The wrench attack problem has a technical solution. Jonathan Pollock told Danny Knowles that a 2-of-2 multisig vault with biometric scans and a configurable delay - days or weeks - makes kidnapping pointless. The aim is to outlast the attacker’s patience. BitKey’s system requires a second biometric scan to finalize a transaction, ensuring time is the ultimate defense.
"99% of documented attacks end within a week."

Pollock is dismantling the seed phrase standard. He sees the exportable secret as an instant compromise vector. He argues hardware must keep its primary secret internal, gated by biometrics like a fingerprint. BitKey uses a collaborative 2-of-3 setup distributed between hardware, a phone app, and Block’s servers. This architecture shifts the burden from perfect user execution to fault-tolerant system design.
Miniscript solves the inheritance flaw. On Citadel Dispatch, Ben Kaufman detailed using absolute time locks to create self-executing trusts. An owner gives an heir a key inert for a predetermined period, like two years. If the owner doesn’t refresh the lock with an on-chain transaction, the heir’s key activates automatically. Kaufman said this removes the need for an attorney or a central vault.
"This system relies on absolute time locks. It essentially turns the Bitcoin protocol into a trust that executes itself based on time."

The industry consensus is clear. Technical risk from self-sabotage is dropping below the political risk of centralized custody. Tools like Bitcoin Keeper guide users from mobile hot wallets to geographically distributed multisig. The progression makes self-custody a graduated path rather than a leap. Kaufman also integrated Tether on Tron, viewing stablecoins as a pragmatic gateway for users in failing currency regimes.
The decision now is which catastrophic failure mode a holder prefers. Pollock frames it as a choice between trusting politicians or trusting yourself. With vaults, seedless recovery, and programmable inheritance, the tools are aligning with rational self-reliance.
