Introducing Piggy

Gm guys, I’m Tony and I’m building Piggy and need your input validating the idea.

Piggy is a savings Mini App inside Nimiq Pay. Users deposit USDT into a personal vault, optionally earn yield via Aave on Polygon, borrow against their savings as collateral,

set up recurring deposits,

create goal-based savings targets, and join social savings challenges with streaks and leaderboards.

The problem it solves:

Users want simple ways to save stablecoins, earn yield, access liquidity without selling assets, hit specific goals, and stay consistent — without leaving their wallet or navigating complex DeFi.

Piggy delivers normie-friendly practical savings tools (yield + borrowing) combined with goal tracking and light social gamification in one clean app. Users get real utility and motivation without extra apps or friction.

How it uses Nimiq Pay:

Built as a native Mini App using the Nimiq Wallet SDK. It runs directly inside Nimiq Pay with seamless USDT deposits, withdrawals, and transactions on Polygon.

Leverages Nimiq Pay’s gas abstraction and wallet integration for a smooth, self-custodial experience.

Happy to hear your thoughts and questions . Thank you for your attention to this matter.
