Commission rebate
Commission rebate is another name for a fee rebate — the return of part of your paid trading commission. The phrase is the standard direct translation of the concept in Chinese-speaking markets (返佣).
Trading fees are historically called commissions, so "commission rebate" and "fee rebate" are the same mechanism under different vocabulary: a share of what you paid flows back to you, funded by the affiliate commission your activity generates.
The phrasing matters mainly for search and community language. Chinese-speaking trader communities use 返佣 (fǎnyōng, "returned commission") as the standard term, and English content aimed at those communities tends to render it as commission rebate; Korean communities similarly discuss the concept alongside "셀퍼럴" workarounds. Whatever the label, the honest evaluation criteria are unchanged — share of fees (not volume), per-exchange rates, settlement frequency and asset, and non-custodial delivery.
On loweef the mechanism behind every one of these names is the same product: 50–67% of trading fees returned daily in USDT, per-exchange rates published with verification dates. See the fee rebate entry for the full mechanics; this entry exists so the terminology maps cleanly.
