eth_getLogs

Last updated
Returns an array of all logs matching a given filter object.
This method will use 80
.
Object
- The filter options:
fromBlock
: QUANTITY|TAG
- (optional, default: "latest"
) Integer block number, or "latest"
for the last mined block or "pending"
, "earliest"
for not yet mined transactions.
toBlock
: QUANTITY|TAG
- (optional, default: "latest"
) Integer block number, or "latest"
for the last mined block or "pending"
, "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 "or" options.
blockhash
: DATA
, 32 Bytes - (optional, future) 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.
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
- 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 one 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.)
