MempoolWatch is a command-line tool written in Rust that shows the current state of the Bitcoin mempool and the fee market.
It helps you see how busy the Bitcoin network is and how much fee you should pay to get a transaction confirmed.
The data is fetched live from the public mempool.space Bitcoin API.
This tool displays:
- Number of unconfirmed transactions in the mempool
- Total mempool size in MB
- Total fees waiting to be mined (in satoshis)
- Recommended fee rates for:
- High priority
- 30 minute target
- 1 hour target
- Low priority
- Minimum relay fee
All fee values are shown in sat/vB (satoshis per virtual byte), which is the real unit used by Bitcoin miners.
