test_precompile_as_coinbase()

Documentation for tests/frontier/precompiles/test_precompiles.py::test_precompile_as_coinbase@49633827.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/frontier/precompiles/test_precompiles.py::test_precompile_as_coinbase --fork Amsterdam

Verify that an enabled precompile as block coinbase yields a valid state transition.
