FAQ

Do I need an API key? Tokens mode: no. Wallets mode: yes, a free Etherscan V2 key at etherscan.io/apis. One key for every EVM chain.

How do I find whale wallets? Nansen smart money lists, Arkham entity pages, or known addresses (Wintermute, Jump, Binance hot wallets). Paste up to 100 per run.

How are USD values resolved? Token price is pulled from DexScreener at scrape time. Stablecoins resolve to $1. Low liquidity tokens may return null and get filtered out.

Can I run this every minute? Yes. Etherscan free tier is 5 calls per second and 100k per day. 50 wallets on 5 chains every minute fits well inside the cap.

Is this allowed? Yes. All data is public onchain and served by licensed providers. Never scrapes a DEX front end.
