The problem Pixel Sky NFT Project solves

In times of war, millions want to express solidarity, but most Web3 platforms make supporting causes complex or impersonal. This project solves the problem by making it easy for anyone to upload a sky photo, mint a pixel-style NFT, and automatically donate ETH to Ukraine’s official wallet — all in one click.

It combines creative self-expression, crypto simplicity, and social impact in a way that lowers the barrier to action and amplifies decentralized giving.

Challenges I ran into

1. Users often forgot to switch MetaMask to the correct testnet (Base Sepolia), leading to transaction rejections. I added a clearer error message and instructions to guide them.

2. My smart contract initially rejected valid transactions due to a misconfigured msg.value. I corrected the ETH precision and used a constant for clarity.
