API Reference

eth_getLogs

Returns an array of all logs matching a given filter object.

📘

Supported on Arbitrum Nova only.

Parameters

  • object - The filter options in the following shape:
    • fromBlock - Integer block number encoded as a hexadecimal, "latest","pending", or "earliest" tags.
    • toBlock - Integer block number encoded as a hexadecimal, "latest","pending", or "earliest" tags.
    • address - Contract address or a list of addresses from which logs should originate.
    • topics - Array of DATA topics. Topics are order-dependent.
    • blockhash - (optional) With the addition of EIP-234, blockHash will be a new filter option which 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 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:
    • removed - Boolean true if log was removed, due to a chain reorganization. false if its a valid log.
    • logindex - Integer of log index position in the block encoded as a hexadecimal. null if pending.
    • transactionindex - Integer of transactions index position log was created from. null if pending.
    • transactionhash - Hash of the transactions this log was created from. null if pending.
    • blockhash - Hash of the block where this log was in. null when its pending. null if pending.
    • blocknumber - The block number where this log was, encoded as a hexadecimal. null if pending.
    • address - The address from which this log originated.
    • data - Contains one or more 32 Bytes non-indexed arguments of the log.
    • topics - Array of 0 to 4 32 Bytes of indexed log arguments.
