Airdrop Mechanics
The STO airdrop is part of Binance’s HODLer Airdrops initiative, which distributes tokens to BNB holders based on snapshot averages. Snapshots are taken multiple times per hour during the eligibility window to determine average BNB balances in Simple Earn and On-Chain Yield products.
Eligible users can expect airdrops to be distributed at least one hour before spot trading opens.
To ensure fairness, Binance has implemented a BNB holding cap, limiting each user’s participation to a maximum of 4% of the total eligible pool.

Marketing Allocation
In addition to the initial airdrop, Binance has reserved another 15,000,000 STO tokens (1.5% of max supply) for future marketing initiatives, which are set to begin three months after the listing.
