Jesse Pollak, co-founder of Base, revealed that the Base research team has launched a proof of concept (POC) for cross L2 calling standard RIP-7755. This standard aims to achieve seamless cross chain interoperability between different Ethereum Layer2 networks, particularly mainstream layer 2 networks such as Optimism and Arbitrarum. Jack Chuma, a member of the Base research team, stated that the concept validation of RIP-7755 is applicable to blockchains that comply with the EIP-4788 standard and can currently verify the status of the OPStack chain and Arbitrarum. @changde
