FamTrust Vault

A mobile-first wallet + inheritance dApp that lets anyone lock digital assets into a time-based family trust on Monad. No lawyers, no centralized custodian, just a smart contract and a countdown. Problem: Crypto inheritance is broken. If something happens to you, your family usually has no idea your assets exist, let alone how to access them. Seed phrases get lost, private keys die with their owners, and "just tell your family the password" isn't a real estate plan. Traditional trusts are slow, expensive, and require lawyers most people can't afford. Solution: FamTrust Vault lets an owner deploy a personal FamilyTrust contract, add named beneficiaries with defined shares, and set a lock period in human units (seconds/minutes/hours/days. Beneficiaries can independently "unlock" their share once conditions are met, and claim it after the timer expires. directly from their own wallet, no owner involvement needed at claim time. Every function (deploy, add/remove beneficiary, adjust shares, withdraw, unlock, claim) is exposed through a native mobile UI built in Dioxus/Rust, with decoded revert reasons and explorer links so non-technical family members aren't staring at a hex string when something goes wrong. Private keys are stored using Android's app-private internal storage, sandboxed per-app by the OS and inaccessible to other applications — no cloud, no third-party custody.
