According to the latest data, in the past month, approximately 19 million USDC digital tokens completed the bridging process from the Optimism blockchain to Ethereum via a tool called Jumper. This large-scale liquidity transfer not only reflects the widespread application of USDC as a stablecoin in the global cryptocurrency market but also reveals the importance and convenience of fund flow between different blockchains. The bridging from Optimism to Ethereum not only helps improve the flexibility of funds but may also bring lower transaction fees and faster confirmation times for users, further promoting the process of cross-chain interoperability of crypto assets.
