What to know : MoonPay integrated Ledger wallet signing into its MoonPay Agents, allowing users to approve every AI-initiated crypto transaction on a hardware device while keeping private keys away from the agent. The feature aims to address security concerns around autonomous crypto trading, enabling AI agents to execute strategies across multiple blockchains while requiring human approval through a Ledger signer.
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 every transaction generated by an AI agent using a Ledger hardware device, ensuring 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 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 built MoonPay Agents with Ledger so intelligence can scale without surrendering control. The agent executes. The human stays in the loop.”
Ledger’s chief experience officer, Ian Rogers, said the integration reflects the growing number of developer-focused wallets and AI-driven tools entering crypto.
“There is a new wave of CLI and agent-centric wallets emerging, and these will need Ledger security as a feature, too,” Rogers said.
