EIS

Technical Challenges

Full onchain image registration

• 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

Fee streaming

• 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

Zora Integration

• 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

Technology Used

• Zora Contracts for ERC1155 contract and factory
• Efficax for full onchain image registration
• Splits for fee streaming for creators
• ERC-4883 for Composable NFT
• The Graph for artwork curation
• OnchainKit
• Coinbase Onchain Verification
• Rainbowkit SDK for Coinbase Smart Wallet

Base Integraion

Coinbase Smart Wallet

We integrated Smart Wallet for enhanced user experience via Rainbowkit SDK.

Code is found here:

OnchainKit

We integrated OnchainKit to fetch onchain data such as ENS name and avatar.

Code is found here:

Coinbase Onchain Verification

We integrated Coinbase Onchain Verification for user trust and authenticity.

Code is found here:
