Scenario 3: Relay Failover

Situation: relay.damus.io goes offline

User's Experience

T=0   - User sends "JPY BUY @bisqbot"
T=100 - Event arrives at relay.nostr.band (first)
T=200 - Event arrives at nos.lol (second)
T=250 - Bot receives from relay.nostr.band (doesn't wait for damus)
T=300 - Process continues normally
T=400 - Response published to relay.nostr.band and nos.lol
T=500 - damus comes back online, finds response from relay.nostr.band
T=600 - User receives response normally

Result: No service interruption. Bot gracefully handled relay failure.

Scenario 6: Multi-Relay Publishing

One Response, Multiple Destinations

User sends: USD BUY @bisqbot

Bot publishes to all relays simultaneously:

Bot creates event:
{
  "kind": 1,
  "content": "**Bisq USD BUY Offers** (Top 10)...",
  "tags": [["e", "user_event_id"], ["p", "user_pubkey"]]
}

Publishes to:
  ✓ wss://relay.nostr.band    (50ms)
  ✓ wss://relay.damus.io      (45ms)
  ✓ wss://nos.lol             (60ms)

Event ID: abc123xyz...

Event Propagation

relay.damus.io              relay.nostr.band            nos.lol
     ↓                           ↓                         ↓
Stores event         Stores event + indexing      Stores event
     ↓                           ↓                         ↓
Notifies subscribers    Notifies subscribers    Notifies subscribers
     ↓                           ↓                         ↓
User sees response   User sees response      User sees response

Result

User can find response regardless of which relay they're connected to.

Scenario 7: Command Variations

Same data, multiple ways to request it:

Request Format Variations

All of these produce the same result:

Simple:         USD BUY @bisqbot
Verbose:        Get USD buy offers @bisqbot  
Mixed:          @bisqbot get USD buy
Minimal:        USD BUY
Capitalized:    usd buy
All caps:       USD BUY

All return:

**Bisq USD BUY Offers** (Top 10)
1. 0.4500 BTC @ 43,200 USD...

Parser Flexibility

# All of these parse to the same command:
MessageParser.parse_command("USD BUY", bot_pubkey)
MessageParser.parse_command("usd buy", bot_pubkey)
MessageParser.parse_command("Get USD buy", bot_pubkey)
MessageParser.parse_command("@bisqbot USD BUY", bot_pubkey)
MessageParser.parse_command("USD BUY @bisqbot please", bot_pubkey)

# Result:
ParsedCommand(
  command_type=CommandType.GET_OFFERS,
  currency_code="USD",
  direction="BUY",
  limit=10
)

---

Scenario 8: Thread Navigation

Bot Response Threading

User posts mention → Bot responds with threading tags:

User's event:
{
  "id": "user_event_abc123",
  "content": "USD BUY @bisqbot"
}

Bot's response:
{
  "id": "bot_response_xyz789",
  "content": "**Bisq USD BUY Offers**...",
  "tags": [
    ["e", "user_event_abc123"],  ← Reply to user's event
    ["p", "user_pubkey_here"]     ← Mention user
  ]
}

Result: In threaded view, response appears under user's message.

Scenario 9: Testing & Verification

Developer Testing

# SSH to bot server
ssh bisq@your-server

# Enter bot directory
cd /opt/bisq-bot

# Activate virtual environment
source venv/bin/activate

# Test command parsing
python3 << 'EOF'
from src.message_parser import MessageParser

test_cases = [
    "USD BUY",
    "eur sell",
    "get gbp buy",
    "STATS",
    "help"
]

for test in test_cases:
    class MockEvent:
        content = test
        author = "test_user"
    
    cmd = MessageParser.parse_command(MockEvent(), "bot_pubkey")
    if cmd:
        print(f"✓ '{test}' → {cmd.command_type.value}")
    else:
        print(f"✗ '{test}' → NO MATCH")
EOF

# Output:
# ✓ 'USD BUY' → get_offers
# ✓ 'eur sell' → get_offers
# ✓ 'get gbp buy' → get_offers
# ✓ 'STATS' → get_stats
# ✓ 'help' → help

Live Testing

# Check bot status
sudo systemctl status bisq-bot

# Monitor logs in real-time
journalctl -u bisq-bot -f

# (In another terminal) Mention bot from Nostr client
# Should see immediate logs showing:
# - Event received
# - Command parsed
# - Bisq queried
# - Response published

# Check response was published
journalctl -u bisq-bot | grep "Response published"

---

Scenario 10: Monitoring & Troubleshooting

Regular Health Check

# Check service status
sudo systemctl status bisq-bot
# Expected: active (running)

# Check recent errors
journalctl -u bisq-bot -e
# Expected: No error messages in last 5 minutes

# Check relay connectivity
journalctl -u bisq-bot | grep relay | tail -10
# Expected: "Connected to Nostr relays"

# Verify Bisq accessibility
bisq-cli --port=4848 getoffers --direction=BUY --currency-code=USD
# Expected: JSON output with offers

Troubleshooting Flow

Problem: Bot not responding to mentions

Step 1: Check bot is running
  sudo systemctl status bisq-bot
  # Expected: active (running)

Step 2: Check relay connectivity
  journalctl -u bisq-bot -n 50 | grep -i relay
  # Expected: "Connected to Nostr relays"

Step 3: Check Bisq connectivity
  bisq-cli --port=4848 getoffers --direction=BUY --currency-code=USD
  # Expected: JSON with offers

Step 4: Monitor logs while testing
  journalctl -u bisq-bot -f
  # Mention bot in Nostr client
  # Look for "Received message from..."

Step 5: Check mention format
  # Use bot's public key from logs
  # Format: @pubkey or nostr:npub1...

Performance Examples

Query Performance

Request: "USD BUY @bisqbot"

Network propagation:  50-150ms  (user → relay → bot)
Bot startup:          5-10ms    (async dispatch)
Command parsing:      2-5ms     (regex matching)
Bisq query:           600-1200ms (bisq-cli execution)
Response formatting:  5-10ms    (string building)
Nostr publish:        100-300ms (publish to 3 relays)
Network delivery:     100-300ms (relay → user client)
─────────────────────────────
Total:                2.5-4.5 seconds

Typical: 3 seconds

Concurrent Queries

Simultaneous queries: 10 users asking for offers at same time

Bot behavior:
- All queries start in parallel (async)
- All Bisq queries run in parallel
- Responses published as they complete
- No blocking, no queue

Result:
- All 10 users get response within 3-5 seconds
- No queue delays
- Linear scaling with relay capacity

---

Summary

The Bisq Bot handles a wide range of scenarios efficiently:

✅ Single queries - 2-5 seconds response time ✅ Concurrent queries - All handled in parallel ✅ Relay failures - Automatic failover to others ✅ Daemon issues - Graceful error messages ✅ Invalid input - Silently ignored ✅ High volume - Hundreds per minute ✅ Multi-relay - Event published to all

Real-world users experience a responsive, reliable bot that integrates seamlessly with their Nostr experience.
