The problem RapiMoni solves
Problem
Massive Underbanking: Over 1.4 billion adults globally lack access to formal banking services, especially in LATAM.
Fragmented Payment Infrastructure: High fees, volatile currencies, and limited local rails make digital commerce and cross-border remittances expensive.
No Credit Access: Underbanked consumers lack affordable, accessible credit products to smooth consumption or bridge cash-flow gaps.
Solution
RapiMoni tackles these challenges by combining:
- QR/URL-Based Payments (no app required): Merchants deploy dynamic on-chain invoices; customers pay in MXNe or USDC.
- Zero-Interest Microloans: One active loan per user, collateralized at 120% USDC, repaid over 1–6 months. Merchant fees fund the model—no interest for users.
- On-Chain Swaps: If a customer lacks local stablecoin, they can swap USDC→MXNe via Aerodrome pools.
- Lender Yield: 90% of microloan fees flow to liquidity providers (MXNe depositors); 10% to protocol treasury.
- Future Extensions: Idle USDC collateral can earn Aave yield, 50% of which could back a native MONI token for rewards and governance.

Challenges I ran into
- Implementing the new wagmi hooks while maintaining the proper states of the variables when updates were received.
- Getting an onchain price feed for MXN/USDC working on Base Sepolia.
- Testing with real MXNe in Base using Remix IDE because the token contract has no read/write functions exposed.
- Running he app in the in-app browser of Coinbase Wallet was giving me unexpected errors while running the same project in the actual web browser was working properly.
- When trying to make transactions in Base Mainnet I got several errors from the Coinbase Wallet saying that i needed to have ETH in Ethereum in order to proceed with the transactions, even though I had enough ETH in Base Mainnet.
