RHUB charges a 3.3% fee on each trade: buy fees are burned, while sell fees are collected in ARB and used for RHUB buybacks, with the burned share increasing as RHUB falls below its 9.69M ARB ATH. At roughly 75% below its ATH (about 2.38M ARB in the image), 100% of sell fees are currently used to buy back and burn RHUB; the 164k ARB treasury is stated to remain untouched.
