# Madhouse Wallet

> The stablecoin off-ramp API built for scale

Madhouse Wallet helps users convert stablecoins to fiat through M-PESA, UPI, SEPA, and bank transfers.

Madhouse Wallet helps wallet providers and exchanges offer off-ramp functionality by converting stablecoins to local fiat through a single API. Partners can route payouts across M-PESA, UPI, SEPA, and bank transfers without building payment infrastructure. This allows integrators to launch off-ramp features quickly while users access fiat conversion across multiple currencies.
