+# Compatibility
+
+## Wallet types
+
+| Wallet type | Status |
+|---|---|
+| Standard Electrum wallet (seed-based, single-signature) | **Supported** |
+| Hardware wallets supported by Electrum | **Supported** — see [Hardware wallets](hardware-wallets.md) |
+| Multisig wallets | **Not yet supported** — planned for a future release |
+| Electrum TrustedCoin (2FA) wallets | **Unknown / unsupported** — not yet determined |
+
+!!! danger "Do not rely on BAL with multisig or 2FA wallets"
+    If you use a multisig or TrustedCoin (2FA) wallet, do not use BAL for inheritance until compatibility is confirmed.
+
+## Electrum versions
+
+The plugin follows Electrum closely; each release states the Electrum version it was tested against.
+
+| Plugin release | Tested with |
+|---|---|
+| v{{ bal.plugin_version }} | Electrum {{ bal.electrum_tested }} (manual verified on {{ bal.electrum_latest }}) |
+| v0.2.3 | Electrum 4.7.0 |
+| v0.2.0 | Electrum 4.6.2 — introduced the will setup wizard and the remote Will-Executor list |
+| v0.1.0 | Electrum 4.5.8 — first release |
+
+Always check the [releases page](https://bitcoin-after.life/gitea/bitcoinafterlife/bal-electrum-plugin/releases) for the current pairing before upgrading Electrum.
+
+## Networks
+
+The protocol and the servers support **mainnet**, **testnet**, **testnet4**, **signet** and **regtest**. The [WeList](../will-executors/welist.md) lets you filter Will-Executors by network — useful when you want to run a full test before committing real funds.
+
+## Unconfirmed incoming transactions
+
+You can set up an inheritance on a wallet with an **incoming transaction still in the mempool**. It does not need to be confirmed — being visible in the mempool is enough. The plugin handles this case automatically.
