The problem Lu# solves
--> Decentralised crowdfund removes the need of mediators processing transactions and cutting their fee off of the amount raised
--> Transaction fees is very very less(less than 1000 times) on aptos blockchain(move contracts) as compared to more mainstream Ethereum and Bitcoin
More details:-
Ultra-Low Gas Fees
Aptos blockchain offers significantly lower transaction costs compared to Ethereum and other chains:
- Creating a campaign: ~$0.002 USD

This means more of your money goes to the actual cause, not transaction fees!

Challenges we ran into
There were MANY hurdles
--> I was initially using vite for frontend but it had some compatibility issues with Mac so I had to build the frontend on Nextjs
--> The IAM permissions of aws builder account were fuzzy, I could not deploy my website of AWS Amplify or S3, had to settle for just Lambda + Bedrock
--> I deployed a contract with one less field in campaigns and had to deploy another contract which caused compatibility issues in existing campaigns, had to manually fix this
--> everything was so new, I felt lost and stuck all the time, web3 and aws were not my cup of tea but now I feel quite satisfied with my constant efforts and sleepless nights
