 ### Added
 
-- Added Hbar object support for TransferTransaction HBAR transfers: methods now accept Union[int, Hbar] for amount parameters, with immediate normalization to tinybars- includes comprehensive unit tests covering various Hbar units (HBAR, MICROBAR, NANOBAR, TINYBAR) and accumulation behavior with mixed int and Hbar inputs.
