  Chainlens, built by Web3 Labs, is a blockchain explorer and analytics platform for EVM-compatible public and private
  chains (Ethereum, Hyperledger Besu, Quorum, Polygon, Avalanche, BNB Chain, etc.) as well as Substrate-based chains. It
  combines a user-friendly block explorer with powerful REST APIs for real-time transaction monitoring, smart contract
  verification, token and NFT tracking (ERC-20, ERC-721, ERC-1155), and integration of on-chain data with existing
  analytics and reporting pipelines. The API follows the EIP-3091 block explorer route conventions and is offered both
  as SaaS and self-hosted.
