Problem Statement
Cross-border remittances drain $45 billion/year in fees from people who can least afford it. The global average cost of sending $200 is 6.35% (World Bank Q4 2025). Banks charge 5-7%, take days, and require physical access. AI agents on stablecoin rails can eliminate this — Sarafu proves it with real on-chain swaps at oracle FX rates for $0.001.
Sarafu is an autonomous AI agent that handles cross-border remittances on Celo using Mento stablecoins. Users talk to it in natural language — 'Send $50 to Kenya' — and the agent reasons about intent, fetches real-time FX quotes from Mento on-chain oracles, gets confirmation, and executes swaps across 15+ currencies in under 2 seconds for less than $0.001 in fees. All inference is private via Venice AI with zero data retention and optional TEE attestation. The agent exposes remittance-as-a-service via x402 paid endpoints, and every swap is recorded on-chain via a deployed RemittanceSwap contract.
