[RFP] - Savings Circle Miniapp

[sodofi]

Collective Investment & Randomized Reward Mechanism for MiniPay and Farcaster

1. Project Overview & Background

The Celo Foundation seeks proposals to build a Savings Circle Miniapp designed for MiniPay Miniapps and Farcaster Miniapps. This social-finance product allows groups of users to pool funds over a 7-day epoch, invest the pooled capital during the cycle, and then randomly award the aggregate interest to a single participant at epoch’s end. The draw will be conducted via transparent on-chain logic to ensure fairness and trust.

2. Objectives & Goals (Why now?)

Boost financial inclusion by introducing a familiar, social savings mechanism adapted for Web3.
Drive engagement in MiniPay and Farcaster ecosystems with gamified finance primitives.
Provide trustless, transparent execution of pooling, investing, and randomized payouts on-chain.
Foster a new category of social DeFi miniapps that combine community participation with financial incentives.

3. Scope of Work & Deliverables

Vendors are expected to deliver:
Miniapp Frontends: User-friendly MiniPay and Farcaster miniapp interfaces for joining, contributing, and tracking pools.
Pooling Contracts: Smart contracts to securely pool funds in cUSD, cEUR, or other stablecoins.
Investment Logic: Integration with safe yield protocols (on Celo or partner ecosystems) to generate interest during each epoch.
Randomized Payout Mechanism: On-chain verifiable randomness (e.g., Chainlink VRF) to select the winning participant.
Transparency Features: Real-time dashboards showing pool size, yield earned, and verifiable draws.
Social Features: Invitations, notifications, and progress-sharing across MiniPay and Farcaster.
Testing & Documentation: Contracts fully audited, end-to-end tests, and developer documentation for further extensions.
