# Assets An asset, often referred to as a **token**, represents any artifact or specific tangible or intangible value recorded on the blockchain within the CoreLedger TEOS platform. Assets can be measurable if there is a need to operate with the units of the asset, for example, steel, man-hours or currencies. Some assets are not supposed to have any quantity, for example, an audit report or a document notarized on blockchain does not need quantity, then it needs only a unique digital id - the unique asset id in TEOS platform. Asset can be described in a very detailed way by filling its properties in TEOS platform with the help of TEOS API. These properties are categorized and placed within their categories (or sections) when forming a JSON structure to be saved in TEOS API. There are general and custom properties. TEOS user can link assets and unlink them, change asset with the help of amendments written to blockchain, exchange them with the help of supplies. All of these operations are possible after asset is created and written to blockchain. 📘 Learn more about Assets -[ link](https://app.gitbook.com/o/ZaeNizhnU47lCcTSk7wB/s/8Gkk33l0DIIchfRT86LP/~/changes/1/resources/using-the-teos-api/concepts/asset) --- # 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.
