<h1 class="heading-node">Build a Blockchain Indexing Platform on Helius</h1><h4 class="heading-node">Overview</h4>We are offering a bounty for the development of a blockchain indexing platform that enables developers to easily integrate and index blockchain data into a Postgres database. This platform should eliminate the complexity of running their own RPC, Geyser, Validator, or webhook infrastructure by leveraging Helius webhooks for seamless data indexing.<h4 class="heading-node">Core Functionality</h4>Postgres Database Integration:<ul class="list-node"><li>Users should be able to sign up and provide their Postgres database credentials.</li><li>The platform should allow users to specify what they want to index on the Solana blockchain.</li></ul>Customizable Data Indexing:<ul class="list-node"><li>Users can choose from predefined indexing categories, such as:<ul class="list-node"><li>Currently available bids on an NFT</li><li>Current prices of an NFT</li><li>Currently available tokens to borrow</li><li>The current price of a specific token on various platforms</li></ul></li><li>The platform should automatically start filling the user’s Postgres database with the selected data.</li></ul>Automated Blockchain Data Retrieval:<ul class="list-node"><li>Uses Helius webhooks to facilitate data indexing.</li><li>Removes the need for users to manage their own RPCs or Validators.</li><li>Ensures real-time and accurate data synchronization with Solana blockchain.</li></ul>User-Friendly Interface &amp; Experience:<ul class="list-node"><li>A simple and intuitive interface where users can provide their Postgres credentials and select data indexing options.</li><li>Automated backend process to handle data retrieval and indexing without manual intervention.</li><li>Clear status updates and logs for data synchronization progress.</li></ul><h4 class="heading-node">Technical Requirements</h4><ul class="list-node"><li>The more real world use cases covered the better.</li><li>Fully functional web-based platform that implements the above mechanics.</li><li>Secure integration with Postgres databases for seamless data storage.</li><li>Efficient use of Helius webhooks to index blockchain data in real time.</li><li>User authentication and database credential management.</li><li>Scalable backend to handle multiple users and data indexing requests.</li><li>Proper documentation outlining setup, functionality, and deployment instructions.</li><li>Basic documentation including function signatures and usage examples.</li><li>Demonstrate transaction signing and submission to Solana devnet.</li></ul><h4 class="heading-node">Deliverables</h4><ul class="list-node"><li>Test cases demonstrating functionality against Solana devnet.</li><li>README with setup instructions and dependency information.</li></ul><h4 class="heading-node">Evaluation Criteria</h4><ul class="list-node"><li>Code quality and organization.</li><li>Test coverage and robustness.</li><li>Documentation quality.</li><li>Performance benchmarks.</li></ul>
