We made this decentralized application (dApp) to help developers learn about Web 3 protocols. It uses TypeScript, React, and various smart contract languages.
Following along with the Figment Learn Pathways, you will build up a simple web client using various JavaScript APIs to interact with different blockchain networks. Each protocol is slightly different, but we have attempted to standardize the workflow so that you can quickly get up to speed on networks like Solana, NEAR, Secret and Polygon!

Clone the repo and install the dependencies with yarn:
git clone https://github.com/figment-networks/learn-web3-dapp.git
cd learn-web3-dapp
yarn
If you encounter any errors during this process, please join our Discord for help.
To make use of the Pathway content, you will require a DataHub account and a valid API key for the protocol you wish to access via DataHub's infrastructure. Sign up for a DataHub account and verify your email address, then visit the DataHub Services Dashboard and select the protocol you want to access. You will then be able to copy your personal API key.
You will need to create a new file in the project root directory ~/learn-web3-dapp/.env.local, copying the contents of the existing .env.example file.
Your API key needs to be pasted into .env.local so that you can authenticate your connections with DataHub.
Start the Next.js development server on the default port 3000 with:
yarn dev
If your setup requires a specific port to allow inbound requests, or if you already have a service running on port 3000 - you can also specify a port with the --port flag:
yarn dev --port 3001
Once the server is running, you should see similar output:
yarn run v1.22.10
$ next dev
ready - started server on 0.0.0.0:3000, url: http://localhost:3000
info - Loaded env from ~/learn-web3-dapp/.env.local
info - Using webpack 5. Reason: Enabled by default https://nextjs.org/docs/messages/webpack5
event - compiled successfully
You can now view the running application at http://localhost:3000 (or whichever port you specified)!
We sincerely hope you enjoy the Pathway content and thank you for using learn-web3-dapp to learn about blockchain protocols 🚀
