Company profile
researched Aug 2026Avail is a blockchain infrastructure company building what it calls a "unification layer" for Web3, composed of three modules. Avail DA is a purpose-built data availability (DA) base layer for rollups, L2s and app-specific chains; Avail Nexus is a zero-knowledge coordination and verification hub that aggregates proofs and enables permissionless inter-rollup messaging using Avail DA as the root of trust; and Avail Fusion is a shared security layer based on multi-asset staking, allowing assets such as BTC, ETH and rollup tokens to be staked alongside Avail's native token.
The project's stated aim is to address three linked problems created by the proliferation of rollups: scalability (insufficient DA blobspace), fragmentation and interoperability across ecosystems, and crypto-economic security. Developers can build custom chains on any technology stack while inheriting Avail DA features with a small code integration, and users are intended to experience cross-chain ("bridgeless") transactions with the complexity of asset movement handled by Nexus. The company describes its approach as allowing chains to be set up without the burden of assembling token economics or validator sets.
Founding story
Co-founder Anurag Arjun has described his entry into blockchain as beginning with the book "Mastering Bitcoin" and an early recognition of blockchain scalability limits. While working at Polygon he concluded that rollups could scale Ethereum but still lacked adequate data availability solutions, which led to work on a purpose-built DA layer. Avail began as an initiative inside Polygon in 2020 and was later spun out as an independent entity led by former Polygon founder Anurag Arjun and research lead Prabal Banerjee.
Business model
Avail operates as a blockchain protocol company providing base-layer data availability, interoperability coordination and shared security infrastructure to rollup and application-chain developers, funded to date by venture capital and associated with a native token used for staking within its Fusion shared-security model.
Traction
During its incentivized testnet, Avail reported processing over 118 million transactions and facilitating more than 140GB of data submissions, described as close to the total data submissions of all L2s in 2023; a separate interview cited over 300 validators and over 115 million transactions processed. Total disclosed funding stands at $75M across pre-seed, seed and Series A rounds from investors including Founders Fund, Dragonfly and Cyber Fund.
Latest developments
With the $43M Series A complete and the Unification Drop announced, Avail said its next major milestone was the mainnet launch of Avail DA, described as launching "in the coming weeks" at the time of the announcement. Proceeds from the $27M seed round were earmarked to expand beyond core DA services to build out Nexus and Fusion as part of a three-phase roadmap.

Market position
Avail is positioned in the modular blockchain / data availability segment, which gained attention following the launch of comparable projects such as Celestia that target the scalability limits of chains like Ethereum and Solana. Avail differentiates by pairing DA with interoperability (Nexus) and multi-asset shared security (Fusion) rather than offering DA alone.
Avail states that its DA layer is built from first principles on validity proofs and data availability sampling, arguing that interoperability solutions built atop a non-scalable base layer eventually hit scaling constraints. Its combined stack of DA, a ZK coordination hub and multi-asset staking-based shared security is presented as a broader offering than DA-only alternatives.
Technology
Avail DA implements data availability sampling (DAS) over erasure-coded data together with validity proofs using KZG commitments, the same class of technology earmarked in Ethereum's danksharding roadmap. This allows light clients on consumer-grade hardware to verify data availability guarantees without relying on a full node, reportedly in under a minute. Avail Nexus is a custom zero-knowledge coordination layer performing proof aggregation and permissionless inter-rollup messaging with Avail DA as the root of trust. Avail Fusion extends restaking to multiple assets (for example ETH and BTC and rollup tokens) to provide additive crypto-economic security.
Go-to-market
Avail targets blockchain developers directly, offering integration of Avail DA into custom chains with minimal code, and has used an incentivized testnet (Clash of Nodes) plus a token distribution event (the Unification Drop) to attract validators, light client operators and ecosystem participants. Community channels cited include X, Discord and Telegram.
Developers and teams building rollups, Ethereum L2s, sovereign rollups and application-specific blockchains, along with validators and light-client operators participating in the network.
History
Avail started as a project within Polygon in 2020, where the team had been working on data availability technology. It was spun off into a full-fledged independent entity (reported by YourStory in February 2024 as having spun off "last year"), led by co-founders Anurag Arjun and Prabal Banerjee. The company raised $5M in pre-seed funding, a $27M seed round and a $43M Series A, bringing total disclosed funding to $75M. Ahead of mainnet, Avail ran the "Clash of Nodes" incentivized testnet, which grew to over 300 validators; the testnet processed over 118 million transactions and more than 140GB of data submissions. With the Series A closed and its "Unification Drop" announced, the company's stated next milestone was launching Avail DA on mainnet.
Risks & controversies
Co-founder Anurag Arjun has noted that fundraising during a bear market was a challenge, with investors more cautious and project fundamentals scrutinized more closely. The company also operates in a competitive data availability market alongside projects such as Celestia. Note: several similarly named entities exist, including Avail Infrastructure Solutions, an unrelated industrial electrical products joint venture.
