Hetherscan

Hetherscan is a superset of Betherscan by tiagofneto, focusing on adding Diamond Contract support and various ways to interact with the Herodotus Storage Proofs API from within the block explorer.

Hetherscan is a browser extension designed to enhance the user experience on block explorer platforms. By integrating additional information directly into the pages, Hetherscan aims to provide a more comprehensive view of blockchain data, making it easier for developers and advanced users to gather all the information they need without the need to navigate away from the explorer.
