Avail’s Nexus wants to be Web3’s execution spine, not just another bridge

Christina Comben 1 minute ago Avail’s Nexus wants to be Web3’s execution spine, not just another bridge Nexus wants to be more than just another bridge, turning crosschain chaos into one unified balance so users can move assets seamlessly between blockchains. Listen 0:00 12 News COINTELEGRAPH IN YOUR SOCIAL FEED The Avail Nexus mainnet launched this week, promising to radically rewire how assets move between blockchains. Instead of another bridging tool, Nexus wants to make multichain execution as seamless as tapping a button, sidestepping years of awkward crypto UX and operational headaches. Nexus wants to fix the crosschain user experience Nexus sets out to solve a nagging question in Web3 : why do users with onchain assets still get stuck, forced to bridge tokens, swap for gas, and bounce between apps just to use their funds? Avail Nexus mainnet is live across 13 ecosystems Prabal Banerjee, Avail co-founder, told Cointelegraph, “Users should be less burdened by chains and underlying infra. UX should default to abstraction (unified balances, one-click flows), but critical security/contextual signals must remain visible and explainable, because security and choice matter.” He sees the problem not as a lack of routes, but the absence of a native coordination layer, one that lives inside apps and quietly harmonizes multichain flows. Today’s bridge and decentralized exchange (DEX) aggregators promise the best route across chains, but they are still stitching together a sequence of hops: bridge here, swap there, bridge back. Under the hood, that means imperative multi‑step plans executed across autonomous systems, with weak guarantees if one leg fails mid‑flight. Banerjee argues that this model has hit its limits: liquidity is fragmented, UX is brittle, and users are forced to think like infra engineers instead of just using apps. Nexus tries to flip that stack. Instead of asking users to pick a route, it accepts signed “intents” (end‑state goals plus constraints) and outsources the “how” to a solver network that can source liquidity across multiple chains and return an “exact‑out” execution plan. In other words, the user says what they want, not how to get there.

Nexus automates all the complicated bits (gas, approvals, routing, crosschain accounting) so users interact with apps, not chains. The focus is retention, not just cost. Banerjee describes the current problem as “a fragmented experience where users need to know and understand chains on which apps are built rather than just using the apps.” Nexus wires decentralized applications (DApps) to become environments where users never leave, with one pool of value displayed as a single number in-app. Trust, risks, and the intent model This new model pivots the trust surface away from bridges and toward solvers. Intents mean new MEV and routing challenges, while solvers and flows become critical infrastructure. To minimize risk, funds are locked in onchain vault contracts and only released when solvers fulfill the exact terms in a set window. Failed routes trigger an automatic revert, restoring user funds. Positioning in the modular stack Other modular and shared-sequencer designs require core changes at the blockchain protocol level, making them a tough practical fit for big production chains. “Many shared sequencer and shared bridge efforts need chain-level modifications,” Banerjee explains, “which are always tricky to do, especially with large production chains. Hence, their adoption has been much slower than anticipated.” Avail’s approach is strictly application-layer: software development kits, APIs, and modular “elements” that can be dropped into live DApps and rollups, with no need to touch underlying chain consensus or protocol wiring, and foundationally supported by Avail’s data availability verifiability. Most competitors, in Banerjee’s view, “try to solve crosschain UX at the coordination layer or at the chain level.” In contrast, Nexus collapses UX into a unified flow: one balance, one interface, one operating universe. Early signs of approval have come from other modular ecosystem leaders. Monad’s mainnet launch included a call-out to Nexus, hinting that some L1s see this kind of execution-layer abstraction as strategic infra rather than a nice‑to‑have integration.

For Avail, the ambition is clear: a mulitchain internet that feels like one user-centric network running beneath the surface (and to do it without quietly becoming the new middleman along the way).
