KuCoin Consolidates Flexible Earn Products and Retires Hidden Order; Anniversary Campaign Is Separate
Three sources cover an Earn migration, Hidden Order retirement, and a high-threshold VIP promotion. This review separates their dates, interfaces, migration mechanics, and uncertainties without campaign instructions.
KuCoin says Simple Earn Flexible and Crypto Lending Pro stop accepting new subscriptions at 18:00 UTC+8 on July 29, 2026. Savings, existing Flexible positions, and Crypto Lending Pro holdings are then consolidated into the renamed Simple Earn Flexible at 18:00 UTC+8 on July 31, with existing holdings described as migrating automatically. A separate notice says Hidden Order will be retired on August 3 UTC across web, app, and API. Order requests containing hidden, iceberg, or visibleSize will be rejected, while related order history remains available for six months. The ninth-anniversary VIP event is an unrelated promotion with high trading thresholds and probability-based rewards and does not explain the product changes.
Key facts
- At 18:00 UTC+8 on July 29, Simple Earn Flexible and Crypto Lending Pro stop accepting new subscriptions, while Savings remains available until migration.
- KuCoin says existing products continue accruing rewards before migration; at 18:00 UTC+8 on July 31, Savings, existing Flexible positions, and Crypto Lending Pro holdings consolidate into Simple Earn Flexible.
- The Crypto Lending Pro entry point will be removed, and the notice says users need not manually move holdings, though asset-level status and updated terms still require review.
- Hidden Order is scheduled for retirement on August 3 UTC across Spot, Margin, Copy Trading, and Futures web interfaces, the app, and the API.
- App version 4.38 and later removes the Hidden Order interface; older versions may still display it but return an error on submission.
- The API will reject hidden, iceberg, and visibleSize parameters, query endpoints remain available, and relevant historical order records are retained for six months.
- The ninth-anniversary VIP promotion runs from July 24 at 00:00 through August 14 at 23:59 UTC with high volume thresholds and probability-based rewards.

Impact analysis
The Earn notice primarily changes product names, entry points, and the migration path for existing holdings. Automatic migration does not establish that asset-level rates, redemption timing, capacity, or risk remain unchanged. Hidden Order retirement has a direct interface and software-compatibility effect: older apps may retain a control that no longer works, and order creation with retired API parameters will be rejected. Integrators therefore need to verify their order-building paths before the deadline. Continued query access and six months of history do not mean creation endpoints still accept the old fields. The anniversary campaign's trading thresholds and random rewards are unrelated to these operational changes and are not evidence of product safety or value.
What the announcement does not say
The Earn notice lists many affected assets but does not give post-migration APR, capacity, redemption speed, or regional eligibility for each one in the same source. The Hidden Order notice does not provide update dates for every third-party SDK or terminal. Campaign capacity, drawing outcomes, and eligible regions depend on the final event page.
Risk notes
- Automatic migration does not mean rates, terms, capacity, or redemption conditions stay unchanged.
- Failing to remove retired API parameters before August 3 may cause new order requests to be rejected.
- A Hidden Order option remaining in an old app version does not mean the feature is still supported.
- The VIP event uses high trading thresholds and probability-based rewards; fees, spreads, and market risk may exceed reward value.
- This article provides no subscription, trading, API-order, or campaign-participation recommendation.
