description: '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.'

  name: Lemon Cash Mini App SDK
  description: 'The Lemon Mini App SDK is the public developer contract for building
    a Mini App that runs inside the Lemon Cash mobile app. It is a TypeScript library,
    not an HTTP API: calls are passed to the native app over the React Native WebView
    postMessage bridge and every action is confirmed by the user in-app. The surface
    is six functions — authenticate (Sign-In with Ethereum, EIP-4361, with optional
    user claims), deposit and withdraw (move tokens between the Lemon wallet and the
    Mini App wallet), transferMoney (ARS and PEN payouts to whitelisted bank
    destinations), callSmartContract (single or batched contract calls with optional
    Permit2 approvals) and isLemonWebView (environment detection).'

    is transported over the in-app WebView bridge, not over HTTP.'
