痛点分析
Pain Points Analysis
加密从业者的大部分资产都是加密货币，若发生意外将导致家庭整体损失较大
Crypto professionals hold most wealth in crypto; accidents cause major family losses
净资产集中于链上，缺少继承方案时风险集中释放。
Net worth concentrated on-chain; without inheritance, risk hits all at once.
家人不懂加密，不具备钱包保管能力，无法放心直接托管私钥
Families aren’t crypto-savvy; seed/wallet custody is unsafe to delegate
助记词、签名、链上权限复杂，直接给私钥易误用或泄露。
Seed phrases, signing, and on-chain permissions are complex and error-prone.
中心化托管存在单点信任与较高遗产税，违背去中心化特性
Centralized custody has single-point trust and high inheritance tax; anti-decentralization
依赖监管合规、冻结风险与手续费负担，缺乏链上透明与自控。
Regulatory reliance, freeze risks and fees; lacks on-chain transparency and self-sovereignty.
Family Key 方案介绍
Solution from Family Key

基于智能合约钱包和抽象账户

  • 1. 以 Safe 智能账户为载体，接入自研 Dead Man’s Switch 模块。
  • 2. 委托人定期重启心跳；心跳终止后受益人获得智能合约钱包权限。
  • 3. 受益人用邮箱/手机登录（Privy/Particle），零加密门槛，自动生成自托管钱包。
  • 4. 通过邀请、到期提醒（Email/SMS/Push）使产品人性化。

Solution

  • 1. Use Safe smart account as the base, integrating our Dead Man’s Switch module.
  • 2. Owner periodically refreshes heartbeat; once it stops, beneficiary gains smart wallet permissions.
  • 3. Beneficiary logs in via email/phone (Privy/Particle); zero crypto barrier; auto-generated self-custody wallet.
  • 4. Humanized experience with invites and expiry reminders (Email/SMS/Push).

核心接口与时序

  1. checkIn()：Owner 刷新心跳（同时清除 claimReadyAt）。
  2. startClaim()：Beneficiary 触发挑战期，设置 claimReadyAt。
  3. finalizeClaim()：Beneficiary 执行 Safe swapOwner 完成过户。
  4. status()：读取 lastCheckIn/heartbeatInterval/claimReadyAt.

APIs & Sequence

  1. checkIn(): Owner refresh heartbeat (also clears claimReadyAt).
  2. startClaim(): Beneficiary triggers challenge period and sets claimReadyAt.
  3. finalizeClaim(): Beneficiary performs Safe swapOwner to transfer ownership.
  4. status(): Read lastCheckIn/heartbeatInterval/claimReadyAt.
