L2 Bridge Watcher & Validator Nodes

Continuous monitoring of bridge contract states and mempools across all connected chains. We detect and alert on anomalies like double-spend attempts, non-finalized deposits, or invalid merkle proofs within seconds, preventing loss before it occurs.

Out-of-the-box integration with major bridging protocols including Arbitrum Nitro, Optimism Bedrock, zkSync Era, Starknet, and Polygon zkEVM. We handle the complexity of differing consensus mechanisms and proof systems so you don't have to.

Proactive identification of validator misbehavior that could trigger slashing events. Our nodes monitor for equivocation, censorship, and liveness failures, providing actionable alerts to protect your stake and network security.

Configurable alert pipelines via Slack, PagerDuty, Telegram, and direct webhooks to your incident response systems. Define thresholds for transaction volume, failure rates, and balance changes specific to your risk model.

Immutable, queryable logs of all bridge events, validator actions, and system states. Essential for post-mortem analysis, regulatory compliance, and auditing proof of correct operation.

Geographically distributed validator nodes with automatic failover, built on infrastructure with 99.9% uptime SLA. Eliminates single points of failure and ensures your monitoring is always active, even during regional outages.

We analyze your specific L2 bridge architecture and design a custom watcher/validator node deployment plan. This includes selecting optimal cloud providers, defining security perimeters, and establishing monitoring baselines.

Automated, audited deployment of your watcher and validator nodes using infrastructure-as-code (Terraform/Ansible). Nodes are provisioned with hardened OS, secure key management (HSMs/Vault), and private network access.

24/7 monitoring of node health, block synchronization, consensus participation, and RPC endpoint performance. Real-time alerts for slashing risks, missed attestations, or API failures via PagerDuty/Slack.

We manage all node software updates, security patches, and protocol upgrades (hard forks). Our team performs rolling updates to ensure continuous validation without service interruption or slashing risk.

Continuous tuning for latency, gas efficiency, and resource utilization. You receive weekly performance dashboards and monthly operational reports detailing uptime, rewards, and cost efficiency.

Direct access to our blockchain infrastructure engineers via dedicated Slack channel or ticketing system. Includes emergency support for critical incidents and strategic reviews for scaling.
