PANews reported on May 14th that Aleo has officially completed its integration with Ledger Wallet, bringing fully privacy-preserving zero-knowledge proof (ZK) transactions to hardware wallet self-custody scenarios. On the Aleo network, when users initiate transactions through Ledger, information such as the sender, receiver, and transaction amount remains confidential, while the private key is always stored in the Ledger device and never leaves the hardware signature unit.

Aleo stated that supporting privacy transactions in hardware wallets has long been a technical challenge in the privacy blockchain field. Traditional hardware wallets are primarily designed for transparent blockchains, with relatively straightforward transaction signing processes; however, privacy transactions require generating zero-knowledge proofs around private state, making the signing process more complex. The official statement indicates that this feature's implementation is thanks to dedicated technical collaboration between Aleo and the Ledger engineering team, and it is currently available on Ledger Wallet, covering over 8 million Ledger devices.
