BlockTease

💘 OnlyFans for web3 💌

Comment

Inspiration

Inspired by the dynamic yet problematic landscape of platforms like OnlyFans, BlockTease addresses critical issues that creators face in traditional Web2 models:

  • Delayed Payouts and High Fees: Many creators struggle with delayed payouts, exorbitant fees, and limited payment options, which significantly hinder their financial freedom and ability to reach a global audience. 🌍💸

  • Complex User Obligations and Agreements: The necessity to manage complex bank transfers, autopay setups, and resolve frequent bank server issues underscores the inefficiencies of old systems. 🏦🔄

  • Hidden Charges and Decreased Trust: As platforms grow and monitor engagement, they often change policies unexpectedly and impose hefty cuts, making creators vulnerable to sudden and unfavorable terms. 🔍📉

BlockTease is our response to these challenges—a decentralized platform where creators enjoy prompt payouts, minimal fees, and straightforward, transparent agreements.

How We Built It

image

We built BlockTease using a combination of technologies and best practices in both software development and blockchain integration. Here's a detailed breakdown of our tech stack and development process:

  • Smart Contracts: We implemented smart contracts for handling autopay subscriptions, cross-chain payments, and lucky draw rewards distribution. Solidity was used to write our contracts, ensuring security and scalability. 📜🔐

  • Chainlink: For real-time data feeds and decentralized oracle services, we integrated Chainlink. This includes using Chainlink VRF for our lucky draws, Chainlink Automation wrapping Chainlink Functions for subscription notifications, and Chainlink CCIP for cross-chain payments. 🔗🌐

  • Biconomy & Web3Auth: Biconomy's account abstraction SDK to facilitate txns bundling with gasless interactions, enhancing the user experience by removing the need to pay gas fees. Web3Auth, integrated with Biconomy, provides a streamlined login process that bridges Web2 and Web3 identities seamlessly. 🔑🌉

  • IPFS & Pinata: For decentralized storage, we utilized IPFS to host all digital content created by our users, ensuring that it remains accessible and censorship-resistant. Pinata is used to enhance IPFS file management and ensure reliable content pinning and retrieval. 🗃️📌

  • OpenAI & Chainlink Functions: We used paid OpenAI's API for dynamic NFT avatar creation, accessed through a paid subscription. These avatars are integrated seamlessly via Chainlink Functions, allowing on-the-fly creation and minting. 🎨🤖

  • Frontend and User Interface: Our frontend was developed using Next.js, providing a modern, responsive, and dynamic user interface. We focused on making the platform easy to navigate and visually appealing while integrating essential Web3 functionalities. 🖥️✨

  • Backend Integration: Our backend is powered by Node.js and Express, with MongoDB and GraphQL managing our data. This setup includes mapping token IDs to user wallets/emails, which is crucial for managing subscriptions via nodemailer. 🧠💻

  • Chainlink Functions with Nodemailer: For automated email notifications regarding subscription statuses and updates, we integrated nodemailer, ensuring that users stay informed about their subscriptions and interactions with creators. 📬🔔

  • Testing and Deployment: Testing of our smart contracts was performed using Hardhat to ensure security and functionality. For deployments, we utilized Render for backend services and Vercel for frontend hosting. 🚀

This combination of technologies and services provided a strong foundation for BlockTease, allowing us to deliver a powerful, efficient, and user-friendly platform.

Challenges We Ran Into

Developing BlockTease presented several technical and integration challenges that tested our ingenuity and skills. Here are some of the key obstacles we encountered:

  • 🌐 Dynamic Gas Estimation for Chainlink Functions: Adjusting gas estimates dynamically based on network congestion to optimize the execution of Chainlink functions was a complex task, requiring precise calculations and monitoring. 🔧

  • 🔗 Wrapping Chainlink Functions within Automation: Implementing Chainlink Functions within Automation involved creating dynamic string arguments utilized by the source script, where the conversion from address --> string and uint256 token IDs --> string in Solidity proved to be particularly tricky.🛠️

  • ⏱️ Backend Design Constraints: Designing the backend to ensure that the processing time for requests does not exceed the 9-second maximum timeout limit for Chainlink functions presented a significant challenge. This required efficient processing and optimization of backend operations.🖥️

  • 🔀 Web3Auth Chain Switching with Biconomy: Implementing Web3Auth to facilitate chain switching integrated with Biconomy Smart Accounts, allowing functions to trigger on different chains without hassle or address changes, was a complex but vital feature.🔄

  • 📦 Transaction Bundling and Gasless Paymasters: Integrating bundled transactions, such as approvals of USDC/ERC1155-NFTs and subscription contract calls, and coordinating these with gasless paymasters to fund the transactions, required detailed attention to transaction flows to ensure a seamless user experience. 💳

  • 🌙 Custom Binaries for Moonbeam Network: Integrating custom binaries of the Moonbeam network, including Moonbeam's Call Permit Precompile and Batch compile, to handle transaction bundling with gasless payments was a challenging yet rewarding process. 🛠️

  • 🎨 Seamless UI-UX Integration: Combining various components into a smooth and user-friendly interface was perhaps our biggest challenge, especially ensuring that the advanced functionalities did not complicate the user experience. 🖌️

These challenges pushed us to explore innovative solutions and adapt our strategies, ultimately leading to a more robust and versatile platform.
