Ledger launches Agent Stack: AI agents gain access to hardware wallets, but the final say remains with the human
Ledger, a recognized leader in hardware cryptocurrency wallets, has officially introduced the Agent Stack toolkit. This solution enables AI agents to interact with Ledger crypto wallets, but with one critically important condition: any transactions require mandatory confirmation on the device itself.
According to my data, Agent Stack has already undergone closed beta testing with over 1,000 agents. The solution's architecture is built on the principle of "agents propose, humans confirm, Ledger executes." The toolkit includes several key components: Device Management Kit Skills, Ledger Wallet CLI, as well as Enterprise and Enterprise Multisig versions.
According to the documentation, Ledger Wallet CLI allows an agent or user to retrieve account data, check balances and transaction history, and prepare asset transfers. Actions that do not require signing are performed without the device. However, any operation involving the movement of funds must be confirmed on the hardware wallet's screen. Wallet CLI supports Bitcoin, Ethereum and all EVM-compatible networks, as well as Solana.
Ledger is also expanding the use cases of its devices beyond crypto wallets. Through OpenPGP, they can store keys for accessing encrypted files and API tokens, and through FIDO2, they can be used as a hardware login key for GitHub, npm, 1Password, and Discord.
AI Security Roadmap for 2026
The company linked the Agent Stack release to the publication of its AI security roadmap for 2026. In the second quarter, the launch of identification and command-line tools is planned. In the third quarter, Agent Intents and Agent Policies layers for confirmation and action rules will appear. And in the fourth quarter, Ledger intends to implement a Proof of Human mechanism.
Earlier, researchers from the Ledger Donjon division disclosed a physical vulnerability in Tangem hardware wallets. An attack via laser fault injection can reset the card's password and gain control over assets. This incident once again underscores the importance of multi-factor protection.
Let me remind you that in May, it became known that Ledger's IPO was postponed indefinitely due to complex market conditions. However, the launch of Agent Stack demonstrates that the company continues to actively develop its ecosystem.
My expert assessment: Agent Stack is a logical and timely step. Integrating AI agents with hardware wallets through the "hardware as final confirmation" model solves a key security problem: an agent can prepare a transaction but can never sign it without the user's knowledge. This is precisely the balance between automation and control needed for the mass adoption of DeFi and Web3.
