The Simple Agreement for Future Tokens (SAFT) is a legal agreement. You can think of it as resembling a forward or futures contract for an amount of ASK tokens: the seller (PERMISSION) sells the rights to tokens ahead of their release date to a buyer (you): the seller must then build the network that enables their use and deliver the tokens at the Network Launch. Half the number of ASK tokens purchased by SAFT investors will be delivered to them at the Network launch. The remainder will be delivered on the six-month anniversary of the Network Launch. When buying a SAFT, you own the right to receive tokens of the issuer on a future date subject to any limitations that are detailed in the SAFT itself.
