Offboard low usage Vaults across HyperEVM, Sonic and Arbitrum (Re-submitted)

1. Overview: As per the RFC; https://forum.summer.fi/t/rfc-offboard-low-usage-vaults-across-hyperevm-sonic-and-arbitrum/818, this SIP proposes to offboard all Fleets/Vaults from HyperEVM, Sonic and Arbitrum through setting deposit caps and fee's to 0.

---

2. Motivation:

Since hitting 200M TVL, the Summer Protocol has struggled with issues within DeFi and users losing trust leaving their capital, as well as the low yields on offer due to the reducing demand of DeFi and leverage in general as the market has struggled since late summer last year (2025). As such, we now have a number of vaults with less than $100k TVL, and with less than 25 active users with > $100 deposited. For this reason, it is suggested to offboard these vaults. Also, with the current SUMR rewards ending on the 10th May, this feels a good time to address this concern, and focus SUMR rewards on those Vaults which drive the most TVL and activity. At present, the vaults in question would only represent 242,000 USD of TVL - less than 1% of the protocols TVL. Should DeFi and the markets start to recover, and activity/demand start to appear, these vaults can easily be reactivated simply by increasing the deposit caps and enabling new or existing markets and the automated rebalancer keepers.

3. Specification:

The following will set all vaults across HyperEVM, Arbitrum and Sonic deposit caps and fee's to 0. For each Fleet, the Timelock Controller on each chain will also be set as Curator role in order to set deposit caps to 0. This will be removed again in a later proposal.
