On September 22, ETHGlobal announced the finalists of the ETHGlobal Singapore Hackathon. As one of the peripheral activities of TOKEN 2049, there were 310 projects participating in this competition. In the end, 10 projects stood out, including Clarity, Memora, Fill Me Up, etc., involving DeFi, wallets, NFT and other fields. These projects will share the $325,000 prize provided by 31 projects including Worldcoin, Uniswap, Metamask, etc.
This article takes you through these 10 projects in detail.
Clarity
Clarity is a payment gateway that aims to solve the problem of fake reviews by enabling seamless, verifiable on-chain payments and reviews, ensuring transparency and building trust for merchants and users.
Clarity aims to ensure that all purchases and reviews are made by verified real users and not bots using proof of payment and review via Sign Protocol, as well as private identity verification through Incognito operations leveraging WorldID.
Clarity enables any user to seamlessly create a Smart Wallet simply by logging in with Dynamics using Google, without having to know anything about wallets, transactions, or gas. Clarity also provides incentives through tokens.
Memorize
Memora allows users to manage their digital footprints through blockchain-secured NFTs. Users can link various digital accounts (social media, wallet addresses, emails, cloud storage) and set specific conditions for transferring, saving or terminating access rights based on life events such as death, marriage or even job changes.
With the help of AI monitoring agents, the platform can continuously track account activities and trigger automatic actions when predefined events occur. Memora allows users to store digital content and assets that can be unlocked by someone previously set by the owner.
Fill Me Up
Fill Me Up allows users to approve funds on a single chain, and when the user's Gas on any chain is insufficient, the balance will be automatically filled with these pre-approved funds. This ensures that users only spend the minimum amount of money to maintain sufficient Gas on all chains, eliminating the hassle of manual replenishment.
The project uses an intermediary contract to which users approve funds. The service monitors the gas levels of users who have set funds. When a user runs low on gas, the service calls the intermediary contract, which transfers some funds to itself using the approved limit. It then swaps and bridges the funds to the chain with the low funds. Since the contract can only transfer funds to the same user address on another chain, users can maintain full control and security and are not at risk of losing their assets.
Angpao Money
The utility Angpao.money can create âmagicâ links that allow anyone to receive cryptocurrencies effortlessly.
As an entry-level solution, Angpao.money is unique in that it is the easiest to use: no additional features required, no installation required, just click on the link.
Angpao.money is implemented by the technologies of ENS, The Graph, Worldcoin, Reown, and Nouns Dao.
Spirit
Geist is a decentralized website builder for DAOs that supports trustless zero-knowledge proof deployment, private previews, and collusion-resistant voting, allowing DAOs to collaborate at scale and making the internet more trustless.
ENS-based whitelist gateway for private previews. Geist hosts website previews on IPFS encrypted behind the gateway website. Users need to visit the gateway and sign with a wallet to access. With the CCIP protocol, Geist deploys a hybrid resolver capable of resolving both on-chain and off-chain data. The resolver will resolve the cryptographic hash in the TXT record of the target domain and attach the token to the custom gateway for authentication. If the user is whitelisted, the UI gateway will redirect the user based on the decrypted ipfs hash response.
Geist votes on site proposals via MINA and creates build proofs for each site build via trustless deployment using ZK proofs based on MINA.
Hanseek
Hanseek is a blockchain-based video review platform that aims to ensure that reviews are authentic, restore trust in restaurant recommendations, and reward authentic, trustworthy recommendations. Reviewers are verified using World ID, ensuring that only real people can post reviews. Reviews are stored on Flow's blockchain, ensuring transparency and preventing tampering, while Dynamic supports seamless login, allowing users to easily participate in the real world.
Users can browse short video reviews, book restaurants directly, and trust the recommendations they see. When users visit restaurants based on their reviews, creators are rewarded, and restaurants attract more customers through verified, trusted feedback.
fheProxies
fheVPN (Proxy) leverages the power of Fully Homomorphic Encryption (FHE) to provide secure, anonymous web browsing through a decentralized Proxy as a Service (PaaS) model. Node operators can set up proxy nodes in different regions and set prices for access. The details of these nodes are encrypted using FHE, ensuring that only authorized customers who have paid through the Fhenix network can access them. Even in the event of an IP leak, unauthorized users are blocked by a whitelisting mechanism. This eliminates the need for a password as the client's IP is encrypted and shared with the node provider to be whitelisted after payment. This creates a secure, anonymous browsing experience powered by blockchain.
fheVPN (proxy) leverages the Fhenix network to integrate fully homomorphic encryption (FHE) with smart contracts, providing secure access control. The backend allows node operators to deploy proxy nodes and encrypt their details using FHE, ensuring that sensitive data such as IP addresses remain confidential. Clients pay on-chain using the ethers.js library, and their IP addresses are encrypted through the Fhenix network. This information is only visible to node providers who have whitelisted the client for access.
SQUIDL
Squidl is a privacy-focused platform that makes managing payments simpler and more secure. With private static payment links that can also be used as ENS addresses, it's easy to accept cryptocurrency or credit card payments while ensuring that nothing can be traced.
The platform provides seamless integration with various blockchain networks, including Ethereum, BSC, Morph, Linea, and Flow EVM, allowing users to accept a variety of payment methods.
In addition, credit card payments can be converted to USDC and bridged to BSC, ensuring convenience and privacy. Squidl also has the ability to bridge funds to the Oasis Sapphire network, where transactions are completely untraceable. Squidl's flexibility also extends to asset transfers, including NFTs, soul-bound tokens, and liquidity tokens.
Snow
Nifi is the first Web3-based secure WiFi access portal that uses token and NFT authentication on the blockchain to seamlessly authorize users by verifying fair use of digital assets.
Nifi integrates blockchain, OpenNDS, and Raspberry Pi to create a decentralized private portal that authenticates users using ERC20, ERC721, and ERC1155 tokens.
Marina Royale
Marina Royale uses Uniswap V4 hooks to implement gas-free lottery functionality and is optimized for mobile devices through Telegram. Users can create lottery pools with built-in referral and liquidity incentives.
Key features include:
Risk-based lottery LP pool allocation
Multiple winning scenarios based on pool size
Uniswap V4 integrates curve-based liquidity and a built-in referral system
Pyth Network, for secure, decentralized entropy generation
Unlike no-loss lotteries, the project's system offers different expectations for players and liquidity providers. Players have a chance to win a huge jackpot, but may lose their principal. Liquidity providers profit from unwinning lotteries and benefit from a built-in referral system, potentially making more than traditional yield-generating protocols.
