As blockchains evolve, stablecoins facilitate seamless cross-chain asset migration. When Ethereum experiences high gas fees or a new blockchain offers better yields, users can transfer stablecoins (e.g., wrapping USDT on Polygon) to access different ecosystems. This flexibility allows investors to pursue opportunities across chains while maintaining stable value. In volatile markets, cross-chain stablecoin usage enables quick shifts between networks to avoid congestion or exploit emerging trends.
