Key Highlights
- MoonPay adds hardware signing via Ledger for AI trading agents.
- The update applies to MoonPay’s command-line interface (CLI) wallet, enabling users to authorize operations directly.
- This is the first agent-focused CLI wallet to offer full hardware signing for every transaction.
Crypto payments firm MoonPay has introduced native hardware-wallet support for its automated trading agents, allowing transactions to be verified and signed using devices from Ledger.
According to the official announcement, the update applies to MoonPay’s command-line interface (CLI) wallet, enabling users to authorize operations directly on a secure device while keeping private keys offline.
According to the company, this is the first agent-focused CLI wallet to offer full hardware signing for every transaction.
Automated without custody transfer
Automated trading systems typically require direct access to wallet keys, creating security concerns. MoonPay’s approach separates execution from authorization: the agent prepares transactions, but the user must approve them on the hardware device.
This model allows portfolio management, swaps, and transfers across networks while maintaining self-custody. Supported blockchains include Ethereum, Solana, and several major scaling networks such as Arbitrum, Optimism, Polygon, Base, BNB Chain, and Avalanche.
Multi-chain workflows with manual approval
Once connected via USB, compatible Ledger devices can interact with the CLI environment. The agent can detect wallet balances across supported networks and propose actions such as bridging funds or rebalancing holdings.
Each action still requires a physical confirmation on the device before it is executed. This reflects the growing interest in software that can autonomously manage digital assets. It still requires human intervention for irreversible transactions to mitigate some of the risks that can arise with completely autonomous software, such as errors or accidental actions.
Ivan Soto-Wright, CEO and Founder of MoonPay, commented on the development, stating, “Autonomous agents will manage trillions in digital assets. 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.”
Growing integration
The development comes just weeks after MoonPay announced a collaboration with stablecoin platform M0 to launch PYUSDx, which allows developers to create application-specific stablecoins backed by PayPal USD.
According to MoonPay, the framework aims to simplify the process for developers looking to increase the rollout of stablecoins tailored to individual apps or ecosystems.
Broader context
As AI-driven tools increasingly interact with financial systems, custody and authorization are becoming central design challenges.
By keeping private keys offline and requiring user approval for each action, the approach tests whether automated trading can scale without sacrificing self-custody, a core principle of cryptocurrency ownership.
