Interop & Scalability - Building What Applications Need: Avail’s 2025 Recap

Key Highlights

  • Avail Nexus Mainnet launched in November 2025, enabling intent-driven execution across 13+ major chains, with 25+ applications already live or integrating.
  • Avail DA shipped major performance upgrades, including Turbo mode with 250ms pre-confirmations, encrypted data availability for privacy-preserving use cases, and a clear roadmap toward multi-gigabyte (10GB+) blocks.
  • Avail acquired Arcana, bringing in deep expertise in chain abstraction, user wallets, and a seamless multichain UX, and accelerating Avail’s ability to deliver seamless, cross-chain asset movements for app developers in 2026.

Scaling Access To The Onchain Economy

Avail was formed around a simple belief: blockchains should be accessible and usable for real applications, not just for those willing to manage complex user flows and limited throughput. 

In 2025, we stayed focused on removing the constraints that make onchain products slow, fragile, or hard to scale. That meant continuing to push data availability forward: improving speed, privacy, and scale so applications can operate under unseen loads. It also meant addressing a growing reality: applications no longer live on a single chain. Users, liquidity, and state are spread across ecosystems, while developers are left stitching together fragile cross-chain workflows.

That’s why 2025 also marked the mainnet launch of Avail Nexus, a coordination layer built to help applications operate across chains as a single system. Together, these efforts reflect a single direction: scaling access to the onchain economy by giving developers infrastructure that works at scale.

What follows is a look at what shipped in 2025, how builders are using it today, and what this unlocks for 2026 and beyond.

Shipping the Foundations: Data Availability at Scale

In 2025, Avail DA crossed a decisive threshold.

Throughout the year, Avail delivered a sequence of upgrades that cemented Avail’s position as the most advanced data availability solution in the market. These were not isolated improvements but coordinated releases aimed at making Avail DA even more scalable, fast, and secure for privacy-preserving use cases.

By year-end, Avail DA has introduced:

  • 250 ms pre-confirmations, giving applications on Avail DA an instantaneous, real-time UX.
  • Reduced the DA finality time from 40 sec to 20 sec (the fastest in the industry).
  • Introduced an encrypted data availability upgrade to support privacy-sensitive rollups and applications.
  • A clear roadmap toward multi-gigabyte (10GB+) blocks removing practical ceilings on throughput.

Avail Nexus: Multi-Chain Coordination

Even with sufficient throughput and fast verification, web3 applications remained fragmented across blockchain environments. Legacy blockchain infrastructure pushes the burden of scaling blockchains onto developers and end-users, resulting in complicated user journeys and fragmentation that developers are forced to navigate today.

In 2025, Avail addressed this directly with the mainnet release of Avail Nexus.

Nexus is a coordination layer designed for multi-chain applications that seamlessly connects users, assets, and apps across chains.

Over the course of the year, Nexus enabled:

  • Intent-driven execution, allowing users to express outcomes rather than manually orchestrating cross-chain steps like manual bridging and navigating native gas fees.
  • The first Liquid Apps, a new class of app that breaks free from the constraints of single-chain apps, enabling users and liquidity to flow in from multiple chains at once.
  • Nexus Elements & Nexus SDK, simple tools for developers to enable unified cross-chain application flows.

Ecosystem Momentum: Adoption, Integrations, Apps

Throughout 2025, Avail saw growing adoption across rollups, app chains, and application teams building on top of DA and Nexus. Integrations, partnerships, and deployments reflected a common theme: builders choosing Avail to future-proof app usability and performance.

  • Arcana joined Avail: Avail acquired Arcana, bringing in a team with deep experience in chain abstraction. This strengthened both the Nexus roadmap and Avail’s ability to deliver seamless multichain user experiences while accelerating product velocity across the Avail stack.
  • Nexus expanded across 13+ major chains: Avail Nexus went live across leading ecosystems, including Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Scroll, Monad, HyperEVM, Kaia, TRON, and others, giving applications access to users and liquidity across multiple environments without ever leaving the app’s front end.
  • 25+ applications launched or integrated with Nexus: By year-end, more than 25 applications were building on Nexus for coordinated multichain execution. Projects like Clober, Mace, Neverland, and KalqiX used Nexus to unify liquidity, simplify user flows, and express complex cross-chain logic as a single intent.

Looking Ahead

  • Avail’s focus going forward is simple: connect Avail Nexus, the multi-chain coordination layer to the best data availability layer in the industry, providing applications with unbridled throughput and multi-chain coordination from day one.

The infrastructure is live. The ecosystem is growing. The next wave of applications won’t ask whether they should be multichain. They’ll assume it.

If that’s how you’re building, Avail is where it starts.
