Relayer Service
planned
Gas-sponsored withdrawals for maximum privacy. User submits ZK proof → relayer validates & executes tx → recipient gets funds minus fee.
All 92 pools supported
Fee: 0.1%–0.5% per pool
msg.sender = relayer (not user)
Latency: ~12s (1 block)
Compatible with stealth addresses
Works on both Sepolia & Arbitrum
📊
Indexer Daemon
in progress
Python daemon monitoring 92 pools across 2 networks. Event streaming, block tracking, reorg handling.
92 pools × 2 networks
Postgres/SQLite storage
Real-time event streaming
Reorg reconciliation
Configurable poll interval
Health monitoring + alerts
🔧
SDK Scanner
built
Python CLI: 5 modules, Web3 v7, Rich terminal. Cross-pool scanning with ViewTag optimization (255×).
pip install zksentinel
zksentinel health --workers 2
zksentinel scan --key <vk>
5 modules (cli, scanner, pools, health, config)
92 pools, 12 tokens
ViewTag client-side filtering
