Track any wallet.
Across every chain.
Web3 Tracker is a Chrome extension that displays read-only crypto balances for Ethereum, BNB Chain, Polygon, Arbitrum, Base, Optimism, Avalanche, and Solana — straight from your browser toolbar. No login. No seed phrase. No background tracking.
Read-only by design
The extension has no signing code. It cannot send transactions, sign messages, or move funds — even if every RPC node you queried were malicious.
No account, no keys
You paste a public address, you read a number. We never ask for a private key, seed phrase, or wallet connection prompt.
Hardened CSP
The extension's Content-Security Policy pins outbound connections to a declared list of RPC hosts. A compromised dependency still cannot phone home.
Minimal permissions
Only storage — to remember the last address you looked up. No tabs, no cookies, no history, no host access on the sites you visit.

Common questions
Can Web3 Tracker drain my wallet?
No. There is no code path that requests a signature. The extension only reads public on-chain data via standard JSON-RPC calls — the same kind any block explorer makes.
Do you collect analytics or track my browsing?
No. The extension contains no analytics SDK, no fingerprint, and no third-party scripts. It does not read, modify, or track the websites you visit.
What happens to the address I type?
It is stored locally on your device using chrome.storage.local so you don't have to retype it next time. It is sent to a public blockchain RPC endpoint only when you click "Fetch Balance". It is never sent to us.
Can I track someone else's wallet?
Yes — public chain data is public. This is identical to viewing an address on Etherscan, just faster.
