About
The problem it solves The problem it solves is that the legacy paper certificate or centralized sys certificate to an new era... using EDU chain network, making the original document upload into IPFS and then the hash value is shown up to the user with the certain id that matches with our db of data with that hash and user id. Then the user connects the wallet in the home page and then they'll see the available files in the home page, then the user connects to EDU chain and the user clicks on mint and then they sign the transaction with minimal gas fee on EDU chain. Then as it's ERC-721...it's a unique thing and then added under the contract I deployes CertificateNFT(CNFT). And then it's there forever on chain and then no one can tamper it....
How it's made
Challenges we ran into The gas fee was freaking high at some cases so That was difficut when i deploy contracts and then i got 2-3 faucets and then sorted it out
