The current narrative in blockchain toward traditional finance is antagonistic.
We need TradFi to join the ranks of DeFi and build apps informed by your experience in traditional finance.
We know there are many working in traditional finance that are interested in blockchain, but not totally ready to jump in head-first. Many in TradFi are interested because they are frustrated with the constraints, regulations, and policies of traditional finance.
If that describes you, then this hackathon is for you.
Build on Harmony, Bridge to all chains.
Harmony is your open platform for assets, collectibles, identity, governance. Be the ONE to bridge to all blockchains. Harmony is an open and fast blockchain.
Our mainnet runs Ethereum applications with 2-second transaction finality and 100 times lower fees. Harmony’s secure bridges offer cross-chain asset transfers with Ethereum, Binance and other chains.

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.
The second hackathon theme is On-Chain with our social wallets and keyless security. The 4 tracks — Frontends, Web3, Web2, Security — emphasize the consumer experience of delighting the users without worrying about blockchain technology or custody. Wallets are becoming the Web3 portals as a DeFi dashboard for asset swaps and investments, a NFT gallery for collectible editorials and auctions, or a DAO townsquare for governance votes or payrolls. Our hackathon encourages seamless onboarding and incentivized education for smart contract wallets; builders can start from our audited prototypes featuring authenticator-based security and on-chain account recovery.
Composing Web3 contracts and integrating Web2 components is the crossing of the chasm for daily uses. Our wallets should work as a mobile or even wearable client. They can also curate crypto and domain names, work activity and reputations, or even virtual and life moments. Furthermore, the wallets can link your identity on Twitter as social clout, Github as work prowess, or Linkedin as tailored profiles. At this hackathon, cryptography or security researchers can extend our authentication to multiple factors, verify implementations with formal methods, or prototype based on our latest research papers.
Lastly, the third hackathon theme is Cross-Border with fintech and social integrations. The 4 tracks — Gateways, Corporate, Regional, Impacts — emphasize the real-world value for business and communities across countries. Toward unbundling of banks, our developers can replicate many centralized services like fiat exchanges, over-the-counters, credit cards, or even corporate finance. Many global business and most decentralized teams are already facing the pain of scaling beyond tens of teammates and countries — dealing with employee payrolls, retirement benefits, medical insurance, and expense compensations. Fortunately, cryptography primitives like auditable privacy will make accounting and tax compliant for business on public blockchains.
Now is also the prime time to innovate on consumer marketplaces and social incentives on blockchain. Radical markets mean self-assessed taxation and quadratic stakes; mechanism designs focus on revealing true preferences and multi-round auctions. Both on blockchain can make retail loyalty programs or commerce logistics far more efficient — or even bring social changes in the form of basic income and retrospective funding for public goods.
No. Completely free to join and participate in the hackathon.
YES. The only way for blockchain to grow is if new developers enter the industry.
Up to 5 people. No other restrictions - can be any background, any country, or any experience level.
We have zero tolerance policy for harassment and other negative behavior.
• "Harassment" includes but is not limited to offensive verbal or written comments or other online activity related to gender, sexual orientation, physical or mental ability, age, socioeconomic status, ethnicity, physical appearance, race, religion, sexual images, deliberate intimidation, stalking, inappropriate physical contact, and unwelcome sexual attention. Participants asked to stop any harassing behaviour are expected to comply immediately. If participants fail to comply they will be banned from all channels and access to the event.
• All sponsors, judges, mentors, organizers, volunteers and the like are also subject to the anti-harrassment policy. In particular, attendees should not use sexualized images, activities, or other material both in their hacks and during the event.
• Be wise and careful and mindful of the words you choose to use at all times. Be respectful and don’t be a jerk.
• Report all violations anonymously here.
Each submission will be judged solely on the quality of the work completed during the duration of the hackathon. If you use pre-existing code, disclose all information in your submission, indicating what’s pre-existing and what code is new and show how your submission is explicitly different from old work.
First and foremost, we want you to build on Harmony. Preference will go to submissions that utilize the Ethereum-to-Harmony Horizon Bridge and whose applications are focused on DeFi. We'll publish a wish-list of applications we want to see on Harmony in a blog post soon. Of course, all submissions need to be linked to a public Github repository and if, selected, be ready to join demo day and present your submission as a team.
The full guidelines for prizes and grants are in this Github link.
Our team and contributors have prepared sample projects in this repo.
