Avail has launched its Nexus Mainnet, introducing a cross-chain network designed to unify liquidity and user flows across major blockchain ecosystems. The upgrade marks a significant moment for modular blockchain infrastructure as developers push toward a more coordinated and less fragmented onchain environment.
The network supports Ethereum, TRON, Polygon, Base, Arbitrum, Optimism, HyperEVM, BNB Chain, Scroll, Monad, Kaia, and others. Support for Solana is planned. Avail positions Nexus as the first coordinated, liquidity-aware cross-chain system in production.
Co-founder Anurag Arjun said fragmented architectures and isolated ecosystems have constrained Web3 users for years. He argued that blockchains must operate as components of a unified, verifiable system rather than independent networks exchanging fragile messages.
A Shift from Bridging to Shared Liquidity
Cross-chain activity has historically relied on bridges that concentrated risk and fragmented liquidity across networks. Avail Nexus seeks to replace that model with intent-based execution supported by multi-chain liquidity sources and predictable settlement guarantees.
The network’s intent–solver system lets users specify desired outcomes, while Nexus determines the optimal execution path. Multi-source liquidity allows single transactions to draw funds from several chains simultaneously. Exact-Out execution helps guarantee predictable results regardless of where the liquidity resides.
Avail plans to extend Nexus with unified verification powered by Avail DA. The system will anchor cross-chain execution to verifiable data availability, forming a shared liquidity and shared execution layer across connected networks.
What would be implications for Users
Nexus aims to provide users with a single transactional environment spanning multiple chains. The system removes bridging workflows, reduces gas-token friction, and aggregates liquidity across networks for better execution quality.
Execution is coordinated across chains, offering faster settlement and more predictable outcomes. Users gain access to applications regardless of their deployment chain, shifting cross-chain interactions toward a more integrated experience.
Arjun said the shift represents meaningful progress toward Web3 usability that supports next-generation consumer-facing applications.
What would be Implications for Developers
Developers can connect to Nexus through SDKs, APIs, or lightweight “Elements” that abstract away multi-chain routing logic. A single integration can expose applications to a multichain user base without requiring bridge management or complex routing infrastructure.
Nexus introduces unified collateral pools that update across networks in real time. Developers can build intent-based trading systems and coordinated multi-chain strategies without managing the underlying liquidity infrastructure.
Avail’s data availability platform underpins the system. The team’s “Infinity Blocks” roadmap targets 10-GB block capacity, enabling scalable appchain deployments that remain connected to the wider multichain environment. The AVAIL token acts as the economic and coordination asset for the network.
Co-founder Prabal Banerjee said cross-chain execution at scale has historically posed major engineering challenges. He noted that Nexus automates routing, verification, and liquidity coordination, allowing developers to focus on core application logic.
A Growing Ecosystem of Integrations
Avail Nexus launches with integrations live or in progress across DeFi, infrastructure, SocialFi, AI, and cross-chain tooling. Early partners include Lens Protocol, Sophon, TRON, Space & Time, Lumia, Validium Network, Vanna Finance, Mace, Clober, Station X, Nexus AI, Bitte.ai, Neova, Gummee, and Symbiotic.
Many integrations target use cases that previously faced fragmentation issues, including unified collateral management, intent-based trading across multiple venues, and coordinated cross-chain data-driven automation. Others focus on multi-chain liquidity aggregation that lets assets on one chain power opportunities on another.
With Nexus Mainnet now active, developers can integrate through the Nexus SDK. Avail says the first wave of “Liquid Apps”—applications designed to demonstrate unified liquidity—will roll out soon. Additional chain integrations and ecosystem expansions will be added progressively.
Avail was founded by early members of Polygon and is backed by Founders Fund, Dragonfly, Cyber Fund, and other investors.
