Show the ETH balance
of any address.
A minimal Chrome extension. Paste an Ethereum address, read its balance, close the popup. No account, no wallet connection, 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 the RPC endpoint 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 https://ethereum.publicnode.com. 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 this extension drain my wallet?
No. There is no code path that requests a signature. The extension only reads the public balance of an address via a standard JSON-RPC call — 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 https://ethereum.publicnode.com only when you click the action button, to read the public balance. It is never sent to us.
Does it work with hardware wallets (Ledger, Trezor)?
Yes — paste the public address shown on your device. We never ask the device to sign anything.
