Yes we do, but only limited to issues with the VPS like network down, offline, and etc. These issues rarely happen as we have nearly 0% of downtime during the past. Unfortunately, we DO NOT provide support for issues with your wallet and masternode. However, you could purchase our addon service for RM300/one time, to setup your masternode. It’s safe, as masternode don’t hold any coin. Coin will be in your local cold wallet.
