Nice job. I like your focus on fees. I usually rely on something like mempool.space for double checking my wallet fee estimation, and I could see a simple, clean site that just focuses on fees doing a great job of filling that need.

(Fwiw, the mempool fee histogram didn't load properly for me on Firefox, Brave, or on my mobile). It looked like the vertical size of the frame it was in was only 5 or 10 pixels or something).
