# Custom DApp As part of the WELF token ecosystem, presale holders have access to a unique feature within our custom DApp, enabling them to manage their holdings with ease. This feature allows presale participants to submit sell orders directly through our DApp, facilitating efficient, secure transactions. #### How It Works * **Sell Order Submission:** Presale holders can submit sell orders through our dedicated DApp interface, specifically designed for ease of use. * **Automated Token Liquidation:** Upon submission, tokens are automatically liquidated by the system, handling the entire process seamlessly. * **Proceeds Distribution:** After liquidation, the resulting proceeds are automatically sent to the holder's wallet, ensuring prompt delivery and easy access to funds. --- # 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.
