[MoonPay Introduces Native Hardware Signing Support for AI Tool MoonPay Agents] According to PRNewswire, crypto payment service provider MoonPay has announced the introduction of native hardware signing support for its AI tool, MoonPay Agents. Under the new architecture, AI agents can execute trading strategies on major blockchains such as Ethereum and Solana. However, all transactions still require user confirmation via a Ledger device. When the agent identifies cross-chain arbitrage opportunities, it can request the user to sign off on bridging USDC from Ethereum to other networks to complete the operation, while private keys never leave the hardware signing device.
