HackAtom Seoul 2022

July 29-31 | Hanwha Dreamplus, Seoul

< Introduction >

KryptoSeoul is proud to present its second hackathon in Seoul —the 2022 HackAtom is coming to Seoul, South Korea. Preceding BUIDL ASIA 2022, for 72 hours straight, the HackAtom will host South Korea's best hackers. Teams will compete to take home a diverse range of prizes, rewarded to the best teams that builds the Interchain vision.

​Aside from the hackathon, there will be a series of free, educational workshops throughout HackAtom Seoul 2022 and anyone is free to register and join!

Application Deadline: 11:59pm July 27th, 2022


<General Challenges>

1. Interchain Prize: Interoperability



Build something that pushes IBC forward.


IBC is the path towards a fully interoperable network, reaching even beyond the Cosmos network. Much can still be done and we’re asking you to build something that pushes the IBC mission forward. This could be an application that leverages IBC in a novel way, a new IBC application level packet type, improvements or modifications to lower levels of IBC or implementation in new environments. Surprise us with how interoperability unlocks ingenuity.


  • Your project is using the IBC spec.

  • This includes ibc-go, ibc-rs, hermes relayer, golang relayer, and more.



2. Hub Prize: Interchain Security


Spin up a Consumer Chain that showcases the power of the Cross Chain Validation (CCV) protocol and experiment with the application layer.



Interchain Security allows any Cosmos-SDK chain to be secured by the entire Cosmos Hub validator set and the total market capitalization of the ATOM. This task will give developers the opportunity to experiment with the Cross Chain Validation (CCV) protocol. You are encouraged to play around with Interchain Security and innovate on the application layer. The task itself is open-ended in nature. The main goal is to be create: consider how Interchain Security will reimagine the process of launching a Cosmos-SDK chain and how the Cosmos Hub can evolve as a chain for application development and deployment.


Your project leverages Interchain security design in some way.




3. Application Prize: Cosmos-SDK


Build either a blockchain with the Cosmos SDK, a rewrite of an existing module, or a tool that improves the user experience of developing with the SDK.



The Cosmos SDK allows anyone to easily build a sovereign blockchain that comes feature packed with modules to get your decentralized application started. We are curious to find out what you can do with the SDK. This could be a brand new module to kickstart your own blockchain, a novel redesign of an existing module, or tooling that improves the user experience for SDK developers like yourself.


Your project is using the Cosmos SDK repository or uses a codebase like Atlas, Lens, or any other tool that provides UX improvements to SDK.



<Sponsor Challenges>

1. Osmosis Track: CosmWasm-related challenge




Build a CosmWasm application that interacts with Osmosis AMM using their custom bindings.


Osmosis is the largest deployment of pemissioned CosmWasm, and includes custom bindings to their native AMM modules. People building DeFi applications that want to take advantage of a solid DEX (either as a price oracle or to swap tokens) may be interested to build on this chain.
For this challenge, you should write a CosmWasm contract that uses Osmosis custom bindings to interact with their AMM. The contract should leverage this functionality to produce some useful protocol that would enhance the Osmosis ecosystem. You should deploy the app to the Osmosis testnet and provide a UI.



One of the judging criteria is your imagination and product design, but here are some ideas for inspiration, which you could also use :

  • Maker DAO like stablecoin using Osmosis for TWAP price oracle and liquidation

  • Autocompounder for Osmosis LP shares

  • Futures or options on a token using the AMM for settlement



2. Juno Track: CosmWasm-related challenge


Write a CosmWasm contract that runs on Juno testnet and demonstrates the power of CosmWasm IBC to create a meaningful product-level application (not just R&D).


Juno is currently the largest deployment of permissionless CosmWasm in the Cosmos ecosystem. They encourage many projects to build on their chain and are focused on governance and composability. They are looking at IBC to enable more composability of DAOs and other protocols with other Cosmos blockchains.
For this challenge, you should write a CosmWasm application that runs on Juno testnet and another testnet of your choice. It must leverage IBC protocols to provide novel cross-chain functionality. This must go beyond the contract just calling IbcTransfer to move tokens, and have a meaningful product level application (not just R&D). You should provide a UI or document CLI tooling to interact with the application.


One of the judging criteria is your imagination and product design, but here are some ideas for inspiration, which you could also use :

  • Leverage Interchain Accounts for a DAO to stake assets on a remote chain (that doesn’t have CosmWasm)

  • Write a custom protocol to move NFTs between Juno and Stargaze testnets (both have CosmWasm)

  • Build an “AMM router” that swaps tokens either on JunoSwap (local) or Osmosis (via custom IBC protocol) depending on the best current rate.


3. Evmos Track: Solidity-related challenge


EVM has finally arrived in the Cosmos ecosystem! The successful launch of Evmos mainnet marks a new era of interoperability between Ethereum and our growing IBC gang. The ability to deploy Solidity-based applications and contracts opens the door wide for a new generation of DeFi and dapps that leverage the features of both Ethereum and Cosmos.


The Evmos (formerly known as Ethermint) mainnet was launched roughly three months ago, and we are proud to say that the network is stable and producing blocks every ~1.9seconds!

We are calling upon all Ethereum and solidity developers to deploy and develop on Evmos — the amazing infrastructure is currently a relatively blank canvas waiting for you to fill in with your creative ideas.

Evmos is looking for projects of all ranges, from differing skill sets that you bring. Projects can be as simple utility tools, to much more advanced implementations of exciting features that will be presented by the Laurel Project (make sure to attend the workshop!).

We are structuring our prize pool to allow for developers and projects to fully utilize their creativity: a grand prize of $30K will be rewarded to the most impressive project, and 7 runner-up prizes of $10K will be given (for a total prize pool of $100,000 in Evmos tokens).


Although we are approaching the hackathon with a very open “use your creativity,” un-restrictive track, we would love to see the following:

  • Usage of evmos.js, an integral tool for both EVM and Cosmos SDK usage

  • Applications that leverage IBC transfers

  • Analytics and informative dashboards that utilize both the EVM and Cosmos SDK’s modules

  • Deployment of DAO and governance toolings

  • Toolings and contracts that expand the usage of our Gnosis Safe deployment

  • Extra kudos for devs that utilizes the features presented by Loredana of the Laurel Project (more info will be presented at the workshop)

While the aforementioned is not a strict list of ‘must haves’, special consideration will be given to those that do implement one or more of the suggestions!

Forks of existing Ethereum projects are also welcome, as long as there are modifications that make it unique on the Evmos network.

Outstanding projects may also be invited to apply for an Evmos Foundation Grant.
