# Bonding Curve Fees

### Overview

Bonding Curve fees are optional.

They can be set to zero globally or enabled selectively at the protocol level.

Mainnet values remain subject to protocol settings.

### Current public testnet reference

* Launch fee: **0.0001 TBNB**
* Auto-completion raise target: **0.0024 TBNB**
* Referral fee: **2%**
* Swap fee: **1%**
* Token owner fee: **0.1% (10% on 1% swap fee)**

### Fee types

#### Swap fee

Applied on bonding curve trades.

#### Launch fee

Applied when launching a bonding curve.

On testnet, the current public reference is **0.0001 TBNB**.

#### Finalization fee

Applied when a token is finalized before the bonding curve reaches the maximum amount.

#### Referral fee

Paid to a referrer when a launch or swap uses a referral link.

#### Token owner fee

A percentage of swap fees that goes directly to the token owner.

#### Liquidity add fee

When liquidity is added, a percentage of the token can be taken as a fee. This can be used for airdrops or other project purposes.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.feg.io/smartdefi-tm-platform/token-launchpad/sd-bonding-curve/bonding-curve-fees.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
