Was your VexPolyCUB locked? I think I have to go open a support ticket because it won't unlock before the burn ends.
Seems like you don't have to unlock them after all. You can burn the vexPolyCUB tokens directly if you know their smart contract address. This is it: 0x472a65cA0D76a938925d8a373b793C99379ABd83

Ok. I am guessing I need to make sure to swap some LEO to pLEO and back for the form though. I'll do that tomorrow.
If you have pLEO or something else on Polygon you can swap to pLEO you don't need to wrap 3-5 LEO to pLEO. Remember there's a 1 LEO fee for wrapping. If it's cheaper in a different way, take it. I just swapped the minimum MATIC that I needed to get 1 pLEO to unwrap.
