A social media post discusses Tangem's cryptocurrency hardware wallet ecosystem, explaining self-custody concepts and how Tangem's products—wallet cards, rings, apps, and payment solutions—integrate security with practical everyday usage for crypto users.
X announced Bitcoin can be purchased directly in its app, a major social media platform adoption. Meanwhile, white-hat researchers recovered 52.37 Bitcoin from a COLDCARD hardware wallet exploit and returned funds to victims rather than demanding a bounty.
Two X posts discuss wallet security and a cryptocurrency theft. The first explains hardware-based wallet security using isolated cryptographic signing to prevent unauthorized transactions from phishing and malicious apps. The second reports a 26,414 USDT loss from WealthManagementV2 contract due to suspected leaked private key compromising owner privileges, allowing the attacker to manipulate contract parameters and mint inflated interest.
