Large amounts of network requests

[rawfalafel]

After instantiating @burner-wallet/core, I noticed that the library sends over 300 requests per minute with a simple setup. They're duplicate requests for eth_blockNumber and eth_getLogs. Can I configure the library to dedupe these requests or reduce the polling rate?

also for token prices polling requests, might can optimize with https://github.com/MyCryptoHQ/eth-scan , which make fetching Ether or (ERC-20) token balances for multiple addresses in an efficient way
