🏆 World Cup season has everyone making predictions. Scores. Odds. Champions. But on prediction markets, the biggest risk may not be guessing wrong. It may be what your wallet is actually signing ⚠️ Polymarket’s frontend was compromised, leading to asset losses for users.

Not an ambassador or any relations, but get a @KeystoneWallet for your ADA - the user experience is much better than Ledger and also I don't get a message about battery charging problems every time I use it. If you don't have that kinda money, get a Ledger Nano S.

⚠️ The recent SecondFi/Yoroi exploit didn't begin when users clicked "Send." It began the moment some wallets were created. Weak entropy can produce predictable private keys. Once that happens, every address and every future transaction inherits the same risk. Software wallets

No better time to buy a @KeystoneWallet than the present. Will make you completely immune to most wallet vulnerabilities. Also their unwavering support for Cardano deserves massive respect IMHO.

1/ Most Cardano holders face a choice: convenient software wallets OR secure hardware wallets with poor ADA support. Because hardware wallets treated Cardano as an afterthought. We took it as a priority. Here's how we became the go-to hardware wallet for ADA holders 👇

⚠️ If you spot any GTA 6 early access for crypto payments, treat it as a red flag 🚩 Here's why: GTA 6 is in the pre-order stage. There is no early access, and Rockstar isn't selling any. What you're looking at is a payment page dressed up as a launch page: neon Vice City art,

Cybercriminals are launching fake GTA 6 pre-order sites offering early access for crypto payments. Scammers are using the hype around one of the biggest game launches ever to lure players into handing over personal information, downloading malicious files, and losing money.
