Lemon Cash

Lemon Cash Mini App SDK

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).
