Crypto payments company MoonPay has added hardware wallet signing Ledger to its command line interface (CLI) wallet for MoonPay agents, a move the company says addresses a security challenge introduced by autonomous cryptocurrency trading tools.
The new feature allows users to verify and sign each transaction generated by an AI agent using a Ledger hardware device, ensuring that private keys never leave the hardware signer. MoonPay said the integration makes the CLI wallet the first agent-centric wallet to support secure Ledger signing through the company’s device management kit.
Autonomous crypto brokers are a growing category of tools designed to execute trading strategies, rebalance portfolios, and move assets across chains without constant human intervention. But security issues have slowed adoption, because many implementations require users to hand over direct access to wallet keys.
“Autonomous agents will manage trillions in digital assets,” said Ivan Soto-Wright, CEO and founder of MoonPay. “But autonomy without security is reckless. We created MoonPay agents with Ledger so that intelligence can scale without giving up control. The agent executes. The human stays informed.”
Ledger chief experience officer Ian Rogers said the integration reflects the growing number of developer-focused wallets and AI-powered tools entering cryptocurrencies.
“There is a new wave of CLI and agent-centric wallets emerging, and these will also need Ledger security as a feature,” Rogers said.
