You Can Control an AI Agent’s Crypto Spending With Ledger Hardware Wallets and MoonPay

Ledger has added hardware wallet support for MoonPay Agents, allowing human users to verify and sign transactions initiated by their deployed AI agents, MoonPay announced on Friday.

The announcement comes as the crypto industry has embraced artificial intelligence in the form of autonomous AI agents. The Ledger integration routes agent-generated trades, swaps, and transfers through a secure signer that requires manual approval on the hardware wallet.

“The Ledger integration is just the beginning. We plan to support additional hardware wallets and look forward to collaborating with more partners across the ecosystem,” MoonPay CEO Ivan Soto-Wright told Decrypt. “Any developer building an agent that needs to move value can plug MoonPay in as the financial rail across trading, gaming, commerce, treasury, and beyond.”

MoonPay Agents support Ledger Nano S Plus, Nano X, Nano Gen5, Stax, and Flex devices. According to MoonPay, agents can detect and interact with wallets on blockchains including Ethereum, Solana, Optimism, Avalanche, and Base.

Automatic Ledger app switching lets an agent move across blockchain networks, MoonPay explained. Swaps, bridges, and transfers all routes through the Ledger signer for on-device approval.

“There is a new wave of CLI and agent-centric wallets emerging, and these will need Ledger security as a feature, too,” Ledger Chief Experience Officer Ian Rogers said in a statement.

AI agents are gaining traction in crypto trading, as developers including Eliza Labs, Fetch AI, and Coinbase build systems that can send, receive, and manage digital assets autonomously. MoonPay launched its Agents software in February to give AI systems access to crypto wallets and the ability to execute transactions.

However, giving your cryptocurrency to an AI comes with risk, and security has been an ongoing concern as agents remain susceptible to cyber attacks like prompt injection attacks.

“Today, most agents with wallets just have a private key sitting on disk somewhere, and you’re already seeing those wallets get exploited, or people lose access when agents make mistakes,” Erik Reppel, head of engineering for Coinbase Developer Platform, previously told Decrypt.
