# Fees

At Den creation, its creator sets the fees. All the **fees are immutable** except for the Partner fee, which can only be lowered afterward.

<table><thead><tr><th width="122">Fee</th><th width="81">Limit</th><th width="423">Description</th></tr></thead><tbody><tr><td>Wrap</td><td>≤99%</td><td>Fee on wrapping <code>TOKEN</code> into the Den (<code>brTOKEN</code>).</td></tr><tr><td>Unwrap</td><td>≤99%</td><td>Fee on unwrapping Den (<code>brTOKEN</code>) into the <code>TOKEN</code>.</td></tr><tr><td>Buy AMM</td><td>≤20%</td><td>Fee on buying Den (<code>brTOKEN</code>) tokens from LP.</td></tr><tr><td>Sell AMM</td><td>≤20%</td><td>Fee on selling Den (<code>brTOKEN</code>) tokens to LP.</td></tr><tr><td>Burn</td><td>≤70%</td><td>Fee on all above actions, which burns <code>brTOKEN</code>.</td></tr><tr><td>Partner</td><td>≤5%</td><td>Fee on top of other fees, after Burn fee.</td></tr><tr><td>Protocol</td><td>10%</td><td>Fee on top of other fees, after Burn fee.*</td></tr></tbody></table>

After the above fees are assessed, 10% of `ARBERA` buybacks ([growing-dens](https://docs.arbera.io/dens/growing-dens "mention")) will be used for Berachain's validator vote gauging and generating even more yield for staked Den LPs.

### Example

Let's take a look at **brARBERA** Den with `ARBERA` as its asset, and **brARBERA-HONEY LP** on Kodiak.

| Fee           | Value |
| ------------- | ----- |
| Wrap / Unwrap | 1%    |
| Buy / Sell    | 0.5%  |
| Burn          | 40%   |
| Partner       | 0%    |
| Protocol      | 10%   |

As you can see, there is no partner fee, the wrapping/unwrapping fee is modest, and the buy/sell fees encourage bots to arb more frequently.
