Table Description

The zksync.logs table represents the logs generated by the Ethereum Virtual Machine (EVM) when a contract is executed. Logs are a way to store data on the blockchain. Logs originate from events that occur during the execution of a smart contract. A log consists of:

  • topic list: a list of 0 to 4 32-byte data topics. Topic0 is the hash of the signature of the event (indexed), and the remaining topics are indexed parameters of the event.
  • data: contains non-indexed data.
This is the raw version of this table. If the chain is a Fully Managed chain, decoded transaction calls will be available, see call tables section. If this is a Hosted chain, decoded call tables will not be available.
