# **Liquify Indexer API Hackathon: Build the Future of On-Chain Data** ## **📅 Event Details** **Theme:** Unleash the Power of Custom Contract Indexing  **Format:** Virtual/Online  **Duration:** Q1-Q2 2026  **Registration:** [https://docs.google.com/forms/d/e/1FAIpQLSeq0v9dbBZFB83FnivwIoB0Mctj938kc7wamFVrdfRGnPl8cw/viewform?usp=header](https://docs.google.com/forms/d/e/1FAIpQLSeq0v9dbBZFB83FnivwIoB0Mctj938kc7wamFVrdfRGnPl8cw/viewform?usp=header) ## **🏆 $100,000 Total Prize Pool** We're challenging the sharpest developers to push the boundaries of Web3 data utilization using the high-speed, adaptable **Liquify Indexer API**. The $100,000 total prize pool will be distributed among the winners across three distinct categories, designed to maximize infrastructure support for future development. ### **Prize Structure** - **Cash Prize:** Each category winner will receive **$1,000 - $5,000 USD** in cash. - **Infrastructure Credits:** The remainder of the prize pool will be awarded as **Liquify RPC and Indexing Credits**, providing the winners with the critical infrastructure necessary to scale their projects. ## **🛠️ The Challenges (3 Winning Categories)** Participants must build a production-ready application that leverages the Liquify Indexer API’s ability to index custom smart contracts instantly and decode data into a database-ready format. ### **Challenge 1: Advanced Wallet Analysis Tool** **Goal:** Create a tool that rivals institutional-grade platforms (like Arkham or Dune) for deep, multi-wallet tracking.  **Focus:** Utilizing the API's custom indexing to track esoteric or newly launched contract interactions, providing unique alpha for users. ### **Challenge 2: Next-Gen Trading Tool with x402 Integration** **Goal:** Develop a trading dashboard or bot that integrates real-time index data with a trading execution layer.  **Focus:** **MANDATORY:** Must include live integration with the **x402** protocol/exchange (using its ABIs and smart contracts for indexing) to inform trading decisions instantly. ### **Challenge 3: Seamless DeFi Tax Reporting Tool** **Goal:** Build a robust, multi-chain/multi-contract application that simplifies the generation of regulatory-compliant tax reports for complex DeFi activities.  **Focus:** Demonstrate the API's ability to index and structure historical data from complex protocols (Lending, Yield Aggregators, AMMs) required for accurate financial reconciliation. ## **💡 Why Build with Liquify?** The Liquify Indexer API removes the core headache of Web3 development: **data synchronization delays.** Our unique architecture allows you to index a single, individual smart contract instantly, eliminating the need to re-sync entire databases common with legacy indexers. This unparalleled speed and customization mean you can focus 100% on building innovative user features. **Liquify's Core Advantage:** Faster indexing, infinitely adaptable to any smart contract your project needs. ## **➡️ How to Participate** 1. **Register:** Sign up at: [https://docs.google.com/forms/d/e/1FAIpQLSeq0v9dbBZFB83FnivwIoB0Mctj938kc7wamFVrdfRGnPl8cw/viewform?usp=header](https://docs.google.com/forms/d/e/1FAIpQLSeq0v9dbBZFB83FnivwIoB0Mctj938kc7wamFVrdfRGnPl8cw/viewform?usp=header) 2. **API Access:** All participants will receive a high-throughput API key for the duration of the hackathon. 3. **Build:** Choose a category and start building! 4. **Submit:** Projects must be submitted by the deadline, including code repository and a demo video. **Questions?** Email us at [support@liquify.io](mailto:support@liquify.io)
