Blockscout is a fully open-source blockchain explorer designed for Ethereum Virtual Machine (EVM) compatible chains, including layer 1 blockchains, sidechains, and layer 2 rollups. It supports over 1000 blockchain networks, providing a unified interface to explore blocks, transactions, wallet addresses, tokens, and decentralized applications (dApps) across multiple chains. Blockscout aims to offer transparency and accessibility for both novice users and experienced developers by delivering comprehensive blockchain data and advanced tools such as smart contract verification, interaction, and optimized APIs.

The platform's multichain search capability allows users to query transactions, token transfers, smart contracts, and addresses across many EVM-based networks simultaneously, eliminating the need to switch between different explorers. Blockscout also integrates DAppscout, a dApp marketplace that helps users discover and interact with trusted decentralized applications on supported chains. Its open-source nature ensures continuous community-driven improvements, security audits, and transparency, making it a reliable alternative to centralized explorers like Etherscan.

Developers and enterprises can self-host Blockscout or use its Explorer as a Service (EaaS) for production-grade deployments. The project offers extensive documentation covering manual, Docker, Kubernetes, and Ansible deployment methods, along with configuration options and environment variables. Blockscout's APIs and SDK enable integration of blockchain data into custom applications, supporting use cases such as transaction monitoring, token analytics, NFT exploration, and smart contract auditing. The platform is actively maintained with a vibrant community on Discord, Telegram, and X (Twitter).
