[Avail DA](https://docs.availproject.org/docs/introduction-to-avail/avail-da) is a robust DA base layer for developers to spin up fast, cheap, and secure rollups. Build a project that utilizes Avail DA’s expandable blobspace meaningfully, or build a project that helps the developer/user experience and improves the Avail ecosystem. - Deploy an appchain for consumer applications. - Deploy a custom L2/L3 for innovative ZK, LLM, Robotics (check Nethermind bounties), etc. - Use [Stackr](https://www.stackrlabs.xyz/) to create a Micro-Rollup (application-specific chain) with Avail used as DA. - Use zkSync's ZK Stack to launch your own Rollup with Avail DA and launch any of your apps on it. - Use Arbitrum Orbit with Avail DA to deploy your appchain. - Use Polygon zkEVM/CDK powered by Avail to deploy your appchain.

Build anything that improves Avail's existing ecosystem and developer tooling. Some ideas include: - [Avail DA](https://docs.availproject.org/docs/introduction-to-avail/avail-da) efficiency cost calculator/visualizer: Compare the cost of submitting blobs on Avail, Ethereum, etc. - Developer Toolkits: CLI or script to easily deploy different rollups quickly. - Dashboards: Data visualization, Staking information, Light Client data, etc. - Validator Operations such as automated payout claiming - Multichain/Appchain explorers: Create an explorer that can fetch and view states of multiple rollups (defined by appID) running on Avail.

Avail allows anyone to spin up scalable and cheap rollups easily. Their team has created an Avail-powered OP Stack chain (EVM-compatible) for you to easily build and deploy your decentralized applications (dApps)! Deploy your dApp/contracts on this to be eligible for prizes. Most original, creative, and technically sound projects will have a chance at winning this bounty. - Contracts must be deployed and verified on the local [Blockscout Explorer](https://github.com/blockscout/blockscout). - Must document the contract addresses on GitHub README. - Projects will be judged based on their originality, creativity, and technical feasibility.
