- The topic zero is based on the keccak-256 hash of the log event's method signature.

- Since there are multiple price feed contract address that all use the same `LogValue` event, we have a special implementation of a fetcher specifically for price feeds that can query using all of the contract addresses at once, thus only needing to make one call to the blockchain. - Since there are multiple price feed contract address that all use the same `LogValue` event, we have a special implementation of a fetcher specifically for price feeds that can query using all of the contract addresses at once, thus only needing to make one call to the blockchain.
