10102:
Digital Inheritance Platform
A comprehensive codebase assessment, UI/UX overhaul and feature expansion for a Safe-based digital inheritance platform — including AI-assisted user guidance and smart contract enhancements for token management.
Stack
React, Redux, Solidity, Viem, Vercel AI SDK
Role
Assessment, Frontend & Contract Development
Scope
Architecture Review, UI/UX, AI Advisor, Token Whitelist, Auto-Swap
The Mission
“To create a secure, decentralised way for people to manage the inheritance and time-locked distribution of digital assets without relying on traditional intermediaries.”
Core Objectives
- Comprehensive quality assessment before platform scaling
- Friction-reduced UX for legacy and timelock contract setup
- AI-assisted user guidance that avoids false confidence in irreversible actions
- Extended token management via whitelist contracts and Uniswap auto-swap
The Challenge
The existing platform was functional but required a comprehensive quality assessment before scaling. A complex smart contract architecture — spanning Legacy contracts (multi-sig and EOA transfer) and Timelock contracts across multiple durations — demanded security review and scalability evaluation. User flows for configuring these contracts carried significant friction, and the roadmap included Bitcoin expansion via native TimeLocks. Upgradeable contracts via OpenZeppelin patterns required careful assessment before further development.
10102 operates in a high-trust environment where contract errors could result in permanent, irreversible loss of funds. Multiple contract types with multiple sub-types create significant UX complexity — compounded by the challenge of integrating an AI Advisor that must guide users confidently without creating false certainty around on-chain actions. Building token whitelist controls and Uniswap-integrated auto-swap mechanics within the existing Safe architecture required precision across every layer of the stack.
What We Built
AI Advisor Chatbot
A contextual AI assistant built with the Vercel AI SDK — guiding users through legacy and timelock configuration with precision, without overstating certainty on irreversible blockchain actions.
Token Whitelist Contract
A role-based access control smart contract enabling administrators to define allowable token sets within legacy and timelock flows — reducing surface area and operational risk.
UI/UX Overhaul & Quick-Action Presets
End-to-end redesign of legacy and timelock setup flows, with quick-action presets and deep-link navigation that reduce configuration friction for mainstream users.
Uniswap Auto-Swap Integration
Automatic token swap mechanics integrated directly into legacy and timelock contracts via Uniswap — enabling seamless asset conversion at the point of distribution.
Technical Architecture
Built on Safe (Gnosis Safe) with Legacy contracts supporting multi-sig and EOA transfer, and Timelock contracts spanning multiple durations. Smart contracts follow OpenZeppelin upgradeable patterns with role-based access control. The React/Redux frontend uses Viem for wallet integration on Ethereum Mainnet. The AI Advisor chatbot is powered by the Vercel AI SDK, and Uniswap V3 is integrated at the contract level for automatic token swap mechanics.
Real Impact.
Labrys delivered a senior-led assessment and full development cycle — hardening the platform's foundation, reducing user friction, and shipping AI-assisted and DeFi-integrated features that position 10102 for mainstream adoption.
