I built a Blackjack tip jar Wordpress plugin: https://gitlab.com/bohendo/bjtj

After falling into the crypto rabbit hole, I used this project to teach myself the skills I needed to work full-time in the space. Not knowing how to build something and then figuring out how to build it is my favorite way to learn.

The biggest roadblock was the lack of cryptography tooling available in PHP. I might have written the first working implementation for signing Ethereum transactions in PHP. Luckily, I wasn't on a tight deadline. I had the luxury of time to dig into the standards for efficient crypto & the Ethereum yellow paper to figure out how to use the PHP elliptic curve library to sign a transaction.

It was super satisfying to launch my code to the main chain & have my PHP code correctly sign & send a transaction!
