Ledger and MoonPay are teaming up to give humans back the final say over AI-controlled crypto transactions.
MoonPay announced Friday that its Agents platform — software that lets autonomous AI agents hold and move crypto — now supports Ledger hardware wallets. That means trades, swaps and transfers initiated by an AI agent are routed through a secure Ledger signer and require manual approval on the physical device before they execute.
“This is just the beginning,” MoonPay CEO Ivan Soto-Wright told Decrypt, saying MoonPay plans to add support for other hardware wallets and to position MoonPay as the “financial rail” for developers building agent-driven features across trading, gaming, commerce and treasury use cases. MoonPay Agents currently work with Ledger Nano S Plus, Nano X, Nano Gen5, Stax and Flex devices.
MoonPay says its agents can detect and interact with wallets across multiple chains — including Ethereum, Solana, Optimism, Avalanche and Base — and that automatic Ledger app switching enables agents to move across those networks while routing swaps, bridges and transfers through the on-device signer for approval.
Ledger’s Chief Experience Officer Ian Rogers framed the integration as a wider trend: “There is a new wave of CLI and agent-centric wallets emerging, and these will need Ledger security as a feature, too,” he said.
The move arrives as AI agents gain traction in crypto trading and asset management. Projects and teams such as Eliza Labs, Fetch AI and Coinbase have been building systems that can autonomously send, receive and manage digital assets. MoonPay first launched its Agents product in February to give AI systems direct access to wallets and transaction capabilities.
But handing keys or transaction authority to AI remains risky. Agents have been targets for attacks (including prompt-injection-style exploits), and many implementations still rely on private keys stored on disk. “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, told Decrypt previously.
By forcing human confirmation on a hardware device, the Ledger-MoonPay tie-up addresses a key security gap in agent-driven finance — lowering some risk without eliminating it — and signals that security-first UX will be central as autonomous agents move deeper into crypto markets.
