nectarbase.signedtransactions module

class nectarbase.signedtransactions.Signed_Transaction(*args: Any, **kwargs: Any)

Bases: Signed_Transaction

Create a signed transaction and offer method to create the signature

Parameters:

• refNum (num) – parameter ref_block_num (see nectarbase.transactions.getBlockParams())

• refPrefix (num) – parameter ref_block_prefix (see nectarbase.transactions.getBlockParams())

• expiration (str) – expiration date

• operations (array) – array of operations

• custom_chains (dict) – custom chain which should be added to the known chains

add_custom_chains(custom_chain: Mapping[str, Any]) → None

Add entries from custom_chain into this transaction’s known chains without overwriting existing entries.

Accepts a mapping of chain identifiers to chain configuration values and merges any keys not already present into self.known_chains. Existing known chains are left unchanged. Parameters:

custom_chain (Mapping): Mapping of chain name -> chain data (e.g., RPC URL or chain parameters); keys present in self.known_chains are not replaced.

getKnownChains() → Dict[str, Any]

getOperationKlass() → type[Operation]

Return the Operation class used to construct operations for this transaction.

Returns:

type: The Operation class used by this Signed_Transaction.

sign(wifkeys: str | List[str], chain: str | Dict[str, Any] | None = None) → Signed_Transaction

Sign the transaction using one or more WIF-format private keys.

wifkeys: Single WIF string or iterable of WIF private key strings used to produce signatures. chain: Chain identifier to use for signing (defaults to “HIVE”).

Returns:

The value returned by the superclass sign implementation.

verify(pubkeys: List[Any] | None = None, chain: str | Dict[str, Any] | None = None, recover_parameter: bool = False) → List[Any]

Verify this transaction’s signatures.

Parameters:

pubkeys (list[str] | None): Public keys to verify against. If None, an empty list is used (all signatures will be checked

without restricting expected pubkeys).

chain (str): Chain identifier to use for verification (defaults to “HIVE”). recover_parameter (bool): If True, return signature recovery parameters alongside verification results.

Returns:

Any: The result returned by the superclass verify method (verification outcome as defined by the base implementation).
