Arkham's integration with Optimism positively impacts both end users and developers in meaningful ways. Users gain real-time transaction tracking, portfolio management, and network visualization on Optimism's L2 Rollup. Developers benefit from an enriched ecosystem with detailed on-chain data. This work bridges the gap between the address-centric world of crypto and the rest of the entity-centric world, including TradFi and Web2. This collaboration fosters broader adoption and a vibrant developer community, aligning with Optimism's vision for a decentralized, accessible, and healthy blockchain ecosystem​. Arkham also integrated Base (built on the OP Stack) with 130K active entities, 50M labeled addresses, and 70M tags.
