MoonPay Launches First AI Crypto Agents Secured by Ledger

Crypto payments platform MoonPay has announced native Ledger hardware wallet support for its AI agents. This marks the first CLI integration on the market where every artificial intelligence operation requires physical confirmation through a USB-connected Ledger device. The feature is already live in MoonPay CLI version 0.12.3.

How the MoonPay and Ledger Integration Works

The new capability allows MoonPay AI agents to execute trading strategies across multiple blockchains, yet every transaction must be physically verified and signed through a Ledger hardware wallet. Compatible devices include Nano X, Stax, and Flex, connected via USB port.

The fundamental difference from existing solutions is that private keys never leave the hardware device's secure chip at any point. The agent constructs the transaction, but without a physical button press on the Ledger, it will not be signed or broadcast to the network. This means that even if the software environment is compromised, funds remain under the owner's full control.

Supported Networks and Automatic Switching

The supported networks include Ethereum, Solana, BNB Chain, and Avalanche at the Layer 1 level, as well as Layer 2 solutions Base, Arbitrum, Polygon, and Optimism. One of the key technical innovations is automatic Ledger app switching during cross-chain workflows. When the AI agent moves from an Ethereum network transaction to a Solana operation, the system independently activates the corresponding app on the device without user intervention.

This greatly simplifies working with multi-chain strategies. Previously, traders had to manually open the correct Ledger app for each blockchain, making automated workflows virtually impossible.

The Security Problem with AI Agents in Crypto

Autonomous AI agents can analyze market data, identify arbitrage opportunities, and execute sophisticated trading strategies. However, the primary barrier to their mainstream adoption remains the risk of private key exposure. If an agent stores keys in a software environment, a hack or vulnerability could result in a complete loss of funds.

MoonPay CEO Ivan Soto-Wright emphasized the scale of the challenge: "Autonomous agents will manage trillions in digital assets. But autonomy without security is reckless." The Ledger integration addresses precisely this issue by separating the agent's computational logic from the transaction signing process.

Industry Response and the Device Management Kit

Ian Rogers, Ledger's Chief Experience Officer (CXO), congratulated MoonPay for being the first company to fully leverage the Device Management Kit — a toolkit for deep integration with hardware wallets. The DMK provides developers with a standardized API for interacting with Ledger devices, paving the way for entirely new categories of applications.

This signals that Ledger is actively expanding the ecosystem of use cases for its devices beyond traditional cryptocurrency storage. The combination of artificial intelligence and hardware security could become a new industry standard, as the growing number of AI agents in DeFi protocols and trading platforms drives increasing demand for robust control mechanisms.

The Human-in-the-Loop Model for AI Agents

MoonPay's architecture implements the human-in-the-loop principle: the agent performs analytical work and prepares transactions, but the final decision always rests with the human operator. This is particularly critical for large volumes — even if the AI model makes an erroneous decision, funds will not be transferred without physical confirmation on the device.

This approach enables users to harness the benefits of automation without risking total loss of control. Traders can configure the agent to monitor dozens of trading pairs and networks simultaneously, reviewing only those transactions that require a signature. The agent can analyze market conditions, construct optimal exchange routes, and prepare batches of operations — while the human simply approves them with a button press on the Ledger.

What This Means for the Crypto Market

The launch of MoonPay Agents with Ledger support marks a significant milestone in the evolution of AI tools for cryptocurrency trading. For the first time, an autonomous agent can operate across eight blockchains simultaneously while maintaining hardware wallet-grade security. This model resolves the fundamental tension between automation and asset protection that had previously held back the development of AI agents in the crypto space.

If the solution proves effective, competitors will likely introduce similar products, shaping a new market segment at the intersection of artificial intelligence and hardware security. For everyday users, this represents an opportunity to delegate routine trading operations to AI while retaining full physical control over their assets.
