Module forest_filecoin::rpc::methods::eth::filter

Ethereum Event Filters Module

This module provides the structures and logic necessary to manage filters for Ethereum events, tipsets, and mempool operations. Ethereum event filters enable clients to monitor and subscribe to changes in the blockchain, such as log events, pending transactions in the mempool, or new tipsets in the chain. These filters can be customized to capture specific events or conditions based on various parameters.

Filter Types:

• Event Filter: Captures blockchain events, such as smart contract log events, emitted by specific actors.
• TipSet Filter: Tracks changes in the blockchain’s tipset (the latest set of blocks).
• Mempool Filter: Monitors the Ethereum mempool for new pending transactions that meet certain criteria.
