Avail Nexus Mainnet launched on November 28, 2025 as Avail's cross-chain execution layer. It's designed to unify liquidity and user flows across a long list of major networks. That includes Ethereum, TRON, Polygon, Base, Arbitrum, Optimism, BNB Chain, Scroll, Monad, and Kaia, with Solana support listed as coming soon.
What Problem Avail Nexus Mainnet Solves
Web3 liquidity has historically been fragmented by chain. An asset sitting on Arbitrum isn't directly usable on Base or Polygon without bridging, wrapping, or manually managing gas tokens on each network. Avail describes Nexus Mainnet as the first time Web3 gains access to a coordinated, liquidity-aware crosschain network. Liquidity and execution become network-wide resources, rather than belonging to individual blockchain environments.
How Builders Interact With Nexus
Developers integrate through the Nexus SDK. It's designed to let application logic stay separate from the underlying complexity of routing liquidity, verifying transactions, and executing actions across multiple chains. According to Prabal Banerjee, Co-Founder of Avail, the goal is for builders to focus purely on their application while the infrastructure layer manages liquidity routing and cross-chain execution automatically.
New Use Cases Nexus Mainnet Enables
The launch unlocks several use cases that were previously fragmented or impossible across separate chains. That includes unified collateral management for DeFi protocols, intent-based trading with execution routed across multiple liquidity venues, coordination layers for cross-chain data-driven actions, and multi-chain liquidity aggregation. Assets on one network can power opportunities on another, without a user manually bridging funds first.
Early Ecosystem Partners
At launch, Avail listed a broad set of ecosystem partners building on Nexus. That includes Lens Protocol, Sophon, TRON, Space & Time, Lumia, Validium Network, Vanna Finance, Mace, Clober, Station X, Nexus AI, Bitte.ai, Neova, and Symbiotic, spanning DeFi, social protocols, and data infrastructure projects.
What's Coming Next: Unified Verification and Infinity Blocks
Avail has flagged unified verification as a near-term addition, powered by Avail DA. It's intended to back cross-chain actions with verifiable data, rather than simple message-passing between chains. Longer-term, Avail's Infinity Blocks roadmap targets 10-GB block capacity on Avail DA. That aims to let builders launch independent appchains with high throughput, while remaining connected to the broader Nexus ecosystem. The AVAIL token functions as the coordination asset underpinning this unified onchain structure.
Nexus Mainnet's focus on unifying fragmented liquidity sits alongside other 2026 infrastructure launches like Hotstuff Labs' validator-based fiat routing layer. Both aim to reduce friction between separate financial systems, though through different architectural approaches.
Glossary
- Crosschain execution: The ability to route and execute transactions across multiple blockchain networks without requiring manual bridging by the user.
- Modular blockchain: A network architecture that separates functions like execution, settlement, and data availability into distinct layers rather than handling everything on one chain.
- Data availability (DA): The guarantee that transaction data is published and accessible, allowing anyone to verify a blockchain's state.
- Nexus SDK: The developer toolkit used to integrate applications with Avail's cross-chain liquidity infrastructure.
