What does CallLens do?
CallLens is a free First Fold tool that reads five fixed EVM calldata layouts and explains approval permissions using exact integers. It helps users inspect the fields in supported transaction data without connecting a wallet or querying a blockchain. Input stays in the browser; no runtime AI is used. No account is required, and an offline HTML edition is available. Optional donations do not unlock features. Hosted aggregate usage counts are off by default and require consent. Selector matches are candidate interpretations, not verified contract identity, transaction simulation or a safety verdict.
Who should use CallLens?
EVM developers and people reviewing transaction data are the clearest fit based on how the product is positioned.
