Among the 30 winning projects, 5 belong to the infrastructure category, including Deus Ex Securitas that can automatically audit smart contracts using machine learning, Death Star intercepting malicious transactions with MEV frontrunners, Blocksnap for on-chain data snapshot generation, and IdentDeFi that can identify KYC users.
6 projects fall under the DeFi category, including SlowSwap, a MEV-resistant Uniswap V2 fork project, and DustSweeper that can exchange small tokens for ETH. In this field, there are two DeFi projects for NFT assets, namely Bunker.finance, a lending protocol supported by NFT collateral, and Mimicry Protocol for NFT derivatives.
4 projects are in the proof category, including geographic proof, NFT ownership proof, and identity proof. Additionally, there are 5 gaming and metaverse projects and 4 DAO or community projects among the winning entries.
Looking at network construction, nearly 20 projects will be built on multiple chains, with the vast majority on Ethereum or Polygon, and a few on Polkadot, Binance Smart Chain, Harmony, Algorand, Gnosis Chain, Metis, and Arbitrum.

Infrastructure
Deus Ex Securitas: Automated Audit of Smart Contracts with Machine Learning
Deus Ex Securitas can automatically audit smart contracts using machine learning. The NLP model can classify Solidity scripts based on vulnerabilities and even pinpoint which lines of code are susceptible to attacks.
Death Star: Intercepting Malicious Transactions with MEV Front-Runners
Death Star intercepts malicious transactions on the Ethereum chain immediately upon detection, protecting user wallets from hacks and scams.
The specific solution by Death Star involves users whitelisting multiple addresses. When one of these addresses is transferring tokens to a non-whitelisted address, Death Star's MEV front-runner sends a transaction with double gas fees to move all the user's assets to a backup address.
Cannon: Protocol Deployment Management
Cannon is a Hardhat plugin inspired by Docker and Terraform, allowing the configuration of protocol scripts, keepers, and on-chain dependencies for automatic deployment across multiple local or chain environments.
Cannon includes a built-in decentralized package manager (supporting Ethereum and IPFS), making it easy to cover existing development or test protocols. The project's three members are core contributors to Synthetix.
Blocksnap: Tool for Generating On-Chain Data Snapshots
Blocksnap is a tool for easily capturing on-chain data snapshots, compatible only with EVM chains. Currently supports Ethereum, Polygon, Arbitrum, and Optimism.
IdentDeFi: Identifying KYC Users
IdentDeFi uses ZK proofs to maintain user anonymity and identify compliant users, focusing on open, secure, and privacy-protecting compliance checks.
In operation, users undergo KYC once and mint a non-transferable NFT. The protocol can then check if the user holds the KYC NFT to help filter eligible users to use their platform.
DeFi
SlowSwap: Uniswap V2 Fork Resistant to MEV
SlowSwap is an AMM protocol with Verifiable Delay Function (VDF), a Uniswap V2 fork designed to prevent Maximum Extractable Value (MEV) and sandwich attacks. Built on Ethereum, currently live on the Ropsten testnet.
DustSweeper: Convert Small Token Amounts to ETH
DustSweeper allows users to convert various small token amounts to ETH, saving on transaction fees. Built on Ethereum and Polygon, the process involves users approving a series of small tokens in their wallet, then the Taker Bot exchanges these tokens for ETH at a discounted price to deliver to users. DustSweeper is currently in the testing phase and not yet deployed on the mainnet.
DustSweeper is crowdfunding on Mirror, having raised 115 ETH, well surpassing the initial target of 50 ETH. Crowdfunding contributors will receive 34% of the total supply of DustSweeper tokens (DUST) when the DAO is launched.
Bunker.finance: NFT-Backed Lending Protocol
Bunker.finance is a decentralized lending protocol backed by NFT collateral, built on Ethereum, using Compound's pool mechanism to facilitate instant lending without borrowers and lenders waiting for a match. Bunker.finance also integrates with Yearn v3's USDC and WETH vaults to earn interest on funds not currently lent to borrowers.
Bunker.finance plans to integrate with Rarible's NFT indexer service to display NFTs that users can deposit. After Rarible supports CryptoPunks, CryptoPunks NFTs will be the first collateral supported by Bunker.finance.
Mimicry Protocol: Derivatives Protocol for NFTs
Mimicry Protocol (MIME) aims to provide users with a DeFi derivatives protocol for NFTs based on Polygon, utilizing Chainlink oracles to map NFT prices. Positions are represented by ERC-721 token Mimics.
Users can deposit MIME collateral to mint Mimics, which record data such as the type and quantity of collateral deposited, the type of NFT traded, direction, opening time, pledge rate, and more.
ExchangeIt: Decentralized Free Trade Market
ExchangeIt is a decentralized free trade market based on Polygon, enforced and incentivized by smart contracts. Users can list items and quotes, where item prices are supported by Chainlink EA with GPS, and disputes and bad actors are decided by DAO governance. Currently live on the Polygon Mumbai testnet.
Regarding the specific trading process, sellers submit item names, location, description, contact information, price, minimum hosting quantity (MATIC), and a 6-digit code. Buyers then submit quotes and need to send more than the minimum hosting quantity of MATIC specified. Sellers can only accept one quote and host the MATIC, and once the seller accepts the quote, the contract is locked. Buyers and sellers meet to exchange goods and unlock the contract with the code. Furthermore, both successful buyers and sellers receive token rewards after a successful trade.
Skew You: Yield Arbitrage
In the Arbitrum-based Skew You, users deposit funds into a vault that automatically allocates these funds to the highest-yielding arbitrage positions. The V1 version will utilize Tracer Perpetual Pool tokens on Balancer and perpetual futures on GMX. However, users will still need to discern fund risks post-launch.
NFT
Supercool: NFT Creation Tool and Tokenized Social Engagement Engine
Supercool is a no-code NFT creation tool and tokenized social engagement engine. Users can draw or create pixel art on Supercool, starting from templates, then mint and share on Twitter. Currently released on Polygon.
Furthermore, Supercool extracts user engagement data from Twitter through its engagement engine, such as retweets, likes, and comments, then proportionally distributes its social token Supercool Social Token (SST) to users.
Games & Metaverse
Arena-Verse: Virtual World for Athletes
Arena-Verse aims to create a virtual world for track and field athletes. In this metaverse, arenas and facilities are created for athletes, along with insurances and financial products, utilizing Web3 tools for governance. Arena-Verse aims to provide fair rewards and economic benefits to athletes.

Specifically, ZKmaps enables users to prove their location within geographical geofencing boundaries without revealing exact locations using ZK snarks. Use cases include helping POAP DAO verify the decentralization of procedure funds, confirming if a location is within a state or city, ridesharing, location-based NFT minting activities, and more.
Note: Geofencing is a software feature that uses GPS or RFID to specify geographical boundaries.
