   - [x] i think the server isn't following the spec. we need a context attached to more errors so we know which one
   - [x] make jsonrpc default to "2.0" (including the custom deserializer that handles the RawValues)

-- [ ] use siwe messages and signatures for sign up and login
-- [ ] "chain is forked" message is wrong. it includes nodes just being on different heights of the same chain. need a smarter check
-  - i think there is also a bug because 0xllam4 ran a benchmark and get a bunch of errors back

 - [x] if the eth_call (or similar) params include a block, we can cache for that
 - [x] when block subscribers receive blocks, store them in a block_map
 - [x] eth_blockNumber without a backend request

   - [x] send getTransaction rpc requests to the private rpc tier
 - [x] I'm hitting infura rate limits very quickly. I feel like that means something is very inefficient
   - whenever blocks were slow, we started checking as fast as possible

   - will need all Block<TxHash> **and** Block<TransactionReceipt> in caches or fetched efficiently
   - so maybe we don't want this. we can just use the general request cache for these. they will only require 1 request and it means requests won't get in the way as much on writes as new blocks arrive.
   - after looking at my request logs, i think its worth doing this. no point hitting the backends with requests for blocks multiple times. will also help with cache hit rates since we can keep recent blocks in a separate cache
