1. Ledgerly "From payments to accountability — redefining how institutional funds move, get audited, and reimbursed."

2. The Problem • Manual reimbursement processes are slow, error-prone, and non-transparent. • Missing receipts, approval delays, and fund misuse cause friction and loss of trust. • Academic and government projects lack real-time fund tracking and auditable trails.

3. The Solution Ledgerly Vouchers — a blockchain-based funding and reimbursement platform that: • Generates digital voucher tokens for every project expenditure. • Ensures real-time auditability and hierarchical approvals. • Automates reimbursement validation via smart contracts.

4. Evolution of the Idea Initial Concept: Blockchain payment middleware (email ↔ wallet transactions). Transition: Expanded to handle institutional workflows — mapping, auditing, and tokenized reimbursements. “ We evolved from a payment system to a funding accountability platform — because institutional finance needs more than just transactions; it needs trust.”

5. How It Works 1. Project Creation: Smart contract defines project fund rules, members, and spending limits. 2. Voucher Generation: When a team member pays for project expenses, a Ledgerly Token (LVT) is created. 3. Audit & Validation: Accounting or project head verifies the expense via blockchain record. 4. Reimbursement: Upon approval, stablecoin-backed LVT is redeemed for fiat equivalent. 5. Immutable Trail: Every transaction remains recorded for lifetime audits.

6. Tech Stack • Frontend: Flutter mobile app • Middleware: Node.js + Express • Database: MySQL (via PHP backend for mapping and logging) • Blockchain Layer: - Ethereum (Prototype phase) - Hyperledger Fabric (Target phase) • Token Model: Internal stablecoin (LVT) backed 1:1 by fiat funds in escrow • Encryption: In-house AES-based key protection for wallet data

7. Architecture Overview Flow Diagram: User → Expense Submission → Voucher Token Generation → Audit Contract → Approval → Fiat Reimbursement Modules: • Email–Wallet mapping (PHP) • Node.js middleware for payment and logging • Smart contracts for audit and approval workflow • Blockchain ledger for immutable transactions • Admin dashboard for fund visibility

8. Impact • Cuts reimbursement approval time from weeks to hours. • Enables tamper-proof fund auditing. • Prevents fund misuse via transparent ledgers. • Brings accountability and efficiency to project-based financing.

9. Use Cases • Academic Research Projects: Track and reimburse project expenses transparently. • Government Grants: Real-time fund disbursement and auditing. • CSR Funding: Ensure funds are used only for approved activities. • Startup Incubators: Automate milestone-based disbursements.

10. Future Roadmap • Integrate Hyperledger Fabric network for role-based access and governance. • Build Admin dashboard for accounting departments. • Develop AI-driven anomaly detection for expense validation. • API gateway for external ERP/finance integration.

11. Closing Line Ledgerly turns funding into a transparent, traceable, and trustworthy process — bridging the gap between accountability and innovation.
