Ledger has unveiled the Agent Stack toolset, enabling AI agents to interact with cryptocurrency wallets. These agents can check balances, analyze portfolios, and prepare transactions, but any signed operations require device confirmation.

According to the company, Agent Stack underwent closed testing with over 1,000 agents. It is described as an open toolset for the “agents propose, humans confirm, Ledger device executes” scenario.
Agent Stack includes Device Management Kit Skills, Ledger Wallet CLI, Ledger Enterprise CLI, and Ledger Enterprise Multisig CLI. The documentation states that Ledger Wallet CLI allows agents or users to access account data, check balances and transaction history, prepare asset transfers, and more. Actions not requiring signatures can be performed without the device, but any asset movement must be confirmed on the Ledger screen.
A separate section notes that Wallet CLI supports Bitcoin, Ethereum, EVM-compatible networks, and Solana.
Ledger also suggests using devices beyond cryptocurrency wallets. Through OpenPGP, they can store keys for accessing encrypted files, environment variables, and API tokens. Through FIDO2, they can serve as hardware login keys for GitHub, npm, 1Password, Discord, and other services.
The company linked the release to its AI security roadmap for 2026. In the second quarter, Ledger plans to launch identification and command-line tools, in the third quarter, Agent Intents and Agent Policies layers for action confirmation and rules, and in the fourth quarter, the Proof of Human mechanism.
Earlier, Ledger Donjon researcher Baptiste Boileau disclosed a vulnerability in Tangem hardware wallets. A laser fault injection attack allows resetting the card password and gaining control over the stored assets.
In May, a CoinDesk source reported that Ledger’s IPO was postponed indefinitely due to challenging market conditions.
