Also, I feel like somebody ought to make this really clear since I see everybody talking about USDT-sol and USDC-sol; GYC (the vendor that sparked this convo) doesn't take either of those, or at least they didn't last I checked. I don't remember if it's Tron or ETH or what, but it's not anything on SOL. They said awhile back that they were thinking of it because people who like do to the PYUSD-to-USDT thing on Exodus with Jupiter for like a few pennies of fees begged for it, but I haven't heard that they got around to it.
Just mentioning it because I'd hate to see anybody get all excited if that's who they're tryna buy from and then go "ope" when it's a no-go.
