P2P Local Currency Transfers Between Lemon Users from Mini Apps

The Problem
The current SDK exposes transferMoney() to send ARS/PEN to external bank accounts, but does not allow transferring local currency directly between two Lemon users. This blocks any Mini App that requires person-to-person payments inside the Lemon ecosystem. To split a dinner bill, send money to a friend, pay a freelancer in ARS, or any P2P flow, the developer is forced to use transferMoney() to a bank account (requires manual whitelisting, money exits Lemon), use crypto as an intermediary (too many steps for the average user), or abandon the feature entirely. The Lemon app already supports transferring between contacts. That capability is simply not exposed in the SDK.

The Impact

This feature unlocks an entire category of Mini Apps that cannot be built today: apps involving local currency payments between people. Every group expense split becomes multiple transfers that stay within Lemon instead of going elsewhere. For developers it multiplies viable use cases, for users it removes friction, and for the ecosystem it means more engagement and retention without money leaving the platform.

What's Needed

A way for a Mini App to initiate a local currency transfer from the current user to another Lemon user, with native confirmation UI, and receive the result back.
