Use HIVE Keychain to safely tranfer your fees! Use the first option to transfer DEC from your Splinterlands wallet and the second one to transfer from your Hive-Engine wallet. Send the DEC from an account that you have also added with the $add function in discord.
Every day you receive an invoice from the SplinterRents Discord bot including a link to our website with the amount to pay. You can also send $status to the discord bot to request your current balance due.
