A2A tokens are used as an intermediary in every trade on STeX using A2A technology. The utility function of the token provides a tier system for commission discounts. A2A tokens will give users an opportunity to reduce their trading fees by up to 50% through paying commissions with it.

The discount is based on the amount of the commissions paid to the system and the length of time the token is held in the account.

From every commission paid to STeX, 70% of A2A are sold on the open market at current prices and become STeX's income. The remaining 30% are immediately transferred to the smart-contract known as A2A SHOP to be sold from that contract at the all-time high price, 0.1% higher than the previous sale from the contract. You can compare it to the BNB token (Binance).

I hope that clarifies it a bit more
