About Nexus Web3
A modern Web3 portfolio interface that lets you connect your Ethereum wallet and view your on-chain balances with no sign-ups, no middlemen, and no custody risk.
What It Does
This application connects directly to the Ethereum Mainnet through your browser wallet. Once connected, it reads your on-chain data in real time:
- Native ETH balance on Ethereum Mainnet
- USDT (Tether) ERC-20 token balance
- Wallet connection state with clear visual feedback
- Network detection and address display

Why Web3?
Traditional finance requires intermediaries such as banks, brokers, and custodians, each adding fees, delays, and counterparty risk. Web3 eliminates these layers by letting users interact directly with the blockchain.
Your keys, your coins. This interface never asks for a password, never stores your private key, and never moves your funds. It simply reads public blockchain data through your wallet's connection.
FAQ
Do I need MetaMask to use this?
MetaMask is the most common option, but any injected Ethereum wallet (Coinbase Wallet, Brave Wallet, etc.) or WalletConnect-compatible mobile wallet will work.
Is my private key shared with this site?
Never. The app only reads your public address and on-chain balances. Your private key stays in your wallet at all times.
Why do I see 0.00 USDT?
If your wallet doesn't hold USDT on Ethereum Mainnet, the balance will be zero. USDT on other chains (Tron, BSC, etc.) is not displayed.
What network does this support?
Currently, Ethereum Mainnet only. Support for additional chains may be added in the future.
Are the Send/Receive/Swap buttons functional?
Not yet. They are designed as a preview of the planned feature set. The current scope focuses on wallet connection and balance display.
