DevPost is a familiar brand amongst developers, especially in the blockchain community. We’re excited to be collaborating with them for this hackathon. DevPost’s community is made up of 900,000 developers and technology professionals. Its community has built thousands of projects on Ethereum, Bitcoin and other blockchains.

When is the Hackathon?

The hackathon will take place from August 9, 2020 (10:00am Pacific Time) to September 28, 2020 (6:00pm Pacific Time). During this period we will schedule community & networking calls and connect teams with mentors to accelerate products. Our goal is to create working products with real users to transform international payments, emerging market finance, and global remittances.

Background and Theme

There are 6 billion people living in developing and emerging countries that account for 60% of the world’s GDP and 80% of global growth since 2008.

People and businesses in these countries face tremendous economic challenges, including:

  • Weak and volatile currencies that are not accepted globally, making it difficult for people and businesses in these countries to store value or initiate global transactions.
  • Limited access to foreign exchange, making it almost impossible to transact globally.
  • Poor access to banking services. More than 2 billion adults do not have a bank account (more than 80% of adults in Africa do not have a traditional bank account). Even those adults who are lucky enough to have a bank account, usually have limited access to Credit.

Builders — we need your help to tackle these challenges

Why Harmony?

Harmony is the ideal solution to solve these problems.

  • Harmony is already in the process of launching two audited stablecoins, BUSD (Binance USD) and Rupiah Token and working to on-board new partners to unlock new markets.
  • 5-second block finality, faster than most other public decentralized solutions in the market.
  • Ultra-low fees.

Our Wish List

While we prefer your application fit with the theme of the hackathon, you are eligible to submit any type of Dapp on Harmony’s mainnet to compete for the lower tier rewards.

Let us be clear — we are not being prescriptive, but here are some ideas you can consider.

Cross-chain interoperability, bridges, & stablecoins

Harmony needs bridges between itself and Ethereum or Bitcoin, so that assets can freely flow. This means we need a way for assets from another chain to be minted/swapped on Harmony via some sort of bridge. Be creative here.

Cross-border finance

Being able to seamlessly send assets (money, etc.) on-chain from one country to another is one of the big opportunities for blockchain. For builders, consider integrating stablecoins with existing e-commerce plugins, cash-back reward systems, and integrations with in-country services or exchange partners.

Potential Ideas:

Integrations with fiat gateways & regional partners

In order to send money from one country’s currency to another requires an exchange of assets. This can be done with many available on-ramp and off-ramp companies with available API’s.
