PROBLEM

The Gap This Needed to Solve

Traditional crowdfunding platforms can restrict who can raise funds, what campaigns are allowed, and how users access donations.

SOLUTION

The System That Was Built

Funding Chain used smart contracts for fundraiser logic, smart wallets for users, MoonPay for fiat participation, and a backend DEX conversion flow to support contributions from major tokens while depositing the correct currency into the fundraiser contract.

SYSTEM BUILD

What Went Into the Platform

Smart Contract Fundraising

Fundraiser logic was powered by smart contracts instead of relying on a centralized platform as the source of control.

Smart Wallet + User Flow

Each user had a smart wallet, allowing the platform to support Web3 functionality while keeping the experience more approachable.

Fiat + Token Accessibility

MoonPay enabled fiat participation, while backend DEX conversion was designed to support major-token contributions into the required contract currency.

Decentralized User Experience

Designed to feel similar to popular crowdfunding platforms while using decentralized infrastructure under the hood.
