Privacy-Preserving Cross-Border Remittance Platform
Reducing remittance costs by 92% using Chainlink Runtime Environment, AI routing, and privacy-preserving technology.
Traditional cross-border remittances cost 6-7% in fees and take 2-5 days. This costs users $30 billion annually in unnecessary fees.
TrustBridge uses Chainlink Runtime Environment (CRE) to orchestrate:
- AI-powered routing - Finds cheapest cross-chain paths
- Real-time FX rates - Best rates from multiple sources
- Privacy-preserving KYC - Confidential compliance checks
- Risk assessment - Real-time fraud detection
- Smart contracts - Automated settlement
Result: 0.50% fees, 5-minute transfers, 92% cost savings
- Privacy Track ($16K) - Confidential HTTP + Private Transactions
- CRE & AI Track ($17K) - AI routing optimization
- Risk & Compliance ($16K) - Real-time risk scoring
- DeFi & Tokenization ($20K) - Smart contract infrastructure
- ✅ Real FX API - Live exchange rates from exchangerate-api.com
- ✅ AI Routing - Multi-chain path optimization
- ✅ Risk Engine - Blocks high-risk transactions
- ✅ Web3 Interface - Wallet connection & real transactions
- ✅ Smart Contracts - Deployed and tested (Foundry)
- ✅ 100% Test Coverage - All tests passing
