# Mechanism for BBB

There is a separate smart contract that holds the allocated revenue for the BBB. When Takadao collects revenue through a smart contract call, the correct allocation will be transferred to the BBB smart contract automatically within the same transaction. The BBB smart contract will have a function call to perform the buyback and burn. The call to buyback and burn may only be triggered by an authorized wallet address through Chainlink based on the BBB schedule.

This transaction will:

* Buy a specified amount of TAKAs from the swap with a fixed slippage (0.5%). 
  * If the slippage cannot be met, the transaction will fail.
  * The specified amount will be based on the available funds.
* The purchased TAKAs will be burned using the token contract’s burn function.
* The amount spent to swap and the amount of tokens burned will be logged.

The BBB mechanism is controlled and maintained by Takadao with input from TAKA token holders through governance procedures in accordance with Takadao bylaws.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.takadao.io/takadao-docs/part-c.-takadao-the-company/10-the-takadao-token-taka/value-accrual-and-price-stability-sources-of-token-demand/buy-back-and-burn-bbb/mechanism-for-bbb.md?ask=<question>&goal=<endgoal>
```

`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.
