Blockscout is optimized for next-level blockchain exploration. Multichain, highly configurable, and open source, the explorer portal opens up access to all chain data and functionality. Search blocks, transactions and addresses, then go beyond to connect and interact with apps, bridges, wallets and more. The blockchain universe is yours to explore!
Blockscout is the first fully-featured open-source blockchain explorer available for use by any Ethereum Virtual Machine (EVM) chain. Utilized by 200+ networks across the blockchain continuum, Blockscout gives everyone access to essential on-chain data, the ability to interact with smart contracts, and the tools to view and verify transactions quickly and easily.
As rollup popularity and usage increases, so does the need for an explorer designed to support both zk and optimistic L2 rollup-based transactions. Blockscout gives users full tracking capabilities to follow transactions as they move cross-chain, cross-layer, and across the blockchain ecosystem. Easily explore data on EVM-compatible rollups such as Optimism, Arbitrum, ZK rollups and more.
Open Source
Blockscout is designed for transparency and optimized data discovery, providing users with simple and easy access to extensive blockchain data with the ability to incorporate off-chain data as well. The open-source code is well documented and independently verifiable.
Extensibility
Blockscout functionality is customizable, extendable, and ready for your enhancements. Easily customize the UI, expand the product feature set, update current features, and integrate with third-party software to make it your own.
Optimized Data Discovery
Get the big picture view then dig into the details. Optimized views and integrations with 3rd party services like Tenderly provide the opportunity for granular data exploration.
Real-Time Updates
Dynamic displays update data from the latest blocks, transactions, balances, and token transfers all in real-time.
Advanced Token Support
Blockscout supports ERC20, ERC721, ERC677 and ERC1155 token standards for both native and bridged tokens on a supported chain. Features like “Add to Metamask” provide easy one-click interactivity. Off-chain metadata for tokens provides a better user experience
Next-level Smart Contract Verification
Contract verification has never been easier! Sourcify and HardHat integrations are available, or choose native verification built directly into the Blockscout interface.
API Accessibility
Blockscout APIs are optimized and ready to use. Test calls directly from a web interface with GraphQL, or query using Eth-based and custom RPC methods.
Diverse ‍Client Support
Supported clients include OpenEthereum, Nethermind, Geth, Erigon, Besu, Ganache, and Substrate.
App Integrations
In-built app marketplace
My Account functionality
Data tagging

Deploy Yourself
Blockscout is built for easy access and customization. If you are a developer looking to deploy for your chain, our step-by-step documentation guides you through the process.
Projects looking for assistance and an all-inclusive approach can take advantage of our subscription and hosting services. We'll deploy your Blockscout explorer instance with branding customizations and maintain the latest updates and features to support your user base.
“We are very grateful for open-source tooling like Blockscout which allows developers to easily share on-chain statistics with their communities so they can focus on building other things.”
“Blockscout is critical infrastructure for Ethereum and the multi-chain family tree. A fully open source block explorer means data transparency and unrestricted community access. It’s essential for our success!”
“Blockscout is a beacon of light in an ecosystem of closed source block explorers. The information on-chain needs an easy way to be accessed. At Dappnode we’ve deployed instances of Blockscout for internal testnets and they were an integral part of our flow.”
“With the initial launch of EVM in our multi-virtual machine environment, usage and building with reliable infrastructure partners is very important. Blockscout gave us support from day 1 with great service making them our number 1 EVM explorer.”
“What I like about Blockscout is that it is freely available (hosted or self-hosted) and is often the best if not only explorer option for smaller EVM-based blockchain networks.”
“Blockscout helped us tremendously in the early stages of our growth. Thanks to Blockscout, we managed to quickly get a very robust, reliable and extendable block explorer. Working closely with the team gave us an opportunity to stay up to date with the latest features and provide valuable data to our community.”
“Blockscout is a proud and wonderful web3 example of open source software delivering true value to over 100 communities who would have had to reinvent the chain explorer over and over. It also provides a highly valuable additional check on the closed-source path.”
“We love the Blockscout team and their open-source ethos! We share their vision for data availability and information transparency. Blockscout gives blockchain users access to the data and views they need to succeed. This is why we've integrated with them so that users can benefit from both platforms.”
“Blockscout is the most competitive and complete open source block explorer for analyzing any EVM based blockchain or L2. Blockscout powers Gnosis Chain as well as the L2s running on top.”
“Blockscout has been supporting Rootstock for many years. It is a useful tool for end-users, and a powerful option for developers that are in need of an API to query the blockchain in a free and accessible way. I have great expectations about the future of Blockscout and the partnership with Rootstock.”
“The team behind Blockscout and xDAI were instrumental to making Dark Forest, the decentralized ZK space warfare game that spawned the on-chain gaming industry, a success. This team has been doing fantastic work, building critical infrastructure for blockchain developers and users!”
