About this app

Monitor Bitcoin addresses in the mempool and on-chain using the mempool.space API and websocket.

Track balance changes, get telegram notifications, and manage expectations for multiple addresses.

Features:

  • Build list of addresses in collections to sum-up balances accross wallets
  • Subscribes to mempool.space (or locally hosted) websocket for real-time mempool activity
  • Double checks data against mempool.space (or locally hosted) API on a configured interval
  • Track both on-chain and mempool activity
  • Configure auto-acceptance or alert mode of changes (chain_in, chain_out, mempool_in, mempool_out)
    • by default, incoming transactions are auto-accepted, outgoing transactions are alerted
    • all activity is alerted to a configured telegram connection once (even when auto-accepted)
  • Option to use your own local node for privacy

Recommended to have Mempool + Fulcrum to run privately but not required.
