Fewer Than 40% of Crypto Investors Know About “Revoke,” Clabo Survey Finds 61.1% Effectively Unprotected

Clabo Inc. conducted a survey of 746 people with experience investing in crypto assets, focusing on awareness of “revoke” functions, or the cancellation of token approvals, and related security practices. The survey found that 61.1% of investors do not properly understand or execute revoke procedures, despite their importance as a defensive measure for protecting crypto assets. Only 12.7% said they both know about revoke and perform it regularly, showing that many investors fail to turn awareness into concrete action. The lack of security awareness was especially notable among investors with less than three years of experience and those who mainly manage assets through exchanges. The report also notes that awareness rises sharply once holdings exceed 100,000 yen, while hardware wallet users tend to show stronger defensive behavior. As hacking incidents involving smart contracts become more serious, old approval permissions granted to DApps can remain a continuing risk if they are not revoked. Many investors may believe their assets are safe simply because they are stored in a wallet, but lingering approvals can still expose those assets to theft. In the survey, 30.4% of respondents said they did not know about revoke, while 30.7% said they had only heard of it. Together, 61.1% are likely to lack effective protection. Another 23.1% said they know about revoke but have not taken action. Possible reasons include gas fees, the perceived difficulty of using revoke tools, and overconfidence that they will not become targets. By investment experience, the regular execution rate stayed around 8% among those with less than three years of experience. Among investors with three or more years of experience, however, the rate jumped to over 24%, revealing a clear divide. Still, even among veteran investors with more than five years in the market, 31.6% said they did not know about revoke, showing that long experience does not necessarily mean complete security literacy. Clabo argues that revoke should not be treated merely as a technical task, but as a routine part of crypto asset management. Regularly canceling unnecessary approvals should become as natural as locking one’s front door. The survey was conducted online on April 10, 2026, targeting men and women in Japan who currently invest in or have previously invested in crypto assets. The number of valid responses was 746. Clabo also states that the report is for informational purposes only and does not constitute investment solicitation or advice. Crypto asset investment involves high risk, and investment decisions should be made at one’s own responsibility.
