MetisSDK: Open-Source Infrastructure for Scalable Web3 and AI Chains

As the Web3 ecosystem grows in complexity and ambition, so too must the infrastructure that supports it. At Metis, we’ve always believed that blockchain development should be more accessible, scalable, and forward-looking. Today, we’re excited to unveil the open-source release of the MetisSDK, the foundational toolkit powering the future of the Metis ecosystem including Andromeda, Hyperion, and LazAI.

This launch isn’t just a technical milestone it’s an invitation. We’re opening the doors to developers who are curious, critical, and collaborative to help shape the next era of high-performance, modular blockchain systems.

‍

What Is the MetisSDK?

The MetisSDK is a chain development kit designed to enable the creation of high-performance, customizable blockchain networks with real-time execution, Ethereum compatibility, and AI-native capabilities. It abstracts the complexities of running a performant L2/L3 chain and provides the building blocks to power any decentralized application—from DeFi to AI compute marketplaces.

At its core, the SDK is built on principles of modularity, infinite scalability, and a unified developer experience, making it suitable for both production-grade enterprise chains and experimental deployments by independent developers.

‍

Why Open Source?

We believe that transparency, collaboration, and community-driven innovation are essential for building resilient and secure systems. By open-sourcing the MetisSDK, we aim to:

• Foster developer contributions to accelerate the SDK’s evolution
• Promote code quality and security through peer review and open collaboration
• Lower the barrier to entry for projects building on or alongside Metis
• Drive adoption through real-world experimentation, iteration, and feedback

The codebase is live and publicly accessible on GitHub:
👉 github.com/MetisProtocol/metis-sdk

We encourage developers to explore, contribute, and help shape the future of modular blockchain networks.

A Closer Look: MetisSDK’s Tech Stack

MetisSDK provides a full-stack development environment with tightly integrated components that ensure reliability, speed, and scalability:

‍

1. MetisVM

• A high-performance, Ethereum-compatible virtual machine
• Supports AI-specific execution logic and traditional smart contracts
• Features JIT/AOT compilation, opcode optimization, and execution pooling

‍

2. MetisDB

• A fast, memory-mapped state database with separate state commitment and archival layers
• Supports asynchronous I/O and multi-version concurrency control (MVCC)
• Up to 10x faster sync times and reduced storage overhead

‍

3. Metis Parallel Execution Framework (MPEF)

• Built on a modified Block-STM system
• Enables deterministic, conflict-aware parallel execution
• Improves throughput while maintaining EVM semantics

‍

4. Real-Time Sequencer Nodes

• Low-latency block finality and high throughput
• Supports both centralized and decentralized deployments
• Designed for horizontal scaling with infinite chain throughput potential

‍

5. Modular Chain Deployment

• Deploy custom Layer 2s, Layer 3s, or application-specific chains
• Chains can be tailored for AI, gaming, DeFi, or enterprise use cases
• Native interoperability via the Metis Shared Bridge and account abstraction

‍

What Can You Build with MetisSDK?

MetisSDK is already powering our three core networks:

• Andromeda – Our flagship L2 mainnet, known for its performance and low-cost EVM execution
• Hyperion – A next-gen L2 chain built for real-time parallel execution with AI-first support
• LazAI – A purpose-built AI blockchain featuring decentralized inference, model training, and alignment frameworks

But we’re just getting started.

With MetisSDK, developers can now:

• Deploy AI-native chains with built-in model execution support
• Launch high-throughput DeFi chains with custom sequencer configs
• Build gaming or zk-Rollup testnets with low-latency responsiveness
• Experiment with hybrid consensus models or test new VM designs

‍

Unified Liquidity

Despite the presence of multiple chains within the ecosystem, Metis ensures liquidity remains unified and fluid thanks to its Instant Interoperability Module. This module enables seamless, real-time cross-chain swaps, allowing users and dApps to interact across chains without the need to manually bridge or split liquidity. Through this instant interoperability, liquidity pools on one chain can serve demand on another, effectively consolidating fragmented assets into a single liquidity layer. As a result, Metis becomes a liquidity hub, facilitating capital efficiency, minimizing slippage, and enhancing the user experience across the entire ecosystem.

Built on the Shoulders of Giants

MetisSDK leverages best-in-class tooling from across the Ethereum and Rust ecosystem:

• Alloy – Foundational Rust libraries for EVM compatibility
• Reth – High-performance modular Ethereum client in Rust
• Revm & Revmc – Rust-based EVM with JIT/AOT support
• Pevm – Parallel EVM implementation used in our execution framework

We’re deeply grateful for the work of these projects and aim to contribute back through interoperability, documentation, and performance enhancements.

‍

Looking Ahead: What’s Next for MetisSDK?

We have an ambitious roadmap for 2025 and beyond:

• ZK & Hybrid Rollups – Support for alternative rollup types and one-click deployments
• Restaking Protocols – Shared security via Ethereum validators
• Developer Tooling – Advanced RPCs, node dashboards, custom compilers, and observability tooling
• Security Councils & Governance – On-chain upgradability with community-elected governance
• AI Tooling Layer – Model verification, encrypted compute, and inference marketplaces via LazAI

We are preparing for the future of decentralized computation—and MetisSDK is how we get there.
