Sportsbet.io is a cryptocurrency gambling and sports betting platform operated by mBet Solutions N.V. under the Yolo Group umbrella, licensed in Curaçao. On June 22, 2024, blockchain investigator ZachXBT publicly identified that the platform's hot wallets were drained of approximately $3.5 million in USDT and TRX, attributing the attack to the same threat actor who hours later stole an estimated $55 million from Turkish exchange BtcTurk, with stolen funds allegedly commingled between both hacks. The platform has drawn ongoing scrutiny for operating in regulatory grey markets, serving users in jurisdictions where it holds no local license, and for systemic user complaints involving account closures and fund seizures following wins. Yolo Group founder Tim Heath confirmed in 2025 that the brand is being wound down in favor of fully regulated markets.

C&M Software (also styled CMSW) is a Brazilian financial technology company authorized by the Banco Central do Brasil to provide connectivity between smaller financial institutions and Brazil's national payment infrastructure, including the PIX instant-payment system. On June 30, 2025, hackers exploited credentials sold by an insider employee to drain approximately R$800 million (roughly USD 140–148 million) from reserve accounts of at least six financial institutions, in what became Brazil's largest recorded banking cyberattack. A portion of the stolen funds—estimated at USD 30–40 million—was subsequently laundered through Latin American OTC desks and crypto exchanges using Bitcoin, Ethereum, and Tether USDT, with on-chain investigator ZachXBT playing a central role in tracing and partially freezing the laundered assets.

Strike (operated by Zap Solutions, Inc.) is a Bitcoin and Lightning Network payments application founded by Jack Mallers. The platform has faced scrutiny over a 2023 data breach it initially denied, the use of Tether (USDT) as a backing for purported USD cash balances for non-US users, and a 2026 proposed merger with Twenty One Capital (XXI) that raises serious conflict-of-interest concerns given Mallers serves as CEO of both entities.
