Turns the dummy-data AMM UI into a real client of the on-chain LEZ wallet.
Adds a hand-written ui_qml C++ backend (src/AmmUi*) over the core
logos_execution_zone module: create/open a local wallet, create and list
public/private accounts, and a navbar Connect / Connected + account-selector
+ Disconnect flow. Onboarding is password-only (no path picking) with a
per-app wallet at ~/.lee/amm-wallet (override: AMM_WALLET_HOME_DIR);
standalone gets its own wallet, Basecamp shares accounts via adopt-on-start.
Requires Nix with flakes; macOS also needs `sandbox = false` (the default).
The logos_execution_zone input is pinned to a module rev whose LEZ (lssa)
already includes the macOS Metal-build fix, so no `--override-input` is
needed — plain `nix run .` works:
cd apps/amm
nix run .
- create_new now returns the new wallet's BIP39 mnemonic (not an int status);
the app currently discards it, so the wallet can't yet be recovered. Surfacing
it in onboarding (+ restore_storage) is a follow-up.
- The wallet password is currently a no-op upstream (storage.rs: "TODO: use
password for storage encryption"); storage.json is plaintext. So Disconnect
is a UI-level lock and reconnect does not (cannot yet) re-prompt for it.
- wallet-ffi requires explicit config/storage paths; a *_default() FFI would
let the app drop its path handling.
- Bundled network config: connects to whatever WalletConfig::default() points
at; real testnet endpoints still TBD.

# 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 wallet FFI requires explicit `config_path`/`storage_path` even
|
|
> though the wallet crate already defines defaults (`~/.lee/wallet`,
|
|
> `from_path_or_initialize_default`). A `wallet_ffi_create_new_default()` /
|
|
> `_open_default()` upstream would let the app drop its path handling entirely.
|
|
|
|
## 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
|
|
```
