Is it possible, to set up a new node using geth and subscripe to that node using web3js to save all transfers from the very beginning? Like could I scubribe to get "logs" events on a node that is currently syncing and newly setup using geth? I need all transfer events in a database and I have tried multiple ways to get this done which didnt work due to provider limitations and long taking pagination processes. This would be my last attempt doing it if possible.

  • you can't use a node until it syncs fully.

if there are lots of events, you need to query by block range, otherwise you will wait for hours without getting a response.

In golang this would look like:

filter := ethereum.FilterQuery{}
filter.FromBlock = big.NewInt(block_num_from)
filter.ToBlock = big.NewInt(block_num_to)
topics := make([]common.Hash,0,1)
signature := common.BytesToHash(event_signature)
topics = append(topics,signature)
filter.Topics= append(filter.Topics,topics)
filter.Addresses = nil 
logs,err := eclient.FilterLogs(context.Background(),filter)
if err!= nil {
    os.Exit(1)
}   

imports

"math/big"
"github.com/ethereum/go-ethereum/ethclient"
ethereum "github.com/ethereum/go-ethereum"
"github.com/ethereum/go-ethereum/common"
