#What is Nexus Elements?

Nexus Elements is a specialized, open-source React component library from the Avail project, designed for blockchain developers building cross-chain applications that leverage Avail Nexus—a meta-interoperability protocol unifying liquidity and assets across EVM chains without manual bridging or chain switching. Targeted at Web3 frontend teams and full-stack devs working on DeFi, bridges, wallets, or modular rollups, it delivers plug-and-play components built on @avail-project/nexus-core, integrating shadcn/ui primitives with NexusProvider for instant cross-chain functionality like unified balance views and fast token transfers. Ideal for Next.js or Vite projects needing to abstract chain complexity, it empowers you to ship user-friendly dApps faster by handling approvals, executions, and state under the hood while giving full customization via Tailwind CSS and TypeScript.

#Features ⚡

• Shadcn CLI Integration: Add components directly to your codebase with commands like npx shadcn@latest add.

• NexusProvider Wrapper: One-time app wrap initializes the SDK for wallet connections and cross-chain ops.

• Cross-Chain Primitives: Built-in support for unified balances, bridging, deposits with allowance handling, and custom executions.

• Wagmi & Viem Compatible: Seamless wallet integration via ConnectKit, RainbowKit, or any EIP-1193 provider.

• Customizable & Themed: Tailwind-driven styling with dark/light mode and easy overrides.

• TypeScript-First: Robust types from nexus-core for safe multi-chain development.

#Pros ✅

• Accelerates Web3 UI development by providing working cross-chain components out of the box.

• Eliminates boilerplate for bridging, balances, and approvals—focus on your app logic.

• Full code ownership and extensibility, just like shadcn/ui, with no vendor lock-in.

• Backed by Avail's active ecosystem for long-term updates and EVM scalability.

#Cons ⚠️

• Focused on Avail Nexus features; may require custom extensions for non-EVM or highly specialized chains.

• Assumes shadcn/ui and Tailwind setup—learning curve if starting fresh.

• Component library is growing; currently specialized rather than exhaustive for general UI needs.

#Included Components - Templates

• Unified Balance: Displays aggregated token balances across supported chains.

• Fast Bridge: Quick token bridging interface with recipient and amount handling.

• Deposit: Modal or embedded flow for depositing tokens with optional protocol executions (e.g., supply to Aave).

• Header & Layout Primitives: Chain-aware headers and containers for dApp scaffolding.

• Additional Utilities: Allowance handlers, transaction builders, and SDK hooks integrated into UI.

• Template Repos: Ready-to-clone Next.js starters with pre-configured NexusProvider and examples.

#Pricing 💸

Nexus Elements is completely free and open-source, with all components available under permissive licensing for personal and commercial use. No tiers, subscriptions, or restrictions—provided as a public good by the Avail project to boost adoption of their Nexus interoperability layer.
