It took us two days to brainstorm what we could build. Once we decided and began working on the contract, we quickly realized that implementing a bonding curve was much more challenging than anticipated. You need a strong understanding of integrals and how price action can affect the curve.

With some confidence from our research on curves, we started implementing a quadratic bonding curve. However, this approach failed due to numerous overflow errors in our tests. After further research, we discovered Bancor's formula used in their AMM and adapted it to suit our needs. Unfortunately, this process took us eight days.

Finding the right Indexer was also challenging, we tried Envio, SubQuery, and Shovel before finally deciding to use Subsquid.
Subsquid lets us use the same PostgreSQL database as we use in our front-end making it easier to aggregate and make joins.

On the other hand, integrating Appkit and Wagmi was incredibly easy. It only took me two hours to incorporate everything into our Nextjs project. Kudos to the WalletConnect and Wagmi teams!
