Blockchains need to guarantee that transaction data is published and retrievable-not just stored, but provably available to anyone who needs to verify it. That's data availability.
From DeFi to Gaming to RWAs, Avail delivers verifiable data availability that lets every chain launch faster, scale further, and reach more users. Build on a trusted foundation for the next generation of blockchain networks.
Avail DA empowers developers to focus on product experience, not infrastructure. With predictable performance and instant data verification, your apps can deliver faster finality, smoother onboarding, and uninterrupted user flows - even under heavy load.
Whether you're building DeFi platforms, gaming worlds, or real-world asset markets, Avail's DA layer ensures your users get the speed, security, and reliability they expect from modern on-chain applications.
Avail DA guarantees data integrity through a combination of validity proofs, KZG polynomial commitments, and data availability sampling (DAS). Every block posted to Avail can be independently verified by light clients, even on resource-constrained devices, without needing to download the entire dataset.
This means applications built on Avail inherit cryptographic proof of data availability, enabling trustless interoperability and secure rollup settlement across L2s and L3s.
Blazingly fast, verifiable, and privacy-preserving - Avail DA sets the new standard for blockchain scalability.
250ms preconfirmations with 20s DA finality, fastest in the industry.
No surprises. Pre-purchase data credits in your own ERC-20 token.
Verify data is available on any device with light clients, settle L2s and L3s on-chain using our ZK bridge.
Encrypted and verifiable DA for privacy-preserving applications.

Avail DA powers every kind of chain, from high-performance rollups to privacy-preserving apps, giving you verifiable data availability at any scale.
Scale Validiums, Optimiums, or Sovereign Rollups without compromising verifiability. Avail DA combines KZG commitments, DAS, and a ZK bridge that lets rollups and light clients prove data inclusion and settle securely on-chain.
Encrypted and verifiable DA for privacy-preserving applications.
Give users lightning-fast responsiveness with 250ms preconfirmations and 20s finality. Ideal for gaming, social, and high-frequency apps where speed and reliability define the experience.
Keep data private while staying verifiable with encrypted DA. Confidential state updates remain provably available, enabling secure, privacy-preserving apps across DeFi, RWAs, and institutional use cases.
"Data availability is the foundation everything else depends on. If you can't trust that data exists, nothing else matters. Avail DA makes that trust verifiable."
