The 30 winning projects are mainly distributed in the DeFi, infrastructure and metaverse or gaming categories, among which machine learning is used to automatically audit smart contracts, MEV frontrunners are used to block malicious transactions, KYC users are identified through NFT, and small tokens can be exchanged for Innovative projects such as ETH and lending agreements for NFT assets have received a lot of attention.
The 10-day ETHDenver 2022 has officially come to an end. Here, 170+ teams of multiple hackathon participants compete for the top 30 for a total of $1 million in bounties and bonuses, $2 million in investment capital, and an additional 1 million SPORK ZK quadratic prize pool .
Of the 30 winning projects, 5 belonged to the infrastructure category, including Deus Ex Securitas, which can automatically audit smart contracts with machine learning, Death Star, which uses MEV frontrunners to intercept malicious transactions, Blocksnap, an on-chain data snapshot generation tool, and the ability to identify KYC User's IdentDeFi etc.
6 belong to the DeFi category, including SlowSwap, the anti-MEV Uniswap V2 fork project, DustSweeper, which can convert small tokens into ETH, etc. In this field, there are two DeFi projects for NFT assets, namely Bunker.finance, a lending agreement backed by NFT collateral, and Mimicry Protocol, a derivatives agreement for NFT.
From the perspective of network construction, nearly 20 projects will be built on multiple chains, most of which will be built on Ethereum or Polygon, and a few projects will be built on Polkadot, Binance Smart Chain, Harmony, Algorand, Gnosis Chain, On Metis, Arbitrum.
