MoonPay has launched AI powered crypto agents secured by Ledger hardware signing, allowing users to approve every transaction while keeping private keys protected on device.
Key Takeaways
- MoonPay has introduced Ledger secured AI agents that allow autonomous crypto trading with hardware verified transactions.
- Private keys remain inside the Ledger hardware signer, preventing AI agents from directly accessing wallet keys.
- The integration supports multiple blockchains including Ethereum, Solana, Base, Arbitrum, Polygon, Optimism, BNB Chain, and Avalanche.
- The feature aims to solve one of the biggest security concerns around autonomous AI trading tools.
What Happened?
MoonPay announced native Ledger signer support for MoonPay Agents, allowing users to verify and sign every transaction generated by an AI crypto agent using a physical Ledger device.
The company said the integration makes its command line interface wallet the first agent focused wallet to support Ledger secure signing through the Device Management Kit, addressing growing concerns around security in autonomous crypto trading.

MoonPay Adds Hardware Security to AI Crypto Agents
MoonPay, known for its global crypto payments infrastructure, is expanding into the emerging field of AI-powered crypto agents. These tools are designed to automatically execute trading strategies, rebalance portfolios, and move assets across blockchain networks with minimal human input.
However, one of the biggest concerns surrounding these systems has been wallet security. Many AI based trading tools require users to grant direct access to their wallet keys, which introduces significant risk if the system fails or behaves unpredictably.
MoonPay said its new integration removes that risk by ensuring private keys never leave the Ledger hardware signer. Instead of granting full wallet control to the AI agent, users must approve every transaction directly on their Ledger device.
This means the agent can analyze opportunities and prepare transactions, but the final approval remains with the user. Ivan Soto Wright, CEO and Founder of MoonPay said:
How the AI Agents Work With Ledger Devices?
MoonPay explained that users can connect their Ledger device directly to the MoonPay command line interface wallet using USB. Once connected, the system can automatically detect wallets across supported blockchain networks.
The integration currently supports multiple major networks including:
The system also includes automatic Ledger app switching, allowing the AI agent to interact with multiple blockchains within a single workflow without requiring manual switching between applications on the device.
According to MoonPay, the AI agent can perform actions such as swaps, bridging assets, and transfers while routing every transaction through the Ledger signer for on device approval.
For example, a user might ask the agent to rebalance a multi-chain portfolio. The AI could detect a yield opportunity on Base, request to bridge USDC from Ethereum, and then prompt the user to approve the transaction using their Ledger device.
Because each transaction requires hardware approval, the company says there is no risk that an AI agent could misuse funds or act on hallucinated instructions.
Industry Shift Toward Agent Focused Wallets
The launch also highlights a growing trend toward developer focused wallets and AI driven financial tools.
Ian Rogers, Chief Experience Officer at Ledger, said the rise of AI agents is creating demand for stronger wallet security.
Rogers said:
MoonPay believes the new system could play an important role as AI-powered financial automation continues to expand across the crypto industry.
CoinLaw’s Takeaway
In my experience covering crypto security, wallet key management remains one of the biggest risks in the industry. Giving automated software direct control over private keys has always felt uncomfortable.
What MoonPay is doing here makes practical sense. The AI agent can handle the complex trading logic, while the user still controls the final approval through a hardware device. I found this model much closer to how crypto security should evolve as automation grows.
If AI agents are truly going to manage trillions in digital assets in the future, then hardware level security like Ledger signing will likely become the standard rather than the exception.
