🔵Base dev rel

With base flashblocks is Chainlink now faster?

How does one use it with viem? 

I haven't seen anything in chainlink docs

is it really just using the preconf RPC Url ? because then chainlink is still in block n+2 aka 6s delay minimum

Full-time dev, part-time debugger of my own bad decisions. Still lovely, allegedly!

i was reading that there is also a websocket connection to get push when something changed: https://docs.base.org/base-chain/flashblocks/apps

That’s my understanding too so I’d save myself maybe 1-2s on the VRF which is cool but not fast enough

My understanding it checks just the pending block and return then already containing flashblocks.

So when doing an eth_call instead of latest to pending block

Building /indexing; love your data again. Probably also running 🏃‍♀️

Got it so that helps a bit then. Cc @patryk

I haven't tried it, but practically speaking I think you could use something like viem to ask for the tx receipt and get it back prior to the tx landing in the next block. *At best* with Chainlink vrf this would cut the final block time by 2s - 200ms -- so ~4.2s vs 6s

Yeah... afaik, flashblocks is a fancy way of saying the tx will be extremely likely to land in the next block

More of a mempool optimization than a functional difference that will be felt by app devs for the foreseeable future

i think you just use `blockTag: "pending"` everywhere

in the newer versions of viem, you can use the chain import for `basePreconf` / `baseSepoliaPreconf` and it should just work.
