USDCx on Aleo is now live in the Ledger Wallet™ app 🎉 @Ledger and Aleo come together to bring private stablecoins to a mainstream hardware wallet for the first time. USDCx on Aleo is a dollar-denominated stablecoin built on Aleo. For years, holding meaningful value onchain has meant a tradeoff between security and privacy. Blockchain analytics, exchange records, and behavioral patterns make it increasingly straightforward to connect an address to the person behind it 🔎 Once that link is made, every balance and transaction attached to it is permanent. Moving to a centralized exchange solved public visibility by trading away ownership. Self-custody removes that custodial risk, but if your address is public, your balance and transaction history stay visible to anyone who finds it. Until today, it hasn't been possible to achieve both hardware cold storage and privacy. Now, every transaction is confirmed and signed on your Ledger device's secure screen, while amounts, sender, and receiver stay private. Your keys stay offline, and your balance stops being public information. Learn more 👇 aleo.org/post/private-usdcx-…

🌕 Under the same full moon, wherever you are. Happy Mid-Autumn Festival from #HashKey. 💙
