Address.

Parameters:: address (Address) – A generic Address that must be a pointer address.
Returns:: A new PointerAddress instance.
Raises:: CardanoError – If the address is not a pointer address.
Return type:: PointerAddress

classmethod from_bech32(bech32_string)[source]

Creates a PointerAddress from a Bech32-encoded string.

Parameters:: bech32_string (str) – The Bech32-encoded address string.
Returns:: A new PointerAddress instance.
Raises:: CardanoError – If parsing fails.
Return type:: PointerAddress

classmethod from_bytes(data)[source]

Creates a PointerAddress from raw bytes.

Parameters:: data (bytes | bytearray) – The serialized address bytes.
Returns:: A new PointerAddress instance.
Raises:: CardanoError – If parsing fails.
Return type:: PointerAddress
