# Vault Vault is an important innovation and development in the DeFi field. Only MFET can be invested through Vault. Users can buy MFET with BNB or BUSD in their wallets. The MFET purchase process takes place on PancakeSwap. A 10% portion of the investment made is deducted. 4% of this deduction is instantly distributed to the users in the Vault according to their pool weights. 4% is kept for 50 days to be distributed to users. The remaining 2% locked on the contract is decided by a DAO structure voted by users with Vault investments every year. --- # 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.
