# Overview

Madhouse Wallet is a **stablecoin off-ramp API** built for B2B partners. Integrate once and give your users the ability to send USDC and receive local fiat in **85 currencies** across Africa, Asia, Europe, Latin America, the Middle East, and Oceania.

***

## How It Works

```
Your user sends USDC to a deposit address
            ↓
   Madhouse detects the deposit,
   converts at mid-market FX rate,
   and routes to recipient's bank
            ↓
 Recipient receives local fiat
 (bank account, M-PESA, UPI, SEPA, etc.)
```

1. **Create a recipient** — dynamic field validation per currency
2. **Get a quote** — mid-market FX, locked 5 minutes
3. **Submit a transfer** — receive a unique USDC deposit address
4. **Send USDC** — from any supported chain
5. **We do the rest** — conversion, routing, settlement
