- `POLYGON_WSS_URLS` (optional, comma-separated)
### Proxy support
The bot supports HTTP(S) proxies for both HTTP requests (fetch) and WebSocket connections.
Supported env vars (standard):
- `HTTPS_PROXY` / `https_proxy`
- `HTTP_PROXY` / `http_proxy`
- `ALL_PROXY` / `all_proxy`
Examples:
PowerShell:
```powershell
$env:HTTPS_PROXY = "http://127.0.0.1:8080"
# or
$env:ALL_PROXY = "socks5://127.0.0.1:1080"
```
CMD:
```cmd
set HTTPS_PROXY=http://127.0.0.1:8080
REM or
set ALL_PROXY=socks5://127.0.0.1:1080
```
## Run
```bash
package-lock.json
