加密资产私钥 multi-sig 应急恢复条款:M-of-N 阈值与遗嘱执行人衔接

一句话定义:加密资产私钥 multi-sig 应急恢复条款是在遗嘱 / 信托 / 数字资产托管协议里规定 —— 加密资产私钥通过 M-of-N 多签方案分散持有,任意 M 个 key holder 在指定触发条件(死亡证明 + 公证人确认 + 时间锁)满足后可联合执行恢复,形成"持有人去中心化 + 触发法律化 + 动作可追溯"的程序设计。

适用场景:加密资产价值占总资产 20%以上的高净值人 · 信托底层资产含 BTC / ETH / 稳定币 · 数字资产私募投资合伙人需要安排接班 · 跨境家庭中加密资产位于一国但继承人位于另一国 · 加密资产挖矿 / 抵押 / DeFi 协议参与所需的持续操作需要在主人事变后继续。

关键风险:key holder 集中(如全部交给家属)触发同时失能风险 · 触发条件模糊(如"在他人认为合适时")触发法律争议 · 签名机制依赖单一硬件 / 软件商 · 跨境 KYC 在死亡触发时拒签 · 私钥碎片物理灭失(保险柜 / U 盘损毁)· 加密货币交易所配合度低未提前签 letter of authority。

(d) Each key holder shall execute a Proof of Possession every six (6) months by signing a 0.0001 BTC (or equivalent) test transaction to a designated verification address. Failure to provide PoP for two consecutive cycles shall constitute deemed loss of the relevant key, and the Trustee shall convene a key replacement procedure under Clause 8.
(e) The Settlor maintains in a separate Secure Storage Document (held by [Independent Trust Company] in tamper-evident envelope) the following backup recovery information: (i) seed phrase for each individual signing key, encrypted with Shamir Secret Sharing 3-of-5; (ii) hardware wallet PIN codes; (iii) custodian KYC verification documents to facilitate eventual liquidation through a regulated exchange.
(f) Liquidation of Digital Assets, if any, shall be conducted through a regulated virtual asset service provider licensed in BVI / Cayman / Hong Kong / United States, with KYC documents pre-cleared with the relevant provider at the time of this Letter of Wishes.
(g) The Trustee shall maintain a CARF / DAC8 compatible reporting log of all key holder identities, PoP records, Trigger Event verifications, and resulting transfers, and shall include such records in annual reporting to the Settlor and the Primary Beneficiaries."
