FamilyChain

Onboarding real families to Sui

Built by a father of six and lover of Sui. FamilyChain is the central hub which turns daily family life - messages, chores, rewards - into the on-chain ramp Web3 has been missing.

Overview

FamilyChain provides a persistent, user-friendly system where families communicate, manage schedules, assign tasks, and build incentive-driven accountability. Designed for long-term use, it enables families to stay connected, build shared culture, and own their data across generations—without relying on fragmented, short-lived platforms.

Problem

Families are fragmented and onboarding to Web3 is still hard

Modern families are fragmented across apps that are temporary, siloed, and not designed for long-term coordination or development. At the same time, Web3 adoption is limited by poor onboarding and a lack of meaningful, everyday use cases for non-crypto users.

Solution

One persistent system for daily family life

FamilyChain creates a single, persistent environment where families communicate, manage schedules, assign tasks, and incentivize growth. Users authenticate via zkLogin (Google OAuth), automatically receive a Sui wallet, and interact with blockchain-backed features without needing prior crypto knowledge.

The platform introduces Web3 through a familiar, high-frequency use case while enabling families to build accountability, productivity, and shared identity over time.

Why Sui

zkLogin: Seamless onboarding for non-crypto-native users (parents and children).
Walrus: Long-term, decentralized storage of family data and memories.
Move: Secure, upgradeable smart contracts for coordination and incentives.
Performance: Supports real-time interaction required for daily family use.

The Ask

Seeking $75,000 in non-dilutive funding

Funding will support mainnet launch, mobile development, and early user growth.

Where it goes: Mainnet deployment & security audit (~30%) · Mobile-first experience rebuild (~40%) · First 100 families onboarding & growth (~30%)

FamilyChain is capital-efficient and designed to operate with minimal infrastructure cost while maximizing real-world adoption impact.

Founder

I grew up in a suburb of Pittsburgh, Pennsylvania, and graduated with high distinction from Penn State with my bachelor's in Electrical Engineering. I started my career as a technologist at Georgia Tech Research Institute, working in Electronic Warfare supporting Air Force Special Operations Command. I pursued entrepreneurship for years, and currently work in Project Management with Georgia Power Corporation.

As a father of six, I built FamilyChain from the ground up to solve a real need in my own life: creating a system to help my children grow in discipline, learning, and resilience while preserving family connection and legacy over time.
