# Avail

> Scale Access to the Onchain Economy

Avail helps developers build scalable blockchains by providing data availability infrastructure through modular blockchain architecture.

Avail helps developers build scalable and interoperable blockchains by providing modular data availability infrastructure. Users can access unlimited blockspace, native cross-chain communication, and trust-minimized verification through light clients. Avail reduces blockchain fragmentation by enabling rollups and sovereign chains to offload data storage while maintaining security through KZG commitments and data availability sampling.

## Products

- [Avail DA](https://thegrid.id/profiles/avail): Avail DA provides horizontally scalable data availability using KZG commitments and data availability sampling, enabling rollups to access unlimited blockspace with trust-minimized verification. The system supports parallel execution across multiple VMs while reducing costs compared to Ethereum. Includes Avail Light Client for consumer-grade data availability verification on mobile devices and laptops without full node storage requirements. (Data Terminal, Live)
- [Avail Nexus](https://thegrid.id/profiles/avail): Avail Nexus implements cross-chain interoperability through zero-knowledge proofs and state aggregation, enabling rollups and sovereign chains to communicate without manual bridging. The system provides proof aggregation and maintains trustless interaction between participating blockchains. (Cross-chain Infrastructure, Live, Main Product)
- [Avail Fusion](https://thegrid.id/profiles/avail): Avail Fusion provides multi-token staking infrastructure allowing native assets from Bitcoin, Ethereum, and other blockchains to secure the Avail network alongside AVAIL tokens. The system enhances cryptoeconomic security through token pooling and restaking mechanisms. (Staking Service, 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.
