HashGuard
DIY Python auto-optimizer for the Braiins Hashpower marketplace. Monitors the order book, detects stalled bids, and automatically adjusts pricing to maintain hashrate flow while minimizing overpayment.
Features
| Feature | Description |
|---|---|
| Stall detection | If hashrate drops to 0 TH/s, automatically overbids the lowest matching ask by 1 tick (1,000 sats) to restore flow |
| Trim-down | If delivering but overbidding by >4%, trims back to optimal price to save sats |
| Auto-topup | Pre-places a new bid when any active order drops below 20% remaining balance |
| Profitability ceiling | Never bids above hash value + 10% (calculated from live difficulty) |
| Signal alerts | Sends a notification on every action (stall boost, trim, topup) |
| State logging | Tracks actions and daily price lows for trend analysis |
| Secrets management | API keys stored in Bitwarden, decrypted only at runtime |
Architecture
- Runs as a daemon or cron job on a local machine
- Queries Braiins Hashpower API for order book depth and active order status
- Compares delivered hashrate against bid price vs market ask
- Executes bid adjustments via authenticated API calls
- Logs all state transitions to local file for audit
