Introduction

Today marks a major milestone in our journey to build a decentralized layer for transparent, provable execution.

We’re excited to announce the launch of the Pi Squared VSL devnet, a developer-first environment for building, testing, and exploring the future of composable AI and blockchain infrastructure. This is more than just a testbed. It’s the first real proving ground for the Verifiable Settlement Layer (VSL), our core infrastructure for on-chain state, AI execution, and cross-domain composability.

As we open up access, we’re inviting developers, researchers, and partners to dig into what we believe is the next frontier: programmable, verifiable computing across trust boundaries. From smart agents to mirrored blockchains and secure AI execution, the devnet is where Pi Squared’s vision comes to life.

The devnet is a foundational step on the road to mainnet, and a key part of our mission to make decentralized computation both accessible and programmable. Read on to explore how the devnet works, why it matters, and how you can start building with it today!

What is the VSL Devnet?

The Pi Squared VSL devnet is our first live environment where developers can interact with the foundational layer powering the Verifiable Settlement Layer (VSL).

At its core, VSL is a decentralized network designed to bring scalable, affordable, and customizable verifiability to all corners of Web3. Through a system of VSL claims—statements that encode anything verifiable or provable—participants can securely exchange assets, data, or services across diverse platforms.

These claims are validated by a set of homogeneous VSL validators, then settled on the VSL network with instant finality. Once settled, they become instantly accessible across ecosystems, enabling fast and secure cross-platform coordination.

The VSL devnet gives developers early access to this infrastructure: a chance to test how VSL powers new patterns of decentralized computing, AI orchestration, and blockchain interoperability. 

Inside the VSL Devnet

The Pi Squared VSL devnet consists of the VSL infrastructure, as well as three example applications running on top of it. 

The Core VSL

This is the core VSL network itself. Developers can submit, verify, and settle claims directly on VSL. To do this, we’ll offer core toolings including the VSL explorer, API endpoints, CLI, and docs to help you inspect and interact with settled claims across environments.

The VSL core infrastructure powers a wide range of applications. These include, but are not limited to cross-chain token transfers, blockchain mirroring, and AI + Trusted Execution Environments (TEEs).

Read more about each of these below. 

1. Multichain Interoperability 

This live integration showcases VSL-powered cross-chain asset movement powered by Wormhole, the leading interoperability platform connecting traditional finance and the internet economy.

Developers can send assets across chains and track the verifiable flow through VSL claims, demonstrating how decentralized coordination can be made fast, lightweight, and secure.

2. Blockchain Mirroring

Get a first look at our blockchain mirroring capability.

This demo mirrors the blocks and states of a blockchain into VSL, giving developers a glimpse of what’s coming for partners like MegaETH—our long-term vision for global blockchain state composability.

3. AI + TEEs

Explore the intersection of confidential computing and composable AI agents.

This demo shows how VSL claims can wrap the input/output lifecycle of an AI agent running in a TEE, laying the groundwork for partners like Kite AI, targeting improved confidentiality and integrity of critical code and sensitive data.

Each of these demos is designed to showcase just a glimpse of what’s possible with VSL. While we present three applications: multichain interoperability, mirroring, and AI pipelines, they’re not the limits of what you can build.

These are starting points, not boundaries. We encourage developers to think about how their own applications, systems, or services could leverage VSL’s verifiable infrastructure. 

Beyond the VSL Devnet: What’s next?

The Pi Squared VSL devnet is just the beginning.

Over the next few months, we’ll be deepening the VSL network’s capabilities by expanding decentralization, improving validator coordination, and refining our claim validation flows.

We’re also actively working on features like signature aggregation and multi-client support to make integration seamless across both AI pipelines and blockchain networks.

As we move toward the testnet launch later this year, you can expect:

• Greater decentralization of the VSL validator set
• Expanded client integrations across AI, bridge protocols, and mirrored chains
• Public developer tooling for building with and on top of VSL

Each step gets us closer to a world where verifiability isn’t an afterthought, but it’s built in from the start. And this journey from devnet to Mainnet isn’t just a product roadmap, it’s an open call for builders to shape the future of decentralized computing with us.

Why this matters

Verifiability isn’t just a feature at Pi Squared; it’s our foundation. With Web3 still siloed across chains and ecosystems, we see a different path forward: one where correctness, performance, and trust are built in from the start.

The Pi Squared VSL devnet marks a major milestone toward that future. It’s a first glimpse at a verifiability-first platform that can unify chains, languages, and applications through fast, secure, and programmable infrastructure.

With VSL, we’re building the backbone for developers to move value, data, and logic across ecosystems without centralized intermediaries or unverifiable execution.
