MoonPay launches AI trading agent supporting Ledger signatures

According to PR Newswire, cryptocurrency payment service provider MoonPay announced the introduction of native hardware signature support for its AI agent tool, MoonPay Agents.

Under the new architecture, the AI agents can execute trading strategies on multiple mainstream blockchains such as Ethereum and Solana, but all transactions still require user confirmation through a Ledger device. When the agent discovers cross-chain profit opportunities, it can request the user to sign to bridge USDC from Ethereum to other networks to complete the operation, while the private key never leaves the hardware signing device.
