## What it is
Blockscout is an open-source blockchain explorer for inspecting and analyzing EVM-based chains, supporting Ethereum mainnet, L2s, sidechains, testnets, and private networks. It provides a web UI for searching transactions, addresses, and tokens, contract verification and interaction, and REST, JSON-RPC, and GraphQL APIs, deployable via Docker, Kubernetes, or managed hosting.

## Use cases
- run a self-hosted block explorer for my EVM chain
- search and inspect transactions and addresses on Ethereum
- verify and interact with smart contracts in a browser
- get an open-source Etherscan alternative for my L2 or sidechain
- query blockchain data via REST or GraphQL APIs
- index and analyze an EVM testnet or private network
- explore ERC-20 and ERC-721 token transfers
- launch an explorer for a new rollup

## When to choose
- you need a transparent, open-source explorer for any EVM-compatible chain
- you want to self-host an explorer with full API access
- you need contract verification and read/write interaction out of the box
- you support multiple chains, L2s, or rollups and need multi-chain coverage

## When to avoid
- your chain is not EVM-compatible (e.g., Bitcoin, Solana)
- you only need a lightweight wallet or node dashboard rather than a full explorer
- you cannot provision the database and indexer resources Blockscout requires
