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.
