Nexa Wallet

Nexa Wallet is a next-generation Account Abstraction (AA) smart wallet designed to make crypto management simple, secure, and intuitive. It combines an AI-powered assistant (uAgent via ASI:One), real-time token prices from Pyth Network, and a clean, modern interface for sending, receiving, and swapping assets.

Key features include:

• Account Abstraction Smart Wallet: Users can create and manage smart-contract–based wallets, send and receive ETH and ERC-20 tokens easily, and interact with blockchain without managing private keys directly.
• AI Agent: Integrated AI assistant available on every page guides users, explains actions, and answers questions in chat, making Web3 more accessible.
• Real-Time Token Prices: Live portfolio valuation in USD and ETH using Pyth Network data.
• Token Management & Swaps: Supports ETH ↔ WETH swaps directly in the wallet with a fast, intuitive UI.
• Settings & Security: Includes log-out functionality and local data management, with planned updates for theme switching, wallet recovery, and advanced security controls.

Nexa Wallet is a full-stack Web3 application combining smart contract logic with a modern frontend. At its core, it uses Account Abstraction (ERC-4337) to manage smart accounts, enabling users to send and receive ETH and ERC-20 tokens without manually handling private keys.

The frontend is built with Next.js and TypeScript, providing a clean, responsive, and intuitive interface. Ethers.js handles blockchain interactions, including sending transactions, bundling UserOperations, and querying smart contracts.

Token price data is integrated from Pyth Network, giving users live and accurate valuations in USD and ETH.

The backend is built with Flask, which hosts the AI assistant (uAgent via ASI:One). Frontend requests are sent to the Flask server, where the AI processes them and returns guidance, explanations, or transaction instructions directly to the user interface.

By combining AA smart wallets, AI assistance, real-time price feeds, and a polished frontend, Nexa Wallet delivers a seamless, secure, and intelligent Web3 experience.
