The attack allowed researchers to extract some chip secrets and bypass firmware signature checks.\n\nTropic Square disclosed a vulnerability in the TROPIC01 Secure Element chip used in Trezor Safe 7. It has been identified based on findings from the Ledger Donjon team's independent audit.Important: Your funds remain safe and secure. Trezor Safe 7 has not been hacked, and you…— Trezor (@Trezor) June 3, 2026\n\nTropic Square later found another way to use the same weakness. That method could expose another secret tied to PIN-related chip functions.\nTrezor says funds remain protected\nTrezor said users do not need to take action. The company said a compromise of TROPIC01 alone does not give access to a user’s PIN, wallet or funds.\n“Because the Trezor Safe 7 was built with multiple independent security layers, a vulnerability in TROPIC01 does not put user funds at risk,” Trezor CEO Matej Žák said.\nThe issue sits at the hardware level, so it cannot be fixed through a normal remote firmware update. Trezor and Tropic Square still chose public disclosure after reviewing Ledger Donjon’s findings.\nThe Safe 7 uses TROPIC01 with two other chips. Its design combines TROPIC01, OPTIGA Trust M and STM32U5 to protect PIN checks, device authenticity and wallet creation.\nHardware wallet audits remain in focus\nThe disclosure gives a rare public view of rival security testing in the hardware wallet market. Ledger Donjon has previously reviewed Trezor devices and published research on physical attack routes.\nAs previously reported by crypto.news, Ledger Donjon earlier said Trezor Safe devices still faced physical attack risks linked to microcontroller use. Trezor said at the time that user funds remained safe when devices came from official sources.\nSeparate crypto.news coverage also warned that some hardware wallets using ESP32 chips faced private key theft risks. That report showed that chip-level flaws remain a key security concern for crypto custody devices.\nOpen security model faces real tests\nTropic Square markets TROPIC01 as an open and auditable secure element. The company says the chip lets researchers inspect and test hardware that would often remain closed under non-disclosure terms.\nThe new flaw shows that open testing can reveal weaknesses before attackers do. It also shows that hardware wallet security depends on full device design, not only one chip.\nFor users, the main guidance remains simple. They should buy devices from official channels, keep firmware updated, protect recovery phrases offline and avoid using any wallet that shows signs of tampering.\n\n\n\n\n\n                Read more:\n            \n\n                Mastercard brings USDC, RLUSD, PYUSD to global settlement network","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)","isDev":false,"isTTM":true,"tenantId":"TBGLOBAL","deviceId":"web-server-community-laohu8-v3","version":"4.43.1","shortVersion":"4.43.1","platform":"web","vendor":"web","appName":"ttm","isIOS":false,"isAndroid":false,"isTiger":false,"isTHS":false,"isWeiXin":false,"isWeiXinMini":false,"isWeiBo":false,"isQQ":false,"isBaiduSwan":false,"isBaiduBox":false,"isDingTalk":false,"isToutiao":false,"isOnePlus":false,"isHuaWei":false,"isXiaomi":false,"isXiaomiWebView":false,"isOppo":false,"isVivo":false,"isSamsung":false,"isMobile":false},"href":"/m/news/2640056149","isCrawlerRequest":true}
