L2scan

L2scan is a block explorer that appeared in 2023, indexing several Ethereum rollups including Scroll, Linea and zkSync and placing them behind a single query interface. Conventionally each Layer 2 has its own explorer, so tracking one address across chains means switching between interfaces; this tool normalizes multichain data and offers unified search, aggregating cross-rollup activity per address while also exposing individual transactions and decoded contract call parameters.

It adds an AI layer to the query path: users describe what they need in natural language and the system converts the description into retrieval conditions instead of requiring hand-built filters. For a zero-knowledge rollup such as Scroll, an explorer must also show how batch submission, proof generation and Layer 1 finality relate to each other, which is the main difference from a Layer 1 explorer. It is categorized as a rollup data and explorer tool.
