Differences between Monad and Ethereum

Transactions

1. Transactions are charged based on gas limit rather than gas usage, i.e. total tokens deducted from the sender's balance is value + gas_price * gas_limit. This is a DOS-prevention measure for asynchronous execution. This may be revised before mainnet.

2. Transaction type 2 (EIP-4844 type aka blob transactions) are not supported. This is temporary.
