PANews reported on October 31 that Aster announced an optimization of its S3 buyback and airdrop model: 50% of all S2 and S3 buybacks will be directly burned to reduce supply, while the remaining 50% will flow back to locked airdrop addresses to reduce circulation and reserve quotas for future airdrops. The official statement indicated that the buyback and burn mechanism will continue to iterate to support long-term value and sustainable growth.
