Due to Minecraft's account management system, sellers need to do two things before selling a Hypixel Skyblock account. 1) The email on the Hypixel Skyblock account must be provided to the buyer or middleman. 2) The email must be on the Hypixel account for 30+ days. If either condition is not met, then the buyer should wait. If a Middleman transaction was created, our MM will cancel the transaction and instruct the seller to wait the full 30 days before starting another transaction...
