Challenges we ran into

Accesing the solana keypair details of other users:
Saving the keypair as a string caused the solana module to throw the error of not being able to get_solders(): which is required to send a transaction.
We overcame it by storing the keypair as an keypair object, rather a string.

Hosting our discord bot:
Manually hosting our discord bot was being a tedious task and hence, we used replit to run our discord bot on web , which provided us with an easy experience of using the bot. Pairing it up with uptimemonitor , lets our bot run 24/7 without any issue.

Smart Contract:
Writing smart contracts on solana is no joke, and using Rust is a real hard task. Writing a smart contract in it.... harder.
Hence we used Sea Horse lang to convert our smart contract from python to rust(though are smart contract is incomplete)

Top up methods using Upi(INR):
We werent able to emulate an web2 payments landing page, and ended up just manually entering data assuming the money is sent.

Topping up sol each time:
While testing in a new wallet, it was a hassle for us to transfer devnet sol from our acc to that account, and hence, we ended up airdropping 2 sol in the new wallet to emulate the transaction

ZDFS validation error:
Uploading files in ZDFS-IPFS using python was causing an unknown Validation Error.
Hence, we used JavaScript to access the IPFS by creating an upload.js and download.js and sending post and get requests and now it works without any error
