Bitcoin Mainnet (
"bitcoin")Bitcoin Testnet (
"testnet")Bitcoin Regtest (

Electrum Server Configuration
Important: While the package defaults to electrum.blockstream.info:50001 for convenience, we strongly recommend configuring your own Electrum server for production use.
Recommended Approach:
For Production:
Set up your own Fulcrum server for optimal performance and reliability
Use recent Fulcrum versions that support pagination for high-transaction addresses
For Development/Testing:
fulcrum.frznode.com:50001- Generally faster than defaultelectrum.blockstream.info:50001- Default fallback
