Fact Check

The claim is directly confirmed by an official press release from MoonPay (via PRNewswire) and a detailed report from CoinDesk.

Summary

MoonPay officially announced expanded native hardware signing support for MoonPay Agents across Ethereum, Solana, and other blockchains, according to PRNewswire. The company’s AI agent wallet requires users to confirm every transaction on a Ledger hardware device, keeping private keys off the agent while allowing blockchain activity such as USDC bridging from Ethereum for cross-chain opportunities. The update adds concrete multi-chain support details to MoonPay’s earlier launch of Ledger-secured signing for its command-line interface wallet, which the company said was built to address security concerns around autonomous crypto agents that can trade, rebalance portfolios, and move assets across networks.
