Charged Particles

Charged Particles is an NFT protocol that allows you to take your NFT and give it a smart wallet that enables you to deposit other assets inside of that NFT – put other tokens like ERC-20 tokens, DeFi interest beading assets, or other non-fungible tokens. The original NFT becomes a basket of tokens that you can timelock. Even though you can transfer or sell the NFT, you or anyone else can’t take out the contents of it until the timelock expires.

Check out their dApp on Polygon or Ethereum and try to create a brand new asset class known as a Nested NFT or simpy buy and sell the existing ones on their marketplace.
