What OKX launched
OKX has opened a Flash Earn Lite pool for Concrete's CT token. Users who subscribe BTC, ETH, OKB or CT share a reward pool of 1,000,000 CT, paid as an airdrop on top of the normal Simple Earn interest on the subscribed coins. OKX published the terms in its help center on 23 October 2026 and reminded users on X on 27 October that the pool is live in the app.
Flash Earn Lite is OKX's lighter version of Flash Earn, its stake-to-earn product that adds bonus airdrops on top of base yield, with a short list of curated subscription pools.
Dates and pools
The reward period runs from 28 October 2026 at 07:00 UTC to 3 November 2026 at 07:00 UTC. Subscriptions opened early, on 24 October at 07:00 UTC, but money placed before the start only earns Simple Earn interest; CT rewards begin accruing at the official start.
The pool is not split evenly. BTC subscribers share 450,000 CT, ETH subscribers 420,000 CT, OKB subscribers 80,000 CT and CT holders 50,000 CT. Minimums are 0.001 BTC, 0.01 ETH, 1 OKB or 27 CT.
Tiers, limits and eligibility
How much you can subscribe depends on your tier. Tier 1 is capped at 1 BTC, 100 ETH, 200 OKB or 47,000 CT; Tier 4 allows up to 30 BTC, 3,000 ETH, 10,000 OKB or 2,450,000 CT. OKX sets the tier from your 30-day average daily net assets, 30-day spot volume or 30-day futures volume. Tier 4 needs at least $2 million in assets, $10 million in spot volume or $50 million in futures volume. Your tier is shown on the Flash Earn Stake to Earn page.
Only identity-verified main accounts qualify. Sub-accounts and institutional users are excluded, ETH borrowed through Flexible Loan does not count, and users in some countries or regions cannot take part. You can redeem at any time, but rewards are calculated hourly, so redeemed funds earn nothing for that hour. After the campaign, CT goes back to your funding account within four hours and other assets stay in Simple Earn.
About CT
CT has traded on OKX's global spot market since 30 September 2026. OKX describes Concrete as an institutional-grade on-chain asset management platform.
Our take
For most users this is a low-effort add-on: you keep earning Simple Earn interest on BTC or ETH you already hold and pick up some CT on the side. OKX does not publish an expected yield, and the value of what you receive depends on the CT price when you sell, so treat any APR shown in the app as an estimate.
Check your tier and region in the app before moving funds, and remember the CT pool means holding CT itself, with its own price risk. The OKX code in the boxes on this page is a general trading-fee offer and is not tied to Flash Earn.
