Binance has distributed millions of StakeStone (STO) tokens to users through its HODLer Airdrops program. The airdrop rewards users who subscribed their BNB to certain Binance Earn products during a specific period.
This event is part of Binance’s ongoing effort to reward BNB holders with early access to new projects. StakeStone is the 17th token to be featured through HODLer Airdrops, which offer free token rewards with no trading or staking activity required from the user.

How Users Earned the STO Airdrop by Holding BNB
To qualify for the STO airdrop, users needed to subscribe their BNB to Simple Earn (either Flexible or Locked) or On-Chain Yields products between April 27 at 00:00 UTC and April 29 at 23:59 UTC.
During this period, Binance took multiple snapshots of user balances each hour. It then used those snapshots to calculate the average BNB each user held. Based on that average, Binance distributed a share of 15,000,000 STO tokens across all eligible users.
No extra steps were needed. Tokens were automatically credited to each qualifying user’s Spot Wallet. The process required no manual claiming, no fees, and no action after subscribing.

What Is StakeStone (STO)?
StakeStone is a decentralized protocol that focuses on liquidity distribution across different blockchain networks. It aims to solve the problem of liquidity being stuck in separate blockchains by offering a way to move assets and earn yield across chains in a simple and efficient way.
StakeStone introduces several key products:
-
STONE is a yield-bearing version of ETH
-
SBTC and STONEBTC are liquid, cross-chain Bitcoin-based assets
-
LiquidityPad helps newer blockchains access liquidity faster
The project is designed to reduce the complexity of earning passive income in DeFi, and to help users and protocols access capital where it is needed most.
By supporting multiple blockchains and offering flexible staking tools, StakeStone plans to become a key player in what it calls the “omnichain liquidity layer” of decentralized finance.
