Crypto payments company MoonPay has added Ledger hardware wallet signing to its command line interface (CLI) wallet for MoonPay agents, a move the company says addresses a security challenge introduced by standalone crypto 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-focused wallet to support Ledger’s secure signing through the company’s Device Management Kit.
Autonomous crypto agents are a growing category of tools designed to execute trading strategies, rebalance portfolios, and move assets between chains without constant human intervention. But security concerns have slowed adoption, as many implementations require users to give direct access to wallet keys.
“Autonomous agents will manage billions of digital assets,” said Ivan Soto-Wright, CEO and founder of MoonPay. “But autonomy without security is unwise. We built MoonPay agents with Ledger so intelligence can scale without giving up control. The agent executes. The human stays in the loop.”
Ian Rogers, head of experience at Ledger, said the integration reflects the growing number of developer-focused wallets and AI-based tools entering crypto.
“A new wave of CLI and agent-centric wallets is emerging, and these will also need Ledger security as a feature,” Rogers said.
