Differences between Ethereum and Base

Base is built to be as compatible as possible to Ethereum, and there are very few differences when it comes to building on Base versus Ethereum.

However, there are still some minor discrepancies between the behavior of Base and Ethereum that you should be aware of when building apps on top of Base.

These minor differences include:

• Flashblocks
• Minimum base fee
• Bridging
• Opcodes
• Address aliasing
• Transaction costs
• Chain Finality
