Yes, Ethereum can achieve unified asset management across different blockchains through cross-chain bridges. These bridges enable seamless asset transfers by locking tokens on one chain (e.g., Ethereum) and minting equivalent tokens on another (e.g., Binance Smart Chain). Protocols like Wormhole, Multichain, and LayerZero facilitate interoperability, allowing users to manage assets across ecosystems efficiently. For example, Wrapped Bitcoin (WBTC) on Ethereum represents Bitcoin via a bridge. However, risks like smart contract vulnerabilities or centralization in some bridges require careful consideration. By leveraging bridges, users can unify assets, enhance liquidity, and access diverse DeFi opportunities across blockchains.
