test_sufficient_balance_blob_tx()

Documentation for tests/cancun/eip4844_blobs/test_blob_txs.py::test_sufficient_balance_blob_tx@c17999c0.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_blob_txs.py::test_sufficient_balance_blob_tx --fork Amsterdam

Check that transaction is accepted when user can exactly afford the blob gas specified (and max_fee_per_gas would be enough for current block).

  • Transactions with max fee equal or higher than current block base fee
  • Transactions with and without priority fee
  • Transactions with and without value
  • Transactions with and without calldata
  • Transactions with max fee per blob gas lower or higher than the priority fee
