Registration for GWDC 2026 Hackathon Officially Opens to Developers Worldwide.
As a core component of the Global Web3 Dev Con 2026 (GWDC 2026), the GWDC Hackathon is now officially open for global registration.
Hosted by Web3Labs and co-organized by TRON, Pharos, and Conflux, this year’s hackathon is also supported by leading public blockchains, ecosystem funds, and developer communities. The event aims to bring together the most innovative builders to create functional, deployable, and scalable prototypes across frontier use cases including AI × Web3, payment innovation, and cross-border settlement.
The hackathon has also received joint support from blockchain associations at top universities including The University of Hong Kong, Tsinghua University, Peking University, and Shenzhen University, as well as leading developer communities such as OpenBuild, DengLian Community, TinTinLand, 0xU, and XUEDAO. Together, they aim to build a platform where ideas can make the leap from code to real commercial value.

III. Tracks and Prize Details
Conflux Network Challenge Details
Details:https://drive.google.com/file/d/1nsCIH3KzSsicIKwEoPlYOWAFPP6hNqtG/view?pli=1
Task A:
Develop an x402-based application or tool prototype (PoC) on the Conflux network. Participants may choose to build either a payment product powered by the x402 protocol — such as paid API access or a micropayment system for content — or a developer tool serving the x402 ecosystem, such as an SDK or testing framework. The core goal is to demonstrate how x402 can enable efficient payment interactions on Conflux while showcasing its practicality in AI payment and settlement scenarios.
Task B:
Design and build a prototype based on Conflux and the EIP-7702 protocol that lowers the barrier to blockchain adoption. Solutions should focus on enabling non-blockchain users to more easily complete activities such as onboarding, account creation, and payments on-chain. Creative exploration of account abstraction and extended functionality is encouraged.
Task C:
Build a product prototype on Conflux and its ecosystem that serves cross-border settlement use cases in Belt and Road trade or Chinese enterprises expanding overseas. Participants must identify at least one concrete market need and demonstrate how PayFi innovations, such as stablecoin payments or smart contract automation, can reduce costs and improve efficiency. Real-world creativity is strongly encouraged.
Pharos Network Challenge Details
Details:https://drive.google.com/file/d/1M8rw8_3l994aexJnXem9aJ0A_WGITuQw/view
Task A:
Build an order book DEX or perpetuals protocol that delivers an experience comparable to centralized exchanges in a parallel execution environment. Solutions should include support for limit orders, market orders, and order cancellations, as well as high-frequency on-chain matching, order-priority sequencing, and responsive interfaces showing depth charts and candlestick charts. Perpetuals protocols should also include leverage management, funding rate calculations, and an oracle-based rapid liquidation module. Bonus points will be awarded for effectively leveraging Pharos’ parallel execution capabilities to optimize throughput under high-frequency trading conditions.
Task B:
Design next-generation asset management infrastructure capable of capturing diversified RWA yield opportunities. Teams should develop a composable vault framework aligned with Pharos standards, implement at least one real-yield strategy, support dynamic calculation and charging of management and performance fees, and provide a transparent dashboard displaying portfolio composition and historical returns. Exploration of proof-of-reserves solutions based on zero-knowledge proofs will be viewed favorably.
Task C:
Create a decentralized prediction market with a “Web2-level” user experience. Projects should allow users to create custom event markets, use conditional tokens for trading and automated settlement, integrate mainstream oracle data sources, and include built-in social sharing features. Solutions that leverage Pharos’ high-performance architecture to handle complex prediction logic will receive strong consideration from judges.
TRON Challenge Details
Details:https://drive.google.com/file/d/1oQXySTgbTiRJHi5q_8ayOzry4YCWhQGn/view
Task A:
Build a high-performance merchant settlement protocol on the TRON network. Participants are expected to design a non-custodial settlement system that includes multi-signature revenue-sharing logic at the smart contract layer, a highly reliable on-chain indexing engine and aggregated API at the service layer, and a merchant operations console for finance teams. Particular attention will be given to how automation addresses the disconnect between on-chain data and enterprise financial reconciliation.
Task B:
Develop an intelligent coordinator on TRON to serve as a trusted financial governance middleware layer for AI Agents. This challenge focuses on creating a secure gateway between AI Agents and x402 services, with core features including multi-dimensional payment governance — such as spending limits and allowlists/blocklists — as well as high-frequency micropayment aggregation. The objective is to optimize the cost and efficiency of autonomous AI payments while ensuring fund security.
Task C:
Build an MCP server on TRON to empower AI Agents with on-chain operational capabilities. Participants are required to package the on-chain data interfaces of TRONSCAN or TRONGRID into tools compliant with the Model Context Protocol (MCP) standard, allowing AI assistants to query balances, network conditions, and other on-chain data directly. The focus is on standardized protocol interface packaging and translating complex blockchain data into natural-language-readable outputs.
Prize Pool: TRON x Pharos x Conflux — US$20,000 Cash Rewards
- Champion: US$2,500 × 3
- Runner-up: US$1,500 × 3
- Third Prize: US$1,000 × n
