Hello World! by Polkadot: Take the Challenge

DOT and KSM are now integrated on Gitcoin. To celebrate, we created Hello World! by Polkadot to bring you on a journey of Polkadot development discovery.

By PolkadotOctober 9, 2020

It’s finally here – DOT and KSM are now integrated on Gitcoin!

Gitcoin has integrated the token of the Polkadot (DOT) and Kusama (KSM) network into their tech stack, making us (the Polkadot ecosystem) one of the first full integrations outside of the Ethereum ecosystem.

This is another milestone in our “year to remember” in the Polkadot universe: along with a launch, redenomination, token transfers, and a wealth of great projects joining our community, among other things.

Hello World! by Polkadot

To celebrate our integration on Gitcoin, we are organizing Hello World! by Polkadot, a series of challenges to bring you on a journey of Polkadot development discovery. In addition to interesting ways to expand your skills and explore the Polkadot universe, we’ve got DOT tokens, KSM tokens and some pretty cool swag up for grabs.

There are bounties to appeal to all levels, starting with beginners. And if your heart beats faster when someone mentions Substrate, ink!, Javascript, or dApps, we’ve got a challenge for you, too. Join the event HERE.

The Categories to play for DOT token and KSM

There are 23 different challenges over four categories: Beginner, Intermediate, Advanced and Ecosystem. All come with extensive resources to guide you along the way.

Beginners

Conquer your learning curves and rise to the mission!. Launch a local development chain, explore Westend, begin coding with Javascript, deploy a node – we have all these and more for you to choose from.

Intermediate

Ready to raise the bar? Make a multisig transaction? Update the Pallet Template to include a storage item for a custom struct? Perform a forkless upgrades on a local development chain? If so, this is the challenge level for you.
