FundChain — Decentralized Crowdfunding Platform
FundChain is a full-stack decentralized crowdfunding protocol built on Ethereum. Unlike traditional platforms like Kickstarter, FundChain gives backers real power — they vote on how funds are spent, funds are released milestone by milestone, and refunds are automatic if a campaign goal isn't reached. No middleman. No trust required.
The core insight: crowdfunding fails when backers have no control after donating. FundChain solves this with on-chain DAO governance.
— 4 smart contracts in Solidity 0.8.20: FundChain V2, FundChainDAO, FundChainNFT, FundChainMultiToken
— DAO governance: backers vote on spending proposals with voting power proportional to donation amount
— Milestone-based fund release: campaign owners cannot withdraw all funds at once
— Multi-token donations: accept ETH, USDC, and USDT in one campaign
— NFT badges for donors: Bronze (0.01 ETH), Silver (0.05 ETH), Gold (0.10 ETH) — ERC-721
— IPFS image storage via Pinata for fully decentralized campaign media
— Analytics dashboard with real on-chain transaction data via Etherscan API
— Full Next.js 14 frontend with dark/light mode, mobile responsive, countdown timers

I created a Solana-focused crypto wallet app designed to make managing digital assets feel clearer, calmer, and more premium. The app lets users track their portfolio, view live market prices, swap tokens via Jupiter, and send or receive assets, with real-time data powered by Alchemy, CoinMarketCap, and Helius.
A big part of my process was using @mobbin for inspiration and UI research. I studied premium fintech patterns, interaction flows, and visual hierarchy, then translated those ideas into a product that feels polished, intuitive, and trustworthy.
Building it with @Anything made the process much faster and smoother, and the final result is fully responsive.
Really enjoyed this one 💛

Impressive work!!
Most people think a shadow is just a shadow.
Study a real sundial: the shadow isn't a drop shadow or a perspective projection. It has personality. It's alive in a way digital shadows never are.
time.connectio.com.au uses real astronomical calculations to track the sun's position relative to you. Latitude, longitude, altitude. Shadow direction, length, softness, and colour temperature all shift exactly as they would in real life.
The numerals have weight. The penumbra is properly soft. The whole piece breathes with the day/night cycle. Sunlight on your wall by day. Moonlight mode at night.
Cast it to a 4K display and it becomes a meditative object in your home.
I built this to explore beauty and truth in digital mediums. And partly because I'm a little unhinged when something captures my attention.
This is awesome
