IncDoor is a Web3-native donation protocol that brings transparency and accountability to real-world fundraising. With IncDoor, anyone can deploy an onchain donation campaign using a smart contract factory. Each campaign specifies a recipient address and a donation period. Funds collected are automatically transferred to the recipient when the campaign ends — no middlemen, no misuse.
This solves a common problem in real life: when people donate to a campaign (e.g., someone fundraising for medical help), there’s no guarantee the funds reach the intended recipient. IncDoor enforces this trust through smart contracts — donors can verify exactly how much was raised and where the money went, all onchain.
🧩 Project Logic Overview
🏗️ Factory Deployment:
Our platform has a Factory Contract that allows any user to deploy their own campaign contract using CREATE2 and a unique salt. Campaign creators can: Choose their own ERC20 token (e.g. USDC, DAI, etc.) for donations or any native token. Define campaign parameters like fundingGoal, holdingPeriodInSeconds, and recipient.
🎯 Campaign Contract Behavior: Once deployed: Anyone can deposit (donate) tokens to participate. Deposits are tracked, contributing toward a fundingGoal.
🔐 Withdrawal Logic: A special withdrawal function is exposed to anyone, allowing the transfer of all funds to the donation recipient once the campaign is over. The campaign is considered "over" in two cases: Time-based: The holding period has passed (block.timestamp >= startTimestamp + holdingPeriod). Goal-based: The fundingGoal has already been met.
