# Special Deployments ## Confidential Attacks Some chains may support unique features not available on other EVM chains. For example, [Oasis Sapphire](https://oasisprotocol.org/sapphire) offers confidential transactions, which allow players to submit information on-chain in a decentralized way that remains hidden from other players. However, smart contracts can still execute logic based on this confidential state. A Dragobits deployment is underway to utilize this distinctive feature. The mechanics are as follows: Upon joining a battle, a player can submit one of three special attacks along with their Dragobit. This special attack, or “**Confidential Attack**”, will remain hidden from other players. When a player attacks a Dragobit, they must also select a special attack. --- # 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.
