Monitor blockchain addresses, check balances, and track portfolio across multiple chains. Monitor blockchain addresses, check balances, and track portfolio across multiple chains. What it does. Blockfolio: Address Monitor lets you resolve a blockchain wallet address or transaction hash and jump straight to the right block explorer. You can paste a value into a Chrome side panel, or select an address/hash on any web page and use the right-click menu "Open in Blockchain Explorer" to open the matching explorer in a new tab. The extension detects the network locally and builds the correct explorer URL — it never fetches balances itself. Key features (found in code): - Side-panel UI (`sidepanel.html`) opened via `chrome.sidePanel` (background.js:217) - Right-click context-menu action "Open in Blockchain Explorer" via `chrome.contextMenus` (background.js:187, background.js:200) - Opens the matching block explorer (arbiscan.io, basescan.org, blockchair.com, bscscan.com, etherscan.io, explorer.solana.com…) in a new tab - Local search/lookup history, stored locally in `chrome.storage.local` (background.js:242) Who it's for. Crypto users, traders and analysts who frequently need to inspect addresses or transactions across multiple chains. No background data collection, no ads, no tracking, no account required.
