test_pointer_to_pointer()

Documentation for tests/prague/eip7702_set_code_tx/test_set_code_txs_2.py::test_pointer_to_pointer@20373115.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/prague/eip7702_set_code_tx/test_set_code_txs_2.py::test_pointer_to_pointer --fork Amsterdam

Tx -> call -> pointer A -> pointer B.

Direct call from pointer to pointer is OOG
