asyncio-based Electrum client library

Project description

Stratum (electrum-server) Client Protocol library

Uses python3 to be a client to the Electrum server network. It makes heavy use of asyncio module and newer Python 3 keywords such as await and async.

For non-server applications, you can probably find all you need already in the standard Electrum code and command line.


  • can connect via Tor, SSL, proxied or directly

  • filter lists of peers by protocol, .onion name

  • manage lists of Electrum servers in simple JSON files.

  • fully asynchronous design, so can connect to multiple at once

  • a number of nearly-useful examples provided


In examples you will find a number little example programs.

  • send single commands, plan is to make this an interactive REPL

  • stream changes/events for an address or blocks.

  • implements a simplistic block explorer website

  • find all Electrum servers recursively, read/write results to JSON

Version History

  • 0.8.0 Support for ElectrumX protocol 1.4 with some helpers to restore useful functions.

  • 0.7.4 Add actual_connection atrribute on StratumClient with some key details

  • 0.7.3 Not sure

  • 0.7.2 Bugfix: port numbers vs. protocols

  • 0.7.1 Python 2.6 compat fix

  • 0.7.0 Reconnect broken server connections automatically (after first connect).

  • 0.6.0 Various pull requests from other devs integrated. Thanks to @devrandom, @ysangkok!

  • 0.5.3 Documents the build/release process (no functional changes).

  • 0.5.2 Make aiosocks and bottom modules optional at runtime (thanks to @BioMike)

  • 0.5.1 Minor bug fixes

  • 0.5.0 First public release.


  • be more robust about failed servers, reconnect and handle it.

  • connect to a few (3?) servers and compare top block and response times; pick best

  • some sort of persistant server list that can be updated as we run

  • type checking of parameters sent to server (maybe)?

  • lots of test code

  • an example that finds servers that do SSL with self-signed certificate

  • an example that fingerprints servers to learn what codebase they use

  • some bitcoin-specific code that all clients would need; like block header to hash
