How to get data for charting? Moralis speedy nodes kinda slow

Moralis General
#1 
await myContract.getPastEvents('Transfer', {

            filter: { address: address}, // Using an array means OR: e.g. 20 or 23

            fromBlock:  13444120,

            toBlock: 'latest'

        }, function(error, events){ })

        .then(function(events){

            console.log("%j", events); // same results as the optional callback above

        });

Hello sirs, idk what to do from here. this is using bsc chain.

if I scan from 0, it crashes on me. plz help. I can get latest block for the entire chain, then reduce and look until I find a block for that address. I am new to web3.

My entire approach may be wrong. plz advise

on poo coin they use https://bsc-dataseed1.ninicoin.io/

if that address doesn’t have too many transfers, like less than 100k transfers, you could sync those transfers in your Moralis server db:
https://docs.moralis.io/moralis-server/automatic-transaction-sync/historical-transactions#sync-and-watch-address

or you could sync a specific event: https://docs.moralis.io/moralis-server/automatic-transaction-sync/smart-contract-events#sync-and-watch-contract-events

hmm ok so you’re saying these sites like dextools and poo coins are saving the results on their db?

#4

that is what I would expect them to do, at least to have a db from where to show the information

#5

ok… i found this, do u know how to call this function from the contract ABI? I am getting error no function found when trying to call

 const ll = myContract.events.Transfer().call()
        console.log(ll)

ppppp

#6

i think that function will give me block #, and I just call for each block ? idk cant even call that function says not found

#7

I don’t really understand what this syntax should do:

you can call a read only function that you have in the smart contract with .call syntax.

#8

ahhh that function records all transfer events from now onwards and emits it to client, so thats one problem solved. now i need to fetch past events without scanning entire block in n time for each request

#9

You can also sync past events in your Moralis server db, if there are not hundreds of thousands of events.
