NEW YORK — March 13, 2026
Executive Summary
MoonPay has announced the launch of native Ledger signer support for MoonPay Agents, introducing what the company describes as the first command-line interface (CLI) wallet that integrates Ledger secure signing directly into AI-driven crypto agents. The capability enables users to deploy autonomous agents that can execute crypto trading operations while requiring each transaction to be verified and approved on a physical Ledger hardware signer, ensuring private keys remain secured within the device.
According to MoonPay, the integration addresses a key security challenge associated with autonomous AI agents operating in cryptocurrency markets. Historically, allowing an AI system to execute transactions required users to provide access to their wallet keys. With MoonPay Agents and Ledger signer support, the agent can perform operations across multiple blockchain networks while the user retains control of transaction approval through their hardware signer.
The system supports operations across major blockchain networks including Ethereum, Solana, Base, Arbitrum, Polygon, Optimism, BNB Chain, and Avalanche. The feature is now available in MoonPay CLI version 0.12.3, allowing users to connect compatible Ledger devices and begin using AI agents that execute transactions while the final signing step occurs on the hardware device.
Announcement Overview
MoonPay announced the introduction of native Ledger signer integration for MoonPay Agents, expanding the security capabilities of its AI-driven crypto trading tools. The company stated that the integration enables users to deploy autonomous agents capable of performing blockchain transactions while requiring every action to be verified through a Ledger hardware signer.
MoonPay Agents operate through a command-line interface wallet environment, allowing users to instruct an AI agent to perform tasks such as portfolio management, asset transfers, or multi-chain trading strategies. With the Ledger integration, every transaction initiated by the agent must be signed by the user using a Ledger secure device, ensuring that private keys remain isolated within the hardware signer.
According to MoonPay, the system allows AI agents to perform trading and asset management tasks across multiple blockchain ecosystems while preserving hardware-based security controls. This model enables agents to perform operations while the user remains responsible for approving all transactions before they are executed on-chain.
The launch reflects MoonPay’s focus on combining AI-driven financial automation with hardware-based digital asset security, enabling users to interact with autonomous agents without transferring custody of private keys or exposing sensitive cryptographic credentials.

Security Challenge Addressed by the Integration
MoonPay stated that the introduction of Ledger signer support addresses a security limitation that has historically affected autonomous AI trading systems in cryptocurrency markets.
According to the company, allowing AI agents to trade digital assets typically required granting those systems direct access to private keys or wallet credentials. This requirement created a tradeoff between automation and security, as users had to relinquish control of their cryptographic keys in order to enable autonomous transaction execution.
MoonPay Agents with Ledger support introduce a model in which private keys remain stored exclusively within the hardware device, while the agent executes trading logic and transaction preparation. Each transaction must then be signed on the Ledger device before it can be broadcast to the blockchain.
This design allows autonomous agents to interact with decentralized networks while ensuring that cryptographic signing remains under direct user control through the hardware signer.
MoonPay stated that this model enables users to deploy automated trading agents while maintaining self-custody of their digital assets.
What This Looks Like
MoonPay described an example workflow illustrating how the integrated system operates in practice.
A user may instruct their AI agent to rebalance a multi-chain cryptocurrency portfolio. During this process, the agent analyzes opportunities across supported blockchain networks and identifies a potential yield opportunity on Base.
To execute the strategy, the agent determines that USDC must be bridged from Ethereum to Base. The agent then prepares the transaction and requests the user’s approval.
The transaction is presented to the user for signing through their Ledger hardware signer, which verifies and confirms the operation on the device. The private keys remain secured within the hardware signer throughout the process.
MoonPay stated that this model ensures that the user remains responsible for approving each immutable blockchain transaction while the AI agent handles execution logic and workflow automation.
How It Works
MoonPay Agents with Ledger support operate through the MoonPay CLI environment, which enables users to connect compatible Ledger devices through a USB connection.
Once connected, the system automatically detects the user’s wallets across supported blockchain networks. These networks include:
- Base
- Solana
- Arbitrum
- Polygon
- Optimism
- BNB Chain
- Avalanche
MoonPay stated that the system includes automatic Ledger application switching, enabling agents to interact with multiple blockchain networks within a single workflow without requiring manual switching between device applications.
Through this mechanism, AI agents can perform actions such as:
- Token swaps
- Asset bridges between chains
- Wallet transfers
Each operation is routed through the Ledger device for on-device transaction approval before execution on the blockchain.
Leadership Statements
Ivan Soto-Wright, Chief Executive Officer and Founder of MoonPay, said the company developed the integration to support secure AI-driven financial automation.
“Autonomous agents will manage trillions in digital assets,” said Ivan Soto-Wright. “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 executives also commented on the integration and the evolving role of hardware security in emerging wallet technologies.
Ian Rogers, Chief Experience Officer at Ledger, said the partnership reflects a new generation of developer-focused wallets and agent-based systems.
“For years, Ledger integration has been a checkbox feature for wallets. There is a new wave of CLI and agent-centric wallets emerging, and these will need Ledger security as a feature, too. Congrats to MoonPay for being the first to leverage Ledger’s Device Management Kit and integrate Ledger into MoonPay Agents.”
