OKX Extends SPK Reward Campaign for Spark USDC On-chain Earn Program

OKX has announced the extension of its SPK reward campaign for the Spark USDC On-chain Earn program, now scheduled to continue until 8:00 am UTC on December 10, 2025. The campaign, which initially began on August 4, 2025, allows participants to earn up to a 10% annual percentage rate (APR), combining the base APR with a 5.5% real-time SPK reward.

Campaign Details

The initiative is available through both the OKX app and website. Users can participate by navigating to the 'On-chain Earn' section, selecting USDC, and choosing Spark as the source of earnings. The platform has emphasized that there is no subscription limit, enabling users to maximize their potential earnings during the campaign period.

OKX has clarified that participation is limited to main accounts, with sub-accounts excluded from eligibility. Additionally, the campaign is subject to geographic restrictions, and users from certain regions may not be eligible to participate, as outlined in OKX's risk and compliance disclosure.

Reward Distribution and Conditions

Rewards from the campaign are distributed daily in the form of SPK to users' funding accounts. OKX retains the right to postpone reward issuance if necessary, citing reasons such as risk control checks. In certain cases, rewards may be converted into platform vouchers or USDT of equivalent value, particularly if jurisdictional restrictions apply.

The campaign rules specify that rewards may include non-stable coins, with the actual amount based on the USDT spot pair price at issuance. Furthermore, OKX reserves the right to amend campaign rules and eligibility conditions, with participants bound by any revised terms.

Legal Considerations

OKX advises that the campaign does not constitute investment advice and warns participants to consider their financial condition and risk tolerance before engaging. Crypto assets, including stablecoins, are subject to market volatility and significant risk.

Participants are responsible for any taxes and additional expenses related to rewards. OKX will monitor participant behavior to prevent cheating or fraudulent activities, reserving the right to disqualify users who violate terms or engage in prohibited actions.
