For the second week, I worked on two new challenges from speedrun Ethereum. I worked on Token Vendor and Dice Game challenge. Both challenges were more complex than the previous week's challenges. I learned a lot while attempting to solve them. While solving these challenges, I learned about the caveats and gas costs of executing low-level calls in solidity.

I can feel myself getting more comfortable with writing smart contracts as I struggle with these challenges. I am excited about next week's challenges.

LFG 🚀🚀
