To use the eth_getLogs method on the C-Chain, ensure that the end of your URL includes ext/bc/C/rpc.

Parameters

object

object

The transaction call object which contains the following fields:

fromBlock

string

The block number as a string in hexadecimal format or tags. The supported tag values include earliest for the earliest/genesis block, latest for the latest mined block, pending for the pending state/transactions, safe for the most recent secure block, and finalized for the most recent secure block accepted by more than 2/3 of validators

toBlock

string

The block number as a string in hexadecimal format or tags. The supported tag values include earliest for the earliest/genesis block, latest for the latest mined block, pending for the pending state/transactions, safe for the most recent secure block, and finalized for the most recent secure block accepted by more than 2/3 of validators

address

string

The contract address or a list of addresses from which logs should originate

topics

array

An array of DATA topics and also, the topics are order-dependent. Visit this official page to learn more about topics

blockHash

string

With the addition of EIP-234, blockHash is a new filter option that restricts the logs returned to the block number referenced in the blockHash. Using the blockHash field is equivalent to setting the fromBlock and toBlock to the block number the blockHash references. If blockHash is present in the filter criteria, neither fromBlock nor toBlock is allowed

Returns

array

array

An array of log objects, or an empty array if nothing has changed since last poll:

address

string

An address from which this log originated

topics

array

An array of zero to four 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 declare the event with the anonymous specifier

data

string

It contains one or more 32 Bytes non-indexed arguments of the log

blockNumber

string

The block number where this log was in. null when it's a pending log

transactionHash

string

The hash of the transactions this log was created from. null when its a pending log

transactionIndex

string

The integer of the transaction's index position that the log was created from. null when it's a pending log

blockHash

string

The hash of the block where this log was in. null when it's a pending log

logIndex

string

The integer of the log index position in the block. null when it's a pending log

removed

boolean

It is true when the log was removed due to a chain reorganization, and false if it's a valid log
