Description

Adds an Amsterdam BAL fixture for the case where SYSTEM_ADDRESS is the fee recipient and the transaction priority fee is zero. The expected block access list includes SYSTEM_ADDRESS as an empty account entry because it is still touched by the transaction fee-credit path.

Validation performed:

  • uv run ruff check tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists.py
  • uv run ruff format --check tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists.py
  • uv run pytest tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists.py::test_bal_system_address_coinbase_zero_tip --collect-only -q

Attempted targeted uv run fill ... --fork Amsterdam, but the local WSL run timed out before producing fixture output.
