Wietse Wind on twitter reported that XLS20 went live. He noted:
So XLS20 (NFT’s on the XRPL) went live. Basically all (user facing) transactions signed with @XummWallet using our platform.
He also added:
We will add basic viewing when the ecosystem settled on standards. In the meantime, developers are very much invited to (like @PeerkatOfficial did) build NFT viewers and publish them in our xApp list, hopefully to the point where we can add an “NFT Viewer xApp catalog”.
