Could i use custom geth rpc node as rpc node to sync the blockchain data?

i want to sync the data of new blockchan forked from etherum.so if there is a way to configure geth rpc node synced by mongodb,as i could add new blockchain.
thanks for the excellent project and the workers behind it!

I don’t know if it is possible to do that

i had found through the documents but nothing.

maybe I can utlize local dev chain server to resolve this problem.is that a good idea?

I don’t know, what you want to sync as blockchain data?

i want to sync heco(here https://www.hecochain.com/en-us/),which is the fork blockchain of ethereum ,so it use same the RPC geth with ethereum
