Websocket !!

[RostislavStoliarchuk]

I need help, I've been hammering for a week and I don't understand.

For example, there are 3 Websocket providers.

• getblock
• ankr
• quicknode

BSC only works from getblock.

The question is, what's wrong with others?

Their statistics work, they show requests but do not load the pools, the eternal load comes out. Why ?

same problem.

I think it's a problem in the code. Or rather, some narrow variables that have an orientation to a specific websocket. In any case, you need clarification from the main developer.

I'll tell you any news.

Hello! I ran into a problem with Websocket. Getblock works, but ankr, quicknode, alchemy don't. They issue status 200 and 413 on requests. What could be the problem?

where do you put the websocket url? in the frontend or in the settings you save in the store contract? and another question, do you put https or wss?
I am using alchemy and it does not indicate an error. btw i am doing it over mumbai testnet (polygon)

Hi guys, unfortunately, I don't have time to support this app at the moment...

The problem with the long loading of pools is that the application starts to listen for the IDOCreated event of the IDOFactory contract, and if you start listening from block 0, then the application will start checking every 1000 blocks, in turn, and will show pools only when syncing up with the latest block, so for this, you need to set fromBlock to the height of the factory creation to reduce IDOPools loading time.

In theory, the problem with some types of WS services is that they don't provide historical nodes to get info from blocks of historical data.

The solution to this problem can be to create a subgraph of the contract, which will map it on the side of the graph node, and the application will simply pull data from the API.

hello! Thanks for answering, I have the fromBlock parameter set. the question is whether to use an http or wss websocket and where. beyond the new solution. thank you and i hope you are well

[VitaliyShulik]

I'm alright, thanks.

You need to set the HTTP RPC node only in the networksInfo.js config in the app source code and set the WS RPC node only in the admin panel on the app client side.

So I have it configured correctly. it was to confirm. Thank you very much!! and I hope you can help us. When the launchpad starts working I will make a donation.
Thank you again.
