This meant I could now SSH directly into any of the spot instances to see how they were doing.

I created a KeyPair in AWS, downloaded it, and added a parameter to the CloudFormation template so that I could specify the name of this KeyPair and ensure it gets used by the spot instance Launch Template.

I decided to write some code to SSH into the EC2 Spot Instances to check for errors or a low hash rate. Working out exactly why some instances failed and some didn’t did not fit into the scope of this “pissing about with Ethereum” so I hacked something together. So you probably want to keep this one to yourself. Private key: cb1b8e05e47f4d88de19ad4cc7abe16abba67c3c85586158de0266c6b4a99 (Never share your private key) This can be used to access the Ether held in the wallet. A “wallet” can be boiled down to just a public address and private key like this: You don’t need to sign up to CryptoWalletExchangeBase and upload your identity and wave on webcam to a robot. Enter your Ethereum wallet public address (to receive all that Ether)īy the way, creating an Ethereum wallet is a lot simpler than a lot of websites make it out to be.

I launched the CloudFormation template (that Michael Ludvig had created) in the Ohio AWS region using the recommended g4dn.xlarge instance type. I happened to run this on the 8th May 2021 which (I later learned) was the start of the best few days for Ethereum mining profitability in history.
