OKX Launches Spark USDC on X Layer and Adjusts the Ethereum Product

OKX's Earn announcements dated September 25, 2026 include the launch of Spark USDC (X Layer) On-chain Earn and an announcement about delisting USDC on Spark (Ethereum) from Onchain Earn. The launch announcement does not show a specific publication time.

The new X Layer product was scheduled to begin at 03:00 UTC on September 25, or 11:00 Hong Kong time. The product uses a one-day redemption period, and OKX says rewards are distributed when users redeem.

How to access the product

On the OKX app, users can open Explore, select On-chain Earn, choose USDC, and then select Spark as the earnings source. On the website, the route is Grow, On-chain Earn, USDC, and Spark.

Ethereum product adjustment

OKX also listed a separate notice titled "USDC on Spark (Ethereum) delisting from Onchain Earn" on the same date. Users who hold this product should read the full delisting notice in the OKX Earn announcements before taking action, including the handling of existing subscriptions and the relevant redemption schedule.

Conditions and risks

OKX says the mechanism for each On-chain Earn product can differ. Users should check the minimum redemption amount, reward accrual start time, reward distribution time, principal redemption period, and expected annualized earnings before subscribing. OKX also says it charges a percentage of fees and does not assume responsibility for disputes, protocol hacks, project fraud, or other losses outside the product display and reward distribution service.
