According to official news, OKX launched the Katana on-chain earning product based on the Morpho protocol on March 3, 2026 at 10:00 (UTC+8). Users can subscribe to the USDT on-chain earning product to earn on-chain rewards and participate in sharing a 65,000,000 Katana (KAT) airdrop. During the event, users only need to subscribe to at least 1 USDT to participate. The system will calculate the airdrop allocation weight based on the time-weighted holding size. Funds can be redeemed at any time, with a redemption period of 1 day. Early redemption will not affect the reward share already earned. How to participate: Open the OKX App—“Explore”—“On-Chain Earning”, select USDT and set the reward source to Morpho (Katana) to complete the subscription.
