Web3j Six Month Project Update

November 2024 – April 2025

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

Key highlights embody 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 further developments that enrich the Web3j ecosystem.

The present undertaking roadmap is public and might be discovered right here.

Targets Achieved

Over the past six months, the undertaking has achieved the next objectives:

Improve web3j-android department to the newest model and launch libraries as Android artifacts – this was carried out 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 numerous 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 totally different bugs or improved the functionalities, akin to:Repair ENS CCIP, ERC-3668Fix construct scripts on web3j-androidFix Web3j Transaction logic to return the anticipated chainId when interacting with Solidity 0.8.26 or 0.8.27 Clear subscription after EVM websocket disconnectsCatch all of the exception throughout EVM response parsingImprove codebase by fixing Sonar reported issuesExtended ENS integration help (particulars on this weblog submit):Added help for HoleskySet Main Title functionalityManage ENS document metadataManage ENS Service metadataRefactor the off-chain fuel supplier contained in the library to work dynamically: https://github.com/LFDT-web3j/web3j/pull/2142Enhanced Web3j libraries by migration to Java 21, Kotlin 2.1.0 and integration with a newer 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 undertaking:

Eliminated “Hyperledger” from the undertaking identify to streamline the Web3j model below LF Decentralized TrustSubmitted and obtained approval for 2 Web3j mentorship packages, which can happen in 2025, below Linux Basis Decentralized Belief Membership Program:LFDT – Web3j Libraries Full Improvement Lifecycle – This undertaking goals to reinforce the core Web3j by enhancing and bringing updated its element libraries as web3j-unit, web3j-evm, web3j-openapi, specializing in decreasing present points and integrating the lacking EIPs. By enhancing 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 Help with Kotlin Wrappers for Solidity Sensible Contracts – This undertaking 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 technology of Kotlin-based good 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 ContractsFixed exterior imports of the Solidity Sensible Contracts  for the ensuing Java Wrappers so as to handle advanced good contracts that are utilizing totally different libraries inside the web3j: https://github.com/LFDT-web3j/web3j-solidity-gradle-plugin/pull/78Improved the Java Wrapper good contract technology for recordsdata which have duplicate occasion names: https://github.com/LFDT-web3j/web3j/pull/2124Added RPC help for Linea networks: https://github.com/LFDT-web3j/web3j/pull/2150Added help for Solidity Customized Error Kind: https://github.com/LFDT-web3j/web3j/pull/2173Released three variations for the library throughout this era:

The previous six months have marked appreciable progress for the Web3j undertaking. The profitable completion of main updates, together with the numerous improve to web3j-android and improved ENS integration, exemplifies the workforce’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, guaranteeing it stays a strong, versatile device for Ethereum and good contract builders.
