The problem Pindown solves

The Problem

-> Tampering of documents. Sensitive documents must be made tamper proof.
-> Risks involved in storing and managing documents in centralised storages
-> Absence of a universal plugin for dApps to showcase only selected NFT documents of users.
-> Absence of a reliable tool to validate the issuer and receiver of NFT documents in web3 space
-> Difficulty for organisations to save, manage and deploy their documents over the blockchain network.

How Pindown Solves the Problems

-> Organisations or even individual users can upload their documents to any preferred blockchain network.
-> Uploaded documents can be seamlessly managed and shared by both issuer and receiver.
-> Validity of documents can be ensured by verifying both issuer and receiver (comes under the validation flow)
-> Users can pin-down selected documents to hide them from being shared. (Future scope : This solution can be plugged in by any dApp)
-> Simple user login flow to reduce friction between common users and web3 space.

Challenges we ran into

Some Interesting Challenges we ran Into

• While integrating the WalletConnect feature, an updation in the library created a break in our user sign-in flow where network switching and redirection to the platform wasn't working properly. An updation to the latest version of WalletConnect solved the issue.
• Relayer for auto pay of gas fees: We had to integrate a custom relayer network such that the contract pays for itself. This was a major research we had to do to ensure good UX. Thankfully we were able to tackle this with Openzeppelin defender.
