Ledger has introduced the Ledger Agent Stack, an open-source toolkit designed to enable AI agents to manage cryptocurrency wallets without accessing private keys. This innovative solution allows AI agents to read wallet balances, analyze portfolios, and prepare transactions, while ensuring that all sensitive actions require explicit approval on a Ledger hardware device. This launch marks the first product under Ledger's 2026 AI roadmap, emphasizing the importance of human oversight in AI-driven financial tasks. "Agents propose. Humans approve," the company stated, highlighting the continued reliance on human approval for security.
