**Cross-Chain with Trustless Bridges** **Track 3 - DeFi/NFT/DAO. Metamask, Web3.js, randomness opcode, [FlyClient bridges](https://harmony.one/horizon) vs rollups, BLS aggregated signatures** * * * The first hackathon theme is _Cross-Chain_ with our trustless, on-chain bridges. The 4 tracks — Liquidity, Middlewares, DeFi/NFT/DAO, Platform — emphasize the current **product-market fits** of decentralized applications but across multiple chains. Developers can make use of Harmony’s rich ecosystem: a cross-chain API for aggregation and asset pools; Ethereum-compatible indexing, names, and toolkits; and, unique technical features including randomness opcode, on-chain delegation and aggregated signatures, FlyClient bridges, and fast state sync with message gossips. Besides advancing these cross-chain infrastructure, there are also many product ideas that can take advantage of our trustless bridges. For example, building **arbitrage bots** with our partner Hummingbot or integrating stablecoins and saving products with our Terra bridge. Harmony has also launched Bulletproof and Poseidon Hash functions for privacy coin mixers like Tornado Cash.

#### Track 3: Cross-Chain - “DeFi/NFT/DAO” In this category, we are looking for developers to build applications that bring the most utility to Harmony mainnet in the form of transactions, users, total value locked.

For Fixed Income we have listed a number of lending and staking protocols designed to give token holders a return which can provide a fixed income. Interesting areas include staking derivatives, lending protocols, and other financial derivatives. ### Research and Repositories - Decentralized Finance - [See Track1 - Cross Chain Liquidity for Aggregation, Arbitrage and Fixed Income](https://talk.harmony.one/t/track-1-cross-chain-liquidity/1969/3) - Lending - [AAVE](https://aave.com/) - [docs](https://docs.aave.com/portal/), [github](https://github.com/aave/aave-protocol) - Staking Derivatives - [Lido](https://lido.fi/) - [docs](https://docs.lido.fi/) [github](https://github.com/lidofinance) - Yield Strategies - Scheduling Infrastructure - Non-fungible Tokens - [NFT as a wallet profile](https://www.christies.com/features/10-things-to-know-about-CryptoPunks-11569-1.aspx) - [ONE World: Geospatial NFT Marketplace](https://github.com/harmony-one/bounties/issues/48) - [Smart Markets for NFT’S](https://hbr.org/2007/10/the-art-of-designing-markets) - [NFT Marketplace](https://davinci.gallery/) - [timeless: moment nft & curator dao](https://medium.com/timeless-economy/timeless-partners-with-harmony-to-launch-nft-moments-ec7b404cc893) - [1wold: geo spation nft](https://github.com/harmony-one/bounties/issues/48). - [crypto domains](https://docs.google.com/document/d/16SNMAWQcW3LiluVOrlozer2h-odGWXJ0XXtPOwag1lw/edit) - [dazuck’s community vs tokens](https://twitter.com/dazuck/status/1380160252621041665?s=12) - Games based on VRF Randomness - [One Degen](https://onedegen.herokuapp.com/) - [Nano Royale](https://nanoroyale.com/) - [freyala](https://www.freyala.com/) - [defi kingdoms](https://defikingdoms.com/), - [geriatrics gaming](https://geriatricsgaming.com/) - Decentralized Autonomous Organizations - [Harmony Vision](https://harmony.one/deck-q3) - [Hackathon Tracks](https://github.com/harmony-one/hackathon/issues/16) \* [Harmony Talk Dao](https://harmony.one/talk-dao) - [DAO 101](https://creators.mirror.xyz/862A5rBtKX3BC8eEircDnGwPIJJTJ33hn-MvnukByPc) - [DAO Landscape](https://coopahtroopa.mirror.xyz/_EDyn4cs9tDoOxNGZLfKL7JjLo5rGkkEfRa_a-6VEWw) - [A pre-history of DAO’s](https://gnosisguild.mirror.xyz/t4F5rItMw4-mlpLZf5JQhElbDfQ2JRVKAzEpanyxW1Q) - [Dragon Kill Points Whitepaper](https://poseidon01.ssrn.com/delivery.php?ID=116093024026074126083093001064003018057036007092012071117085093029013001100084085075097052026037044058003004095084094115088022022093092011016120081114071091019054066095105031082102029025028124127093031000123019079124023124106096108015108126106121&EXT=pdf&INDEX=TRUE) - [Duck Dao](https://duckdao.io/) - [Coordinape](https://coordinape.com/) - [docs](https://docs.coordinape.com/) - [Tribute DAO](https://tributedao.com/) - [intro](https://medium.com/@OpenLawOfficial/introducing-the-tribute-dao-framework-3f2f0ed50d62) [docs](https://tributedao.com/docs/intro/overview-and-benefits) - [Openlaw github](https://github.com/openlawteam) - [tribute-contracts](https://github.com/openlawteam/tribute-contracts) - [tribute-ui](https://github.com/openlawteam/tribute-ui) - [Moloch github](https://github.com/MolochVentures/moloch) ### Additional Developer Links - [Developer Docs](https://dev.harmony.one/) - [Getting Started](https://docs.harmony.one/home/developers/getting-started) - [APIs](https://docs.harmony.one/home/developers/api) - [Dapp Templates and Tutorials](https://docs.harmony.one/home/developers/showcases/dapp-samples-on-harmony) - [Codebase](https://github.com/harmony-one) - [Horizon trusted bridge smart contracts](https://github.com/harmony-one/ethhmy-bridge) ![68747470733a2f2f6d69726f2e6d656469756d2e636f6d2f6d61782f373230302f312a576672576f7061363159424b5368516d6f7875726a512e6a706567](https://canada1.discourse-cdn.com/flex035/uploads/harmony1/original/1X/f2eb300edb30be7e5fa09de947dc2fe6c4b49231.jpeg) **Ready to build?
