Nexora Swap

Nexora Swap is a multi-router DEX interface for fast, cleaner token swaps across major EVM chains and Solana.

Live app: https://nexoraswap.online

Overview

Nexora Swap is built for two core flows:

• Same-chain EVM swaps: Auto compares available routes between 1inch Direct and LI.FI Smart Routing.
• Solana and cross-chain swaps: Uses LI.FI for Solana, EVM-to-Solana, Solana-to-EVM, and cross-chain execution, with gas.zip available as a dedicated cross-chain route option in the UI.

The app focuses on keeping swap execution more transparent by showing route selection, minimum received, wallet balances, USD estimates, and bridge-related fee details directly in the interface.

Features

• Multi-router swap experience with Auto, LI.FI Smart Routing, 1inch Direct, and gas.zip route options
• Same-chain route comparison in Auto (best) mode
• Cross-chain swaps across supported EVM networks and Solana routes supported by LI.FI
• Solana token lists, token metadata, USD prices, balances, and LI.FI transaction payload support
• Solana wallet support via Wallet Standard and injected wallets such as Phantom, MetaMask, Bitget, Solflare, and Backpack
• EVM wallets via MetaMask/WalletConnect, with Solana and EVM wallets handled separately in the UI
• Token selector and chain selector for both swap sides
• Wallet token balances in the token picker, plus DexScreener USD estimates for selected swap tokens
• Custom token import by contract address
• Minimum received estimate shown before swap confirmation
• Bridge fee estimate and tx value visibility for cross-chain swaps
• Exact ERC-20 approvals instead of unlimited approvals
• Human-readable error states for common quote and liquidity issues
• Liquidity source breakdown in the advanced route view

Supported chains

• Ethereum
• Polygon
• Arbitrum
• Optimism
• Base
• BNB Chain
• Avalanche
• Solana

Routing behavior

Same-chain

• Auto (best) compares 1inch Direct and LI.FI Smart Routing for same-chain EVM swaps and picks the better available quote.
• You can manually force 1inch Direct or LI.FI Smart Routing from the route selector on EVM chains.
• Solana same-chain swaps use LI.FI Smart Routing because 1inch Direct is EVM-only in this app flow.

Cross-chain

• Cross-chain swaps are handled through LI.FI in the current app flow, including Solana routes when LI.FI supports the pair.
• gas.zip is available as a selectable cross-chain route option.
• The UI surfaces estimated bridge fee information and the native token value the wallet will send for the transaction.

Getting started

1. Install dependencies

npm install

2. Configure environment variables

Create a .env file in the project root. then fill all env from .env.example.

Wallet setup note

• EVM swaps use MetaMask or any WalletConnect-supported wallet.
• Solana swaps use a Wallet Standard or injected Solana wallet such as Phantom, MetaMask, Bitget, Solflare, or Backpack.
• Cross-chain flows can require both wallet types if the source and destination chains are different families.

3. Run the development server

npm run dev

Open http://localhost:3000 in your browser.

4. Build for production

npm run build
npm run start
