WHY THIS MATTERS
As AI-driven trading tools and autonomous agents gain traction in the crypto ecosystem, security has become a major barrier to adoption. Traditionally, giving an AI agent the ability to trade on behalf of a user required granting access to private keys—something many investors are unwilling to do. MoonPay’s integration with Ledger hardware signers addresses this concern by ensuring that private keys remain securely stored on hardware devices, while every transaction still requires explicit user approval. This model allows AI agents to assist with tasks such as portfolio rebalancing or cross-chain transfers without compromising control over digital assets.
MoonPay, the leader in global crypto payments, has announced native Ledger signer support for MoonPay Agents, making it the first CLI wallet with an integration enabling users to verify and sign every transaction on a Ledger secure signer. Private keys never leave the hardware.
The launch addresses the biggest barrier to autonomous AI trading: security. Until now, giving an AI agent access to your crypto meant giving up control of your keys. MoonPay Agents with Ledger support eliminates that tradeoff, giving agents full trading capabilities across Ethereum, Solana, and all major chains while the user signs every transaction using their Ledger signer.
“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.”
What This Looks Like
A user can ask their agent to rebalance a multi-chain portfolio. The agent spots a yield opportunity on Base, wants to bridge USDC from Ethereum and asks the user to sign the transaction. The keys never leave the signer, and the user is responsible for approving all immutable transactions – there is no risk the agent will hallucinate and misuse the funds.
How It Works
Connect any Ledger signer (Ledger Nano S Plus™, Ledger Nano X™, Ledger Nano™ Gen5, Ledger Stax™, or Ledger Flex™) via USB to MoonPay CLI. The agent automatically detects wallets across all supported networks, including Base, Solana, Arbitrum, Polygon, Optimism, BNB Chain, and Avalanche.
Automatic Ledger app switching lets an agent move across multiple chains in a single workflow with no manual steps. Swaps, bridges, and transfers all routes through the Ledger signer for on-device approval.
“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,” said Ian Rogers, Chief Experience Officer at Ledger.

FF NEWS TAKE
AI-powered trading agents are emerging as a new frontier in digital asset management, but security concerns remain a major hurdle.
MoonPay’s integration with Ledger highlights how the industry is attempting to combine automation with strict self-custody safeguards. As AI begins to play a larger role in managing crypto portfolios, solutions that allow users to maintain full control of their private keys while leveraging intelligent trading tools will likely become increasingly important.
