Problem

The trace_address field was missing for delegatecall inner transactions.

Changes

  • Set trace_address for delegatecall to the caller address (frame.from)
  • Use 32-byte hash format for address fields (64 hex characters)

Why trace_address for delegatecall?

DELEGATECALL executes code from another contract while preserving the original msg.sender. The trace_address field records which contract initiated the delegatecall, which is essential for tracing the actual call chain in proxy contract patterns.
