I always assumed a simple on-ramp solution would be possible and the next logical step but I'm not a dev and don't know the legality behind it. Seems like Primal managed it somehow. Would be cool to learn more about that. I think in person fiat tips always work well. Dollar bill in the hat on the stage kinda thing. But digitally, seems like there's too much friction, and then we're back to zaps 😂
