Project: ArcRemit - Cross-Border USDC Remittance on ARC

Overview

ArcRemit is a decentralized cross-border remittance dApp built on ARC Network, enabling instant USDC transfers with sub-second finality and 0.3% fees.

Repo: https://github.com/vominh1919/arcremit

Problem Solved

• Global remittance fees average 6.5% (World Bank 2024)
• Traditional transfers take 1-3 business days
• Vietnam alone receives $18B+/year in remittances with high friction

Why ARC is Perfect for This

• USDC as gas: Predictable fees in USD terms
• Sub-second finality: Money arrives in <1 second
• Low fees: 0.3% platform fee (20x cheaper than Western Union)
• EVM-compatible: Standard Solidity development

Features Built

Smart Contract (648 lines, 86 tests):

• Escrow-based remittance with claim/refund
• Batch remittances (send to multiple recipients in 1 tx)
• Recurring payment schedules
• Contact book with on-chain nicknames
• Referral system with fee discounts
• Remittance templates
• Emergency pause mechanism

Frontend (11 pages, 17 components):

• Next.js 14 + wagmi/viem + RainbowKit
• Dark glassmorphism design
• Vietnamese/English language toggle
• QR code for receiving payments
• Batch send, recurring payments, analytics dashboard
