Block explorers for StarkNet

What are block explorers?

Block explorers give everyone, regardless of technical expertise, an easy way to search a blockchains activity. You may already be familiar with Etherscan, the OG block explorer for Ethereum. With Etherscan, you can effortlessly find data about transactions, addresses, blocks, fees, and more.

Etherscan has proven to be an incredibly popular tool that other blockchains have copied it, giving rise to Polygonscan, Arbiscan, and FTMscan, amongst others. For EVM chains such as Polygon, Arbitrum, and Fantom, it’s easy to re-use this existing, popular, and well-polished tool. 

But StarkNet is built differently, and therefore, a block explorer had to be created from scratch!

We’ll take you through the current block explorers for StarkNet and show the same wallet across all explorers to see how they compare.

Now let's go through them:

1. Voyager

Built by the Nethermind team, Voyager is the first block explorer for StarkNet. As you would expect, it’s possible to search by block, transactions, or contracts (including wallets). With its clean and minimal UI, Voyager is an essential component on StarkNet, providing users with transparency and convenience.

3. Viewblock

ViewBlock's StarkNet explorer provides transaction and event decoding, token prime support, and advanced statistics. In addition to supporting all the basics of the chain, like viewing blocks, transactions, messages, events, and classes, most transactions and events are properly decoded. This makes it really easy to understand what's happening on StarkNet.

As you can see in the screenshots below, Viewblock offers a rich data and visualization experience, as well as providing handy USD summary views of a contract and NFT support.
