We’re happy to summarize the 2-month Crab Online Hackathon and announce our winners! With the total acceptance of 37 submissions, the entries proved themselves a lever for paving the way for building on the Crab Smart Chain.

Let’s review the scoring rules.

Participants should follow the instructions below:

  1. Participants need to build a project on the Crab blockchain and be fully open-source, with repository access provided for judging and testing.
  2. The idea of the submitted project can be generated and discussed in advance, and the use of external open-source tools is allowed, but the core code and function implementation need to be completed during the hackathon.
  3. One participant, whether an individual or a team, is eligible for a single prize.
  4. All of the projects must be submitted with a demo video and a pitch, which should include a demo of the working application.
  5. None of the submitted material content should infringe the intellectual property rights of others.
  6. The submitted code should be complete, readable, and compatible with different devices.


Crab’s technical team and investment agency have formed a judging panel, to make impartial comments on the following dimensions for the projects (for reference only, the judging panel has the final right of interpretation).

  1. Tech innovations
  2. Innovation of the concept
  3. Ecological contribution
  4. Market potential
  5. Code integrity

About Crab Network

Follow Us: [Github] [Website] [Medium] [Telegram] [Twitter]

Crab is a canary network with real economic value for Darwinia, and its positioning is similar to Polkadot’s Kusama Network. Crab Network has won the 22nd Kusama parachain slot! You can check Crab status through Polkadot{.js} , Subscan or Subview.

Crab provides smart contract solutions based on DVM (Darwinia Virtual Machine), which is compatible with the EVM (Ethereum Virtual Machine) paradigm. Therefore, it is easy for projects in the Ethereum ecosystem to migrate to the Crab Smart Chain. (Tips: DVM is built on Frontier with a fully EVM-compatible instruction set and an Ethereum RPC-like external interface.)




As an open cross-chain bridge protocol based on Substrate, Darwinia focuses on the construction of future Internet of Tokens. TG:
