Get harmony logs for smart contracts or transactions
- 1.
Object
- The filter options: - 2.
fromBlock
:QUANTITY|TAG
- (optional, default:"latest"
) Integer block number, or"latest"
for the last mined block or"pending"
,"earliest"
for not yet mined transactions. - 3.
toBlock
:QUANTITY|TAG
- (optional, default:"latest"
) Integer block number, or"latest"
for the last mined block or"pending"
,"earliest"
for not yet mined transactions. - 4.
address
:DATA|Array
, 20 Bytes - (optional) Contract address or a list of addresses from which logs should originate. - 5.
topics
:Array of DATA
, - (optional) Array of 32 BytesDATA
topics. Topics are order-dependent. Each topic can also be an array of DATA with "or" options. - 6.
blockhash
:DATA
, 32 Bytes - (optional) ,blockHash
is a new filter option which restricts the logs returned to the single block with the 32-byte hashblockHash
. UsingblockHash
is equivalent tofromBlock
=toBlock
= the block number with hashblockHash
. IfblockHash
is present in the filter criteria, then neitherfromBlock
nortoBlock
are allowed.
For filters created with
hmy_newBlockFilter
the return are block hashes (DATA
, 32 Bytes), e.g. ["0x3454645634534..."]
.For filters created with
hmy_newPendingTransactionFilter
the return are transaction hashes (DATA
, 32 Bytes), e.g. ["0x6345343454645..."]
.For filters created with
hmy_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
- integer of the log index position in the block.null
when its pending log.transactionIndex
:QUANTITY
- integer 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
- 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 the non-indexed arguments of the log.topics
:Array of DATA
- Array of 0 to 4 32 BytesDATA
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 theanonymous
specifier.)
