Crypto payments firm MoonPay 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 autonomous 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 across chains without constant human input. But security concerns have delayed 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 built MoonPay Agents with Ledger so intelligence can scale without relinquishing control. The agent executes. The human stays in the loop.”
Ledger’s head of experience, Ian Rogers, said the integration reflects the growing number of developer-focused wallets and AI-powered tools moving into crypto.
“There is a new wave of CLI and agent-centric wallets coming, and these will also need Ledger security as a feature,” Rogers said.
