Shield is a self-custody crypto wallet offered by Provable Inc., designed to make digital asset transactions private by default. Using zero-knowledge cryptography through Aleo, it aims to protect transaction details, including sender, receiver, token amounts, wallet balance, and transaction history. Users can choose what information to reveal and when, while still viewing their balance in the app and sending funds in seconds.

Shield supports private transactions and offers USDCx and USAD, stablecoins described as dollar-backed and built with Circle and Paxos, with regulatory compliance integrated. The wallet is available for iOS, Android, and Chrome. The site also presents a privacy-focused product ecosystem, including a wallet adapter, a privacy-first explorer, SDK tools, and a playground, alongside documentation and support. Promoted as the official wallet of Aleo, Shield positions privacy as a core feature for managing and moving crypto, while giving users control over the information they share.
