In the following guide, we are going to see how to fetch the price of any crypto pair (ex: ETH/USD) from an API on the internet and put it back into a smart contract on the Ethereum Blockchain.

All the terminal commands part of this tutorial were run on a macOS machine. If using Linux, you can use almost all the same commands. However, Windows users may need to adapt OS-specific commands and install apps such as Git Bash — but we can not provide full tech support. If you encounter any issues while following the tutorial, our developers we’ll be happy to help or receive feedback on Slack, Gitter, or Telegram.
