Avail

Avail is a modular blockchain infrastructure platform built to address the data availability, interoperability, and security challenges that constrain scalable Web3 applications. Originally incubated within Polygon, Avail became an independent project in 2023 under co-founders Anurag Arjun and Prabal Banerjee, and launched its data availability mainnet in 2024. The project's core thesis is that the blockchain stack should be decomposed into specialized, interoperable layers — with Avail providing the foundational infrastructure across all three critical dimensions.

Three-Layer Architecture

Avail's full-stack vision centers on three interconnected products:

Avail DA is the project's data availability layer and its most mature component. It provides cryptographic guarantees that transaction data is published and retrievable — a property distinct from mere storage. Avail DA employs KZG polynomial commitments combined with erasure coding and Data Availability Sampling (DAS) to let light clients probabilistically verify block availability without downloading entire datasets. This means resource-constrained devices can independently confirm that rollup data is available without trusting third parties.

The layer achieves 250-millisecond pre-confirmations with full finality in approximately 20 seconds. Current production throughput is 4MB per block, with benchmarks demonstrating scalability to 128MB per block without sacrificing network liveness. Rollups posting data to Avail DA report cost reductions of 70–90% compared to posting directly to Ethereum L1. The layer is chain-agnostic and integrates with major rollup frameworks including Arbitrum Orbit, OP Stack, Polygon CDK, zkSync, Sovereign SDK, Rollkit, and Dymension. Live production users include Rooch, Lens, Sophon, and Odysphere.

Avail Nexus is Avail's cross-chain interoperability layer, built as a custom ZK rollup that aggregates and verifies validity proofs from multiple rollups into a single consolidated proof. Rather than requiring direct connections between every pair of chains, Nexus functions as a coordination hub: applications express user intents, and solvers fulfill them by routing liquidity across connected chains in a single flow. The Nexus mainnet launched in late 2025 and supports over 13 major chains with more than 25 integrating applications. Key Nexus products include FastBridge (consolidating multiple cross-chain transfers into a single transaction), Deposits (combining balances across tokens and chains for unified account funding), and Widgets (embeddable cross-chain components enabling any app to operate across chains with a single integration).

Avail Fusion is the project's planned security layer, currently in prototype. Fusion introduces an additive crypto-economic security model that allows external assets — including Bitcoin, Ether, and SOL — to contribute to Avail's consensus security. Rather than relying solely on staked AVAIL tokens, Fusion enables holders of established assets to restake them toward Avail's security budget, broadening the network's economic backing without requiring those assets to migrate.

Token and Network Metrics

The native AVAIL token launched alongside the DA mainnet. It serves as the economic backbone across all three layers: paying data availability fees, securing the network through staking, and governing the ecosystem. Total supply is capped at 10 billion tokens; 600 million were distributed via airdrop at launch. As of mid-2026, the network operates with 80 active validators and 4.5 billion AVAIL staked.

Team and Funding

The project is led by Anurag Arjun, a co-founder of Polygon, and Prabal Banerjee. Avail has raised $75 million in total across two rounds: a $27 million seed round and a $43 million Series A announced in June 2024. The Series A was co-led by Peter Thiel's Founders Fund, Dragonfly Capital, and Cyber Fund. Additional investors include SevenX Ventures, Figment Capital, Nomad Capital, Chapter One, Foresight Ventures, Mirana Ventures, KR1, Alliance, and HashKey Capital.

Ecosystem Reach

Avail claims over 70 partnerships spanning application-specific blockchains, DeFi protocols, and Web3 gaming projects. Five major Layer 2 networks — Arbitrum, Optimism, Polygon, StarkWare, and zkSync — have committed to integration. Current live Nexus-powered applications include QuickSwap (with CLOB execution via Avail Atomic), Clober, Bean Exchange, and KalqiX, which launched on mainnet using Avail DA. ShieldTX, a private perpetual trading platform on Hyperliquid, also runs on Avail infrastructure.

Competitive Positioning

Avail competes primarily with Celestia and EigenDA in the data availability layer market. Its principal differentiators are chain-neutrality (no structural preference for Ethereum or any other settlement environment) and the integrated full-stack offering combining DA, interoperability, and shared security under one token and governance model. Nexus's ZK proof aggregation approach distinguishes it from bridge-centric interoperability solutions. The main competitive pressure comes from Celestia's higher raw throughput and EigenDA's deep integration with Ethereum restaking infrastructure.

Audit and Security Status

Avail's cryptographic approach — combining KZG commitments with DAS — is grounded in established academic research. The project has not publicized specific third-party audit reports in materials reviewed; developers and integrators should consult the official documentation and GitHub repository for current audit disclosures before deploying production systems reliant on Avail DA guarantees.
