Binance is launching a withdrawal lock to help deter crypto wrench attacks

Binance is launching a user-controlled withdrawal lock aimed at a threat the crypto industry has spent the past year reckoning with: physical coercion of holders, otherwise known as the so-called wrench attacks.

The feature, "Withdraw Protection," lets users freeze their own account against onchain withdrawals for one to seven days, the exchange said Monday. A stricter "lockdown" mode disables early unlocking entirely. Binance's press release says the lock cannot be overridden by the exchange.

In an interview with CoinDesk, the exchange’s Chief Security Officer Jimmy Su said the company built the feature in response to patterns it observed in the wild, including "withdrawals that are more risky or even coerced in some cases."

He pointed to users traveling to regions where being identifiable as a crypto holder carries physical risk.

"We are seeing a pattern where some of the users might go to more risky geographical locations," Su said. "They want to have this user-control layer where they can put in a restriction on withdrawals. In case anything happens, that would give them more time to recover."

Asked whether the feature was a defense against wrench attacks specifically, Su said that was one scenario, alongside cases in certain regions where bad actors actively work to identify crypto users for in-person targeting.

A policy lock

Binance's press release framed the un-overridable lock as a hard guarantee. Su clarified the mechanism is an internal policy.

“It's an internal policy for this particular feature. Our customer service agents are not able to override it,” Su told CoinDesk. “The goal is to address the irreversible transfer nature of crypto.. Unlike a fiat scenario where funds are withdrawn to a checking or bank account and there are ways to reverse the transaction, you can't do that with onchain crypto.”

The distinction matters. A cryptographic lock would be effectively immutable for the user's chosen period. A policy lock depends on Binance's continued enforcement, and on the absence of legal compulsion to lift it. Su said the feature does not block law enforcement orders.

"This does not prevent law enforcement from taking action on accounts," he said.

Why a delay is now worth offering

Withdrawal-delay features are not new. Coinbase has offered Vaults, with a 48-hour delay and email confirmation, for years. Kraken offers a similar Global Settings Lock.

The threat landscape has changed. According to data from CertiK and crypto researcher Jameson Lopp, verified physical coercion incidents against crypto holders rose 75% in 2025, reaching 72 confirmed cases. Assault-related incidents jumped 250%.
