MEXC announced StakeStone’s STO spot and futures listings on April 3, 2025, alongside an Airdrop+ campaign that offered a combined 130,000 USDT in conditional reward pools. The campaign ended April 13, 2025, at 10:00 UTC; it is not an active offer. The announced pool was divided among deposit, spot-trading, futures-trading and referral activities, with eligibility rules and individual caps.
When did MEXC list STO?
MEXC said it listed StakeStone’s governance token, STO, on spot and futures markets on April 3, 2025. Its initial spot schedule set STO/USDT trading for 08:30 UTC and STO/USDC for 08:50 UTC. Deposits were already open, withdrawals were scheduled to open April 4 at 08:30 UTC, and Convert was scheduled to become available April 3 at 09:30 UTC. These are historical launch details, not confirmation that the pairs or features are available now. MEXC’s listing schedule and listing and campaign release describe the announcement.
What did the 130,000 USDT Airdrop+ campaign include?
MEXC’s campaign ran from April 3, 2025, at 06:00 UTC through April 13, 2025, at 10:00 UTC. The 130,000 USDT was the total across four reward pools—not a guaranteed payment to each participant. Rewards depended on the activity, eligibility, ranking, caps and event-period terms.
| Campaign activity | Pool | Published requirements and limits |
|---|---|---|
| Deposit event | 50,000 USDT | For new users and existing users whose cumulative deposits were below 100 USDT before the event began, subject to completing the applicable tasks. |
| Spot challenge | 20,000 USDT | Trade STO spot pairs with at least $2,000 in valid volume. Rewards were allocated according to each eligible user’s share of qualifying volume, capped at 2,000 USDT per user. Only spot trades with non-zero fees counted. |
| Futures challenge | 50,000 USDT | Qualifying perpetual-futures traders needed at least 20,000 USDT in total volume and had to rank among the top 2,000. Published rewards ranged from a 10 USDT minimum to a 5,000 USDT maximum per user. |
| Referral event | 10,000 USDT | An existing user could invite users with a referral code. After a new user completed any Event 1 task, the referrer could receive 20 USDT, subject to a 400 USDT cap and first-come, first-served terms. |
These figures and conditions come from MEXC’s April 3, 2025 campaign announcement. The notice does not make the pool amounts universal payouts: a participant’s eligibility and any reward depended on meeting the relevant terms during the campaign.
What is StakeStone and what does STO do?
MEXC described StakeStone as decentralized liquidity infrastructure intended to improve staking and liquidity distribution across blockchain networks. That is the exchange’s characterization, not an independent assessment of the protocol’s performance. MEXC’s release also described STONE and SBTC as tokenized versions of ETH and BTC, respectively, and mentioned LiquidityPad. Its roughly $600 million TVL figure was a dated 2025 press-release claim, not a current TVL measure.
StakeStone’s whitepaper describes a broader set of products: STONE as a yield-bearing token for ETH staking and restaking, and STONEUSD and STONEBTC as yield-bearing certificates for stablecoin and wrapped-BTC deposits involving custody and exchange accounts. The whitepaper says STONE may be redeemed immediately from a buffer pool when liquidity is sufficient; otherwise, redemption may require a withdrawal request and settlement. These are project descriptions, not independent validation of yield, liquidity, custody arrangements or safety. See the StakeStone documentation.
Rank #2
StakeStone documentation describes STO as its governance token and says users can convert STO into vote-escrowed veSTO. The project assigns veSTO governance, emissions-allocation, boosted-yield and bribe-reward functions. Its documentation states a total supply of 1,000,000,000 STO; that is not a circulating-supply figure or a valuation. StakeStone’s documentation sets out these token functions.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What risks should readers consider?
A past exchange listing or reward campaign is not evidence that a token is suitable for a personal-finance goal. MEXC warned that digital-asset prices can be highly volatile and may lead to significant or total losses. Its campaign notice also identified operational, technology and regulatory risks, as well as the possibility that technology or hacking issues could affect withdrawals. Yield-bearing product descriptions should not be read as guaranteed returns.

The dated listing notice does not establish current STO trading pairs, availability in a particular jurisdiction, or whether an individual user can access the token. Check MEXC’s current platform information and applicable local rules before relying on any present-day availability claim; do not treat the 2025 campaign announcement as a current trading recommendation.
