The Cancun hard fork of the Ethereum mainnet is planned to be carried out on March 13, 2024. In this upgrade, OP and ARB will undoubtedly play a central role. The Cancun upgrade is a huge benefit for all Ethereum Layer 2 projects, and the currencies involved include OP, ARB, METIS, LRC, IMX, etc. Today OP tries to break through the 4.0 pressure level again to see if it can stand firm this time. If it stands firm, it will lead the layer 2 sector to take off.
