MoonPay has unveiled its AI trading tool, MoonPay Agents, now featuring native hardware signing support. This enhancement allows AI agents to execute trading strategies on major blockchains like Ethereum and Solana, while ensuring all transactions are confirmed by users through Ledger devices. The system maintains security by keeping private keys within the hardware device. When cross-chain yield opportunities are detected, the AI agent can prompt users to authorize the bridging of USDC from Ethereum to other networks.
