MoonPay Introduces Hardware Signature Support for AI Tool

MoonPay, a provider of cryptocurrency payment services, has announced the integration of native hardware signature support for its AI agent tool, MoonPay Agents. According to ChainCatcher, this new architecture allows AI agents to execute trading strategies across major blockchains like Ethereum and Solana. However, all transactions require user confirmation via a Ledger device. When the agent identifies cross-chain profit opportunities, it can request user signatures to bridge USDC from Ethereum to other networks, ensuring that private keys remain secure within the hardware signature device.
