Instagram, but the photos are in EIP-4844 blobs. Ephemeral on-chain social.

Alchemy - Best consumer application built with Alchemy Account Kit 3rd place

Project Description

Social media doesn't need to be permanent! Blobs are a great way to have data available for a known period of time while automatically expiring. Gas fees would be paid by advertisers, who contribute funds to a FIFO queue, and have their logo displayed while they're at the top of the queue.

Also, L2's are too cheap, and this helps fix that :)

How it's Made

Alchemy Account Kit v4 for user wallet creation. Viem for on-chain interactions. Next.js frontend eployed to Vercel and leveraging Vercel KV for Redis caching of available posts on-chain. Explored using thirdweb engine for the backend wallet to submit the blob transactions, but found that the only efficient way to move forward was a private key in my env vars 🥴
