# Tools ### Web2 ### Web3 **Avatar Marketplace (Beta)**\ [**https://marketplace.rcax.io**](https://marketplace.rcax.io) A marketplace completely centered around Reddit Collectible Avatars. $RCAX sales are exempt from service fees. Any other tokens pay a 1% fee that will be converted into $RCAX. **Random Avatar Swap** \ [**https://rcax.io/dapps/randomavatarswap**](https://rcax.io/dapps/randomavatarswap) This dApp can be used to swap your Reddit Collectible Avatar with another random one from the dApp pool. The Avatars in the pool are provided by so called liquidity providers. The pools are separated by the release generation. So if you send a generation 1 Avatar, you will always get another generation 1 Avatar in return. The first swap is free. Any swap afterwards will cost a service fee in $RCAX which differs per Avatar. Liquidity providers will earn half of the service fee whenever one of their avatars is swapped. --- # 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.
