Exchange Balance Watcher

Read-only balance viewer for Binance, Bybit and OKX. See your balances with a read-only API key — no trading or withdrawals.

Exchange Balance Watcher is a simple, read-only balance viewer for your Binance, Bybit or OKX account. Enter a read-only API key (and secret, plus passphrase for OKX) and instantly see your non-zero balances across the exchange you connect. The extension only calls the exchange's account/wallet-balance endpoint — no order, transfer or withdrawal endpoint exists anywhere in the code, so your funds can never be moved through this extension. Your API key never leaves your browser except in direct, signed requests to the exchange you connected. Keys are stored locally in Chrome's storage, scoped to this extension and this browser profile only — nothing is sent to any third-party server. Features: - Connect multiple exchanges (Binance, Bybit, OKX) at once - See all non-zero balances in one compact popup - Remove a connected exchange anytime - Fully read-only by design — no trading, transfer or withdrawal capability For your safety, always create an API key with trading and withdrawals disabled on the exchange side.
