Viem 2.33 introduces initial support for Flashblocks as a first-class citizen! Try it out in Viem or Wagmi by importing a chain that supports preconfirmations – starting with `basePreconf` + `baseSepoliaPreconf`. Then observe sub-200ms transaction confirmation times. 🫡

More things coming soon: subscribing to preconfirmed blocks, etc.

@amdaddeo So you'll just need to chuck their url in the `http` or `webSocket` transport, coupled with `basePreconf`.

@amdaddeo Once enough providers have support for Flashblocks, we can prob merge it into the `base` chain.

Note: `basePreconf` = `base` with preconf config `baseSepoliaPreconf` = `baseSepolia` with preconf config

@amdaddeo try put some `()`s between the calls

@amdaddeo *fetch the receipt from the hash in a preconf block
