Kaggle Smart Contract Vulnerability Detection Competition

Kaggle Smart Contract Vulnerability Detection Competition

This competition is co-organized by the DeFiHackLabs operations team and OneSavieLabs, and is planned to launch on Kaggle in Q2 2026. It is built on the open-source project Bastet, a community-maintained smart contract vulnerability dataset and detection workflow framework, and is also supported by an Ethereum Foundation ESP Grant. GCC previously funded DeFiHackLabs, and Anthropic's latest smart contract security benchmark, SCONE-bench, curated 405 real-world exploited contract vulnerabilities from 2020 to 2025 across Ethereum, BSC, and Base from DeFiHackLabs' open-source repository. It is a concrete example of open-source work from the Chinese-speaking security community being directly adopted by a top AI lab. The motivation is simple: more and more AI security tools claim they can detect smart contract vulnerabilities, but almost all of them are closed-source paid products, and there is no public benchmark to evaluate how well they actually work. This competition allows participants to use any method on the same dataset under a shared test setting, with publicly reproducible results, to establish the open evaluation standard this field currently lacks. The dataset and research report will also be fully open after the competition.

OpenRPC

OpenRPC

OpenRPC is an Apache 2.0 open standard for describing JSON-RPC APIs, and it has been in use across the blockchain ecosystem for more than six years. The Ethereum execution layer, MetaMask, Chainlink, Filecoin, Celestia, and Starknet all use it to publish API specifications, and its NPM toolkits were downloaded more than 5.9 million times over the past year. In the JSON-RPC ecosystem, the lack of a specification layer causes a chain of problems: fragmented documentation, APIs drifting over time, fragile cross-team integrations, and repeated duplicated effort. This funding supports two concrete pieces of engineering work: releasing a production-ready Linter and upgrading the test coverage tooling to modern ESM modules, both foundational pieces for the continued evolution of the OpenRPC toolchain.

Primus

Primus

Primus is a Web3-oriented privacy data infrastructure project that combines zkTLS and fully homomorphic encryption (FHE) to make off-chain data verifiable, computable, and interoperable across parties without revealing the original information. The project focuses on long-term problems such as the difficulty of verifying the authenticity of off-chain data in on-chain systems and users' lack of control over their own data in existing data systems. By funding Primus, GCC hopes to support it in providing open-source FHE learning and onboarding materials for Chinese-speaking developers and learners, while continuously advancing technical and performance optimization and leading FHE development in the Chinese-speaking community.

SnarkExpress

SnarkExpress

SnarkExpress is an open-source academic aggregation platform focused on cutting-edge zkSNARKs research. It continuously updates important papers in the zero-knowledge field in native LaTeX-PDF form, covering IACR ePrint, special issues of top international conferences, and periodic research compilations. The platform systematically organizes zkSNARKs research progress to form a relatively stable, continuously updated index and reading portal. In terms of functionality, SnarkExpress provides each paper with a structured abstract, a direct link to the original, and reusable .tex/.bib citation files, making it easy for researchers to read, cite, and build on the work. The platform continues and expands ZK Punk's efforts in paper curation, providing a long-term maintained academic reference resource for zero-knowledge researchers and developers.

Vyper

Vyper

Vyper is the second-largest EVM smart contract programming language after Solidity, securing over USD 4 billion TVL across major DeFi protocols such as Curve, Lido, Aerodrome, and Yearn. Compared with Solidity, it has more built-in security protections and constraints at the language level, such as reentrancy locks, a strict type system, and a simpler syntax, and it is more suitable for Web2 developers transitioning from Python. GCC's donation to Vyper will mainly support the development of the Chinese-speaking community, systematically building a Vyper developer ecosystem through "online co-learning camps + offline roadshow events + community content system."

OSKey

OSKey

OSKey is a fully open-source, non-commercial hardware wallet project that helps everyone create and use trustless, general-purpose hardware wallets. Users can freely choose from thousands of third-party development boards and flash the OSKey firmware to use them as hardware wallets. GCC's support is OSKey's first large donation, which will help OSKey reach a user experience comparable to commercial hardware wallets within a year and provide a foundation for its long-term development over the next ten years.

ZK Punk

ZK Punk

ZKPunk is a community co-created weekly digest of ZKP technologies and papers, helping the community stay up to date with the latest academic and industry developments. Contributors add links and descriptions of the latest ZKP technologies and paper updates through the GitHub repo; after aggregation, the website is updated automatically to publish each new issue, and rewards are distributed according to contribution. Running steadily since January 2024, it has accumulated into a high-quality Chinese-language ZK knowledge base.

zkp2p

zkp2p

The core mission of zkp2p is to bridge the gap between traditional platforms (web2) and decentralized platforms (web3) through privacy-preserving and convenient methods. This includes not only the channels for fiat and crypto currency, but also extends to any digital goods on the internet, such as domain names (the first internet-native real estate), ticketing, in-game items, etc.

Mastodon

Mastodon

Mastodon is a non-profit organization that operates the world's largest decentralized, privacy-first social media network. Unlike corporate platforms, Mastodon's growth is entirely community-driven, with 9.6 million registered users across 10,000 servers worldwide. GCC's donation will help empower local communities, foster connections, and promote digital sovereignty. By simplifying onboarding and enhancing user engagement, Mastodon aims to double its monthly active users (MAU) to 2 million by the end of 2025.

DefiHackLabs

DefiHackLabs

DeFiHackLabs, established in 2022, is an open-source community focused on recreating and documenting DeFi hacks through Proof of Concept demonstrations. With over 500 documented cases and 5,000+ GitHub stars, the community has grown from 10 to 300 active white-hat hackers, dedicated to enhancing blockchain security education.

Liber3

Liber3

Liber3 is a decentralized digital library built on Ethereum using ENS and IPFS technologies, emerging after zLibrary's closure. As one of the largest platforms in the ENS ecosystem with 34% of total traffic, it has enabled the community to mint over 2,800 permanent book records through ENS subdomains. With support from GCC, the project advances toward an uncensorable library with smart contract-based full-text search capabilities and cross-chain integration with Linea.
