eth_getLogs

Parameters

Object - The filter options:

  • fromBlock: QUANTITY|TAG - (optional, default: "latest") Hexadecimal block number, or "latest" for the last mined block, "safe" for the latest safe block, "finalized" for the latest finalized block, or "earliest" for not yet mined transactions.
  • toBlock: QUANTITY|TAG - (optional, default: "latest") Hexadecimal block number, or "latest" for the last mined block, "safe" for the latest safe block, "finalized" for the latest finalized block, or "earliest" for not yet mined transactions.
  • address: DATA|Array, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate.
  • topics: Array of DATA, - (optional) Array of 32 Bytes DATA topics. Topics are order-dependent. Each topic can also be an array of DATA with β€œor” options.
  • blockhash: DATA, 32 Bytes - (optional) Per EIP-234, blockHash restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to fromBlock = toBlock = the block number with hash blockHash. If blockHash is present in the filter criteria, then neither fromBlock nor toBlock are allowed.

Returns

Array - Array of log objects, or an empty array if nothing has changed since last poll.

For filters created with eth_newBlockFilter the return are block hashes (DATA, 32 Bytes), e.g. ["0x3454645634534..."].

For filters created with eth_newPendingTransactionFilter the return are transaction hashes (DATA, 32 Bytes), e.g. ["0x6345343454645..."].

For filters created with eth_newFilter logs are objects with following params:

  • removed: TAG - true when the log was removed, due to a chain reorganization. false if its a valid log.
  • logIndex: QUANTITY - Hexadecimal log index position in the block. null when its pending log.
  • transactionIndex: QUANTITY - Hexadecimal of the transactions index position log was created from. null when its pending log.
  • transactionHash: DATA, 32 Bytes - Hash of the transactions this log was created from. null when its pending log.
  • blockHash: DATA, 32 Bytes - Hash of the block where this log was in. null when its pending. null when its pending log.
  • blockNumber: QUANTITY - Hexadecimal of the block number where this log was in. null when its pending. null when its pending log.
  • address: DATA, 20 Bytes - Address from which this log originated.
  • data: DATA - Contains zero or more 32 Bytes non-indexed arguments of the log.
  • topics: Array of DATA - Array of 0 to 4 32 Bytes DATA of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)
