Height: 158 px fits most layouts; on very narrow columns (under 380 px) the widget switches to two rows — use height="260" there.
What the widget shows
- Next block, 30 minutes, 1 hour and economy fee rates in sat/vB, from the live mempool.
- Approximate cost in USD of a typical payment (one input, two outputs, ~141 vB) at each rate.
- A LOW / NORMAL / HIGH label so readers can see at a glance whether now is a good time to send.
- How many transactions are waiting in the mempool.

Frequently asked questions
Does the widget slow down my site?
No. It loads lazily in an iframe, weighs a few kilobytes, makes one small request every 30 seconds while visible, and sets no cookies.
Can I change the colours?
Add ?theme=light to the iframe address for the light version, or use the default dark theme.
Does it track my visitors?
No cookies and no personal data. We only count, anonymously, how many times widgets are displayed in total.
