# Circulation

90% of the AA tokens can only be released and distributed through a unique MQE mechanism. 

To date, A3S has conducted two rounds of MQE activities. The first round took place on Arbitrum, and the second round on zkSync Era. The details of the token releases for these two rounds are as follows:

| Rounds                                     | Token Distributed                               | % of Max Supply                              |
