This addition enables the capability to send blob transactions, benefiting both L1 and L2 users by substantially reducing storage costs on the L1 layer. Building on this momentum, we aim to enhance Web3j's capabilities to interact seamlessly with L2 client nodes, such as Arbitrum, Optimism, and Polygon-zkEVM, starting with Arbitrum and gradually extending support to other networks.\n", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "web3labs", "projectTwitter": "web3labs"}
