Project Description

Tontine: Empowering Savings, Transforming Lives Tontine is an innovative financial application built on MiniPay and Telegram, designed to revolutionize how savings are managed in emerging markets. By leveraging the age-old concept of tontine—a community-driven "shared piggy bank"—Tontine fosters collaboration, financial discipline, and access to opportunities for billions of people in regions like South Asia and Africa.

Why Tontine? In many emerging markets, traditional banking systems fail to address the financial challenges faced by communities. People struggle to save money consistently, and many are vulnerable to predatory practices like gambling or unsustainable debt. Tontine introduces a gamified yet disciplined approach to savings by pooling resources and offering incentives to participants.

Core Features: Incentivized Savings Pools:

Members contribute to a shared pool, making saving easier and more rewarding. Incentives are redistributed to encourage consistent participation. Community-Oriented Model:

Inspired by real-world tontine practices that emphasize trust and mutual aid. Helps communities collectively build financial stability. Telegram MiniApp Integration:

Seamlessly integrates with Telegram for easy access and management. Brings financial empowerment to users via familiar platforms. Targeting Emerging Markets:

Designed specifically for regions with limited access to traditional banking. Focuses on helping people overcome barriers to financial health. Vision: Tontine aims to transform the financial landscape for billions of people, enabling them to save more, share resources, and unlock opportunities in a sustainable, community-driven way.

With Tontine, saving isn't just a necessity—it's a shared journey toward a brighter financial future. 🌍💰✨

How it's Made

We created a mechanism to incentives saving with a yield lottery for emerging markets !

With our protocol, the user can stake cUSD into a staking pool contract that will then deposit it into a lending protocol (a fork of aave). The Pool will accrue interest until a draw has been made by an offchain operator (operated by us for now) and a random staker of the pool will be chosen to receive the entire reward (it is a weekly draw).

After the draw, the reward is compounded on the user's winner balance on the pool. At any point the user can unstake/withdraw his balance and use his cUSD to spend it, which means that the user never really "loses money" while having potential access to rewards of the entire pool, which incentives the user to stake (and save) his money with the app

We also created a system that allows recurring (monthly for now) deposit into the pool for the user. This is done throught a backend that is allowed to send metaTransactions for the wallet.
