Web3j Six Month Project Update

November 2024 – April 2025

This report summarizes the actions and accomplishments of Web3j, an LF Decentralized Belief mission, from November 2024 to April 2025. Throughout this era, the mission made important strides in bettering the framework’s performance, enhancing consumer engagement, and bolstering total neighborhood interplay. 

Key highlights embrace profitable library upgrades, a noteworthy LF Decentralized Belief mentorship initiative, and demanding integrations that elevate Web3j’s capabilities and compatibility. This doc outlines the achievements towards beforehand set objectives and offers an summary of extra developments that enrich the Web3j ecosystem.

The present mission roadmap is public and might be discovered here.

Objectives Achieved

Over the last six months, the mission has achieved the next objectives:

• Improve web3j-android department to the most recent model and launch libraries as Android artifacts – this was performed through the 2024 mentorship below Hyperledger Basis:
• Organized the First Web3J Hyperledger Ecosystem Summit – an occasion at which we related with the enterprise customers of Web3j and picked up suggestions:
• Join with the neighborhood by means of varied occasions:
• Solved bugs and closed a part of the open points:
  •  Closed 15 open points throughout all Web3j repositories;
  • Applied, reviewed, and merged over 20 Pull requests within the Web3j repositories that fastened completely different bugs or improved the functionalities, corresponding to:
    • Repair ENS CCIP, ERC-3668
    • Repair construct scripts on web3j-android
    • Repair Web3j Transaction logic to return the anticipated chainId when interacting with Solidity 0.8.26 or 0.8.27 
    • Clear subscription after EVM websocket disconnects
    • Catch all of the exception throughout EVM response parsing
    • Enhance codebase by fixing Sonar reported points
• Prolonged ENS integration help (details in this blog post):
  • Added help for Holesky
  • Set Main Title performance
  • Handle ENS document metadata
  • Handle ENS Service metadata
• Refactor the off-chain gasoline supplier contained in the library to work dynamically: https://github.com/LFDT-web3j/web3j/pull/2142
• Enhanced Web3j libraries by migration to Java 21, Kotlin 2.1.0 and integration with a more moderen model of the EVM consumer, Besu:
• Prague/Electra Improve:
  • EIP-7702 help: https://github.com/LFDT-web3j/web3j/pull/2178

Different Accomplishments

Besides the objectives talked about above we managed to realize different accomplishments additionally for Web3j mission:

• Eliminated “Hyperledger” from the mission title to streamline the Web3j model below LF Decentralized Belief
• Submitted and bought approval for 2 Web3j mentorship packages, which can happen in 2025, below Linux Basis Decentralized Belief Membership Program:
  • LFDT – Web3j Libraries Full Development Lifecycle – This mission goals to boost the core Web3j by bettering and bringing updated its part libraries as web3j-unit, web3j-evm, web3j-openapi, specializing in lowering current points and integrating the lacking EIPs. By bettering the extra Web3j libraries, we intention to streamline improvement workflows, improve testability, and create a extra strong framework that simplifies Ethereum improvement for Java and JVM-based tasks.
  • LFDT – Web3j: Enhancing JVM Android Support with Kotlin Wrappers for Solidity Smart Contracts – This mission proposes to construct upon the accomplishments of the prior mentorship by additional enhancing and increasing the functionalities of the Web3j-Android library. Given Kotlin’s prominence as the popular programming language for Android improvement, this initiative goals particularly to facilitate the era of Kotlin-based sensible contract wrappers.
• Added help for Solidity variations 0.8.27, 0.8.28, 0.8.29 in web3j compiler (web3j-sokt) for processing new Solidity Sensible Contracts
• Mounted exterior imports of the Solidity Sensible Contracts  for the ensuing Java Wrappers with the intention to handle advanced sensible contracts that are utilizing completely different libraries throughout the web3j: https://github.com/LFDT-web3j/web3j-solidity-gradle-plugin/pull/78
• Improved the Java Wrapper sensible contract era for recordsdata which have duplicate occasion names: https://github.com/LFDT-web3j/web3j/pull/2124
• Added RPC help for Linea networks: https://github.com/LFDT-web3j/web3j/pull/2150
• Added help for Solidity Customized Error Sort: https://github.com/LFDT-web3j/web3j/pull/2173
• Launched three variations for the library throughout this era:

The previous six months have marked appreciable progress for the Web3j mission. The profitable completion of main updates, together with the numerous improve to web3j-android and improved ENS integration, exemplifies the crew’s dedication to steady enchancment and innovation. 

Moreover, proactive neighborhood engagement, highlighted by the primary Web3j Hyperledger Ecosystem Summit and frequent contributor interactions, has fostered a extra vibrant and collaborative surroundings. Wanting ahead, authorized mentorship packages and ongoing enhancements underscore a promising trajectory for Web3j, making certain it stays a sturdy, versatile software for Ethereum and sensible contract builders.
