I am participating in URANIUM testnet airdrops they already have a page in Coinmarketcap and they are just finalizing their season 1, which will end in 4 days.
https://coinmarketcap.com/currencies/uranium3o8/ The current price of their physical Uranium is at $5. This is one RWA that's worth looking into. Do check out their airdrop too, you can find it on their homepage, this could be one of the frontrunners of RWA
