Avail, a modular blockchain infrastructure provider building the foundations for the next generation of applications and appchains, today announced the launch of Avail Nexus Mainnet, its breakthrough crosschain solution that unifies liquidity and user flows across major ecosystems, including Ethereum, TRON, Polygon, Base, Arbitrum, Optimism, HyperEVM, BNB, Scroll, Monad, Kaia, Solana (coming soon), and others.
The launch marks the first time Web3 has access to a coordinated, liquidity-aware cross-chain network, bringing Avail’s long-stated vision of a connected onchain world into production. For users and developers, this unlocks something the industry has attempted for years but never achieved at scale: a single operational universe where applications and assets work across chains without fragmentation, friction, or duplicated effort.
A Major Shift in How the Onchain Economy Works
“The current blockchain fragmentation and siloed interactions across ecosystems have limited both the builder and user experience,” said Anurag Arjun, Co-Founder of Avail.
“At Avail, we are transforming how blockchains interact. They can no longer be separate networks passing messages to each other; rather should function as integral parts of a unified, verifiable system where assets, users, and intended actions move freely. This fundamental shift, in how apps scale and modular stacks connect to the broader multichain world, is the future.”
Until now, crosschain has meant risky bridges, limited access, and fragmented liquidity across chains. Avail Nexus takes a different approach:
- An Intent–solver architecture allows users to express what they want to do; Avail Nexus determines how to do it, automatically finding the optimal route, liquidity source, and execution path.
- Multi-source liquidity allows a single transaction to draw funds from multiple chains simultaneously.
- Exact-Out execution ensures predictable outcomes regardless of where liquidity lives.
- Unified verification,coming soon, powered by Avail DA, for cross-chain actions backed by verifiable data.
This moves the blockchain environment from its current “moving messages between chains” to shared execution and shared liquidity; a fundamental upgrade in how the onchain economy functions.
What Changes for Users with Avail Nexus
Users gain for the first time
- A single experience across ecosystems (no bridging UX, no gas token hassles).
- Better prices and deeper liquidity through cross-chain aggregation.
- Faster, predictable execution coordinated across chains.
- Access to apps regardless of where they are deployed.
“This is a usability shift toward making Web3 for the real users of the next generation of consumer apps”, highlights Anurag Arjun, Co-founder of Avail.
What Changes for Developers
Developers can integrate Nexus through SDKs, APIs, or lightweight Elements, enabling:
- One-time integration to unlock a multichain userbase
- Unified collateral pools that update across chains in real time
- Intent-based trading and strategy execution
- Cross-chain actions without managing bridges, routers, or complex infra.
This reduces the cost, time, and complexity of building multichain applications by an order of magnitude. And bolstered by Avail’s proven data availability expertise, the overall operational and functional experience remains robust, verifiable, and scalable. Avail DA, with its industry-defining Infinity Blocks roadmap targeting 10-GB block capacity, is soon set to enable builders to spin up independent appchains with massive throughput and finality while remaining connected to the broader ecosystem with verifiable cross-chain data. The $AVAIL token serves as the coordination asset and economic backbone for this unified onchain world.
“For builders, the complexity of cross-chain execution at scale has always been a major challenge. With Avail, that complexity disappears. Builders can focus on application logic while the infrastructure handles liquidity routing, verification, and execution under the hood, enabling truly composable and highly scalable apps and appchains. The overall result will be a smoother, more capital-efficient user experience where liquidity and execution no longer belong to individual blockchain environments; rather, they become network-wide resources”, explains Prabal Banerjee, Co-Founder of Avail.
A Rapidly Growing Ecosystem
Avail Nexus is launching with integrations live or underway across DeFi, infrastructure, SocialFi, AI, and cross-chain tooling. Ecosystem partners and projects, including Lens Protocol, Sophon, TRON, Space & Time, Lumia, Validium Network, Vanna Finance, Mace, Clober, Station X, Nexus AI, Bitte.ai, Neova, Gummee, Symbiotic, and more, are enabling powerful new use cases. Many integrations unlock use cases that were previously impossible or highly fragmented across chains, including unified collateral management for DeFi protocols, intent-based trading with execution across multiple liquidity venues, intelligent coordination layers for cross-chain data-driven actions, and multi-chain liquidity aggregation that allows assets on one chain to power opportunities on another.
Availability and Next Steps
With Nexus Mainnet now live:
- Developers can integrate through the Nexus SDK.
- Users will soon explore the first wave of Liquid Apps, applications going live on Avail Nexus, showcasing unified liquidity and opportunities at scale.
- Additional chain integrations and ecosystem expansions will roll out progressively.
