<h2 class="heading-node">About Superteam Ukraine</h2>We're part of Superteam, a global community of Solana builders. We help onboard new talent, run bounties, and support the Solana ecosystem in Ukraine. We're all about fostering growth and innovation in the Web3 space.<h2 class="heading-node">Mission</h2>Build a production-ready, universal Solana indexer that automatically adapts to any Anchor IDL.Level: Middle<h2 class="heading-node">Scope Detail</h2><ul class="list-node"><li>Dynamic Schema and Decoding:<ul class="list-node"><li>Automatically generate a database schema based on the provided IDL, without manual table descriptions.</li><li>Decode not only instructions but also the program's account states.</li></ul></li><li>Indexing Modes:<ul class="list-node"><li>Batch Mode: Process data within a specified slot range or from a list of signatures.</li><li>Real-time Mode: Subscribe to new transactions with a "cold start" capability. When launched, the indexer should first catch up on missed transactions (backfill from the last processed point) and then transition to real-time mode.</li></ul></li><li>Reliability:<ul class="list-node"><li>Exponential backoff: Implement increasing delays between RPC retries to avoid overwhelming the node.</li><li>Retry mechanism: For failed requests.</li><li>Graceful shutdown: Ensure correct termination without losing state or incomplete database writes.</li></ul></li><li>Advanced API:<ul class="list-node"><li>Filter by multiple parameters simultaneously.</li><li>Aggregation, e.g., the number of calls for a specific instruction over a period.</li><li>Basic program statistics.</li></ul></li><li>Infrastructure:<ul class="list-node"><li>Docker Compose with all dependencies (start with a single command).</li><li>Configuration via environment variables.</li><li>Structured logging.</li></ul></li><li>Tech Stack: Choose either TypeScript or Rust. Participants can expand or simplify functionality, but all core requirements must be met.</li></ul><h2 class="heading-node">Submission Requirements</h2><ul class="list-node"><li>A public GitHub repository with a comprehensive README, including:<ul class="list-node"><li>Architectural overview.</li><li>Setup and running instructions.</li><li>Examples of API queries.</li><li>Explanation of key architectural decisions and trade-offs.</li></ul></li><li>A Twitter thread detailing your experience: what you built, how you tackled technical challenges, and the trade-offs you made and why.</li><li>Must be in English.</li></ul><h2 class="heading-node">Judging Criteria</h2><ul class="list-node"><li>Dynamic schema generation and account decoding.</li><li>Real-time mode with cold start functionality.</li><li>Reliability features (exponential backoff, retry mechanisms, graceful shutdown).</li><li>Advanced API capabilities, including aggregation and statistics.</li><li>Code quality, architecture, and presence of tests.</li><li>Clarity and completeness of the README, including explanations of architectural decisions and trade-offs.</li></ul><h2 class="heading-node">Reward Structure</h2><ul class="list-node"><li>1st Place: 500 USDG</li><li>2nd Place: 450 USDG</li><li>3rd Place: 250 USDG</li></ul>
