# Reviews TalentLayer ID’s build their reputation over time through receiving Reviews from counter-parties; people that have engaged in transactions as either a buyer or seller. A Review is an ERC 721 soulbound NFT that is associated with a TalentLayer ID. New Reputation NFTs are minted whenever a service is completed on TalentLayer. They include information about the service completed and a review from the other party. A TalentLayer ID can have an unlimited number of Reputation NFTs. Service buyers leave Reputation NFTs for service sellers and service sellers leave Reputation NFTs for service buyers - a mutual-review system. ## Learn More About The Tech Learn more about the technical side of reviews in our Technical Guide on the smart contract. {% content-ref url="/pages/T574CoS33xXCZuOuG2KN" %} [TalentLayerReview.sol](/technical-guides/lower-level-guides/smart-contracts/talentlayerreview.sol.md) {% endcontent-ref %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
