Crypto custodians are reporting elevated curiosity of their providers amid the rising frequency of so-called “$5 wrench assaults” on cryptocurrency merchants, buyers and undertaking leaders.
Within the final yr, a number of high-profile wrench assaults — bodily makes an attempt to steal somebody’s crypto — have focused distinguished buyers and enterprise executives within the blockchain business.
The crypto mantra of “not your keys, not your cash” has misplaced its energy amongst some buyers who worry 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 buyers, custodians are seeing a shift in choice 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 know-how officer of Bitcoin pockets Casa, printed a GitHub repository logging lots of of such incidents since 2014 — and people have been solely those reported within the information.
Within the final two to 3 years, as crypto adoption has sped up and turn out to be extra mainstream than ever, assaults have grown extra public and complex. In January 2025, the founding father of crypto pockets Ledger and his spouse, David and Amandine Balland, have been kidnapped, taken to separate places 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 fulfill with cryptocurrency professionals to debate the problem.
As concern over these assaults grows, crypto custodians are noticing an uptick in curiosity of their providers.
Emma Shi, over-the-counter and institutional gross sales director of HashKey, which gives custody and alternate providers, advised Cointelegraph, “We’re completely seeing rising retail anxiousness translate into significant inflows. Wealthier retail buyers are more and more approaching regulated custodians after high-profile instances just like the current Manhattan kidnapping, the place bodily coercion was used to entry non-public 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 buyers 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 buyers, the place holders “are actively in search of progressive options that get rid of that single level of failure to considerably elevate the bar for attacking.”
Already in 2023, a report from PricewaterhouseCoopers on the state of digital custody famous the problem of chilly wallets being liable to theft or loss. One resolution posited within the report was MPC or multisignature pockets choices.
Can custody providers cease wrench assaults?
Crypto self-custody, whereas boasting a brand new know-how, runs into the identical downside as treasure hoarders all through historical past — they have been weak to bodily assaults and theft till they may share that threat with a stronger and securer establishment like a financial institution. Robbing a financial institution is rather a lot more durable than robbing an individual.
In the identical vogue, crypto buyers at the moment are in search of to “elevate the price” of the $5 wrench assault. Wang mentioned that buyers want to “return to the elemental precept: making the price 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 current breaches at Coinbase and Bybit, even main regulated crypto companies are weak to worker misconduct and phishing.

Wang recommended that distributed custody, resembling MPC, “is a superior resolution as a result of it essentially solves the issue. The core precept of MPC is to make use of know-how to decentralize the only level of management and threat […] right into a ‘multiparty’ construction.”
In such a system, management doesn’t belong to anyone particular person, 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’t neglect the advantages of centralized custodians,” Wang mentioned. “Dependable safety measures carry higher assurance of protecting purchasers’ property secure, a well-recognized approach of doing issues for plenty of new crypto gamers.”
Centralized or decentralized, crypto buyers might nonetheless be in danger if the general public picture of crypto buyers is that they’re all strolling round with chilly wallets filled with Bitcoin.
Shi mentioned, “The notion of threat issues, too. Attackers usually assume holders retailer funds themselves, so public consciousness that extra crypto is held in custodial options might deter opportunistic assaults.”
Wrench assaults a “short-term downside” solved by adoption
Public notion is certainly altering. Retail buyers 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 mandatory for institutional buyers to become involved.
This regulatory shift has been good for the custody business as properly, because it “legitimizes skilled custody for on a regular basis buyers and is resulting in extra choices from not solely crypto-native corporations however conventional banks as properly,” mentioned Shi.
“We’re seeing crypto adoption speed up in areas with regulatory readability, which creates fully new custody issues for buyers who beforehand relied solely on self-custody options.”
Laws additionally elevate the stakes of wrench assaults, per Wang. Higher regulatory frameworks with extra jurisdictions “proactively setting sturdy rules” will “inevitably result in extra extreme legislation enforcement actions, which can considerably improve the price of such assaults and essentially curb such behaviors.”
“We see the bodily attacking as a brief problem,” Wang concluded.
The crypto business has developed by way of many phases, however the rise of wrench assaults on distinguished buyers and executives exhibits that it has but to succeed in the maturity of conventional monetary markets.
Within the meantime, executives aren’t solely shifting their property to centralized and decentralized custodians but additionally discovering muscle of their very own. Private safety corporations have additionally seen an uptick in curiosity from crypto’s elite to guard their houses and individuals.
