Early Access
Get early access to production-grade contract monitoring
You run the protocols. We watch the contracts. Sentinel gives Web3 ops teams real-time visibility into the events that matter — before they become incidents.
What Sentinel monitors for your team
-
Large transfers Every token transfer above your threshold, flagged and routed to your ops channel within 15 seconds.
-
Ownership changes OwnershipTransferred events catch admin key rotations, multisig changes, and contract upgrades the moment they land on-chain.
-
Pause / unpause events Protocol emergency stops, circuit breaker toggles, and pause state changes — surfaced immediately to your on-call.
-
Multi-chain coverage Ethereum, Arbitrum, Base, Polygon, and Optimism — one dashboard, one alerting policy, no duplicated configuration.
