I didn’t even see Nexo listed anywhere but they can go in the maybe:
Will Nexo distribute the Songbird (SGB) tokens airdropped from Flare?
Response: I love to see engagement from the XRP community. We have a positive development for them that will be announced soon, so stay tuned. Now, about the airdrops, our team is leading discussions with Flare about how to best protect the interest of XRP holders. We will update you as soon as we know what the outcome of our talks with Flare is.
Assuming one's exchange doesn't participate, would you simply have to transfer to an exchange that does, then store as you wish after the drop? or locate a place that lists SB?
