What you can do now
- Move more: The upgrade raises the cap on transaction sizes and values that flow through Nexus. Larger cross-chain transfers including six-figure transfers or more. This means bigger deposits and higher-value swaps, all without hitting limits.
- Build with better tools: The Fastbridge widget and Avail Deposits widget have been refreshed with a cleaner interface and clearer flow states. Whether you're embedding fastbridging for multi-chain asset movement, or a deposit flow for your app's onboarding, the components are now configurable and able to be dropped into the front-end of any app.
- Launch liquid apps: Users move funds, swap tokens, and interact with your app regardless of which chain they're on. They don't have to think about bridging or holding gas on remote chains. It works with perp exchanges, liquidity pools, prediction markets, payments apps and more.
All Nexus integrated apps have now migrated, including Clober, Mace, ShieldTX, Bean Exchange, Fastbridge and more. These are Liquid Apps, immediately available on every major EVM chain, with access to users and liquidity from across the ecosystem.
How it works
Avail Nexus handles the hard parts of going multi-chain, allowing developers to build multi-chain apps in hours instead of weeks.
Here’s what you get.
Intent based routing: A user says what they want and Avail Nexus automatically works out how to get it done, across chains, protocols and liquidity sources. This gives your engineering team and users what they want without the manual overhead of cross-chain management.
Gas abstraction: Users and engineers don’t have to worry about routing through different protocols without the funds necessary to process onchain transactions. Avail Nexus manages gas automatically, making it seamless for both users and development teams to operate.
Unified balance: Users have funds spread across many different chains. With Avail Nexus, a user’s multi-chain balance is unified into a single, spendable balance.
Last-mile delivery: The assets you need in your app land wherever you want, on the right chain, in the right token, ready for executing your smart-contract, deposit flow, trading experience or yield vault.
Higher transaction limits: The Nexus Rising upgrade raises the ceiling on transaction values. For larger transactions, including six-figure transfers or more, Nexus can now access Mayan's liquidity infrastructure to facilitate execution at greater scale. This expands the transaction capacity of the Nexus product suite, enabling support for bridge transactions of up to $10 million in a single transfer.
Architecture
Avail Nexus is now a sovereign rollup on Avail DA. That means the coordination layer runs on the same foundation as the data availability layer.
Why does this matter? Avail is the growth engine for apps to expand beyond one chain. When your app goes multi-chain, Nexus handles the complexity. Routing, bridging, gas abstraction, last-mile delivery, all of it. The coordination layer does the work so your app doesn't have to. Because it runs on Avail DA, it inherits the foundation’s scaling properties and all intent data and cross-chain interactions are available and verifiable on Avail DA. As your app grows the infrastructure that supports multi-chain interoperability grows with it.
The Nexus Rising upgrade represents how we operate at Avail. Continuous improvements towards a clear vision. The original plan was Avail Nexus on Avail DA. We acquired Arcana and immediately shipped Nexus on their tech stack to get to market faster. Now we are delivering on the original promise, not a shift away from the plan but one that maps to an original vision, yet grounded in practical reality. That is Kaizen, and this is how we operate at Avail.
Getting Started
Nexus Rising is now live. Nexus widgets give you the fastest path with a simple UI integration giving you access to a seamless deposit experience and fastbridging for moving assets multi-chain.
With this upgrade, both the Fastbridge widget and the Deposits widget have been refreshed with a cleaner UI, clearer flow states, and improved responsiveness. Whether you're embedding a fastbridge component for multi-chain asset movement or a deposit flow for your app's onboarding, the widgets are production-ready out of the box.
For more customisability, use the Nexus SDK.
Every chain connected. Scaled on Avail DA.
