# Write Functions {% hint style="success" %} The [Carbon DeFi SDK](/developer-guides/carbon-defi-sdk.md) 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](/developer-guides/carbon-defi-sdk.md) to simplify the interaction and data collection processes. --- # Agent Instructions: 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.
