The project's README from github.com/Lavagroabide/aegis-spreadwatch. As one markdown file: README.md.
Aegis SpreadWatch is a native, local-first CS2 trading workspace for people who want the numbers to stay legible. It separates market opportunities, account access, buy plans and fee assumptions into calm, purpose-built workspaces instead of one overloaded dashboard.
The UI ships with a deterministic 15-item market fixture so the terminal is useful immediately in development. Venue requests are isolated behind Rust commands and can be connected to authenticated adapters without changing the React surface.
One zip, attached to the latest release. It carries Main.exe, its update
settings and the Aegis SpreadWatch runtime, so nothing else has to be installed:
| System | File |
|---|---|
| Windows 10 and 11 | aegis-spreadwatch.zip |
Unpack the whole folder and start Main.exe. No installer, no admin rights.
Main.exe is code-signed, so Windows starts it without a warning. Keep
Aegis SpreadWatch next to it: they ship together.
| Workspace | Purpose | Primary action |
|---|---|---|
| Spread scanner | Compare executable buy/sell opportunities | Inspect the net-return calculation |
| Account vaults | Review inventory, access and local Steam Guard codes | Import a vault for the current session |
| Buy orders | Keep acquisition limits and bid position visible | Create a local order plan |
| Connections & fees | Set the assumptions behind every estimate | Save a fee model or endpoint profile |
Aegis treats every venue as a separate fee and settlement model. The scanner reports the amount that remains after the sell-side fee, not a headline spread.
| Venue | Default fee | Settlement | Role |
|---|---|---|---|
| Steam Community Market | 13.00% | USD | High-liquidity exit reference |
| Buff163 | 2.50% | CNY → USD | Low-fee acquisition venue |
| CSFloat | 2.00% | USD | Float-aware listings |
| Skinport | 12.00% | EUR → USD | Consumer-facing exit venue |
| Waxpeer | 6.00% | USD | Secondary liquidity route |

npm run tauri build
Tauri writes the Windows artifacts under src-tauri/target/release/bundle/. The included GitHub Actions workflow builds and attaches the installer when a v*.*.* tag is pushed.
The backend exposes small, testable commands:
calculate_net_return — normalizes the buy currency, subtracts the sell-side fee and returns net profit plus ROI.generate_totp — decodes a Steam Guard shared secret and emits the five-character Steam code for a 30-second window.load_state / save_state — persist fee models and vault metadata under the Tauri app data directory.fetch_public_price — fetches public Steam market search results through reqwest with rustls.sync_inventories — queues a local inventory synchronization pass for configured vaults.| Scanner | Vaults |
