About the product

What does ChainKit do?

ChainKit is a First Fold project with four deterministic, non-AI tools: EVM/TRON address syntax and checksum checks, character-by-character address comparison, exact token-unit conversion and equal-share arithmetic. Inputs are processed locally in the browser. All features are free, with no account or wallet connection and optional donations that do not unlock features. A downloadable offline HTML edition is available. Hosted usage measurement is optional and off by default; it records aggregate counts without tool inputs or session replay. Address validity does not verify the owner, balance, asset or network, and no result authorizes a transfer.
