Koya lets African diaspora send money home in seconds — without losing 10% # Koya — Send money home. Not fees. > *"Koya" means "to send" in Ewe, the language of Lomé, Togo.* Koya is a Solana-based remittance platform that lets the African diaspora send USDC to family members in West Africa **instantly** — at a fraction of what Western Union charges. Instead of routing money through slow, expensive bank rails, Koya settles on Solana in under a second, then uses a **local agent P2P system** for last-mile cash delivery. Agents are registered on-chain with fees capped at 2% by the smart contract — no agent can ever charge more, even if they wanted to. Built at a Solana hackathon by a developer from Lomé, Togo — this is a real problem experienced first-hand. --- ## Run locally ```bash cd koya npm install npm run dev # → localhost ``` > The app works without a wallet — mock data is shown automatically for demo. --- ## Screens | Route | Description | |-------|-------------| | `/` | Landing page with fee comparison | | `/send` | Send USDC flow (wallet required for live tx) | | `/receive` | Recipient picks up cash with 6-digit code | | `/agent` | Agent dashboard — confirm deliveries, earn USDC | --- ## Deploy to Vercel ```bash npm install -g vercel vercel --prod ``` One command. No configuration needed. --- ## Deploy smart contract to Devnet > Requires Rust + Anchor CLI installed ```bash cd presentateur anchor build anchor deploy --provider.cluster devnet # Copy program ID → update declare_id!() in lib.rs + PROGRAM_ID in lib/constants.ts ``` --- ## The last-mile agent system **The problem**: Recipients in Lomé, Togo don't have USDC wallets. They need cash. **How Koya solves it**: 1. **Diaspora** (Paris, New York, London) sends USDC via Solana → funds locked in escrow smart contract 2. **Recipient** receives a QR code + 6-digit pickup code via WhatsApp/SMS 3. **Local agent** (e.g. Kodjo at Akodessewa Market) scans the QR, hands over cash 4. **Agent** enters the code → smart contract verifies → releases USDC to agen …
