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, run on 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.
We are making our Ethereum bridge fully trustless and highly gas-efficient and is among the first cross-chain solutions with FlyClient that connect Proof-of-Work Ethereum and Proof-of-Stake chains.
Harmony is also prototyping research for wrapping BTC as cross-chain collaterals. This approach is not only capital efficient but also fully trustless as on-chain and open-source contracts — a breakthrough in the industry.
Billions of users can earn 10% or more annual returns with crypto assets. But they must stop worrying about seed phrases, device loss, email phishing, phone hijacking
We can secure everyone’s financial future against password breaches, software bugs, platform malware and exchange hacks.
We are bringing the best research called SmartOTP (One Time Password) with air-gapped and composable authentication into production.
Blockchains enable many marketplaces but banking services are the native use.
Finance products within one country are already highly efficient and protected. On the other hand, purely on-chain DeFi solutions without onramp gateways or local distribution have limited impact in real-word economies.
Harmony focuses on bridging high-growth economies, hence CrossFi for cross-border finance.
Over $1,000,000 in prizes and seed funding from Harmony and these Prize Partners:
There are 3 main themes and within each theme there are 4 tracks. Those are listed below.
For each of the 12 tracks, the prize pool is $81,000. The judges will select the following winners and prizes:
Top Prize: $20,000
Second Prize: $10,000
Third Prize: $5,000
Pool Prize: $6,000 divided up for all projects with a qualified submission: a smart contract deployed on Harmony mainnet / testnet. The pool prizes are entirely up to the discretion of the judges.
Each track will then have 4 follow on grants of $10,000 each to give out in the 3 months after the hackathon for any winner reaching any of the goals:
These milestones must be reached by December 31, 2021 before the grants expire.
For each track, there will be a 9-person multi-signature wallet of $40,000 and those signers will give out the 4 grants. The 9 people will be the top 3 winners, 3 from the pool prize and 3 from the judges, Harmony DAOs (community, validator), developer captains, and pangaea captains.
The multi-sig holders will decide on the 4 follow-on grants, though we ask that all follow on grants be posted in the Harmony forum (here) with strong support from the community.
In addition to the 12 Harmony tracks, we are working with Terra, Chainlink, Sushi, Maddock Capital, and Hashkey on a challenge with the following prize structure: $20K for top prize, $10K for second, $5K for pool prize, and 2 follow on grants of $10K to be decided by the prize partners.
### Cross-Chain with Trustless Bridge
a. Liquidity. Harmony Cross-Chain API for aggregation, Hummingbot for arbitrage, fixed-rate w/ Terra’s UST
b. Middlewares. Graph, Crazy.ONE names, privacy-mixer
c. DeFi/NFT/DAO. Metamask, Web3.js, randomness opcode, FlyClient bridges vs rollups, BLS aggregated signatures
d. Platform. On-chain delegation, O(1) sync, RaptorQ gossip
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. (more)
### On-Chain with Wallet Security
a. Frontends. Focus on user onboarding & mobile clients
b. Web3. Curate crypto names + reputations + moments, as DeFi dashboard + NFT gallery + DAO townsquare
c. Web2. Link with Twitter/Github/Linkedin identity, multi-factor biometric/location/device authentications
d. Security. Formal verification, cryptography research
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.

### Cross-Border with Fintech Integrations
a. Gateways. Fiat & credit cards, centralized exchanges
b. Corporate. Accounting & tax compliance, auditable privacy, payrolls/benefits/insurance/compensations
c. Regional. Over-counter services for stablecoins, retail shop loyalty, national distributors, commerce logistics
d. Impacts. Social changes & mechanisms, radical markets
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.

### Venture Introductions and Seed Funding
Harmony has relationships with some of the biggest and active funds available. For certain projects and winners, we are happy to make introductions to our keiretsu of venture relationships for additional funding.
With our partner Dorahacks, projects will receive community matching and potentially also venture capital investor interest from their 60+ investor community.
We are an opinionated Layer 1 platform. As we have relationships with most major liquidity providers and investors in DeFi and crypto, we recommend exploring the following themes to make the most of the hackathon.
Extending Stablecoin Adoption
Beginner to intermediate developers.
Take advantage of TerraUSD native stablecoins to introduce crypto-native experiences: subscription payments and micropayments, yield-bearing escrow, milestone or instant payroll, creative remittance solutions.
Decentralized Asset Management
For beginner and intermediate frontend developers.
Over 20% of users of Mirror are in Thailand. Interact with Terra.js, Mirror.js to build decentralized front ends for Mirror. This is a core priority for TFL to enable censorship resistant asset management across borders.
Crypto Native Financial Primitives
Intermediate to Advanced Developers
Extend primitives available within the Terra ecosystem. For example, DAO treasury issue bonds issuance, revenue sharing agreements, income sharing agreements, DAO creation and management cross-chain liquidity, traunching.
Picks and Shovels
One of the highest leverage opportunities in the ecosystem is to enable other developers and builders. Create indexers, block explorers, and developer facing tooling to fix issues every developer will face into the future.
Theme, "Reduction of the broker / middleman tax in all financial marketplaces"
Preamble: blockchain technologies power is to reduce transaction friction and transaction costs across all marketplaces in a mature and efficient ecosystem. Currently nearly every financial transaction undertaken has a "broker tax" applied to it. Harmony's infrastructure enables that to be materially reduced.
Currently most online businesses, particularly early stage startups and more mature tech businesses with recurring revenue have limited recourse to raise money outside of equity rounds. Typically, equity raises when advised by financial intermediaries charge 5-7% of proceeds. A blockchain enabled Crowdfunding solution for equity in these businesses (ideally native to and utilising blockchain technologies) could significantly disrupt this market by bringing new sources of capital to these businesses. In short, improve access through designing a 2-sided marketplace for equity raises.
Similarly these businesses currently are not able to raise debt. Current solutions are focused on securitising or forward selling revenues linked to recurring contract income.
In short we want you to disrupt online platforms providing marketplaces to forward sell revenues and contract receivables.
Our view is that this would require the Use of a stable coin pegged to the USD in the first instance. This should enable any blockchain participant to put their capital to work for real growth.
The development of price feeds delivered via a decentralized oracle network has facilitated the emergence of DeFi applications at scale. Chainlink current offers a variety of additional smart contract services such as verifiable randomness, fair sequencing services and keepers that are also allowing developers to create new and innovate applications. The concept of decentralized oracle networks outlined in the the Chainlink 2.0 whitepaper outlines a future where different constellations of nodes collaborate to process a wide range of workloads. In similarity to how DeFi projects are composable, we envision a future in which the services that facilitate the emergence of new applications are also composable. The purpose of this challenge is to identify the next generation of smart contract services that can be delivered via decentralized oracle networks to allow developers to create new products, new sources of value and ultimately facilitate the emergence of the next wave of blockchain innovation.
