UI batch (TASK A/B/C/D): - (A) Clearer 'Will expired' message: shortened will id (8+8 chars) and readable UTC date instead of raw UNIX timestamp; shown in WARNING colour (orange) instead of ERROR (red) in the wizard, as it is an expected step. - (A2) Split the orange message onto two lines via <br> (rendered as HTML by msg_warning) to avoid an overly long single line. - (B) History tab labels (text only): inheritance txs -> 'BAL Inheritance transaction'; invalidate tx -> 'BAL Invalidate transaction'. Colours left to Electrum defaults. - (C) New 'No will-executor TX' checkbox in plugin settings, bound to the existing NO_WILLEXECUTOR config (default ON, kept in sync with the wizard), with help text, and included in the settings reset action. - (D) Wizard button label 'Create your will' -> 'Build Your Will'. Regression fix (A3): - When an heir was added to an already-expired will via the wizard, the automatic invalidation no longer triggered. Root cause: the inner check_will() after build_will() raised WillExpiredException and the handler returned (False, None), which never invalidated. - Auto-opening the invalidation tx window from the closing wizard proved unreliable (the window ended up behind the main wallet on some window managers; a re-check loop could ask to invalidate repeatedly before the tx reached the mempool). The robust fix: close the wizard and show a clear instruction popup guiding the user to run 'Tools -> Invalidate' and then press 'Check' to finish the will. Reasoning documented in the code. Version bumped to 0.3.9 (manifest.json, __init__.py, plugin_base.py, VERSION). CHANGELOG entry #15 updated. Verified: py_compile OK, ruff clean (no new errors), full test suite 239 passed.
BAL — Bitcoin After Life (Electrum plugin)
Free and decentralized Bitcoin inheritance support for the Electrum wallet. Build time-locked "will" transactions that transfer your funds to your heirs if you stop refreshing them (dead-man's switch), optionally relayed by will-executor servers.
This repository contains a behavior-preserving refactor of the original plugin. The logic was kept byte-identical wherever possible; only the file layout was reorganized to cleanly separate business logic from the PyQt GUI.

build_zip.py builds a clean, zipimport-friendly distribution zip
tests/ smoke + external-zip regression tests
Requirements
- Electrum 4.7.2 — the last stable release exposing
json_db.register_dict, which this plugin relies on. Newer versions removed it. - PyQt6 (bundled with the Electrum desktop GUI).
Installation
Build the distribution archive
python3 build_zip.py
# -> bal-electrum-plugin.zip (prints size + SHA-256 for integrity checks)
The builder writes a zipimport-friendly archive (files only, standard
DEFLATE, deterministic order) to avoid loader errors seen on some Electrum
portable builds.
Install as an external plugin (zip)
- Electrum → Tools → Plugins → install from file → pick the built zip.
- Enable Bitcoin After Life and restart Electrum.
- (Recommended) verify the downloaded zip's SHA-256 matches the value printed
by
build_zip.py.
Install as an internal plugin
Copy the bal/ directory into your Electrum installation's
electrum/plugins/ directory, so that electrum/plugins/bal/manifest.json
exists, then enable it from Tools → Plugins.
Inheritance safety: anticipate / postpone
A will transaction is signed with a fixed, immutable locktime and then optionally sent to will-executor servers, which are economically incentivised to broadcast it (they collect fees). Because the locktime is baked into the signed transaction, simply changing the delivery time later is not enough: the old, already-signed transaction keeps living on the will-executors.
The plugin handles the two cases as follows (triggered when you press Tools → Prepare):
- Anticipate (new delivery time earlier than the signed locktime): the will is treated as expired and you are asked to invalidate the old transaction on-chain, then rebuild.
- Postpone (new delivery time later than the signed locktime) on a will
that was already signed and/or pushed: the previously committed coins
must be invalidated on-chain first, otherwise a will-executor could
broadcast the old (earlier-locktime) transaction and execute the inheritance
too early. The plugin detects this by comparing the requested locktime with
the locktime frozen inside the signed transaction (
tx.locktime), and asks you to sign and broadcast an invalidation transaction. After it is broadcast, press Prepare again to rebuild, re-sign and re-send the new (postponed) inheritance. Postponing a will that was never signed/sent just rebuilds it (no on-chain fee).
Transaction list: the "Server" column
The will transaction list shows a dedicated Server column so you always know whether each inheritance transaction is actually stored on the will-executor servers, independently of the row colour:
| Label | Meaning |
|---|---|
Confirmed on server |
the will-executor confirmed it stored the transaction |
Sent (not checked) |
pushed to the will-executor, not yet re-checked |
Send failed / Not on server |
push failed or the server no longer has it |
Signed (not sent) |
signed locally, not sent to any will-executor |
Not sent |
not signed/sent yet |
Hovering the cell shows a tooltip with the will-executor URL and the current state.

⚠️ Safety
This plugin builds real Bitcoin inheritance transactions with time-locks. Test on testnet or a fund-less wallet first, and review the generated transactions before broadcasting.
