On September 22, Hong Kong time, ETHGlobal announced the projects that entered the "finals" of the 2024 Singapore ETHGlobal Hackathon. With the successful convening of the TOKEN2049 event, this hackathon was not as deserted as the current market. There were more than 300 participating projects, and finally 10 projects stood out.
Judging from the shortlisted projects, payment has become one of the most important tracks. We may not understand it in China where mobile payment is already well developed, but in other countries and regions where payment infrastructure is not perfect, payment has become one of the important application scenarios for cryptocurrency to land first.
The 2024 ETHGlobal Singapore competition has announced the shortlist. A total of 10 projects stood out from 310 entries. This article will introduce these outstanding projects.
Clarity: Web3 Payment Gateway Protocol
Clarity is a Web3 payment gateway project that targets fake reviews and transaction transparency issues. It combines Sign Protocol and World ID authentication to ensure that every review comes from a real user, not a robot or multiple accounts. It also provides token rewards to actively participate users to encourage them to share real product feedback.
In order to enhance the credibility of merchants, Clarity creates an ENS address for each merchant, allowing users to identify and trust the merchant's information. In addition, Clarity provides a simple smart wallet creation function, and users can log in only through Google.
These measures can create a more trusted payment and review environment for merchants and consumers, thereby reducing the impact of false reviews on business reputation and revenue.
Awards:
The Graph - Best New Subgraph Grand Prize
Sign Protocol - Best Overall Application & Best Consumer Application
Worldcoin - Best Use of World ID 2nd place
Memora: Digital Asset Management Platform
Memora is a digital asset management platform that aims to protect users' digital footprints through NFTs and provide secure and flexible digital asset management services. Users can link their various digital accounts, such as social media, email, and cloud storage, on the platform, and set access rights and operation conditions based on major events in their personal lives (such as death, weddings, or job changes). Its core function is the time capsule NFT, which can securely store users' digital content and assets and ensure that the preset beneficiaries can obtain access after a specific event occurs. The platform is also equipped with AI agents, which are responsible for monitoring users' account activities in real time to confirm whether the preset events have occurred and ensure the smooth transfer of assets. This design enables users to effectively manage their digital legacy by automatically transferring assets and information to designated relatives and friends through smart contracts after a specific event occurs.

Fill Me Up: Multi-chain Gas Fee Management Tool
Fill Me Up is a multi-chain gas fee management tool that helps users automatically manage gas fees on different chains. Users only need to pre-set funds on a certain chain, and the system will monitor their gas fee usage on all chains. When the gas fee of a chain is insufficient, the system will automatically extract it from the approved funds and transfer it to the chain that needs to replenish the gas fee. In this way, users can ensure that their transactions will not fail due to insufficient gas without manual operation, while also maintaining secure control of their assets. This method effectively simplifies the process of users managing gas fees.

Angpao Money: On-chain “red envelopes”
Angpao.money is a tool that simplifies the process of receiving cryptocurrencies. Users can send crypto assets by creating a "magic link". Specifically, the "magic link" means that the sender first deposits funds into a smart contract, customizes a link, and then shares this link with the recipient. After the recipient clicks the link, they can choose to connect to an existing wallet, or log in through social media to create a new wallet. Finally, they only need to sign to receive the funds, and the whole process does not require any gas fees.
Awards:
The Graph - Best Substream Grand Prize

NiFi: Cryptocurrency-based WiFi access portal
NiFi is a cryptocurrency-based WiFi access portal that allows users to connect to WiFi using cryptocurrencies or NFTs held in their digital wallets, rather than using traditional methods such as mobile phone numbers. This approach makes authentication more convenient while avoiding common problems in traditional WiFi logins, allowing users to access the network more easily.
NiFi supports tokens such as ERC20, ERC721, and ERC1155 as access credentials to verify user identity. Through pre-authentication and forwarding services, the system determines whether the user can access the network. NiFi said that this token-based approach enhances security and supports a variety of application scenarios, such as pay-per-use network usage and airline WiFi access obtained through NFT tickets, thereby promoting the practical application of DID.

Dynamic - Most Innovative Integration
Marina Royale: Decentralized Lottery Platform
Marina Royale is a decentralized lottery platform based on Uniswap V4, where users can start lottery pools with liquidity tokens without the need for traditional ERC4626 vaults. The platform is designed specifically for the Meme community and users holding utility tokens, allowing them to use liquidity in new ways. Users can participate through an optimized mobile experience, without having to pay any gas fees,
The main features of Marina Royale are risk-based lottery pool allocation and diverse winning scenarios. Players can win prizes by participating in lotteries, but they may also lose their invested capital; liquidity providers can earn income from unwinning lottery tickets and earn additional income through the built-in referral system. The referral system will allocate 20% of the face value of the lottery ticket to the referrer, and the remaining 80% to the liquidity provider.
In terms of technical implementation, the project uses two smart contracts (Lottery.sol and LotteryManager.sol), as well as security entropy generated by the Pyth network to ensure the fairness and predictability of the lottery.
