TRANSPARENCY


OPEN SOURCE

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!

Features
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.

More Features
Rollup Compatible
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.

Industry leaders use Blockscout
“The Blockscout team has been incredibly responsive in swiftly spinning up block
explorers with the features we need, whenever we need them.”
Kevin Ho
Optimism
“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.”
Liam DiGregorio
Evmos
“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!”
Griff Green
Giveth
“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.”
Pol Lanski
Dappnode
“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.”
Maarten Henskens
Astar Network
“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.”
Freddy Zwanzger
Blockdaemon
“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.”
Valentin Rodygin
Celo
“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.”
‍Sky
DXDao
“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.”
Bogdan Habic
Tenderly
“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.”
Stefan George
Gnosis
“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.”
Alejandro Cavallero
RSK
“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!”
Gubsheep
Dark Forest
“For zkEVM testnet I used Polygon scan and Blockscout, and I now realize two
block explorers are kind of better than just one.”
Francis Thomas
Polygon Labs
