Enhancing Multichain Governance: Upgrading RARI Governance Token on Arbitrum
Abstract
The RARI DAO seeks to enhance its governance framework by upgrading the RARI token contract and bringing its governance from Ethereum mainnet to the Arbitrum ecosystem. This proposal requests to regirster a custom gateway for a new RARI L2 token contract via Arbitrum native bridge, as only the Arbitrum DAO can implement this change. The custom gateway will enable more efficient governance processes with the upgraded token, reduce user costs, and improve overall accessibility for RARI DAO.
Motivation
RARI DAO is governed by the $RARI token, which when locked in veRARI grants voting access. The current token contract is on Ethereum mainnet and is not upgradable. The RARI DAO wishes to upgrade its governance, a part of which is a token contract upgrade with snapshots and delegations embedded. Only the Arbitrum DAO can however set up the mapping of L1 → L2 token addresses in the custom gateway (which is controlled by Arbitrum DAO) on the Arbitrum native bridge. Here is more information about the topic: ERC-20 token bridging | Arbitrum Docs
Rationale
The RARI DAO multichain governance upgrade is designed to make governance more accessible, by simplifying the UX, reducing gas fees, and enabling new token functions. This aligns with Artbitrum’s commitment to user-centricity and technical inclusivity.
With a custom L2 token implementation we will be able to perform the RARI DAO governance upgrade and move our governance fully into the Arbitrum ecosystem.
Key Terms
RARI token: RARI DAO governance token ($1.95 | Rarible (RARI) Token Tracker | Etherscan
RARI DAO: body governing the Rarible Protocol and RARI chain
Custom L2 RARI token: upgraded and simplified RARI token to be used in RARI DAO multichain governance moving forward
Specifications
RARI token in question ($1.95 | Rarible (RARI) Token Tracker | Etherscan) does not have upgradability nor allows the owner to register in the Arbitrum token bridge router.
As such, we’re requesting a custom L2 token implementation and using the (standard) custom gateway. Lacking the ability to upgrade / owner-register, we are seeking Artbirum DAO’s approval to register the upgraded RARI token to the custom gateway so we can proceed with the custom L2 implementation.
The upgraded token contract was fully audited and can be found here: https://github.com/rarible/protocol-contracts/pull/305.
Token contract was deployed first in tetnests and then to Arbitrum One, and RARI chain (which is on top of Arbitrum One). All contracts were tested manually as well.

Steps to Implement
- Deploy token contracts on Arbitrum and RARI chains (done)
- Security audit of the proposed code change (done)
- Change mapping for L1 → L2 tokens on bridge router and custom gateway (This can be done only by Arbitrum DAO)
