Celestia Labs Acquires Sovereign Labs to Offer End-to-End Custom Blockchain Builds
Celestia Labs announced today it has acquired Sovereign Labs, the team behind the Sovereign SDK, a Rust-based framework for building application-specific blockchains. The deal, whose financial terms were not disclosed, positions Celestia Labs as a single provider covering both the data availability layer and the chain-building tooling that applications need to move off general-purpose networks.
Sovereign Labs co-founder Preston Evans will become CTO of Celestia Labs. No public statement has addressed what role, if any, co-founder Cem Ozer will hold following the transition. The combined entity is pitching itself as a turnkey partner for companies that want to launch their own high-performance blockchain rather than compete for block space on shared infrastructure.
Why Appchains, Why Now
The acquisition tracks a pattern that has become hard to ignore in recent years.
High-volume applications are leaving shared networks and building their own chains to control throughput, fees, and sequencing. Hyperliquid built a custom derivatives chain and became one of the highest-revenue DeFi protocols in the space. Prediction market platform Polymarket processed $6 billion in volume during the first half of 2025 and is planning a migration off Polygon to its own chain, a move that analysts estimate would strip roughly 56 percent of Polygon's transaction fee revenue. Robinhood launched its own Ethereum-compatible layer-2 network, built on Arbitrum, on July 1 of this year; within two weeks it held $312 million in total value locked and was handling 3.6 million daily transactions across 95 tokenized stocks available in 120+ jurisdictions.
Celestia's announcement cited all three as examples of the market it intends to serve. "This acquisition establishes Celestia Labs as a full-stack custom blockchain development partner for companies building onchain, marking a new chapter for Celestia's go-to-market strategy and ambitions," wrote Nick White of Celestia Labs in the official blog post.
What Sovereign SDK Actually Offers
Sovereign Labs was founded in 2021 and publicly launched in 2023. It raised a $7.4 million seed round in January 2023 led by Haun Ventures, with participation from Maven 11, 1KX, Robot Ventures, and Plaintext Capital. The round drew notable advisors including Balaji Srinivasan, Ethereum core developer Tim Beiko, and EigenLayer founder Sreeram Kannan, a combination that signaled early cross-ecosystem credibility.
The company built an open-source framework allowing developers to deploy application-specific rollups on any layer-1 network or data availability layer, including Celestia. At the time of its seed round, Sovereign Labs stated it had no plans to launch a token and was focused entirely on SDK development; there is no native Sovereign Labs token.
Sovereign SDK's own documentation puts transaction confirmation latency at 1.2 milliseconds, with throughput exceeding 30,000 user operations per second. For comparison, Arbitrum Orbit runs at roughly 100 milliseconds, OP Stack at around 200 milliseconds, Solana at around 200 milliseconds, and the Cosmos SDK at around 400 milliseconds.
The SDK is not a theoretical product. The Relay bridge, built on Sovereign SDK, has settled more than $8.5 billion in cross-chain transfers. A live perpetuals exchange called Bullet, built on the same framework, clears orders in 1.2 milliseconds at over 30,000 transactions per second.
Preston Evans put the developer-access problem plainly in 2023: "Building with zero-knowledge has historically been accessible only to a few PhDs in cryptography. At Sovereign Labs we're building tools which are accessible to normal developers."
TIA Token Context
Celestia's native token, TIA, used to pay for block space on the network and for staking and governance, is trading at approximately $0.41 as of this writing. Readers should verify this figure against a live CoinMarketCap or CoinGecko feed before publication, as the price data is indicative. Market capitalization sits near $374 million, placing TIA at roughly rank 88 on CoinMarketCap. The token has declined sharply from prior cycle peaks. The acquisition had not had time to be reflected in price movements as of this writing.
On the network side, Celestia holds an estimated 50 percent share of the data availability market, according to BlockEden.xyz analysis from earlier this year, and currently supports 37 rollups in production alongside 19 in testnet. The network has processed more than 160 gigabytes of rollup data. Celestia's Fibre architecture, announced in January 2026, targets one terabit per second of throughput across 500 nodes, which the team translates to up to 625 million TPS equivalent. Fibre also introduces the ZODA encoding protocol, which Celestia claims is 881 times faster than the KZG commitment-based alternatives used by competing data availability layers EigenDA and Avail, a technically significant advantage in the DA competitive landscape.
Regional Relevance: South Asia and Africa
For developers outside North America and Europe, this deal has practical implications. India now accounts for 17 percent of all new Web3 developers globally and has seen on-chain value received by Indian users double to $338 billion, according to a 2026 Hashed Emergent report. Indian teams building high-throughput financial applications, including trading infrastructure and real-world asset products, face exactly the scaling constraints the Sovereign SDK addresses. India's regulatory environment is also tightening, with transaction-level reporting requirements taking effect from April 2026, which makes the case for permissioned or compliance-aligned custom chains more practical over time.
In Africa, Celestia does not yet have a significant presence. The continent's most active builder communities cluster around Solana, Base, Stellar, and Lisk, and Celestia does not appear among the 18 blockchain ecosystems cited in ecosystem surveys of Africa's Web3 growth. But the core argument for custom chains maps cleanly onto African use cases: payments, remittances, and financial access applications that need low costs and high throughput. If Celestia Labs follows this acquisition with developer programs, grants, or hackathon partnerships in markets like Nigeria, Kenya, or South Africa, it would be entering territory where it currently has no documented footprint. Whether that absence represents a competitive opening is, at this stage, an analytical inference rather than a documented market condition.
What Comes Next
The combined company now controls the full stack: a data availability layer with roughly half the market and a chain-building framework that, according to Sovereign SDK's own benchmarks, outperforms Arbitrum Orbit, OP Stack, Solana, and the Cosmos SDK on latency. Those benchmarks have not been independently verified by third-party sources. The near-term test is whether Celestia Labs can convert that technical advantage into signed enterprise clients, particularly among the growing number of fintech and DeFi applications that have outgrown shared networks but lack the engineering resources to build custom infrastructure from scratch.
