### 1. Overview:

Remove **all** remaining Arks across every Fleet that still has a registered Ark set, leaving each Fleet as a buffer-only, withdrawal-only ERC-4626 shell. This is the second and final round following SIP2.59 / SIP7.3, which removed only the legacy Arks already at deposit cap `0`. Each network is handled in its own sub-SIP and its own Governance vote (SIP2.60.1–4).

* * *

### 2. Motivation:

SIP2.59 and SIP7.1/3 removed the legacy, zero-cap Arks and re-opened the paused Fleets for withdrawals. The Arks that remained were the _active_ set, the ones that could not be capped to `0` at the time, or that were still in productive use.

With deposits capped at zero across the protocol, the Fleets withdrawal-only, and the Labs Co. winding down, that active set no longer serves a purpose. Every registered Ark remains counted in NAV and is therefore still part of the share-price surface the July 6 exploit abused; it is also strategy and accounting surface that will not be actively risk-managed once the transition completes. Removing all of them leaves each Fleet maximally simple and permissionlessly redeemable.

Unlike SIP2.59, **no `setTipRate(0)` is required**, tip rates were already zeroed in the first round.

> _ **Connected RFC:** [[RFC] Neutralize All Vaults to Withdrawal-Only Shells](https://forum.summer.fi/t/rfc-neutralize-all-vaults-to-withdrawal-only-shells/897)_

* * *

### 3. Specification:

Each sub-SIP is one on-chain proposal covering one network, executing `removeArk()` for every remaining Ark on that network’s Fleets. Two sub-SIPs carry additional, explicitly disclosed actions:

- **Sonic (SIP2.60.3)** performs a bounded Raft loss-socialization on two Silo Arks _before_ removing them, because residual bUSDC share balances are blacklisted from sweeping and block a clean deregistration.
- **Mainnet (SIP2.60.4)** additionally `unpause()`s `LazyVault_LowerRisk_USDC`, one of the exploited Fleets, so its final Ark can be removed.

Proposals originate on the Base governor and, for non-Base Fleets, relay via LayerZero to the destination-chain timelock. Per-network details, addresses and Ark lists are in the sub-SIPs below.

* * *

### 4. Risk Assessment:

Mechanical/low-change for the Ark removals with [@Recognized\_Delegates](https://forum.summer.fi/groups/recognized_delegates) sign-off on the DAO-managed Fleets. Key points:

- Removing an Ark takes it out of the Fleet’s active set and out of NAV, closing the donation/price-manipulation vector identified in the post-mortem. Each Ark is divested to the Fleet buffer as part of deregistration; withdrawals remain available throughout and share price is preserved.
- Unlike round 1, these Arks are **not all at cap `0`** , so we should confirm per Ark that the position can be exited cleanly without slippage, queued/async redemption delays, or stranded balances. Two known cases: **Origin-weth** on `LazyVault_HigherRisk_WETH` (async OETH redemption, the market must be exited before execution) and the two **Sonic Silo Arks** (handled via the socialization sequence in SIP2.60.3).
- **No user funds are moved** by these votes beyond making them withdrawable. The only value transfers are the two small Sonic sweeps (9,830 and 640 bUSDC shares) disclosed in SIP2.60.3.
- The Mainnet `unpause()` re-enables withdrawals on an exploited Fleet and is gated onchain by the minimum pause time; it should be confirmed consistent with the SIP1.7 market-withdrawals process and the SIP1.9 Merkl distribution.

* * *

### 5. Voting:

Each sub-SIP is voted independently.

> If **YES** - execute that network’s cleanup.

> If **NO** - leave those Fleets unchanged.

#### [SIP2.60.3] Remove all remaining Arks incl. Raft loss socialization (Sonic Fleet)

| Parameter | Value |
| --- | --- |
| Fleet | `LazyVault_LowerRisk_USDCe` |
| Network | Sonic |
| FleetCommander | `0x507A2D9E87DBD3076e65992049C41270b47964f8` |
| Raft | `0x2a828B0E5cB549eE568923E815D9A781b6f4F018` |
| Arks removed | 2 |
| Extra actions | 10 Raft calls (2 × socializeLosses + permission flips) |
| Unpause fleet | No (not paused) |
| Set tip rate | Already `0` |
| Risk mgmt | ba-risk-managed |
| Execution | Base governor → LayerZero (`dstEid=30332`) → sonic timelock `0x4c32A28AD95deaBc06bF7C83AdEbCF6fe6721ED9` |

##### Actions (in order):

For **`Silo-market_8-usdce-146`** (`0x42aade02…`), token bUSDC-8 (`0x4e216c15…`):

1. `Raft.setSweepableToken(ark, bUSDC-8, true)`
2. `Raft.setNonSweepableToken(ark, bUSDC-8, false)` — lift blacklist
3. `Raft.socializeLosses(ark, [bUSDC-8], 0xB0F53Fc4e15301147de9b3e49C3DB942E3F118F2)` — sweeps **9,830 shares**
4. `Raft.setNonSweepableToken(ark, bUSDC-8, true)` — restore blacklist
5. `Raft.setSweepableToken(ark, bUSDC-8, false)` — restore whitelist

For **`Silo-market_20-usdce-146`** (`0x5c841955…`), token bUSDC-20 (`0x322e1d53…`): 6–10. The same five-step sequence — `socializeLosses` sweeps **640 shares**

Then on the Fleet: 11. `removeArk(Silo-market_8-usdce-146)` 12. `removeArk(Silo-market_20-usdce-146)`

##### Arks removed:

`Silo-market_8-usdce-146`, `Silo-market_20-usdce-146`

##### Notes on the socialization:

The permission changes are **symmetric and self-restoring** — each Ark’s sweep flags are flipped, one `socializeLosses` is performed, then both flags are restored, so the end state equals the start state. Each `socializeLosses` names exactly one Ark and one token; no other Ark or token is touched. The amounts are stranded residue, not user principal.

> **To confirm before posting:** the recipient of the swept shares, `0xB0F53Fc4e15301147de9b3e49C3DB942E3F118F2`, should be identified explicitly in this post (it is not a Fleet, the Raft, or the timelock).

##### Voting:

> If **YES** - execute the above for LazyVault\_LowerRisk\_USDCe on Sonic (socialize the two stranded bUSDC residues, then remove both Silo Arks).

> If **NO** - leave the Fleet unchanged.

* * *

### Still outstanding for full coverage

- **`LazyVault_HigherRisk_USDC` (Mainnet, exploited)** not covered by any payload in this batch. Its Ark set needs enumerating and a proposal raising, either here or on the SIP1.X track alongside SIP1.8.
- **HyperEVM Fleets** (`0x252E5Aa42c1804b85b2ce6712cd418A0561232Ba`, `0x2cC190fb654141DfBEaC4c0f718F4d511674D346`) understood to have no remaining registered Arks after SIP2.59.10–11

I am supportive of the overall actions outlined in this SIP and the subsequent sub-SIPs. Removing the remaining Arks, leaving each Fleet as a buffer-only, and neutralizing the Fleets is the sensible next step in completing the protocol’s wind-down.
