Blockscout
Blockscout is an open-source multichain block explorer for Ethereum Virtual Machine (EVM) based chains, providing comprehensive blockchain data and developer tools.
Overview
Blockscout is an open-source, multichain block explorer designed for Ethereum Virtual Machine (EVM) compatible blockchains, including layer 1s, optimistic rollups, zk rollups, and more. It supports over 1000 blockchain networks, offering a unified interface to explore blocks, transactions, accounts, tokens, and decentralized applications (dApps) across multiple chains. Blockscout aims to simplify blockchain data access by consolidating cross-chain information into a single platform, making it easier for developers, analysts, and users to track and verify on-chain activity without switching between different explorers.
The platform provides comprehensive smart contract coverage, including verification, publishing, and interaction capabilities. Users can read and write to contracts, inspect token transfers, analyze ERC20 movements, and explore NFTs with rich metadata. Blockscout also integrates DAppscout, a marketplace for discovering and interacting with trusted dApps across supported networks, complete with user reviews and ratings. Real-time network statistics such as gas fees and transaction trends are available to help users make informed decisions.
Blockscout stands out due to its open-source nature, community-driven development, and extensive multichain support. Unlike many proprietary explorers, its codebase is publicly accessible, allowing transparency, security audits, and contributions from developers worldwide. It supports a wide range of EVM chains including Ethereum, Optimism, Arbitrum, Polygon PoS, Base, and many others, making it a versatile tool for projects operating across multiple ecosystems. Developers can self-host Blockscout or use its Explorer as a Service (EaaS) for enterprise-grade hosting. Comprehensive documentation and APIs facilitate integration into developer workflows, enabling advanced analytics, contract verification, and blockchain data querying.
To get started, users can visit the Blockscout website to explore supported chains or deploy their own instance using the open-source code. The documentation provides guides for using the explorer, integrating APIs, running self-hosted instances, and migrating from other explorers. Community support is available via Discord, Telegram, and X, fostering collaboration and continuous improvement.
The Problem
Blockchain users and developers often face fragmented data access across multiple EVM-compatible chains, requiring them to switch between different explorers to track transactions, tokens, and smart contracts. This fragmentation complicates cross-chain analysis and slows down development workflows.
