Svmuu News: Cryptocurrency payment service provider MoonPay has announced the introduction of native hardware signature support for its AI agent tool, MoonPay Agents. Under the new architecture, the AI agent can execute trading strategies across multiple mainstream blockchains such as Ethereum and Solana. However, all transactions still require user confirmation via a Ledger device. When the agent identifies cross-chain yield opportunities, it can request the user's signature to bridge USDC from Ethereum to other networks to complete the operation, while the private keys never leave the hardware signing device.
