About

PayPal and Google Cloud Web3 are excited to launch a bounty challenge powered by Stackup. 


We want to see what you can build using the free GCP Blockchain RPC alongside PayPal's multi-chain stablecoin PayPal USD (PYUSD).


Ideas to get started

  1. Integrate PYUSD stablecoin into a user-friendly Web3 payment flow that utilizes the Blockchain RPC for reliability and scalability.
  2. Create an analytics platform google colab notebook that monitors PYUSD transactions in real-time using data from GCP Blockchain RPC with historical Ethereum and Solana data on Google BigQuery - and export to Google Sheets
  3. Leverage GCP's free access to computationally expensive methods like debug_traceTransaction and trace_block to build a tool that provides detailed execution traces of PYUSD transactions.
  4. Build a fun user-friendly dashboard that explains network congestion related to PYUSD transactions and flows
  5. Analyze historical blockchain data to identify Maximally Extractable Value (MEV) events involving PYUSD.
  6. Build a dashboard similar to Ultra Sound Money but tailored to PYUSD. Provide interesting facts about PYUSD’s performance, adoption, and impact on the Ethereum network.


Details

GCP Blockchain RPC to read or write to Ethereum mainnet or testnet holesky. GCP RPC for the Ethereum mainnet is backed by clusters of Erigon archive nodes; Ethereum Holesky testnet is backed by clusters of Geth full nodes. What sets GCP's service apart is its offering of computationally expensive methods for free, making it stand out from other RPC providers. These methods include debug_traceTransaction, trace_block, trace_transaction, and more. By leveraging these powerful functions, you can perform deep blockchain analysis, complex transaction tracing, and advanced smart contract interactions without worrying about computational costs. 🔥


We know you have incredible ideas and we can’t wait to see what you build. Here are a few examples:


Example – On-Chain Insights

Imagine what you could uncover if you had free access to near real-time on-chain finance. You could create applications that retrieve and analyze blockchain data from the Ethereum mainnet in ways previously not feasible due to common API constraints. Think of building tools that allow users to monitor, visualize, or report on near real-time blockchain activity. For instance, analytics tools that track PYUSD smart contract calls for fund transfers, tools that analyze popular PYUSD pools on Uniswap, or PYUSD pools on Curve Finance. 


Example – Chain Interaction

With free access to advanced methods, you can optimize interactions, simulate transactions, or automate complex smart contract operations without worrying about computational costs. Consider creating applications that perform blockchain transactions or interact with smart contracts in innovative and efficient ways. For example, a tool that analyzes trace-level detail of PYUSD bridging events or complex multi-chain atomic swaps or fully featured dapps.

Submissions Requirements

There are 3 deliverables for this bounty challenge

  1. A GitHub repository containing the source code for your project. Please ensure your repository’s visibility is set to Public so that our judges can access your submission. It should have an open-source permissive license, preferably MIT or Apache 2.0.
  2. A comprehensive README file in the repository, with setup and usage instructions, and documentation explaining the problem your project solves and how it works.
  3. A video showing how your project works


Note that your project cannot be an exact copy of something that already exists. If you’re taking inspiration from an existing project and are making something that’s similar, you must state clearly in your documentation which project(s) you took reference from and how your project differs from that.


You may use any open-source libraries, frameworks, or programming languages.


Do take note that your submissions should adhere to the Project Rules and The Fresh Code Rule listed in the challenge rules.

Judging Criteria

Your project will be judged based on the following criteria:


Innovation and Creativity (40%)

  • Originality: How original is your project? Does it introduce new ideas or unique solutions in the blockchain space?
  • Cutting Edge Concepts: Does your project push the boundaries of what can be done with GCP's Blockchain RPC service and PYUSD? Are you exploring new possibilities enabled by the free access to computationally intensive methods while integrating PYUSD into real-world applications?


Pushing the Limits of What’s Possible (25%)

  • Effective Use of Computationally Expensive Methods: How effectively does your project leverage computationally expensive functions provided by GCP's Blockchain RPC service (e.g. debug_traceTransaction, trace_block, or trace_transaction) to analyse PYUSD transactions or interactions?
  • Demonstration of GCP's Advantages: Does your project showcase significant advantages provided by GCP's free access to these methods when working with PYUSD? Are you making use of functionalities that are typically cost-prohibitive with other providers?


Functionality and Relevance (20%)

  • Effective Utilization of GCP's Service and PYUSD: How effectively does your project utilize GCP's Blockchain RPC service in conjunction with PYUSD? Does it solve a real-world problem or enhance existing workflows in a meaningful way?
  • Relevance to Current Trends: Is your project relevant to current trends and needs in the blockchain community? Does it address pressing issues or offer valuable insights?


Accessibility (10%)

  • User-Friendliness:  How convenient and easy is it for others—users or developers—to use your product? Is it accessible regardless of the presence of a user interface?
  • Adoption Potential: Does your project have the potential for widespread adoption due to its accessibility and ease of integration?


Quality of Documentation (5%)

  • Clarity and Comprehensiveness: Is your documentation clear and comprehensive? Does it adequately describe the purpose, setup, and usage of your project?
  • Ease of Understanding: Does the documentation make it easy for others to understand and build upon your work?
