Silicon Valley was buzzing with excitement from March 24th-26th as developers from around the globe flocked to the OKX Hackathon, hosted in partnership with Google Cloud. The three-day event aimed to push the boundaries of decentralized applications on OKT Chain and with over 200 attendees and 46 teams, the event was a resounding success.

But the OKX Hackathon was more than just a platform for developers to showcase their skills. It was an opportunity for like-minded individuals to come together, share ideas, and collaborate on projects. This sense of community and collaboration was a key factor in the event’s success, with participants learning from each other’s experiences and forming lasting connections.

Over the weekend, the developers were divided into teams and given a specific problem to solve using the OKT Chain. The teams worked tirelessly to build solutions that ranged from supply chain management systems to decentralized finance (DeFi) applications.

Before the Hackathon commenced, we held 5 workshops to orientate builders, introducing them to the OKX ecosystem, products and developer docs.

Workshop 1: Introduction to OKT Chain, (Previously known as OKC (OKX Chain)

OKX Blockchain Architect Jay Meng introduced #OKXChain, diving into architecture, consensus mechanism, functions like EVM, IBC, WASM and gasback . Watch the workshop here to learn more about the OKT Chain ecosystem

Workshop 2: Introduction to New Dev Docs and Running a Node on OKT Chain

OKT Chain Engineering Director Kami Ye brought us through OKT Chain Developer Docs and gave us a walk-through on running a node on OKC (OKT Chain). Watch the workshop here.

Workshop 3: Synthetic USD (SynthUSD) with OKX

Backend Engineer Kody Low gave us a technical walkthrough on how stablesats work, using OKX derivatives for hedging and how one can decouple Galoy’s backend to run stablesats against the chosen crypto backend. Watch the workshop here to understand more about SynthUSD and OKX.

Workshop 4: Introduction to OKX Ecosystem: OkLink, OKX NFT, OKX Web3 Yield, OKX Wallet and OKX DEX

The OKX team introduced some OKX features and tools so that participants and walked them through how to use these features to support their projects. Watch it here to get a better understanding of the overall ecosystem and the products within.

Workshop 5: Login with Unstoppable: A web3 SSO

The Unstoppable team came together discuss what it means to own your identity in web3 and to share a tutorial on how to use Unstoppable and its features. Watch it here

Best part of Hackathons? The Freebies

Hackathon swags from OKX and Google Cloud

One of the many highlights was the abundance of swag and merchandise that was gifted to participants. Attendees were treated to a variety of cool items, including t-shirts, hats, stickers, and water bottles, all designed to showcase their love for the platform. It was a clear demonstration of OKX’s commitment to creating an engaging and rewarding experience for everyone involved, and it left participants feeling excited and grateful for the opportunity to be a part of it all.

Chance to Network with Industry Leaders (Google, OKX, Gitcoin, Nametag)

The lineup for the event was packed with a diverse set of speakers and companies, providing a wide range of perspectives and insights. Speakers from Google, OKX, Gitcoin, Nametag, and Northeastern University shared insights on the future of blockchain adoption, decentralization and more.

In addition to the speeches, there was ample opportunity for participants to connect with industry leaders and other hackers. This networking aspect is crucial for anyone looking to break into the tech industry, as it allows for valuable connections to be made and ideas to be exchanged.

Meet the Winners

Lite OKX bridge

For many gamefi and NFT users, a single purchase rarely exceeds $25. Existing bridges are focused on large payments, which makes them redundant in terms of security and with a high entry threshold (from $30–50). This project proposed technical solutions for bridging small payments and aims to lower the entry threshold for those who want to explore the OKT Chain ecosystem.

Thanks to the Lite OKX bridge, users will be able to transfer $2–5 from USDT on Polygon to OKTC in 1–2 minutes without commissions. This will allow them to access all projects on OKTC in one click. Thanks to the SDK, sites will be able to natively support this bridge and the user won’t have to leave the site.

Hexlink

Hexlink eliminates the need for users to set up a wallet before receiving tokens, making OKT Chain more user-friendly and accessible, encouraging more individuals to participate and drive user adoption of the chain. It also provides greater flexibility and convenience for users who can set up their accounts and wallets at a later time, when it is more convenient for them. This approach encourages more individuals to participate in activities on OKT Chain, thus driving the user adoption of the chain.

OKX Guardian

OKX Guardian is a decentralized and trustless solution for managing a person’s digital assets after their passing, ensuring the execution of the deceased’s wishes without reliance on a third party. While some may opt for a lawyer to handle their will and distribute their crypto assets, there are inherent risks in entrusting private keys to a third party. In the event of a security breach, private keys could be compromised, putting the entire estate at risk. OKX Guardian proposed a decentralized and trustless solution, ensuring that the wishes of the deceased are executed without any reliance on a single individual or institution.

Web3 Ads

A lack of transparency in the advertising marketplace, caused by intermediaries, increases costs for both advertisers and publishers and leads to inefficiencies, distrust, and potential ad fraud. Proposed smart contracts to enable advertisers and publishers to buy and sell directly without intermediaries, increasing transparency and reducing costs, inefficiencies, distrust, and potential ad fraud.

Petreat

Every year, 6.5 million dogs, cats, and other former pets are abandoned or lost and enter shelters. Of all these animals, only 3.2 million are adopted, and many see shelters again after less than a year of finding a new home. In order to provide suitable conditions for animals, shelters need regular donations.

Petreat collects donations from supporters and sends this amount to shelters in need. The project was developed with the belief that a reward system is also crucial to motivate and thank donors for their support. Petreat added a NFT reward system so that supporters receive a unique NFT in return for doing a good deed.

The event provided a platform for participants to learn from each other and collaborate on exciting projects, and the projects created demonstrate the potential of decentralized applications to transform various industries. OKX and Google Cloud’s partnership in organizing the hackathon underscores our commitment to fostering innovation and creating a more decentralized future. Our hackathon demonstrated the power of community, collaboration, and innovation in driving technological progress, and showcased the incredible potential of blockchain technology.
