Blockchain Platform

Sentinel is built natively on the Metis Layer 2 blockchain, leveraging its advanced infrastructure to deliver real-time, AI-enhanced smart contract security. Metis is an Ethereum Layer 2 Optimistic Rollup protocol that combines scalability, decentralization, and modularity — but what sets it apart for Sentinel is its deep integration with AI inference and its support for decentralized AI execution through ALITH.

Why Metis?

Metis is uniquely positioned to support Sentinel's architecture for three core reasons:

1. AI-Native Infrastructure via ALITH
   Metis is the first Layer 2 to support decentralized artificial intelligence at the protocol level. Through ALITH (Autonomous Layer for Inference, Training, and Heuristics), Sentinel is able to run and coordinate AI models natively on-chain — not as external oracle calls or off-chain computation, but as composable, verifiable processes within the Metis stack. This enables low-latency, high-frequency analysis of smart contracts and on-chain behavior, a fundamental requirement for continuous security monitoring.

2. Inference Layer Integration
   At the heart of Sentinel’s detection system is the AI Inference Layer — a framework that allows for real-time evaluation of smart contract code and behavior against a database of known and evolving threats. Metis's modular compute layer provides the low-cost, high-throughput environment needed to support such inference operations, while maintaining EVM compatibility and settlement on Ethereum L1. This allows Sentinel to scale its security engine horizontally without compromising decentralization or composability.

3. Optimistic Decentralization with Practical Scalability
   Unlike monolithic L1s or rigid rollups, Metis employs a Decentralized Sequencer and modular stack that allows Sentinel to operate with the flexibility and speed needed for AI inference workloads. This is critical for Sentinel’s mission of always-on auditing — continuous threat detection and learning simply isn’t feasible on slower or costlier chains.

Strategic Alignment

Metis isn’t just a deployment target — it’s a foundational part of Sentinel’s architecture. Sentinel leverages:

• Low transaction fees to perform granular contract state sampling
• High throughput to support AI model execution and behavioral tracking
• AΛITH to host AI models in a verifiable, decentralized environment
• Native composability with Ethereum and other L2s for cross-platform relevance

This infrastructure synergy ensures Sentinel is not constrained by the traditional limits of gas, latency, or off-chain dependencies. Instead, it thrives in an environment purpose-built for decentralized intelligence — enabling Sentinel to act as a protocol-native guardian for smart contracts across the Web3 ecosystem.

---

In short, Metis provides the compute layer, AI inference capability, and modular flexibility that Sentinel requires to turn smart contract security into a continuous, intelligent, and self-evolving process — one that can only be delivered on a blockchain platform that itself is built for autonomous, AI-native applications.

Conclusion

By leveraging Metis's unique architecture, Sentinel is positioned to redefine smart contract security — making it not just a feature, but an integral part of the blockchain ecosystem. This partnership ensures that as the landscape evolves, Sentinel remains at the forefront of proactive, AI-driven security solutions for decentralized applications.
