Quick Block Explorer

Instantly search any transaction or wallet address across multiple blockchains.

Instantly look up any blockchain transaction or wallet address across 9 networks. What it does. Quick Block Explorer 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 Quick Block 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.
