EVM Diff is an open source project that has already delivered tangible value to developers:
- Chain metadata, precompiles, predeploys, opcodes, and transaction/signature types are all supported for Mainnet, Arbitrum, and Optimism.
- ABIs and logic contract addresses are included for predeploys that are behind proxies.
- References are included for all data.
- A caniuse.com-like view can be found at https://evmdiff.com/features so users can diff a specific feature (such as PUSH0 support) across all chains at once. 
- More data will be added (the full set is tracked at https://github.com/mds1/evm-diff/issues), more chains will be added, and more features will be supported for the /features page.

The above status of the project and corresponding roadmap demonstrates how this project advances the Ethereum ecosystem.
