Block Explorer

Block explorers are essential tools for blockchain networks, providing users with a way to view and analyze transactions, blocks, and other on-chain data. For RollApp developers on the Dymension network, integrating a block explorer is crucial for transparency and user engagement.

This guide will walk you through the various options available for integrating a block explorer with your RollApp. Whether you choose to run your own explorer or use an external service, you'll find the information you need to get started.
