SandStorm hackathon idea list
Idea list from SandStorm Hackathon
Choosing what to build on Blockchain & Solana is always a hard choice for Builders. Luckily, SandStorm Hackathon already offered a categorized list of what to build.
(Key learnings & top picks from the event can be found in this amazing post)
The original list is long and you can find it on the site, I will try to filter ones that can inspire Builders to plan their next move:
DeFi
Derivatives decentralized exchanges
Orderbooks used for other NFTs or Lending Rates
Hybrid MMs for Orderbooks
High throughput Payment systems
SwitchBoard Oracle Integration
Build an insurance protocol that requires settlement using off-chain data such as weather affecting crops.

Build any form of money app such as Russian Roulette relying on verifiable randomness.

Building With OpenBook
New Market Making Scripts/Methodology that takes into consideration on-chain limitations
Charting or Analytics solutions
Integrating Derivatives such as Perpetuals or Options
Future of Work
On-Chain Bounty Boards
Universal Reputation Protocols (with potential for composability)
Talent-Recommendation Systems
DeFi for Freelancers
Tooling for Educational NFTs (collecting, showcasing, etc)
On-Chain Resume Tools
Decentralized Adjudication Tools for Freelancers

Automated defi protection protocol (auto-repay on Solend).
Automated dollar cost averaging protocol.
Automated yield harvesting protocol.
