# Fee Policy

### OT reserves the right to change fee policy at any time

#### Fee Rates

A & B are non-stable tokens, S refers to non-OSD stable coin, below are swap scenarios between all types of tokens and their respective fee rates:

User(third party project) listed token -> OSD: 1%(can be changed upon project request)

OSD -> User listed token: 0.3% 

A(ETH/WBTC) -> OSD(OSD -> A): 0.3% 

A -> OSD -> B: 0.15% + 0.15% 

S -> OSD(OSD -> S): 0.06% 

S -> OSD -> S: 0.03% + 0.03% 

A -> OSD -> S: 0.3% + 0.03% 

S -> OSD -> A: 0.03% + 0.3%

For user/project listed token X, a higher fee rate is applied to incentivize liquidity provision.

X -> OSD: 1%

OSD -> X: 0.3%

* Select Pools:  75% of fee is sent back to liquidity pool, 25% collected as protocol revenue.
* Ordinary Pools: 60% goes to liquidity providers, 40% as protocol revenue pool.
* Stable coin swap(Stable coin to OSD trade & vice versa), 99% of swap fees are sent back to liquidity pools.

#### [Perps Funding Fee:](#perps-funding-fee)

## 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://onchaintrade.gitbook.io/ot/fee-policy.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.
