How

Transaction Cast

When the modified construct_sign_and_send_raw_middleware is going to sign a transaction, it will convert an EIP-1559 transaction to conflux transaction following the rule:

• If gasPrice is missing, use maxFeePerGas as gas price.
• Fill epochHeight with w3.eth.block_number, which correspondes to epoch_number in conflux.
• Estimate the transaction and fill storageLimit from estimate result.

Address Cast

EOA account addresses are all converted to begin with 0x1 and is encoded in checksum format
