Celestia Labs has acquired Sovereign Labs, the developer of the Sovereign SDK, in a move that broadens its blockchain infrastructure offerings from modular Layer 1 technology to end-to-end blockchain engineering. The transaction also brings Sovereign Labs co-founder Preston Evans into Celestia Labs as Chief Technology Officer, while six members of the Sovereign team join the company. Financial terms of the acquisition were not disclosed.
The acquisition comes as blockchain infrastructure providers compete to support a growing market for application-specific chains. Rather than relying on shared public networks, more projects are building dedicated blockchains optimized for their own applications, prompting infrastructure providers to expand beyond base-layer services into execution and application development.
Key Highlights
- Celestia Labs has acquired Sovereign Labs.
- Preston Evans has been appointed Chief Technology Officer of Celestia Labs.
- Six Sovereign Labs employees are joining Celestia Labs.
- The acquisition integrates the Sovereign SDK into Celestia’s technology portfolio.
- Financial terms of the transaction were not disclosed.

Acquisition Expands Beyond Layer 1 Infrastructure
Before the acquisition, Celestia’s primary focus was modular blockchain infrastructure, particularly data availability technology designed to improve scalability for blockchain networks. Sovereign Labs complements that business by providing software for building application-specific blockchains, enabling Celestia to extend its services into execution environments and application-layer development.
The combined company is positioning itself as an engineering partner capable of supporting organizations throughout the blockchain development process, from infrastructure architecture to deployment of customized blockchain networks.
What Sovereign Labs Adds
Founded in 2021 by Cem Ozer and Preston Evans, Sovereign Labs developed the Sovereign SDK, a framework designed for high-performance application-specific blockchains.
According to the companies, the framework is used by:
- Relay, a cross-chain bridge that has processed more than $8.5 billion in transfers.
- Bullet, a perpetual futures exchange capable of processing more than 30,000 transactions per second with approximately 1.2-millisecond order latency.
- The combined engineering teams also state they have delivered more than 25 production blockchains.
Industry Trend Favors Custom Blockchain Networks
The acquisition reflects a broader shift in blockchain infrastructure rather than an isolated expansion.
Several blockchain applications have moved toward dedicated networks designed around their operational requirements:
- Hyperliquid built its own blockchain to optimize trading latency and order execution.
- Polymarket is migrating to a custom chain to reduce congestion and improve performance.
- Robinhood recently introduced blockchain infrastructure to support tokenized equities.
These examples suggest infrastructure providers are increasingly competing on customization and engineering services instead of only Layer 1 performance, reflecting broader investments in blockchain ecosystems, including blockchain infrastructure in Dubai and other global technology hubs.
Why the Deal Matters
The acquisition changes Celestia’s position in the blockchain infrastructure market in several ways:
- It expands the company’s capabilities beyond modular data availability.
- It adds execution-layer and application-layer engineering expertise.
- It strengthens Celestia’s ability to develop application-specific blockchain networks for enterprise customers.
- It aligns the company with growing demand for customized blockchain deployments.
What Comes Next
The immediate focus will be integrating Sovereign Labs’ technology and engineering team into Celestia Labs while expanding enterprise blockchain development services. Although the strategic direction has been outlined, the companies have not disclosed the acquisition value, transaction structure or integration timeline. Those details are expected to emerge as the integration progresses.
