Neo community developer isleepcode released two open-source Neo N3 tools in May: neovest on May 12 and Gasetta on May 16. Gasetta generates AI summaries of Neo GitHub activity and tracks commentary from co-founders Da Hongfei and Erik Zhang to help gauge Neo N4 progress. neovest is an alpha, trustless token-vesting smart contract with multiple schedule types and no external audit yet.

AgentCypher has launched Joker King, an autonomous AI-agent card battle game on Neo X with a US $25,000 seasonal prize pool paid out across multiple cycles. The first cycle runs from March 26 to April 3 and includes a US $5,000 pool, while matches are settled on-chain via smart contracts without human involvement during gameplay.

On March 17, AxLabs released two TypeScript SDKs for the NeoFS decentralized object storage network, adding native tools for JavaScript and TypeScript developers. The neofs-sdk-ts-core package offers shared cryptographic utilities, while neofs-sdk-ts-node delivers full NeoFS API coverage for Node.js, including container, object, and access control operations. Both libraries are open-sourced under the Apache 2.0 license and aim to make NeoFS more accessible for Web3 application development.

On March 16, Neo core developer and R3E Network founder Jimmy Liao announced the release of neo-js v0.1.8, a lightweight TypeScript-native SDK for Neo N3. The package focuses on core functionality like transaction creation, wallet support, and typed RPC access while depending on only two runtime libraries, including COZ's neon-core. It is positioned as a complement to the long-running neon-js SDK and is currently available under an MIT license on npm and GitHub.

Neo has signed an integration agreement with omnichain messaging protocol LayerZero to add cross-chain communication to its EVM-compatible sidechain Neo X. Da Hongfei said on March 16 that TestNet integration should be finished by the end of the month, with MainNet to follow, while talks on a separate Neo N3 integration continue without a set timeline.

R3E Network has introduced the N3Index API indexer for Neo N3, providing structured and raw access to on-chain data via n3index.dev for wallets, explorers, and dApps. Within a two-week period, founder and Neo core developer Jimmy Liao also launched a free, non-expiring .matrix NFT domain system focused on the R3E ecosystem, which is now integrated into the neo3scan.com explorer alongside NeoNS domains.

In the second round of its relaunched Proof of Working initiative, COZ allocated 446 NEO to two Neo N3 ecosystem contributions, a Supabase Sign In With Neo starter kit and the HushNetwork social platform. The starter kit enables wallet-based authentication for Supabase apps, while HushNetwork advanced its privacy-focused social features and introduced Hush Forge for one-click NEP-17 token creation. The Proof of Working program issues weekly NEO distributions decided by the COZ Council for community-driven development work outside traditional grants.

COZ has released a suite of open-source AppKit adapters that let developers on Neo N3 and Neo X configure wallet connections through a single integration. The tools extend earlier WalletConnect infrastructure work and leverage Reown AppKit, which supports hundreds of wallets plus social login and multi-chain authentication features. A Connect Lab demo app is also available to help teams test and implement these adapters across supported networks.

Neo co-founder Da Hongfei has detailed a strategy that positions Neo X as a blockchain optimized for autonomous AI agents rather than direct human interaction, with GAS as the core utility asset. The approach emphasizes infrastructure for agent identity, coordination, storage, privacy, and instant finality, alongside Hong Kong's regulatory environment as an advantage for institutional-facing crypto and AI initiatives.
