# DNA DNA (Dynamic Nurture of Affection) is a fungible token that symbolizes an Alt's value and is the most important element of Alt.town as it serves as both a value and trading. Each Alt issues one million DNA with all transactions recorded on-chain. DNA is stored in a spending wallet within Alt.town and cannot be transferred between users or moved outside of Alt.town. DNA is categorized into Owned by Alt, Ecosystem, Community, and Pre-Sale, accounting for 30%, 40%, 20%, and 10% of the total supply, respectively. 100,000 of those DNA will be distributed through three rounds of pre-sales. Once the pre-sale ends, on-chain-based order-book trading begins, allowing users to freely buy and sell DNA among themselves. After the pre-sale ends, 90% of the sales revenue will be allocated to the Alt through a post-sale settlement. For detailed information about the pre-sale and order-book trading, please visit the Town page. When the contract between Alt and Alt.town terminates, DNA trading will cease, and any held DNA will be extinguished. Operation policies including the cessation of DNA trading adhere to the terms of service within the Alt.town platform. {% content-ref url="/pages/TE65rm8qM22ueQ0oNqwB" %} [DNA Structure](/alt.town-service/dna/dna-structure.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.
