Ledger has introduced AI agents without access to private keys.

Ledger Agent Stack – an open-source tool that enables AI to analyze wallet balances, evaluate portfolios, prepare transactions, and suggest payments. However, any action involving assets can only be carried out after confirmation by the owner on a Ledger hardware device.

Even if the agent is compromised, an attacker won't be able to transfer funds or gain access to protected data without physical confirmation on the Ledger device.
