BetterFund: Crowdfunding Platform Powered by Ethereum Blockchain

BetterFund is a decentralized crowdfunding platform built on the Ethereum blockchain, designed to provide enhanced security, transparency, and global accessibility. The platform is live on the Rinkeby Test Network and can be accessed here.

Problem Statement and Solution

Crowdfunding has become a crucial method for raising funds, especially during crises like the COVID-19 pandemic. However, existing platforms have several limitations:

1. Security: Traditional platforms can be vulnerable to hacking despite encryption measures. Blockchain offers unparalleled security, as it has never been compromised.

2. Transparency and Anti-Fraud: Current platforms lack transparency regarding fund usage, leading to scams. Our platform ensures full transparency at every stage of the funding process to prevent misuse.

3. Global Contribution: Many platforms restrict contributions to specific countries. Using blockchain technology, BetterFund enables anyone in the world to contribute quickly and easily.

We were inspired by the CryptoRelief initiative, which raised nearly $1 billion for COVID relief in India through transparent and global crowdfunding.
