Hello,
You could delete all the transactions from the DB that involve LTC, but you do not really have to do this.
What you do need to do, is refresh the deposit addresses, and transfer the funds from CP to the new full node wallet.
Please see the FAQ under “I want to replace an adapter with another one.”
Then, send your LTC to a new address from the new wallet. Use an address that is not associated with any plugin users. Once you transfer the funds, the users will be able to withdraw their LTC from the new wallet, or deposit LTC to the new wallet.
If you absolutely insist on deleting all user balances, you can delete the LTC transactions:
DELETE FROM wp_wallets_txs WHERE symbol = 'LTC';
Don’t forget to backup your DB before you go deleting things 🙂
EDIT: I see now that the old balances are Litecoin testnet. You can delete these, but Litecoin testnet on CP has the symbol LTCT
, not LTC
so there is no chance of these being confused in the plugin.
