# Write Functions

{% hint style="success" %}
The [Carbon DeFi SDK](https://docs.carbondefi.xyz/developer-guides/carbon-defi-sdk) simplifies the process, and is highly recommended. 
{% endhint %}

This section will group and organize all `write` functions that can trigger transactions against the Carbon DeFi contract. 

Important to note that all information that is needed for all `write` functions is visible and available on-chain, however, it is **highly recommended** to use the [SDK](https://docs.carbondefi.xyz/developer-guides/carbon-defi-sdk) to simplify the interaction and data collection processes.
