This hackathon is part of our long-term Polkadot programme, funded by the Polkadot on-chain treasury. This comes after the successful completion of the first part of the partnership: Polkadot Educate.

After the Hackathon, projects will be able to apply for the 10-week Polkadot Accelerator run by Encode.

To find out more about the hackathon, read the official announcement. Don’t forget to sign up for the Hack Launch Event, happening on Thursday 9th September at 5:30pm GMT+1 — Sign up here.

Hackathon Challenges:

You can view all the challenges in spreadsheet format here.

Polkadot General Challenges (paid in DOT)

Easy: Complete Onboarding Challenges: Complete up to 5 entry-level Substrate tutorials to begin learning how to build with Polkadot and Substrate. Find the tutorials here

  • Prize: $10,000 total: $20 USD per challenge (5 max per person) until $10,000 has been filled.

Medium: Best dApp

  • Prizes: 1st: $3k, 2nd: $2k, 3rd: $1k, Runners up: $500 x 4

Hard: Build a blockchain. Substrate is the framework used to build custom blockchains compatible with Polkadot. In this challenge, build a custom blockchain using Substrate that could eventually become a platform within the Polkadot ecosystem.

  • Prize: 1st: $4k, 2nd: $3k, 3rd: $2k

Astar Challenges

The first 30 submissions per challenge are eligible for the prize. Total pool $3000 in SDN!

  • Build & sync a collator on Shiden Network. Let it run for at least five days. No need to bond SDN tokens and become a collator

More info on collators here.

1st prize: $3000 in SDN

2nd prize: $2000 in SDN

3rd prize: $1250 in SDN

4th prize: $750 in SDN

Shiden Network is the dApp hub on Kusama. In this challenge, build a simple dApp on our testnet Dusty. A nice front-end is very important for users to interact with. Build whatever is on your mind! More information on the challenges is available here.

Phala

Follow the “Hello World” tutorials to complete two challenges. You can get $25 prize for each finished challenge. The first 50 successful submissions are eligible for the prize.

Challenge 1 — $25

Challenge 2 — $25

Challenge 1: In the beginner challenges, we have prepared the tutorials to start a local Phala Network testnet, and run two simple demo DApps.

Challenge 2: Hack on one of the DApps. You can add a tiny new feature and showcase it on the demo frontend.

For the challenge details and how to submit, please refer to:

Build a fully functional DApp on Phala Confidential Cloud.

We don’t limit the scope or type of the DApp. When the hackathon is finished, the Phala team will judge the submission and pick up the winners of prizes:

1st — $3000

2nd — $2000

3rd — $1000

plus $500 for each qualified submission.

A qualified DApp should be useful to solve some real-world problems or bring fun to people. It should also address the unique features of Phala (privacy-preserving, computation-intensive, or with HTTP requests)

For the challenge details and how to submit, please refer to:

Acala / Karura + SubQuery DeFi Challenges:

Build with the Polkadot & Kusama ecosystem’s first and only live DeFi blockchain ($14,000 in Prizes). More information on the challenges is available here.

Challenges

Use the Karura blockchain and SubQuery’s data indexing services to build useful and creative tools, dashboards, or DApps.

$100 to any team who finishes 1 SubQuery warm-up challenge and 1 Karura (Acala) warm-up challenge. The best place to start is by referring to the master Karura SubQuery Project and its GitHub repository.

SubQuery

  • Index the total, average, and median KAR amounts for the transfers that an account has sent or received
  • Index the daily volume, highs, and lows for each trading pair on the DEX
  • For each liquidity pool, what account has contributed the largest total liquidity?

Karura

  • Create a simple custom UI for interacting with the Karura DEX
  • Create a portfolio page for Karura including KAR, KSM, and LP token balances. Include an approximate price of all the tokens in the portfolio
  • Create a webpage to show a user’s kUSD loan with a visual indicator on whether it’s in danger of being liquidated

Build a DeFi bot that can leverage on-chain or aggregated data though SubQuery, and DeFi activity to capitalize on opportunities within the platform.

  • Arbitrage bots
  • Yield farming bots

1st: $2500

  • Eligible for an Acala Grant
  • Access to venture funding
  • Incubation and guidance from Acala/SubQuery devs
  • Karura, Acala, and SubQuery swag

  • Access to venture funding
  • Incubation and guidance from Acala/SubQuery devs
  • Karura, Acala, and SubQuery swag
  • Publicity and promotion by the Acala and SubQuery teams

Karura is a brand new network, so there is a big opportunity to build valuable tools for the ecosystem. Leverage SubQuery’s data indexing services to build a tool based on Karura data.

  • Stablecoin loan monitoring and notification system
  • Dashboard like Zapper.fi for Karura
  • Dashboard like Daistats

1st: $3000

  • Eligible for an Acala Grant
  • Access to venture funding
  • Incubation and guidance from Acala/SubQuery devs

  • Incubation and guidance from Acala/SubQuery devs
  • Karura, Acala, and SubQuery swag
  • Publicity and promotion by the Acala and SubQuery teams

Be the first to build a DApp on Karura. You can use apps.karura.network as a reference example for what’s possible. We are looking for smart, intuitive applications that make DeFi accessible for everyone.

1st: $3500

  • Eligible for an Acala Grant
  • Access to venture funding
  • Incubation and guidance from Acala/SubQuery devs
  • Karura, Acala, and SubQuery swag

Moonbeam

Build a web application using the Staking Precompile Solidity interface that enables users to stake their Moonriver tokens. The ideal application is intuitive and well-designed, and makes it easy for users of all kinds (both people familiar with DeFi and individuals who are new to crypto) to stake their Moonriver tokens.

More information and guidance is available here.

Prize: $2k

Your task, in this challenge, is to create a “one-click” staking application using the Staking Precompile Solidity interface that automatically chooses a collator and nominates (stakes) the user’s desired amount of Moonriver tokens in order for them to earn the highest yield. More information is available here.

Prize: $3k

Interlay (interBTC/Kintsugi) Challenges

Total prize of $2,000

Complete both basic challenges to get an understanding how the bridge works on the testnet at https://bridge.interlay.io/. Even if you want to solve more advanced challenges, we recommend doing these getting started challenges to get a feeling how it works.

Easy Challenge 1: Run a Vault

Easy Challenge 2: Issue/redeem interBTC

  • Get testnet Bitcoin from a BTC faucet
  • Get testnet DOT from the interBTC faucet
  • Issue interBTC
  • Redeem interBTC
  • Submit feedback on the issue and redeem process: https://forms.gle/JXBoRdspbG8pMs3k6

Please be sure to submit both the forms linked above, as well as the Encode official submission form if you do the Interlay Easy challenges. If you do not submit the Encode form as well, you will not receive a prize.

Total prize of $3,500

1st prize: $2,500

2nd price: $1000

We have an interface for Vaults running on: https://bridge.interlay.io/vault. However, Vault operators might want to be able to have custom interfaces and see more information like current prices of Bitcoin, incoming oracle price changes, or see how they compare to other Vaults in terms of BTC locked.

The idea for this challenge is to build a standalone dashboard for Vaults that operators can extend with their own information. You could do this as a browser-based interface, mobile interface, or terminal interface.

Total prize of $3,500

1st prize: $2,500

2nd price: $1000

As with most DeFi systems, it’s possible to make a profit by interacting with the interBTC bridge. It’s possible to automate capturing these profits by using bots. The challenge here is to develop a bot that can capture profits by observing on and off-chain data and execute actions.

You can find more details and ideas about the Interlay (interBTC/Kintsugi) Challenges in their Challenges Documentation.
