Limitations:
- Only supported for Solana and for confirmation level Finalized,
which the token/NFT bridges use. Need to take a close look before
enabling it for both (since we're bypassing the tx fetcher and would
fetch and process accounts of the "wrong" confirmation levels).
- Rate limiting not implemented yet, will be done in a future release
when things are not currently on fire.
