 As L2s aim to scale horizontally with more chains (such as the [Optimism Superchain](https://app.optimism.io/superchain) and new [Arbitrum chains](https://docs.arbitrum.foundation/new-arb-chains)), developers will want to compare those chains against both the "base" optimism/arbitrum chains, and Ethereum mainnet.
 
-Sites like [op-geth](https://op-geth.optimism.io/) are excellent for comparing the actual code, but for smart contract and application developers this is too low-level to be easily digestible.

 EVM Diff aims to solve these problems, by allowing you to diff the execution-level specifications of EVM-compatible chains in an easy-to-read format.
 
 ## Status
 
 This project is in the early stages of development, and should not yet be relied on.
 
-The initial goal is to have a full diff between mainnet, Optimism, and Arbitrum, and then expand to other chains from there. Starting with these chains seems ideal because they have good documentation are the most popular L2s (by [TVL](https://l2beat.com/scaling/tvl)).
