smlXL aims to make public computers (blockchains) more accessible and understandable by enabling exploration and discovery. Its first focus is providing a far richer understanding of the semantics of blockchain activity, making data and information accessible and useful to all. Its products include evm.codes, the go-to place for people seeking EVM opcodes or wanting to learn about the Ethereum Virtual Machine and evm.storage, which allows users to deeply scrutinize the storage of any contract on the Ethereum or Avalanche blockchains.
