Lemon Cash is a Latin American digital-money app operated in Argentina by Bay Treasure Caramel S.A., registered as a virtual asset service provider (PSAV N° 162) with the Comisión Nacional de Valores. Founded in 2019 by Marcelo Cavazzoli and Borja Martel Seward, Lemon combines a fiat wallet in pesos and dollars, crypto trading and custody, a Visa debit card with crypto cashback, stock investing and bill payment across Argentina, Peru, Brazil, Colombia, Chile, El Salvador and the wider region. Its public developer surface is the Lemon Mini App SDK: a TypeScript library that lets third-party web apps run inside the Lemon Cash mobile app, sign users in with Sign-In with Ethereum, request user claims, move crypto between the Lemon wallet and a Mini App wallet, transfer fiat to bank accounts, and call smart contracts on eleven mainnet and eleven testnet chains.
