Avail raises $75 million in funding to build highly secure Rollup interoperability and data availability

Avail, a modular blockchain solution that aims to unify Web3 and optimize data availability (DA) for scalable and customized applications, today raised $43 million in an oversubscribed Series A round. Together with the $32 million raised in pre-seed and seed rounds, Avail’s total funding now reaches $75 million.
Participating in the Series A round are well-known venture capital firms Founders Fund, DragonFly Capital, Cyber Fund and other well-known VCs including SevenX, Figment, Nomad Capital, LocalGlobe, Altos Ventures, Chapter One, Superscrypt, Foresight Ventures, Mirana Ventures, KR 1, RW 3 Ventures, Alliance Dao, Hashkey, Elixir Capital, Spark Digital Capital and some angel investors.
The Series A funding will further accelerate Avail’s mission to solve scalable data availability, interoperability, and rollup fragmentation problems through a unified layer – a cutting-edge, modular technology stack that combines data availability, aggregation, and shared security to enable modular blockchains to scale and interoperate permissionlessly and securely.
“This Series A funding round marks an important moment for Avail as we work to build the permissionless unified layer for Web3,” said Anurag Arjun, co-founder of Avail. “With this new funding, we are expected to accelerate development, expand our global presence, and continue to address the most critical challenges facing Web3 today, such as blockchain fragmentation, insufficient data availability, and limited scalability. Additionally, it will help foster collaboration with other players across the Web3 ecosystem, which is key to Avail’s success.”
Avail DA provides developers with decentralized infrastructure that enables them to quickly build and scale modern blockchain applications. The biggest value proposition of launching a new rollup instead of creating a separate L1 is the ability to inherit security from the base layer. In order for Avail to become a unified layer for Web3, it needs to be extremely secure. To achieve this, Avail will expand re-collateralization to include multiple assets such as BTC and ETH, providing ample security for thousands of rollups.
"Avail is making data availability - a historically costly problem for blockchain - cheaper and more efficient through their innovative, custom approach. Their DA solution, coupled with the Nexus interoperability layer and Fusion security layer, makes it very easy and seamless for teams to leverage Avail's technology stack to create new protocols (across all cryptocurrency categories). Not only is their solution extremely scalable and economical, but it is also a very strong choice in terms of security. We are proud to support Anurag, Prabal, and the talented team at Avail as they build this critical piece of crypto infrastructure," said Joey Krug, Partner at Founders Fund.
Next on the Avail unified layer roadmap is Avail Nexus, which solves interoperability across rollups. This unified layer is a zero-knowledge coordination rollup built on top of Avail DA, which acts as a validation hub that unifies multiple rollups and solves blockchain fragmentation issues such as isolated liquidity. Avail Nexus creates a seamless user experience by abstracting chains, no matter how many rollups they interact with or which ecosystem they are built on.
“The potential of Web3 is enormous, and Avail is at the forefront of making this new paradigm accessible and useful across a wide range of applications,” said Haseeb Qureshi, Managing Partner at Dragonfly. “We are excited to support Avail as they continue to push the boundaries of possibility in this space.”
The Series A funding will also support the development of Fusion Security, a novel approach to ensuring unified and shared security within the Avail ecosystem. By leveraging native assets from established ecosystems and new rollup tokens, Fusion Security aims to provide strong cryptoeconomic guarantees, strengthening Avail’s capabilities as a unifying layer for Web3.
Avail recently passed a major milestone in its incentivized testnet “Clash of Nodes,” peaking at 310 validators, nearly 110,000 accounts created, and 116 million transactions processed in total — ahead of the upcoming mainnet launch in a few weeks.
“Avail combines interesting technology, using mature infrastructure like Substrate, with state-of-the-art data availability sampling and zero-knowledge proof schemes,” said Walt Smith, an investor at Cyber Fund. “We believe it has the potential to be a promising technology across different blockchain technologies.”
By providing a scalable data availability layer, a unified cross-chain coordination center, and a highly shared native token economic security, Avail is helping to enable a connected, user-friendly, decentralized future.

About Avail:
Avail, led by former Polygon co-founder Anurag Arjun, is committed to building a unified layer to solve the problem of large-scale rollup fragmentation. Avail fundamentally solves the blockchain scalability problem, leveraging Avail DA, a foundational data availability layer, to implement the same technologies planned for Ethereum's danksharding roadmap, including KZG Commitments and Data Availability Sampling (DAS). Avail Nexus solves the growing fragmentation problem by performing proof aggregation on the Avail scalable DA layer, providing permissionless interoperability. Subsequently, Avail's security is strengthened through multi-asset staking with Avail Fusion.
