[RFC] Deploy SUMR Rewards to NEW Arbitrum USDC Vault

1. Summary:

Following the execution of SIP1.1.1 and the removal of the Silo susdx/usdc (127) market from the Arbitrum USDC Vault (SIP2.39), the newly launched USDC Arbitrum vault does not currently accrue SUMR rewards.

This RFC proposes extending SUMR rewards to the Arbitrum USDC vault to ensure consistency with other vaults and incentivize usage.


2. Context & Motivation:

  • The Arbitrum USDC vault is now live onchain and operational.

  • SUMR rewards historically support vault adoption and usage while promoting participation in Lazy Summer Protocol.

  • Other vaults currently have ongoing SUMR emissions, and this vault should align with them.

Objective: Extend SUMR emissions to the Arbitrum USDC vault with a 60-day schedule, matching other active vaults (expiring 09.02.2026).


3. Proposal:

Reward Parameters:

  • Vault: USDC Arbitrum Vault

  • SUMR Emissions per day: 5,239 SUMR

  • Duration: 60 days

  • Total SUMR Emissions: 314,325.33 SUMR

  • Start Date: Immediate upon execution

  • End Date: 09.02.2026 (aligning with other vaults’ reward schedule)

Mechanics:

  • Rewards will be distributed via the standard MERKL mechanism currently used for Lazy Summer Vaults.

  • Adjustments to emissions or duration can be proposed by governance if usage patterns or risk considerations change.


4. Open Questions:

  • Should governance consider different emission rates, or is a straight alignment with other vaults preferred?

  • Any feedback on potential risks specific to Arbitrum USDC usage before extending rewards?


5. Next Steps:

  1. Community discussion and feedback on this RFC.

  2. Align on proposed SUMR per day and duration.

  3. Promote to SIP stage and vote for execution.


6. Informal Support Indicator:

  • [YES] - promote to SIP
  • [NO] - needs more discussion

Thanks @jensei for the proposal. I am in full support of extending SUMR rewards to the new Arbitrum USDC vault. The proposed 60-day schedule aligns perfectly with our other active vaults. Please correct the typo in the proposal section (End Date should read 2026, not 2025) and let’s move this to a SIP vote.
