Thanks @chrisb for posting this SIP and clearly laying out the context.

Given the recent events with the Silo 127 market and the substantial bad debt (~$1.48M), as expressed in the [RFC](https://forum.summer.fi/t/rfc-arbitrum-usdc-vault-next-steps-dealing-with-usdx-bad-debt/458) poll, I **support offboarding this market via sweep and Timelock**.

IMO this approach:

- Removes the market cleanly from the Arbitrum USDC Vault, isolating risk.
- Allows any remaining liquidity to be redistributed fairly based on a snapshot at execution.
- Minimizes ongoing exposure and reduces governance burden from trying to manage a compromised asset in the Vault.

I am definitely for (after potential off-boarding) to onboard new strategies and revive the Fleet. Also, I would further consider the comment made by @samehueasyou:

> [@\[RFC\] Arbitrum USDC Vault next steps (Dealing with USDX bad debt)](https://forum.summer.fi/t/rfc-arbitrum-usdc-vault-next-steps-dealing-with-usdx-bad-debt/458/6):
>
> I think that all users within this vault after Nov. 3 should receive additional SUMR tokens, and the users who are left with the bad debt should get the commensurate amount in SUMR tokens. (1.48M)

, or otherwise make sure that a snapshot has taken place and allows the Lazy Summer DAO to reimburse the users that has incurred the loss - in case that the funds will be recovered.

From a risk perspective, this seems to be the **most responsible and transparent path forward** but am curious about thoughts from other [@Recognized\_Delegates](https://forum.summer.fi/groups/recognized_delegates)!
