Aster is set to commence its fifth airdrop phase, named "Crystal," on December 22, 2025. This phase, which will last for six weeks until February 1, 2026, is the smallest of the five phases, distributing 1.2% of the total supply, equivalent to approximately 96 million ASTER tokens. The airdrop aims to enforce stricter supply discipline in preparation for the Aster Chain, following the official launch of its L1 mainnet. Participants will have the option of a three-month vesting period for their tokens.
