Only off-chain SLP can be used for crafting in-game. Thus, any SLP rewarded in-game or portaled into the game from a player’s wallet can be used for crafting. SLP that is on-chain as a token will not be able to be used for crafting.
As with Classic, SLP rewarded within the game can be claimed and minted on-chain into a token. The new mint delay system is structured so that you can only mint any rewarded SLP 7 days after it is obtained. However, during Season 0 no SLP will be allowed to be minted as we monitor the system. If any bugs, abuse, or exploits are found in SLP emissions, players may have SLP taken away before it can be minted.
By default, SLP will be usable for actions such as crafting in-game. However, a player can choose to turn off the ability for tokens to be used in-game via a checkbox at the bottom of the Account Settings in the Marketplace personal Dashboard.
