All Pulsechain wallets need to stop syncing blocks earlier than May 10, 2023 at 10:36 PM UTC. This was the exact time that Pulsechain forked from Ethereum, every txn before this is actually an Ethereum txn, not a Pulsechain txn.
This is causing really annoying situations where we have to delete dozens and dozens of txns (which will increase our the amount we have to pay Koinly for tax support unfairly) when we sync a wallet, and if we choose "sync wallet from beginning" in order to troubleshoot.
