Blockchain for Secure Cross-Border Payments

Objective

To develop a blockchain-based payment system that enables fast, low-cost, and secure international money transfers by eliminating traditional banking intermediaries and leveraging decentralized ledger technology.

Key Features

Decentralized Ledger: Transparent and tamper-proof record of all transactions.

Real-Time Settlements: Near-instant confirmation and finality of cross-border transfers.

Multi-Currency Support: Handles currency conversion through stablecoins or native tokens.

Smart Contract Automation: Manages transfer conditions, escrow, and compliance checks.

Identity Verification: Optional KYC/AML to meet regulatory requirements.

Technologies Used

Blockchain Platforms: Ripple (XRP Ledger), Stellar, or Ethereum

Smart Contract Language: Solidity (Ethereum), or built-in scripting (Stellar/Ripple)

Stablecoins: USDC, USDT, or native CBDCs

Frontend: React.js or Angular

Backend: Node.js or Go

Wallet Integration: MetaMask, XUMM (for XRP), or custom wallets

Oracles: Chainlink for FX rate feeds and regulatory data

How It Works

User Registration: Sender and receiver set up wallets and optionally verify identity.

Transaction Initiation: Sender enters the amount, recipient’s wallet, and currency.

Smart Contract Handling: Contract locks funds and calculates conversion based on real-time FX data.

Network Validation: Nodes validate and record the transaction on the blockchain.

Instant Settlement: Funds are transferred to the recipient's wallet, often within seconds.

Audit Trail: The entire process is transparently recorded and viewable on-chain.

Benefits

Speed: Reduces transaction time from days to seconds.

Cost Efficiency: Minimizes fees by removing intermediaries.

Transparency: Public ledger ensures accountability and traceability.

Security: Cryptographic protocols protect against fraud and tampering.

Financial Inclusion: Enables access to global payments even without traditional bank accounts.
