# Avail > Scale Access to the Onchain Economy Avail is a modular data availability project for blockchains. It helps developers build scalable, interoperable chains by providing data availability infrastructure and cross-chain connectivity. Avail is a project providing modular data availability infrastructure for blockchains. It helps developers build scalable and interoperable chains by offloading data storage and verification away from execution layers. The project serves rollups, app-specific chains, and sovereign networks that need dependable data availability without building this infrastructure themselves. Avail addresses blockchain fragmentation, where applications and liquidity become siloed across many separate chains. Its data availability layer uses cryptographic commitments and sampling techniques so that light clients can verify data availability without downloading entire blocks, allowing blockspace to scale while keeping verification lightweight. A companion interoperability layer lets users and applications move value and messages across multiple networks without manual bridging steps. The core offerings include Avail DA, the data availability layer, and Avail Nexus, which provides unified balances and cross-chain execution for applications. A staking layer reinforces network security through multi-asset participation. Avail is used by rollups, app teams, and decentralized exchanges seeking access to liquidity and users across many blockchain networks, and it operates as an independent, community-oriented project with a remote-first team. - Type: Project - Sector: Infrastructure - Status: Active - Founded: 2023-03-01 - Profile: https://thegrid.id/profiles/avail ## Products - [Avail DA](https://thegrid.id/profiles/avail): Avail DA is a data availability layer that lets blockchains publish transaction data in a way that is provably retrievable and verifiable by anyone. It uses validity proofs, polynomial commitments, and data availability sampling so light clients on resource-constrained devices can confirm data availability without downloading full blocks. The layer is used by rollups and other high-throughput chains to scale blockspace while inheriting cryptographic guarantees for secure settlement. (Data Terminal, Live) - [Avail Nexus](https://thegrid.id/profiles/avail): Avail Nexus is a cross-chain coordination layer that lets applications access users, assets, and liquidity from multiple blockchains without manual bridging. It treats a user's holdings across chains as a single unified balance, using vault contracts to escrow funds and solver-based intent execution to move value between networks. Developers integrate it through a software development kit, prebuilt interface components, or an API to enable deposits, swaps, and agentic payments across chains. The system is used by decentralized exchanges and other applications to onboard users regardless of which chain their assets are held on. (Cross-chain Infrastructure, Live, Main Product) - [Avail Fusion](https://thegrid.id/profiles/avail): Avail Fusion is a multi-token staking infrastructure that allows holders of assets native to other blockchains to help secure the Avail network alongside its own token. It pools staked assets and applies restaking mechanisms to broaden the set of participants contributing to network security. The product is intended for holders of major blockchain assets who want to contribute to cryptoeconomic security without leaving their existing holdings idle. Avail Fusion has been announced but is not yet accessible to users. (Staking & Validation Services, In Development) ## Assets - [Avail (AVAIL)](https://thegrid.id/profiles/avail): AVAIL is the native token of the Avail network. It is used to pay for data availability fees and secure the network through staking. The network allows light clients to independently verify data availability on resource-constrained devices without downloading entire datasets, using data availability sampling to enable rollups and blockchains to offload transaction data storage while maintaining cryptographic proof of availability.
