AXIS

Set. Forget. Earn — on real US stock tokens, not only crypto pools. AXIS already ships gasless Google login yield on Arbitrum One (UXmaxx winner). For Open House we put US stock-token baskets under that same door: say “tech yes, oil no,” get a Robinhood Chain practice basket, and a weekly English note that shows the after-hours/weekend print next to Thursday’s close.
