### **SIP-2.18: Integration of Silo Arbitrum - USDC Vault**

**Summary & Motivation** This proposal is to whitelist the Silo Finance USDC vault at `0x2BA...f1ee` on the Arbitrum network for earn-side deposits. Integrating this vault provides users with a high-yield USDC strategy on a key Layer 2 network, offering a compelling APR and promoting cross-chain diversification for our protocol’s yield offerings. The attractive returns present a valuable opportunity to enhance user earnings.

**Specification**

| Parameter | Details |
| --- | --- |
| **Vault Name (Protocol)** | `Silo Arbitrum USDC Earn` |
| **Network** | `Arbitrum` |
| **Underlying Asset** | `USDC` |
| **Silo Vault Address** | `0x2BA39e5388aC6C702Cb29AEA78d52aa66832f1ee` |
| **Yield Components** | `Native Interest + SILO Tokens` |
| **Reported APR** | `16.8% (11.1% discounted)` |
| **Integration Type** | `Earn-side deposits enabled` |
| **Fleet** | `Lower risk.` |

**Voting** Pending community feedback, this proposal will proceed to a formal governance vote to authorize the integration of this Arbitrum-based USDC vault.

This strategy can bring back solid rates for the Arbitrum USDC Fleet. Good fit, thanks for proposing @halaprix!

The proposed Silo Varlamore USDC Growth Ark for the Low Risk Fleet Arbitrum USDC has been evaluated using our risk model, which incorporates metrics such as TVL, collateral quality, and exposure. Following this assessment, we propose the following initial parameters:

| Ark | Symbol/Vault | maxCap | Max. %TVL | maxInflow | maxOutflow |
| --- | --- | --- | --- | --- | --- |
| siloV2 | varlamore-usdc-growth | 780,000 | 39.00% | 780,000 | 780,000 |

The cooldown period for all Arks in this Fleet is 10 minutes. These parameters ensure the Fleet operates within controlled risk limits while accommodating expected demand.
