Million Ether Homepage
We'll build a DApp inspired by the Million Dollar Homepage, powered by an auction on the Ethereum blockchain
What You Will Learn
Build a full-stack DApp
Write an auction contract
Deploy and debug the contract
Draw in canvas
Connect Blockchain to the Browser
Withdraw your funds
In this course, we'll build a DApp inspired by The Million Dollar Homepage. We'll build a 1 million pixel page, and each pixel can be colored by placing the highest bid.
In this course we'll walk through every step of writing a smart contract, deploying it, hosting auctions, and connecting it to the browser through web3.
If you're looking to build real, full-stack ethereum Dapps, then this is a perfectly-sized example.
