Crypto custodians are reporting elevated curiosity of their companies amid the rising frequency of so-called “$5 wrench assaults” on cryptocurrency merchants, traders and challenge leaders.
Within the final 12 months, a number of high-profile wrench assaults — bodily makes an attempt to steal somebody’s crypto — have focused distinguished traders and enterprise executives within the blockchain business.
The crypto mantra of “not your keys, not your cash” has misplaced its energy amongst some traders who concern for his or her private security. Chilly wallets might supply full management over digital property, however additionally they current a single level of assault.
As crypto adoption grows, and wrench assaults stick with the proliferation of extra high-value crypto traders, custodians are seeing a shift in desire from self-custody to institutional management.
Crypto wrench assaults drive safety demand
Wrench assaults are nothing new. Jameson Lopp, a Bitcoin (BTC) advocate and chief expertise officer of Bitcoin pockets Casa, printed a GitHub repository logging lots of of such incidents since 2014 — and people had been solely those reported within the information.
Within the final two to 3 years, as crypto adoption has sped up and develop into extra mainstream than ever, assaults have grown extra public and complicated. In January 2025, the founding father of crypto pockets Ledger and his spouse, David and Amandine Balland, had been kidnapped, taken to separate areas and held at ransom.

Simply months later, the daughter of an alternate founder barely fought off attackers who tried to kidnap her in a van on the streets of Paris. Concern over the rise in assaults and their comparable strategies led French Inside Minister Bruno Retailleau to satisfy with cryptocurrency professionals to debate the problem.
As concern over these assaults grows, crypto custodians are noticing an uptick in curiosity of their companies.
Emma Shi, over-the-counter and institutional gross sales director of HashKey, which affords custody and alternate companies, advised Cointelegraph, “We’re completely seeing rising retail nervousness translate into significant inflows. Wealthier retail traders are more and more approaching regulated custodians after high-profile instances just like the latest Manhattan kidnapping, the place bodily coercion was used to entry personal keys.”
Shi mentioned HashKey’s custody enterprise has famous elevated curiosity in storage from “household places of work, crypto-native high-net-worth people and even these with nest eggs which might be massive sufficient to be weak to theft.”
Chilly wallets have lengthy been lauded by crypto advocates as a technique to give traders full management over their property and to maintain them maximally safe offline. Nevertheless, this single key additionally supplies a “single level of failure,” per Wade Wang, CEO of multiparty computation (MPC) crypto custody service Safeheron.
Wang mentioned that there’s a “flight to safety” amongst crypto traders, the place holders “are actively searching for progressive options that get rid of that single level of failure to considerably increase the bar for attacking.”
Already in 2023, a report from PricewaterhouseCoopers on the state of digital custody famous the problem of chilly wallets being vulnerable to theft or loss. One resolution posited within the report was MPC or multisignature pockets choices.
Can custody companies cease wrench assaults?
Crypto self-custody, whereas boasting a brand new expertise, runs into the identical downside as treasure hoarders all through historical past — they had been weak to bodily assaults and theft till they might share that threat with a stronger and securer establishment like a financial institution. Robbing a financial institution is loads more durable than robbing an individual.
In the identical vogue, crypto traders are actually searching for to “increase the fee” of the $5 wrench assault. Wang mentioned that traders want to “return to the elemental precept: making the fee for an attacker rise exponentially. For instance, when it prices $3 million to steal $10 million, the motivation for assault is misplaced.”
Third-party custody can obtain this and mitigate the issue of wrench assaults, including time-locks and layers of approval and shifting the goal from a person to the custodian’s staff.
“However it’s not an optimum resolution,” per Wang. Belief continues to be put in a single, centralized establishment and, as exemplified by the latest breaches at Coinbase and Bybit, even main regulated crypto companies are weak to worker misconduct and phishing.

Wang steered that distributed custody, corresponding to MPC, “is a superior resolution as a result of it basically solves the issue. The core precept of MPC is to make use of expertise to decentralize the only level of management and threat […] right into a ‘multiparty’ construction.”
In such a system, management doesn’t belong to anybody individual, and transferring funds requires advanced consensus protocols from a number of events.
Decentralized options might higher mirror the ethos of the blockchain business, however “we can not neglect the advantages of centralized custodians,” Wang mentioned. “Dependable safety measures carry higher assurance of preserving shoppers’ property secure, a well-known manner of doing issues for many new crypto gamers.”
Centralized or decentralized, crypto traders may nonetheless be in danger if the general public picture of crypto traders is that they’re all strolling round with chilly wallets stuffed with Bitcoin.
Shi mentioned, “The notion of threat issues, too. Attackers typically assume holders retailer funds themselves, so public consciousness that extra crypto is held in custodial options might deter opportunistic assaults.”
Wrench assaults a “momentary downside” solved by adoption
Public notion is certainly altering. Retail traders are more and more making crypto a part of their portfolio, based on a 2024 report from Ernst & Younger. New rules in massive monetary markets just like the EU and the US are creating the frameworks needed for institutional traders to get entangled.
This regulatory shift has been good for the custody business as nicely, because it “legitimizes skilled custody for on a regular basis traders and is resulting in extra choices from not solely crypto-native companies however conventional banks as nicely,” mentioned Shi.
“We’re seeing crypto adoption speed up in areas with regulatory readability, which creates solely new custody concerns for traders who beforehand relied solely on self-custody options.”
Rules additionally increase the stakes of wrench assaults, per Wang. Higher regulatory frameworks with extra jurisdictions “proactively setting sturdy rules” will “inevitably result in extra extreme regulation enforcement actions, which is able to considerably enhance the price of such assaults and basically curb such behaviors.”
“We see the bodily attacking as a brief problem,” Wang concluded.
The crypto business has developed by means of many phases, however the rise of wrench assaults on distinguished traders and executives reveals that it has but to achieve the maturity of conventional monetary markets.
Within the meantime, executives should not solely shifting their property to centralized and decentralized custodians but additionally discovering muscle of their very own. Private safety companies have additionally seen an uptick in curiosity from crypto’s elite to guard their properties and individuals.
