TrustAid

TrustAid is a full-stack donation platform built for the Indian market, enabling donors to contribute to verified NGOs via UPI and card payments. Every donation is cryptographically logged on a blockchain ledger — creating a publicly verifiable, tamper-proof audit trail without requiring donors to hold or understand cryptocurrency.

Payments through UPI and cards. Trust through blockchain.

The Problem

Donation platforms in India suffer from a trust deficit. Donors have no way to independently verify that their money reached the NGO, and no guarantee that reported donation figures haven't been altered. Existing blockchain donation platforms solve this with crypto — but crypto adoption in India remains extremely low, creating a barrier for everyday donors.

The Solution

TrustAid separates the payment layer from the trust layer:

• Payment: Donors use UPI or cards — familiar, instant, widely adopted
• Trust: Every successful transaction is logged as an immutable record on the blockchain, generating a transaction hash the donor can verify independently at any time

This means any Indian with a UPI ID can donate and receive cryptographic proof of their contribution — no wallet, no crypto, no friction.

Key Features

• NGO registration and admin verification
• Campaign creation and browsing
• Donations via UPI and card payment gateway
• Automatic blockchain logging on donation confirmation
• Transaction hash returned to donor as proof of payment
• Donor dashboard with full donation history and blockchain references
• Admin panel for NGO and campaign oversight

Donation Flow

1. Donor selects a verified campaign
2. Initiates payment via UPI or card
3. On payment confirmation, backend stores the donation in MongoDB
4. Blockchain service logs an immutable transaction record
5. A transaction hash is generated and returned to the donor
6. Donor can verify the transaction independently via the hash

Tech Stack

Frontend

• React, JavaScript

Backend

• Node.js, Express.js

Database

• MongoDB

Blockchain

• Ethereum (testnet) via ethers.js

Architecture

TrustAid uses a modular backend structure:

• config/ – environment and DB configuration
• controllers/ – request handling per module
• middleware/ – auth, validation, error handling
• models/ – MongoDB schemas
• routes/ – REST API routes
• services/blockchain/ – handles transaction logging to chain

Core Modules

• Auth Service
• NGO Service
• Campaign Service
• Donation Service
• Blockchain Logging Service
• Admin Module

Database Schema (Core)

Users — user_id, name, email, password_hash, role, created_at
NGOs — ngo_id, user_id, org_name, reg_number, verification_status
Campaigns — campaign_id, ngo_id, title, goal_amount, raised_amount, deadline, status
Donations — donation_id, donor_id, campaign_id, amount, payment_method, payment_status, tx_hash, created_at
