EIS

Technical Challenges

sequence

EIS registers very large images, and we conducted extensive research on onchain image compression/decompression and SSTORE2
We discovered that the Efficax contract is a suitable contract for forking
However, Efficax is implemented with the Manifold contract, so we forked and adapted it to work with the Zora contract
Currently, image data exceeding 100kb can be registered in the EIS contract

To establish fee streaming for Remix asset creation, we utilized splits
Splits require management of the distribution flow and withdrawal process, which necessitated extensive testing to ensure functionality
Now we have flexible royalty streaming with splits

Integrated EIS full onchain image with Zora Contract as a custom metadata renderer and splits as a royalty recipient
Initially, the image was not displayed on the Zora platform due to:
- Zora testnet web app not functioning properly on Base Sepolia, but it was found to work well on the Zora testnet
- Zora contract needing to emit a URI event to prompt the indexer to fetch the data, which we implemented
Now we have successfully integrated and tested here: https://testnet.zora.co/collect/zsep:0x6cd915072796ad62ff4614d6caa436e6354450b6
