Ordinals Wallet is a Bitcoin wallet that supports Ordinals inscriptions. It allows users to receive, store, and view Ordinals in their wallets, with functionality for transferring, sending, inscribing, and buying and selling Ordinals. Ordinals are means of creating Bitcoin NFTs by attaching data such as images, videos, and more to an individual satoshi on the base Bitcoin blockchain. Unlike their predecessors, ordinal NFTs don't exist on a separate layer from Bitcoin.
I also came to know about this wallet but I think you should avoid from these kind of wallets. Because these kind of hot wallets can scam anytime. Your funds are yours so you should avoid. And I will recommend to use cold wallet to store Bitcoin. By the way this is a new thing about NFTs on Bitcoin Blockchain. And this can be a trap too. So be careful.
