ChainGazer од Semeon

ChainGazer is a lightweight, privacy-first Ethereum address monitor that runs in your browser sidebar. Add any wallet address or ENS name to your watchlist and keep an eye on ETH balances and ERC-20 token holdings — all without connecting a wallet or signing anything.

Your watchlist is stored locally and syncs across devices through your browser account. No data is sent to third-party servers.
Balance data is fetched directly from Blockscout's public API, and ENS names are resolved on-chain.

Features:
- Add unlimited Ethereum addresses or ENS names
- View ETH and ERC-20 token balances at a glance
- Drill into any wallet for a full token breakdown
- Search and reorder your watchlist
- Export and import your watchlist as JSON
- Dark and light themes
- Zero permissions beyond storage — no access to your browsing data
