Fix transaction sign with Ledger hw #57
Conversation
WalkthroughThe recent updates in the Electrum Dash Ledger plugin focus on enhancing the Changes
Sequence Diagram(s)Refactored getTrustedInput Method: sequenceDiagram
participant Client as Ledger_Client
participant Tx as Transaction
Client->>Tx: getTrustedInput(transaction, index)
Tx-->>Client: Fetch DIP2 extra data block size limits
Client->>Tx: Adjust locktime processing
Tx-->>Client: Return trusted input
Updated sign_transaction Method: sequenceDiagram
participant Client as Ledger_Client
participant Tx as Transaction
participant Addr as constants.net.ADDRTYPE_EXP2PKH
Client->>Tx: sign_transaction(tx, password)
alt Existing address types
Client->>Tx: Process with current logic
else New address type
Client->>Addr: Check for ADDRTYPE_EXP2PKH
Addr-->>Client: Provide necessary details
end
Tx-->>Client: Transaction signed

140-145: Handle DIP2 extra data block size limits correctlyThe code correctly checks if the size of the DIP2 extra data block exceeds the limit. However, consider using a constant for the limit value for better readability and maintainability.
DIP2_EXTRA_DATA_LIMIT = 255 if len(transaction.extra_data) > DIP2_EXTRA_DATA_LIMIT - len(transaction.lockTime):
290-292: Support for additional address typeThe code now supports
constants.net.ADDRTYPE_EXP2PKHin thesetAlternateCoinVersionsmethod. Ensure that this address type is correctly handled throughout the codebase.Verification successful
Support for additional address type
The code now supports
constants.net.ADDRTYPE_EXP2PKHin thesetAlternateCoinVersionsmethod and includes a conditional check to handle this new address type. The new address type appears to be correctly handled in the codebase.

Ensure proper handling of APDU command
The
transaction.lockTimeandparamsare correctly formatted and validated before concatenation into the APDU command. This is evidenced by the checks and handling within thegetTrustedInputmethod, including validation oftransaction.extra_datalength and proper construction ofparams.
