# Proposal Types

Every [Governance Proposal](https://docs.optswap.org/user-manual/governance/proposals) must be of a single Proposal Type. The parameters required for each Proposal Type differ based on the particular action required to be performed.

{% hint style="warning" %}
**All OptSwap Contracts are Non-Custodial.** While the proposal types below are versatile and quite powerful in terms of the actions that can be performed by the governance, it is just as important (if not more so) to understand what the governance **cannot** do. Specifically, the governance:

* **Cannot** access or withdraw user funds from any contracts (DEX/AMM/Staking/etc.,)
* **Cannot** change or manipulate user positions in the DEX or AMM contracts.
* **Cannot** change or reverse past transactions in any manner whatsoever.
* **Cannot** change the on-chain spot and settlement prices reported by the Meta Oracle.
