Ceramic is partnering with [Index Network](http://index.network/?ref=blog.ceramic.network) to challenge developers to build composable search use-cases between [Base](https://www.base.org/?ref=blog.ceramic.network) and other projects participating in [Base’s Onchain Summer](https://www.base.org/onchainsummer?ref=blog.ceramic.network). For example, those use-cases can include:

- Composability with commerce (Shopify)
- Composability with social graphs (Farcaster)
- Composability with on-chain (Zora, Nouns)

The bounty is officially hosted on [bountycaster](https://www.bountycaster.xyz/bounty/0x9c54d0ffa5b6d4792831eb3a190ed5198f8a3e15?ref=blog.ceramic.network).

### About the Index Network

Index is a discovery protocol, built on Ceramic, that eliminates the need for intermediaries when finding knowledge, products, and like-minded people through direct, composable discovery across the web. By leveraging Web3 and AI, Index offers an open layer for discovery as the first decentralized semantic index. It functions as a composable vector database with a user-centric perspective, enabling interaction with decentralized graphs like Ceramic Network for user-owned knowledge graphs and Farcaster for social discourse.

### About the bounty

For this bounty, developers have access to the [Base search engine](https://index.network/kjzl6kcym7w8yb2qvgewqavclp1l9r72ph31a6k6xqw91bas9wlh7fwmpph5uad?ref=blog.ceramic.network) created on Index Network. They can utilize this index and integrate it with other projects and tools participating in Base’s on-chain summer to innovate and enhance information discovery experiences. Additionally, using Farcaster Channel indexes as a data source can help create personalized applications.

TIP: Consider developing agents to facilitate user interactions with Index, such as notification agents, context subscription agents, or multi-agent scenarios that enable conversational participation.

### Prizes

A total prize pool of 2250 USDC will be distributed across top 3 best applications:

- First place: 1000 USDC
- Second place: 750 USDC
- Third place: 500 USDC
