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.
- Filters expire after 5 minutes of inactivity (no queries).
- To ensure reliability, eth_newFilter limits the block range 10,000 blocks.
Parameters
- 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.
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)"
