Project Overview

What is SoroScan?

SoroScan is a Stellar Soroban event indexer and monitoring platform that:

  • 🔍 Indexes smart contract events from Soroban ledger in real-time
  • 📊 Provides GraphQL and REST APIs for event querying
  • 🪝 Delivers events via webhooks to third-party systems
  • 📈 Tracks contract lifecycle, invocations, and dependencies
  • 🔐 Verifies contract source code and bytecode integrity
  • 📱 Exposes multi-tenant operations dashboard for enterprises

Target Users

  • Blockchain developers monitoring contract events
  • DeFi platforms syncing events to data warehouses
  • Enterprises tracking compliance and audit trails
  • Operators managing Soroban network monitoring infrastructure

Key Differentiators

✅ Production-grade — 81% test coverage, clean migrations, 265 passing tests
✅ Enterprise-ready — Multi-tenancy, GDPR compliance, HA/DR
✅ Developer-friendly — Interactive API docs, SDKs (Python, TypeScript), Webhooks
✅ Retro aesthetic — Terminal-inspired UI with phosphor green on deep black
✅ Comprehensive — 168 fully-documented issues across backend & frontend
