# AMM UI
|
|
|
|
A QML UI application for the Automated Market Maker (AMM) program.
|
|
|
|
See the [Logos QML UI App Tutorial](https://github.com/logos-co/logos-tutorial/blob/master/tutorial-qml-ui-app.md) for more information.
|
|
|
|
## Wallet / chain integration
|
|
|
|
This app is a `ui_qml` module with a hand-written C++ backend
|
|
(`src/AmmUiBackend.*`, plugin in `src/AmmUiPlugin.*`) that depends on the core
|
|
**`logos_execution_zone`** wallet module. The backend calls the core module's
|
|
wallet FFI through `m_logos->logos_execution_zone.*` and exposes an async QtRO
|
|
surface (`src/AmmUiBackend.rep`) plus an account list model to the QML view.
|
|
|
|
**Onboarding is non-invasive.** The app opens straight to the Trade screen; the
|
|
navbar shows **Connect** (opens a password-only modal) or **Connected** + the
|
|
account selector. There is no path picking — the wallet uses LEZ's canonical
|
|
home, `~/.lee/wallet/` (override with `LEE_WALLET_HOME_DIR`, the same var LEZ
|
|
honors), and its config (`wallet_config.json`) self-initializes.
|
|
|
|
Account/keystore sharing follows the runtime:
|
|
|
|
- **Standalone** (`nix run .`): own core-module instance, but the canonical
|
|
`~/.lee/wallet` keystore is shared with the LEZ wallet UI and any other LEZ
|
|
app on the machine. A previously-created wallet auto-opens on launch.
|
|
- **Inside Basecamp**: the core wallet module is a single shared instance, so on
|
|
startup the backend **adopts** the already-open wallet (see
|
|
`openOrAdoptWallet()`), surfacing **shared** accounts across apps.
|
|
|
|
> Follow-up: the app reconstructs the wallet paths itself because the
|
|
> `logos_execution_zone` module only exposes path-taking `create_new`/`open`.
|
|
> LEZ's wallet FFI now provides path-free variants (`wallet_ffi_create_new_default`,
|
|
> `wallet_ffi_open_default`, plus `wallet_ffi_default_config_path` /
|
|
> `_storage_path` / `wallet_ffi_wallet_exists_default`). Once the module surfaces
|
|
> those over QtRO, the app can drop its `defaultWalletHome/Config/Storage` logic.

|
## Setup
|
|
|
|
This project requires Nix with experimental features enabled. If you haven't already, enable them permanently:
|
|
|
|
```bash
|
|
mkdir -p ~/.config/nix && echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
|
|
```
|
|
|
|
## Running the UI
|
|
|
|
Start the UI with:
|
|
|
|
```bash
|
|
nix run .
|
|
```
|
|
|
|
This builds and runs the application in development mode.
|
|
|
|
## Updating Dependencies
|
|
|
|
To update the pinned versions of dependencies in `flake.lock`:
|
|
|
|
```bash
|
|
nix flake update
|
|
```
