Shield, a privacy-first wallet built on the Aleo blockchain, is now available on iOS, enabling users to conduct private transfers and cross-chain exchanges directly from their iPhones. The wallet supports private stablecoins like USDCx and USAD, encrypting transaction records by default and utilizing zero-knowledge proofs to maintain privacy without revealing transaction details. Aleo, the blockchain underpinning Shield, is designed to enhance digital payment privacy through zero-knowledge cryptography, combining encryption with smart contract programmability. The Aleo Foundation, supported by investors such as a16z, SoftBank, and Coinbase Ventures, aims to develop secure on-chain financial infrastructure.
