417a949037b7c33895e34081d9acd23ddd4a10f8 fix: cache coins for remote backend when loading gui (Michael Mallan)
e03d4e17be937cf49f32a9f3d9d80351d7652a9a refactor: add function to get coins to cache (Michael Mallan)
Pull request description:
With this PR, coins will be cached when first loading a GUI that is using Liana Connect as the backend.
The cache refreshes less often for Liana Connect (every 2 mins), which means there can be a discrepancy between the coins loaded on a page and those in the cache, especially when first loading the GUI with no coins cached.
This can be seen when choosing to refresh a coin in the Coins panel. After selecting the coin and the refresh option, the Self-Send page is displayed with coins listed, but the coin that was previously selected in the Coins panel won't be selected here unless the cache has already refreshed. By caching coins at the start, it makes such a scenario less likely to occur when using Liana Connect.

Liana
The missing safety net for your bitcoins.
About
Liana is a simple Bitcoin wallet. Like other Bitcoin wallets you have one key which can spend the funds in the wallet immediately. Unlike other wallets, Liana lets you in addition specify one key which can only spend the coins after the wallet has been inactive for some time.
We refer to these as the primary spending path (always accessible) and the recovery path (only available after some time of inactivity). You may have more than one key in either the primary or the recovery path (multisig). You may have more than one recovery path.
Here is an example of a Liana wallet configuration:
- Owner's key (can always spend)
- Any 2 keys from the owner's spouse and two kids (after 1 year)
- A third party, in case all else failed (after 1 year and 3 months)
The lockup period is enforced onchain by the Bitcoin network. This is achieved by leveraging timelock capabilities of Bitcoin smart contracts (Script).
Liana can be used for trustless inheritance, loss protection or safer backups. Visit our website for more information.
Usage
Liana is available on Windows, Mac and Linux. To install and start using it see
doc/USAGE.md. A more accessible version of Liana is also available as a web
application here.
If you just want to quickly try out Liana on Bitcoin Signet, see doc/TRY.md.
Hacking on Liana
Liana is an open source project. It is hosted at Github. Contributions are very welcome. See here for guidelines. Most regular contributors hang out on our Discord. Join us there if you have any question about contributing.
Liana is separated in two main components: the daemon and the Graphical User Interface.
Liana daemon
The daemon contains the core logic of the wallet. It is both a library (a Rust crate) that exposes a command interface and a standalone UNIX daemon that exposes a JSONRPC API through a Unix Domain Socket.
The code for the daemon can be found in the liana folder.
Liana GUI
The GUI contains both an installer that guides a user through setting up a Liana wallet, as well as
a graphical interface to the daemon using the iced library.
The code for the GUI can be found in the liana-gui folder.

that could potentially impact the security of users' funds.
