Built a free whale tracker that monitors 7 major exchange cold wallets totaling over $62B in BTC. Shows live balances, mempool fees, and mining pool stats.

All data sourced from mempool.space. No signup, free API, open access.

Live tracker: https://5.78.129.127.nip.io/whales/

Also built a free URL shortener with analytics: https://5.78.129.127.nip.io/s/

Looking for feedback — what other wallets should I add?
