eth_newFilter​

Creates a filter object, based on filter options, to notify when the state changes (logs). To check if the state has changed, call eth_getFilterChanges.

A note on specifying topic filters:​

Topics are order-dependent. A transaction with a log with topics [A, B] will be matched by the following topic filters:

  • [] "anything"
  • [A] "A in first position (and anything after)"
  • [null, B] "anything in first position AND B in second position (and anything after)"
  • [A, B] "A in first position AND B in second position (and anything after)"
  • [[A, B], [A, B]] "(A OR B) in first position AND (A OR B) in second position (and anything after)"
Parameters​
  1. 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.

eth_getFilterLogs​

Returns an array of all logs matching filter with given id.

Parameters​
  1. QUANTITY - The filter id.
Example Parameters​
params: [
  "0x16", // 22
];
Returns​

See eth_getFilterChanges

Example​
// Request
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getFilterLogs","params":["0x16"],"id":74}'

Result see eth_getFilterChanges

eth_getLogs​

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

Parameters​
  1. 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) With the addition of EIP-234 (Geth >= v1.8.13 or Parity >= v2.1.0), blockHash is 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 the filter criteria, then neither fromBlock nor toBlock are allowed.
Example Parameters​
params: [
  {
    topics: [
      "0x000000000000000000000000a94f5374fce5edbc8e2a8697c15331677e6ebf0b",

Info

The maximum number of traces per request is configurable via the rpc.trace.maxTracesPerRequest configuration parameter (default: 10000). Use the after and count parameters for pagination when dealing with large result sets.
