Web3j has been significantly used by Enterprises for JVM web3 development, and it is the only actively developed library supporting permissioning and private txs for Besu (L1 client). Since many Enterprises are already using Web3j, they can leverage Web3j to deploy secure, scalable, and efficient blockchain solutions on L2 chain like Arbitrum, reducing both development time and cost. This adaptation enables seamless transition and operation across different blockchain layers, enhancing operational efficiency and offering robust solutions to complex blockchain challenges.
