Abstract

We are witnessing a revolutionary tipping application on a live streaming platform, utilizing decentralized applications (DApps) and non-fungible token (NFT) technology on the opBNB chain. This application enhances interaction between viewers and live streamer, while elevating Web3 applications to new heights in real-life integration.

Introduction

Psyduck is a decentralized application for live streaming donations that not only integrates the web3 and web2 worlds, but also provides more donation types for live streaming viewers. It innovates the interaction between live streamer and viewers. Psyduck provides a website and Chrome extension for live streamer to create NFTs and donate the tip. Viewers can donate our cryptocurrency Psycoin or purchase live streamer's NFTs to support their favorite live streamer.
Blockchain technology provide:

• New ways to donate and interact: Psyduck uses ERC-20 and ERC-1155 for donations and live interaction.

• Provide Unique Rewards and Incentives: Blockchain enables the design of unique reward mechanisms for audience participation, such as cryptocurrency rewards, ranking systems, or NFTs proving their engagement.

• Enhance Community and Belonging: By creating a shared, decentralized community experience, blockchain helps audiences feel integral to the community, boosting their engagement and loyalty.

Our solution has the following features and advantages:

• Facilitates meaningful viewer-streamer connections via ERC-1155 token donations
• Offers creators new monetization methods
• Ensures transparency and security with blockchain technology
• Easy integration with a simple interface for users

Method

• Use opBNB to store token donation metadata
• Use Chrome Extension to build web connect plugin that interacts with opBNB blockchain
• Use Solidity to create smart contract
• Use React.js to build frontend
• Use Cloudflare_serverless to build serverless
