anyOf
For filters created with kaia_newBlockFilter, the return are block hashes (32-byte DATA), e.g., ["0x3454645634534..."].
string
For filters created with kaia_newPendingTransactionFilter, the return are transaction hashes (32-byte DATA), e.g., ["0x6345343454645..."].
string
For filters created with klay_newFilter logs are objects with following properties
true when the log was removed, due to a chain reorganization. false if its a valid log.
Integer of the log index position in the block. null when it is a pending log.
Integer of the transactions index position log was created from. null when pending.
Hash of the transactions this log was created from. null when pending.
Hash of the block where this log was in. null when pending.
The block number where this log was in. null when pending.
Address from which this log originated.
Contains the non-indexed arguments of the log.
