143-144: Verify coinbase transaction detection logic.The detection of coinbase transactions is based on the number of inputs and the transaction version. Ensure that this logic is correct and covers all edge cases.
146-147: Ensure correct handling ofextra_datafor coinbase transactions.For coinbase transactions, the
extra_datais directly appended to the buffer. Verify that this is the intended behavior and that it correctly handles all possible sizes ofextra_data.
150-153: Clarifyapducommand construction for non-coinbase transactions.The construction of the
apducommand differs based on whether the transaction is a coinbase transaction or not. Ensure that the logic correctly handles both scenarios and that theblockLengthis appropriately set.
160-161: Verifyextra_datachunk processing for non-coinbase transactions.For non-coinbase transactions,
extra_datais processed in chunks. Ensure that this logic correctly handles all possible sizes ofextra_dataand that theoffsetcalculation is accurate.
164-174: Review loop for processingextra_datain chunks.The loop processes
extra_datain chunks, ensuring that each chunk does not exceed theblockLength. Verify that this logic is robust and correctly handles all edge cases.
