Arbitrum

Category: Non-constitutional Proposer: RARI Foundation

Abstract

The Rari Foundation is submitting a proposal to jumpstart the growth in the Arbitrum NFT ecosystem. The proposal involves integrating Arbitrum One with the open-source Rarible Protocol, which is an indexer, order book, and SDK powering NFT-based applications, which, once integrated, can be freely and easily used by the Artbitrum builders.

Motivation

The Arbitrum ecosystem is hard for independent developers to build NFT-based applications due to a lack of easy-to-use tooling and infrastructure. Without this support, the developer community will opt for other chains with more robust support for building.

Optimism vs. Arbitrum NFT stats as of July 27, 2023, indicate Arbitrum is not the first choice for the creation of NFT assets or contracts. Source: NFT Scan 3.

The open-source Rarible Protocol is focused explicitly on the NFT use case and will enable builders to develop their next dapps choosing Arbitrum, resulting in bringing in new Arbitrum users and sequencer revenue.

The Rarible Protocol is a trusted choice as it’s community governed, has an easy-to-use API, a comprehensive SDK, and is committed to expanding its capabilities to power innovative NFT use cases. Furthermore, the Protocol is used by Rarible.com NFT marketplace, whose brand and community can be leveraged in raising awareness about Arbitrum venturing deeper into NFT tooling. Such signaling to the market will show that the Arbitrum community is serious about growing its ecosystem and flourishing NFTs. Rarible and the Rari Foundation will promote the integration in a cross-marketing push to ensure the NFT and crypto community knows that Arbitrum is serious about NFT growth. This support will consist of (and shall not be limited to):

• Regular features on Rarible.com 1 top spotlight section (1 million MAU)
• Dedicated social support for the launch on Rarible’s and Rari Foundation’s owned channels (Twitter, Instagram, Discord, 800k+ followers combined)
• Email blasts for the integration (500k+ subscribers)
• Leveraging Rarible’s and Rari Foundation’s press relations
• Potentially a hackathon

This proposal is being submitted outside of the pending grants framework in order to implement the integration asap, as waiting for the grants framework would result in significant implementation delays. As such, the Arbitrum DAO has an opportunity to express its willingness to incentivize ecosystem growth via strategic partnerships.

Rationale

The proposed AIP aligns with the Arbitrum community’s mission and guiding values by enhancing the utility, scalability, and inclusivity of the Arbitrum network. The Rarible Protocol, a decentralized toolset for NFT applications, is open-source and free, mirroring Arbitrum’s commitment to technical inclusivity and neutrality.

By integrating Arbitrum One into the Rarible Protocol, we empower developers to create more complex and innovative applications on Arbitrum. This integration increases accessibility to real-time and historical Arbitrum blockchain data, aligning closely with Arbitrum’s commitment to user-centricity and technical inclusivity.

Specifications

Below is a detailed breakdown of how the integration will take place and the platforms and technologies that will be used.

Rarible Protocol: Integrating Arbitrum One

The Rarible Protocol is a decentralized toolset that allows developers to build NFT applications. It includes smart contracts, an indexer, an SDK, and APIs. The integration of Arbitrum One into the Rarible Protocol will extend these capabilities to the Arbitrum ecosystem, enhancing its utility and inclusivity.

1. Rarible Arbitrum SDK

• The Rarible SDK will expedite Arbitrum application development. By extending the SDK to support Arbitrum One, we will provide developers with tools for interacting with smart contracts, supporting NFT operations like minting, transferring, and burning, and integrating with multiple wallets.

2. Rarible Orderbook & Smart Contracts

• Our contracts, specifically the Rarible Exchange V2, will be deployed to the Arbitrum chain, granting access to our off-chain order book. Certain actions, such as canceling, confirming, updating, or when price changes occur, are on-chain, but orders are created off-chain.

3. Rarible Public API

• With the integration of Arbitrum One, the API will offer extended support for these chains, allowing developers to easily access and interact with NFT data on Arbitrum.

4. Rarible Arbitrum Indexer

• Rarible’s multichain indexer will be able to track and record NFT events on Arbitrum, providing developers with a comprehensive view of NFT activities on Arbitrum.

Steps to Implement

Arbitrum One integration into Rarible Protocol

The first key milestone will be integrating Arbitrum into the Rarible Protocol, which will set the foundation for future milestones involving building NFT applications on Arbitrum.

Tasks: Integration of Arbitrum One chain into Rarible Protocol

• Arbitrum API Integration: This task involves integrating the Arbitrum API into the Rarible Protocol API to support Arbitrum One.
• Node Preparation: A separate node for Arbitrum will be set up for rapid indexing upon approval
• Contract Deployment: The Rarible Shared NFT, Rarible Factory (for creating collections), and Rarible ExchangeV2 contracts will be deployed to Arbitrum for users to interact with.
• Orderbook: Rarible’s order book will be able to store listings, orders, and bids made with the Protocol
• Arbitrum Indexer: Index NFT contracts, ERC-721/1155, ERC-20 tokens, Exchange orders & bids (from Seaport & Rarible).
• Arbitrum support on Rarible Multichain SDK: This involves adding a new blockchain, connectors to wallets, and ensuring functionality similar to ETH/Polygon.
• Debugging and Testing: General debugging of all components will be conducted, along with testing on production with OpenSea orders.
• Build Testnet for Arbitrum: An additional environment for the testnet will be set up, including indexing, reindexing, etc.
