Watchtower

Production monitoring dashboard for deployed Soroban smart contracts.

Watchtower gives you operational visibility into your contracts after deployment — real-time invocation tracking, decoded error monitoring, resource consumption trends, storage TTL health, cost attribution, and multi-channel alerting.

• Real-time invocation tracking: Live feed of every function call with caller, status, and resource footprint.
• HostError decoding: Translates cryptic Soroban error codes into human-readable causes and remediations.
• Resource consumption analytics: Track CPU instructions, memory bytes, and ledger reads/writes per function.
• Storage TTL health: Continuous monitoring of storage entries with renewal cost estimates.
• Cost attribution: Aggregated daily/weekly/monthly costs broken down by function and storage.
• Multi-channel alerting: Get notified via Slack, PagerDuty, or Discord when errors spike or state approaches expiration.

Watchtower continuously ingests data through two sources:

1. Soroban RPC: For real-time events and transaction details.
2. Mercury API: For historical depth and resilience fallback.

Dashboard Views

• Invocations: Live stream of function calls with heatmaps.
• Errors: Percentage-based error tracking with decoded host errors.
• Resources: Percentile bands (p50, p95, p99) for compute and storage usage.
• Storage: Color-coded TTL status for all tracked storage keys.
• Costs: Burn rate trend lines and budget utilization gauges.

| Channel | Integration | | :--- | :--- | | Slack | Incoming webhooks with rich formatting | | PagerDuty | Events API v2 for on-call escalation | | Discord | Webhook integration | | Email | Digest and critical alert delivery | | Telegram | Bot API integration | | Webhook | Generic HMAC-signed JSON payloads |

Watchtower is read-only. It never requires or stores any Stellar secret keys. All data is encrypted in transit via HTTPS, and team access is managed through RBAC.
