They can only be withdrawn in the case of a buyout auction or if a user has accumulated 100% of the total supply of the token. This is to make sure that there is no situation in which the NFT can be withdrawn from the platform unless through a planned withdraw. #### Buyout: Token holders have the ability to continuously vote on a reserve price. The weighted average of this vote decides on the price needed to initiate a buyout. Alongside the reserve price, a buyout is also limited by a minimum quorum of token voters. This quorum is set by governance. A buyout can happen when there is an external party who deposited ETH that is greater than or equal to the reserve price after a minimum percentage of token holders have voted on the reserve price. This will kick off an auction. At auction completion, the NFT will be withdrawn and fractional owners will be able to trade in their tokens for ETH. ## Governance: Token governance's primary focus is in creating safeguards for the system to allow for fractional owners to hold their tokens in peace. This is primarily through finding edge cases in the ownership models and working through different griefing vectors and then eliminating those through settings, variable caps and governance upgrades. Some examples here are capping curator fees, setting a minimum auction length or in serious cases kicking a curator from their role. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://fractional.gitbook.io/fractional/security.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
