<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.
