finally completed this, btw guys this code is old and does not work as its web3 things move fast here so, i would recommend using gemini and antigravity for this course. If you wanna check mine here is my contract address: ST377XPCB05QYXH8JS49CJXJ5SFXWJS63ZCT9MZDX.stream. Paste this in stacks and u will see a working defi protocol.

done! worked! some things are already changed though, had to deal with that e.g No more use of createPrivateKeys in stacks/transaction , etc. I will advice others just learning to leverage the use of AI as a guide to stay up to date in this course.

i guess you meant you "didn't" use "unwrap-panic" so that in case of an error the code won't just panic without showing us what went wrong explicitly unlike "unwrap"... Reference to refuel function summary- "First, we use the stream-id to fetch the actual stream tuple from our mapping. We use unwrap-panic here because if the stream-id is invalid, the code will just panic and throw an error, which is what we want."

This is really good! i am hooked!

For anybody here after me, make sure to install the exact packages version from the github repo to not run into an error
