Hey guys,

I created my first Dapp on Solana, it is unidouble.io. Basically everyone can post items and buy them like Amazon or Ebay.

If someone post an item, it can be bought by someone else and the buyer will put the delivery address. The delivery address is encrypted and stored on-chain, only the seller can decrypt the address.

The buyer can review the item and get a 1% cashback after the review. There is a 5% tax to stop people from buying and reviewing their own item. The money generated could be used later for charity or for the delivery of items.

I am working on it, right now it's a "minimal" version. It only works on Devnet and on desktop at the moment ( no mobile device yet sorry ).

I made a whitepaper. Everything is stored on chain right now, but the objective is to use IPFS and GenesysGo shadow drive to store items data.

Happy to hear what you guys think about it !
