Fetching new pool keys faster

[Stickmen1]

Hello,
Is there a way to get the pool keys information based on provided quoteMint and baseMint without having to load the whole raydium mainnnet.json since that takes a lot of time. Or for example to load the mainnet.json and update it real-time so that the pool keys are real-time updated?

Hi 👋

Yes. Check out https://github.com/raydium-io/raydium-sdk-V1-demo/blob/master/src/subNewAmmPool.ts

You can subscribe to AMM pool creation and generate the pool key structures much faster than pulling mainnet.json.

You'll need to refactor, but hopefully it points in the right direction.

I already saw that but when trying to implement it, this does not run (when running the function it just skips it)

rpcConnInfo.on("data", (data) => {
callback(data, programId)
});

I think it is possible the subscribe() to not function as it should

That code is assuming you're connected to a supported Geyser gRPC node.

You need to refactor it to work with a normal WS / HTTP node if you're not getting events.

Can you guide me a little bit more about how I am supposed to refactor it?

Hearing it's possible to fetch pool keys with 0 rpc calls and only using a token mint address, is there anything online/opensource that shows how to do this? Or is it just a false rumor

Did you manage to solve the problem @Stickmen1 . I have got to the same issue and could need some help.

Did you find a solution??

I was able to create a script that's an hybrid of SDK V1 and V2. It correctly constructs a ApiPoolInfoV4 instance of any pool using the Pool ID. (Gotten from the Raydium API v3)

Yes, unfortunately I cannot share due to competition issues and the time it took, but if you research hard enough you'll figure it out.
