Currently it has none but if you really want to buy/sell a timemint, there are several steps or procedures you must do. If you want to sell it you must have 8888 days to initiate a smart contract for selling timemint.if you are the buyer you have just to wait someone who is willing to sell.
Actually a TM trade is something really difficult to do because the amount of 8888 day is prohibitive for small investors and furthermore there is not such amount in sell walls both in ED and in Livecoin...so this is difficult to achieve in short time without a price explosion.
If we add also the fact that in order to sell a TM the buyer has to provide days for the transaction, the operation is even more difficult.
Probably DAYs are still a little bit overpriced...
