In cases where users have an enormous amount of tokens, we don't want to slow down our Price API with large requests. To combat this, when fetching token rates, send requests in batches of 100.

Hmm, I don't totally follow why this additional branch was needed here. Is it now possible for tokenValue to be falsey?

Realistically, no, but because I've changed #fetchAndMapExchangeRatesForUnsupportedNativeCurrency to use #fetchAndMapExchangeRatesForSupportedNativeCurrency, contractExchangeRates is now a type of ContractExchangeRates, and that is defined as:
interface ContractExchangeRates {
[address: string]: number | undefined;
}So that means that tokenValue here is number | undefined.

Interesting.... that | undefined seems like a mistake, I don't see a case where it is undefined.
Pre-existing issue though, and not a blocker, this doesn't really hurt
