In 2025, a type of security incident has caused particular frustration—it doesn't occur on just one chain but involves a synchronized attack script sweeping across multiple chains such as BNB Chain, Base, Taiko, and others. Before you can even react to what’s happening, assets have already been transferred away. This cross-chain synchronized attack immediately turns the "multi-chain deployment" from a strategic advantage into a risk amplifier: the more chains involved, the more vulnerabilities there are, and the higher the likelihood of being attacked.

What are the direct consequences? Funds begin to avoid complex cross-chain routes. Especially concerning "USD assets"—it's unlikely you'll want to lock core active funds into cross-chain bridges, cross-chain messaging protocols, or cross-chain contracts. At this point, a new need emerges: is there a way to make USD assets directly available on each chain without repeatedly "moving" them?

This is why stablecoin design becomes critical. USDD, as a decentralized, over-collateralized stablecoin pegged 1:1 to the USD, can directly serve as collateral, a lending tool, liquidity provider, or liquidation asset within DeFi. When multi-chain risk events occur frequently, the smartest approach is to keep the cash layer simple—allocate some funds into USDD and lock them on-chain, and only redistribute to various strategy layers when actual operations are needed, rather than leaving idle funds to cross-chain around with you.

Deeper logic reveals that USDD’s pegging mechanism includes built-in correction paths, over-collateralization provides a buffer for redemption, and multi-chain deployment ensures consistency. The combination of these three layers of protection forms a comprehensive approach to addressing "cross-chain risks."
