# Grand Vaults ![Similar interface, new engine!](/files/-MgYAeBiHwU5-5aSfdFx) Grand Vaults are the next version of the vault smart contract of Gangster Finance. They differ in only one small aspect, but they're a great step towards creating the larger ecosystem of Gangster Finance. Upon deposit and withdrawal, the 10% fee which is collected is broken into the following portions:\ \- 6% to the Drip Pool\ \- 2% to Instant Dividends\ \- 2% to the Buyback Fund The Buyback Fund is a special allocation which adds value to the Gangster Reserve contract. Gangster Reserve is a whitelist-guarded contract which holds tokens and value for later use within the Gangster Finance ecosystem. The buyback funds are swapped for a desired token via an AMM router contract (typically, this will be PancakeSwap), and sent directly to the Reserve contract. Anyone can trigger a buyback operation - the function is separate from any other call in the contract, so the cost of the swap and transfer is not a burden of any Gangster unwillingly. Note, there is no personal reward for triggering buybacks - it's a community-focused function and feature, ready to be built and expanded upon in the future. --- # 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.
