Title: Building a DeFi DApp from Scratch: Lessons Learned & Roadblocks

Hey fellow devs! I'm excited to share my journey of building a DeFi DApp from scratch, and I'm hoping to get some valuable insights from the community. I was able to get the app deployed on Rinkeby, but I'm stuck on implementing a scalable and secure interest rate model - any suggestions or resources would be super appreciated.

"Hey OP, I feel you on the roadblocks - I was working on a DApp last year and got stuck on smart contract optimization. In hindsight, using a low-level VM like EVM was a major pain point. Any updates on what solved these issues for you?"

"Hey guys, I feel you on the roadblocks. I tried building my own DeFi DApp last year and had to deal with scalability issues on the frontend. Anyone got any tips on optimizing front-end performance without sacrificing UX?"

 

[FILLrate]

"Yea, I totally feel you on the roadblocks. I was working on a DApp myself last year and ran into issues with smart contract optimization. Ended up hiring a dev to help fine-tune the code, saved me a ton of time and headaches."

 

[Evguenitch]

"Lol, I feel you. I was trying to build a DeFi DApp a few months ago and hit a major roadblock with gas prices. Ended up having to rearchitect the smart contracts to optimize for Polygon and now it's humming along"

"Loved this thread, guys. I just went through a similar experience building a simple yield farming app and learned so much from it. Main takeaway for me was to never underestimate the complexity of smart contract audits - it cost me a pretty penny to fix those pesky vulnerabilities"

 

[gogenn]

"Just chimed in on this thread, but thought I'd share my own experiences with building a DeFi DApp. One major roadblock I hit was optimizing gas costs, which nearly killed me in terms of performance. Has anyone found good ways to mitigate this?"

 

[davidfi]

"Luv how in-depth this thread is getting. One thing I learned the hard way is that proper contract auditing is key, saved me from a ton of potential headaches. Anyone have experience with smart contract gas fees optimization?"

Is Solidity still relevant?

"Been there, done that. One major take away from my own DeFi DApp project was the importance of having a solid team of devs, not just smart contract wizards, but also experienced backend & frontend folk. Still, it was a wild ride"

Should I learn TypeScript?

"Loved the thread, guys. Definitely agree on the importance of choosing the right framework for your DApp. I went with Hardhat and got burned by the gas costs, but the learning curve was worth it in the end."
