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.
