Polkadot Hack Finale Prizewinners and Summary

After over 10 weeks, the Polkadot Hackathon has come to a close with a fantastic finale event featuring the 10 best projects pitching for top prizes!

This hackathon was part of our long-term programme in partnership with Polkadot and will be followed up by a special Polkadot-dedicated accelerator.

In our last few hackathons, projects including Euler and Reflexer (amongst others) have gone on to raise large investment rounds following the final! We hope several of this cohort go on to achieve great success as well.

About Polkadot

Polkadot is an open-source network protocol that allows arbitrary data — not just tokens — to be transferred across blockchains. It’s built to connect private and consortium chains, public and permissionless networks, oracles, and future technologies that are yet to be created.

Polkadot facilitates a decentralized internet where independent blockchains can exchange information and transactions in a trustless way via the Polkadot relay chain.

Polkadot is the flagship project by the Web3 Foundation, a Swiss Foundation founded to facilitate a fully functional and user-friendly decentralized web. Find out more here: polkadot.network


This was our eighth hackathon to date! You can check out our previous hackathon summaries below:

How it worked

Students, hackers and researchers had 10 weeks to learn and build projects on Polkadot! We also hosted deep-dive workshops, introducing students and hackers to Polkadot’s technology.


We had a panel of rockstar judges from the Polkadot ecosystem to vote on the winners:

Bryan Chen — Co-Founder and CTO of Acala
Hang Yin — Co — Founder of Phala Network
Jack Platts — Co-Founder of Hypersphere Ventures
Sota Watanabe —Founder of Astar, CEO of Stake Technologies

Finalists and prizewinners

10 finalists were chosen to compete for the top prizes. Here is the list of finalists and winners:

1st Prize ($3k)— Metasave

Metasave: A game-world data protocol for interoperable virtual worlds. Metasave allows actions from one world to cause consequences in another in a transparent, verifiable manner.

2nd Prize ($2k)—Polkadot JS Plus Extension

The developer added new functionalities to the original Polkadot js extension, such as view balances, transfer funds, view as QR code and transaction history.

3rd Prize ($1k)—Phalanx

Phalanx is an alternative crosschain decentralized exchange (DEX) platform focused on privacy.



A Dapp that connects to AMTC6 via AcalaAPI/EVM reads account balances, loans and allows swaps, transfers, loan adjustment and transfer. Reads market coin and loan data.


Krakura is an arbitrage trading bot that leverages market differences between the Kraken exchange and Karura to conduct algorithmic trades. Currently our bot supports trading KSM/USD between the Kraken exchange and Karura.


The PhaPass project aims to demonstrate how we could use the Phala confidential contract feature to build a non custodial and decentralized password manager, embedded in a browser extension.


Metadot is your one stop wallet that supports everything required on the Polkadot ecosystem. From transaction to swaps to governance to integration, anything that the user wants.

Publica Fides

Publica Fides is an attempt at a human-based computation game, inspired by the ESP game, or peer-prediction mechanism that attempts to provide a more transparent fact-checking process for news. In this way, arguments of non-transparency in fact-checking are avoided since this is on-chain. Using human-based computation game, this truth-finding process can be extended to other cases, such as surveys or internal research.


Polkawatch is Polkadot Decentralization analytics. It extracts key staking activity from the blockchain and build an analytical dataset out of it. The dataset is then published in a dAapp to raise awareness about decentralization and influence the staking activity of the community.


Parabase is your solution to create a blockchain or a parachain. With preconfigured pallets from the substrate framework you can now create your very own blockchain or parachain for the Polkadot ecosystem. Parabase not only gives you preconfigured pallets but also encourages developers to create their own pallets and have them used by various developers worldwide. Being one of our products, we have the entire product be developer centric and create easy solutions for developers. We believe in development to become easier and have solutions in one market place.
