Celestia Labs, the core engineering team behind the modular Layer 1 blockchain Celestia, has acquired the technology and engineering talent of Sovereign Labs in a move aimed at expanding its capabilities across the entire blockchain technology stack. The acquisition is expected to strengthen Celestia Labs’ ability to deliver end-to-end blockchain development, spanning Layer 1 infrastructure, execution environments, and application layers for enterprises and developers seeking customized blockchain solutions.
The transaction brings together two organizations that have played significant roles in the modular blockchain ecosystem. Celestia Labs stated that integrating Sovereign Labs’ expertise would enhance its ability to build high-performance, application-specific blockchains capable of supporting large-scale decentralized applications.
The acquisition expands Celestia Labs’ engineering capabilities across the full blockchain stack, enabling end-to-end development of customized, high-performance blockchain infrastructure.
The Celestia Foundation, a nonprofit organization that supports the long-term governance, development, and ecosystem growth of the Celestia network under the leadership of Chief Executive Officer and co-founder Mustafa Al-Bassam, will continue supporting the network’s broader ecosystem. Meanwhile, Celestia Labs remains responsible for the engineering and maintenance of the blockchain platform.
According to the company, the combined engineering teams have collectively launched more than 25 production blockchain networks and contributed to the development of widely adopted frameworks for high-performance blockchain infrastructure. Celestia Labs has also secured more than $155 million in funding from investors including Bain Capital Crypto and Coinbase Ventures.
Sovereign Labs Technology Enhances Blockchain Performance
Founded in 2021 by Cem Ozer and Preston Evans, Sovereign Labs has become a key contributor to the Celestia ecosystem through the development of the Sovereign Software Development Kit (SDK), a framework designed for application-specific blockchain deployment. The SDK powers several high-performance blockchain applications, including Relay, a blockchain bridge that has processed more than $8.5 billion in transfer volume, and Bullet, a perpetual futures exchange capable of clearing orders in approximately 1.2 milliseconds while processing more than 30,000 transactions per second.
As part of the acquisition, six members of the Sovereign Labs engineering team have joined Celestia Labs. Preston Evans, co-founder of Sovereign Labs, has been appointed Chief Technology Officer of Celestia Labs.
As this trend accelerates, enterprises will need a full-stack blockchain infrastructure solution that includes a hands-on design and engineering partner.
This acquisition complements our existing technology and expertise so we can fill this gap in the market.

Evans said the combined engineering capabilities would allow the company to provide blockchain infrastructure with greater reliability and scalability than many organizations could develop internally. He added that he intended to build upon Celestia Labs’ existing technological foundation while advancing blockchain infrastructure to support the next generation of decentralized applications.
Growing Demand for Custom Blockchain Infrastructure
The acquisition comes as demand for customized blockchain networks continues to increase across the digital asset industry. Developers are increasingly seeking specialized infrastructure because many general-purpose blockchains face limitations in scalability, throughput, and application-specific optimization.
We started Sovereign with a simple belief: the most serious applications will eventually run on their own chains. The market is now proving that thesis in real time.
Today Sovereign becomes part of Celestia Labs.

Industry examples illustrate this trend. Hyperliquid developed its own blockchain to improve transaction latency and implement customized order execution rules, while prediction market platform Polymarket began migrating to a dedicated blockchain after processing approximately $6 billion in trading volume during the first half of 2025, aiming to address network congestion and improve operational efficiency.
The integration of Sovereign Labs’ technology and engineering talent is intended to position Celestia Labs as a provider of customized blockchain infrastructure for organizations requiring greater scalability, performance, and flexibility than general-purpose networks can offer.
Chief Executive Officer Nick White said internet-scale applications, including AI-driven payment systems, global exchanges, and prediction markets, increasingly require purpose-built blockchain infrastructure supported by experienced engineering teams. He indicated that the acquisition significantly expanded Celestia Labs’ technical capabilities, enabling the company to serve as a comprehensive infrastructure and design partner for enterprises building their own blockchain networks.
By combining expertise in modular blockchain architecture with application-specific engineering, Celestia Labs aims to help enterprises develop tailored blockchain solutions capable of supporting next-generation decentralized applications at scale.
