MetaMask Connection Demo

Connect securely with your MetaMask wallet in the browser — no sign-up, no login form. This interactive example demonstrates a safe, minimal integration of wallet-based authentication.

About This Demo

This single-page demo lets you connect your MetaMask wallet to see how decentralized applications (dApps) interact with browser wallets. The connection happens locally — your private keys never leave MetaMask. You are simply granting permission for this page to read your public address and fetch your balance.

How It Works

When you click “Connect MetaMask,” your browser checks for an injected Ethereum provider (the interface MetaMask exposes). If MetaMask is installed, it will ask for permission to access your wallet address. Once connected, this page displays your public address, network ID, and balance, all fetched via standard blockchain JSON-RPC calls.

Why Use Wallet Connections

Traditional web apps rely on usernames and passwords stored in databases. Wallet connections are different — they use cryptographic proof of ownership. Your wallet signs data directly on your device. The website never stores sensitive data or handles passwords. This makes connections more secure and decentralized.

Security Best Practices

Always verify the website you’re connecting to and confirm which account is being accessed. Never enter your seed phrase, recovery phrase, or private key into a website. If a page asks for those, close it immediately. This demo never requests or stores private data. All communication happens through your local MetaMask instance.

Privacy Note

Connecting a wallet reveals only your public address to the page. Your transactions remain visible on-chain but are never stored here. This site does not track, analyze, or transmit your wallet data. Disconnect your wallet anytime from MetaMask’s interface.
