Multi-Relay Design (Key Feature)

Connection Model

The bot connects to multiple relays simultaneously and in parallel:

Configuration:
NOSTR_RELAYS=wss://relay.damus.io,wss://relay.nostr.band,wss://nos.lol

Bot creates:
┌─────────────────────────────────────────────┐
│  NostrHandler (single client instance)      │
│  ├── RelayOptions: read=true, write=true    │
│  ├── add_relay: relay.damus.io              │
│  ├── add_relay: relay.nostr.band            │
│  └── add_relay: nos.lol                     │
└─────────────────────────────────────────────┘

Benefits

  1. No Relay Dependency

    • Bot doesn't need to run a relay
    • Uses existing public relay infrastructure
    • Zero relay setup overhead
  2. Parallel Operations

    • Connect to all relays simultaneously
    • Read from fastest relay
    • Publish to all relays for redundancy
    • Event deduplication prevents duplicates
  3. Automatic Failover

    • If one relay fails, bot continues with others
    • Graceful degradation
    • Automatic reconnection with backoff
  4. Flexibility

    • Add/remove relays by editing .env
    • No code changes needed
    • Scale from 1 to 10+ relays

Configuration Options

Minimal (1 relay):

NOSTR_RELAYS=wss://relay.nostr.band

Recommended (3 relays):

NOSTR_RELAYS=wss://relay.nostr.band,wss://relay.damus.io,wss://nos.lol

High-performance (4-5 relays):

NOSTR_RELAYS=wss://relay.nostr.band,wss://relay.damus.io,wss://nos.lol,wss://offchain.pub,wss://nostr.wine

Performance & Reliability

Response Characteristics

Metric Value Notes
Connection time 2-5s All relays parallel
Query latency 1-3s Via bisq-cli
Response time 2-10s Typically 3-5s
Throughput 1000s/day Per relay
Memory usage ~50 MB Base + cache
CPU usage <5% Async, non-blocking

Reliability Features

Error Recovery

  • Bisq daemon offline → "Bisq unavailable" message
  • Relay failure → Continue with other relays
  • Parse error → Graceful error message
  • Timeout → Return error within 10 seconds

Event Deduplication

  • Same event from multiple relays → Processed once
  • Configurable dedup cache (10,000 events)
  • Prevents duplicate responses

Graceful Degradation

  • Single relay down → Service continues
  • Multiple relays down → Service continues
  • Bisq down → Users informed
  • All relays down → Service waits, doesn't crash

Installation & Setup

cd /opt
sudo git clone <repo> bisq-bot
cd bisq-bot/bot
sudo bash setup.sh

Takes 2 minutes, handles all dependencies.

Manual

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
cp config/.env.example .env
# Edit .env with your private key
python -m src.bot

Production (systemd)

sudo systemctl enable bisq-bot
sudo systemctl start bisq-bot
sudo systemctl status bisq-bot
journalctl -u bisq-bot -f  # Monitor logs

Testing & Verification

Bot Connectivity

# Check Nostr connection
journalctl -u bisq-bot | grep relay

# Check Bisq connection
bisq-cli --port=4848 getoffers --direction=BUY --currency-code=USD

Live Testing

  1. Find bot's public key: journalctl -u bisq-bot -n 5 | grep pubkey
  2. Open Nostr client (Snort.social, Iris.to, etc.)
  3. Mention bot: @bisqbot USD BUY
  4. Wait 2-5 seconds for response

Command Testing

from src.message_parser import MessageParser
cmd = MessageParser.parse_command(event, bot_pubkey)
print(f"Command: {cmd.command_type}, Currency: {cmd.currency_code}")
