Four students from the APU Blockchain and Cryptocurrency Club (APUBCC) — Teh Jun Heng, Chiw Jie Ren, Sam Zhi Jian, and Ng Jian Ming — secured a Chainlink Best 5 spot at the TOKEN2049 Origins Hackathon for their project, Wysiwys; which they developed in 36 hours during the world’s largest Web3 event at Marina Bay Sands, Singapore.

Four brilliant students from Asia Pacific University of Technology & Innovation’s (APU) Blockchain and Cryptocurrency Club (APUBCC) — Teh Jun Heng, Chiw Jie Ren, Sam Zhi Jian, and Ng Jian Ming — stole the spotlight at the TOKEN2049 Origins Hackathon in Singapore, bagging a spot in the prestigious Chainlink Best 5.

Their innovative project, ‘What You See Is What You Sign (Wysiwys)’, earned the talented quartet a RM8,156.80 (USD 2,000) cash prize alongside RM20,392.00 (USD 5,000) in AWS credits to fuel its next phase, bringing the total value to approximately RM28,548.80.

Held at the iconic Marina Bay Sands from 6 to 8 October 2026, the hackathon brought together around 250 top-tier builders. 

Teams faced an intense, pressure-cooker environment with just 36 hours to transform a bold concept into a fully operational product. 

As the official hackathon of TOKEN2049, Origins served as a main highlight alongside the world’s premier Web3 conference, which drew over 25,000 attendees from across 160 countries.

The team tackled one of the most perilous security vulnerabilities in decentralized finance: malicious transaction spoofs. 

Dubbed Wysiwys, their creation functions as a robust treasury payment firewall for the Solana network. 

It directly combats the costly threat of signers unknowingly approving fraudulent transactions disguised behind convincing user interfaces, fake invoices, or lookalike wallet addresses.

To safeguard treasury funds, Wysiwys seamlessly integrated a Squads multisig for organizational authorization, an on-chain Guard program to enforce validation, and a Chainlink Runtime Environment (CRE) workflow to conduct real-time verification before any funds move. 

During execution, Chainlink nodes independently retrieved the stored transaction data from three distinct data providers.

The system automatically cross-referenced destination addresses, token types, transfer amounts, and sanctions databases against the treasury’s security parameters. 

A payment processed only when both human signers and the automated Chainlink review reached total alignment. 

In a live test on the Solana devnet, ten Chainlink nodes successfully achieved consensus — flawlessly approving legitimate payments while immediately blocking spoofed destinations.

Beyond the prize money, the hackathon offered APU students an extraordinary platform at the heart of the global crypto scene. 

“Building live during TOKEN2049 week put our team directly in front of leading protocol engineers, founders, sponsors, and venture capitalists. 

“It firmly demonstrated that APU’s student developer community could ship production-grade security infrastructure against aggressive deadlines,” said Professor Ir EUR ING Dr Vinesh Thiruchelvam, APU Chief Innovation, Enterprise & Sustainability Officer.

“Wysiwys concluded the event not merely as a concept, but as an open-source, fully deployed build complete with a working live demo and verified on-chain evidence of its Chainlink integration.

“Competing on a global stage like TOKEN2049 proved that our technical capabilities can stand shoulder-to-shoulder with top Web3 builders internationally. Securing a spot in the Chainlink Best 5 validates our vision, and with the AWS credits and momentum from this win, we have the resources needed to scale Wysiwys far beyond the hackathon circuit,” the team stated jointly.

This impressive result highlighted both the team’s exceptional technical prowess and the rising trajectory of APU’s blockchain ecosystem. 

Armed with AWS credits and strong momentum, the developers now possess the resources to expand Wysiwys beyond the hackathon circuit. 

APU extends its heartiest congratulations to Teh Jun Heng, Chiw Jie Ren, Sam Zhi Jian, and Ng Jian Ming for brilliantly representing APUBCC on the world stage.
