StableHub Rewards Carnival

Event Period: Starting Feb 6th, 2026 (end date to be announced)

Event Overview

The StableHub Rewards Carnival periodically features different stablecoins with ultra-high annualized rewards based on holdings. Each stablecoin has its dedicated promotional period, during which holding the featured stablecoin entitles users to:

• New-User Exclusive 100% Annualized Rewards: New users holding the featured stablecoin during its promotional period receive a $1,000 100% annualized reward quota on that stablecoin (valid for 7 days).

• 18% Annualized Rewards for All Users: The first 30,000 units of the featured stablecoin get 18% annualized rewards; amounts exceeding 30,000 get 3% or higher long-term annualized rewards (long-term rate varies by stablecoin; refer to the displayed APR on the event page).

Participation:

• Complete your identity verification.

• Deposit or purchase the stablecoin directly via StableHub and hold it in your OSL account.

• Each stablecoin’s 100% reward pool: $100,000. Rewards will be distributed on a first-come, first-served basis based on the order of users’ initial holdings of the designated stablecoin. Once you receive the 100% reward quota, you will be guaranteed that reward for 7 days.

• Each stablecoin’s 18% reward pool: $500,000, with rewards calculated and distributed daily based on holdings until the pool is fully allocated.

Please Note:

• New users are defined as those who have not made any deposits or trades on the OSL platform before the event begins (Feb 6th, 2026). Users who only completed registration or KYC prior to the event remain eligible.

• The holding amounts used for calculating rewards in 18% and 100% APR rewards do not overlap. If a user qualifies for both rewards simultaneously, they may have up to a maximum of 31,000 designated stablecoins in holdings eligible for enhanced rewards.

• The 100% APR has a total prize pool cap of $100,000. Rewards will be distributed on a first-come, first-served basis based on the order of users’ initial holdings of the designated stablecoin. Once you receive the 100% reward quota, you will be guaranteed that reward for 7 days.

2.Reward Calculation Mechanism

OSL Global will take periodic snapshots of eligible user holdings and total campaign holdings to calculate provisional rewards. All calculations, methodologies, and determinations of eligibility are final and at the sole discretion of OSL Global. Joining the campaign constitutes acceptance of this calculation method.

3.Reward Distribution

Accrued rewards, if any, will be deposited into the user's Funding Account at the intervals specified on the event page. OSL Global reserves the right to modify distribution timing, delay distributions for security, operational, or compliance reviews, or withhold rewards entirely in cases of suspected abuse (see Clause 9).

4.Asset Withdrawal

Held assets can be withdrawn anytime. While participants may generally request to withdraw eligible assets, such withdrawal is subject to processing times and may be delayed or suspended due to security concerns, market volatility, or technical issues. Rewards are not earned, and are forfeited, for any snapshot period during which a withdrawal request is pending or processed. Early withdrawal may result in the forfeiture of pending, uncredited rewards for the current calculation period.

5.Use of Client Assets

OSL Global will not hypothecate, lend, or otherwise encumber user-deposited assets for its own purposes without separate, explicit consent. However, users acknowledge that assets held by OSL Global are not segregated in an individual, name-on-account manner and may be part of omnibus wallets as part of standard operations.

6.Nature of Rewards

All rewards are strictly promotional, limited in quantity, and offered solely for the published event period. They are discretionary gestures by OSL Global, do not represent interest, a yield, or a return on investment, and do not create any ongoing entitlement or expectation for similar offerings in the future.

7.No Insurance or Guarantee

Participating assets and any rewards accrued are held as unsecured claims against OSL Global. They are not covered by any deposit insurance scheme, government guarantee, or investor compensation fund.Participants bear all risk of loss, including total loss, of both principal and rewards.
