The risk model for holding Bitcoin is shifting from losing keys to losing your life. Jonathan Pollock, speaking on What Bitcoin Did, argues that self-custody’s structural flaw is that keys can be coerced under duress - the so-called “wrench attack.” His proposed test for any industry solution is simple: it must protect coins even when an attacker knows your exact setup and you are fully compliant.
Pollock outlines BitKey’s “vault” approach: a 2-of-2 multisig requiring two biometric scans separated by a configurable time delay - days or weeks. The goal is to outlast an attacker’s patience. He cites data showing 99% of documented wrench attacks end within a week. Ironically, he suggests the ultimate escape hatch might be sending funds to a KYC exchange during an attack, moving the conflict from a knife point to an identity-verification process an attacker cannot win.
“If the secret is exportable on paper or metal, the hardware has failed to keep its primary secret.”

Concurrently, a parallel evolution is solving the problem of what happens when you can’t sign. On Citadel Dispatch, Ben Kaufman detailed Bitcoin Keeper’s use of Miniscript to create absolute time-locks for inheritance. Users can grant an heir a key that only activates after a preset date - say, two years. If the owner is alive, they simply refresh the lock with an on-chain transaction. If not, the protocol executes the transfer automatically, turning Bitcoin itself into a self-administering trust.
“An owner can give an heir a key that remains inert for a predetermined time, such as two years.”

Both developers are converging on a philosophy that user error and personal catastrophe are greater threats than state-level adversaries. Pollock calls seed phrases an “instant compromise” vector and a “DIY project” that burdens users with perfect execution. Kaufman’s Bitcoin Keeper acts as a graduation path, guiding users from mobile hot wallets up to geographically distributed multisig vaults. The aim is to make sophisticated security the default, not the frontier.
The tools are now arguing that the rational choice is shifting. For Pollock, it’s a question of which catastrophic failure you prefer: the political and business risk of an ETF, or the increasingly manageable technical risk of self-custody. For Kaufman, it’s about providing a bridge from pragmatic needs - like Tether for dollar stability - to sovereign Bitcoin savings. The shared goal is to make holding Bitcoin oneself not just an act of defiance, but one of simple, calculated safety.
