OKX has officially introduced fees on its decentralized exchange (DEX) platform while simultaneously launching a rebate program to incentivize trading activity. The fee structure categorizes tokens into three groups: stablecoins and derivatives remain fee-free; mainstream tokens incur a 0.25% fee; and non-mainstream tokens, primarily meme coins, are charged a 0.85% fee. The rebate program offers up to a 30% commission rebate, with initial rebates starting at 10-20%, depending on the invitation code used. To qualify for the rebate, users must complete at least five trades on the OKX DEX and trade on at least 10 separate days between May 5 and August 20, 2025. Users can participate by updating their OKX app to the latest version and entering specific invitation codes such as "DAREN," "SUPEROGER," or "BUTONGREN." Additionally, OKX has launched a lottery for 350 official Anoma NFTs, accessible via the OKX platform and requiring a minimum of 0.005 ETH on the Base blockchain for participation. This event is part of the broader engagement strategy surrounding the OKX Web3 wallet and DEX ecosystem.
