eth_getBlockByNumberwith pending tag.eth_getTransactionReceipt, it checks if it exists in the DB first, if not, then maybe it's a flashblock receipt then it checks in the cacheeth_getBalancewith pending tag.It runs a websocket client and listens to the rollup-boost web proxy. It parses the message and store the necessary information into the cache.
For message out of order scenarios, currently only handles to not updating older blocks, but doesn't handle cases like same block payload message out of order, will be TODO for future updates.
Verified locally and devnet.
