sUPRO, issued by Stablestocks Lab Limited, is a tokenized stock that gives onchain exposure to ProShares UltraPro S&P500, a U.S.-listed exchange-traded fund, with each token backed 1:1 by one underlying share held in custody with licensed brokers. [S1][S2]

sUPRO tracks the live market price of ProShares UltraPro S&P500 (sUPRO), and if the underlying issues a dividend or distribution and eligibility requirements are met, those economic rights pass through to the tokenholder, though voting rights remain with custodian holders. [S1][S2] Tokenholders may stake into StableVault to receive yield-bearing stStocks combining dividends with DeFi yields. [S3] A Service Fee of 0.1% of the transaction amount applies, alongside upstream broker and trading fees. [S4]

Stablestocks Lab Limited, brand StableStock, is incorporated in the British Virgin Islands and operates from Singapore. [S2][S5] It does not hold financial-services licenses and disclaims being a regulated entity, relying on broker-dealer partners holding an AFSL, a Hong Kong SFC Type 1 license, and U.S. MSB registration. [S5][S2][S6] An sToken is the tokenized representation of a real share; tokens are unregistered under the U.S. Securities Act and offered only to Qualified Investors through affiliated entities. [S5][S1] U.S. persons are barred and KYC and AML verification applies for leverage and IPO access. [S5][S4] Tokenholders may redeem and burn tokens at any time to retrieve the underlying share. [S1][S2]

sTokens are issued natively onchain on Bsc through a liquidity partnership with Native. [S1][S7] Tokens are minted when brokerage-held shares are deposited 1:1 and burned on redemption, with mint, burn, buy, and sell records recorded permanently onchain. [S1][S8] Stablecoin settlement in USDT and USDC funds purchases of real securities, and reserve coverage is published per asset and verified by weekly assurance reports. [S9][S8]
