Explaining Smart Contracts

NFTs like on Objkt or FXHash are an example of a smart contract. The smart contract is used to set the rules for the NFT, like who the owner is, if it can be transferred, any royalties for the creator, etc. It enforces these rules whenever the NFT is sold or transferred.

DeFi apps like QuipuSwap Youves (referral link), SpicySwap and Plenty are another kind a smart contract.
