The problem BlockTime Capsule solves

People can use it for uploading anything that will make future-them experience a gush of nostalgia. This app is meant to used for entertainment purposes. For example, I could upload my journal entry and set the capsule time to be at 5pm on Jaunary 22, 2030. Then I'll get an NFT containig the entry airdropped on said date and time. I will also receive a notification regarding the air-drop. The frontend is deplyed immutably to Valist.

Challenges I ran into

Uploading to IPFS and pinning the uploaded data. I fixed it using ThirdWeb's React SDK.
