# Initial Parameters for the new Medium Risk Fleets on Mainnet, Low Risk ETH Fleet on Base, and the two new ARKs on the Sonic USDC.e Fleet
Based on our previous assessment of ARKs (see [here](https://forum.summer.fi/t/rfc-the-path-to-1b-tvl-onboard-medium-and-high-risk-vaults-for-lazy-summer-protocol/113/29)), proposed for the Medium Risk ETH Fleet (Mainnet) and Low Risk ETH Fleet (Base), we collected historical data and ran our risk model. This model considers protocol TVLs, debt-backed collateral quality, Lindy score, and other metrics to compute parameters (more details can be found [here](https://forum.summer.fi/t/summerfi-lazy-summer-protocol-initial-fleet-and-ark-parameters-by-block-analitica/76)). We propose the following as the initial parameters:
## Medium Risk Fleet Mainnet - ETH
| chain | fleetAsset | fleetCap | FleetMinimumBuffer |
| --- | --- | --- | --- |
| Mainnet | ETH | 15,000 | 0.37 |
With arks:
| Ark | Symbol/Vault | maxCap | Max. %TVL | maxInflow | maxOutflow |
| --- | --- | --- | --- | --- | --- |
| morpho | morpho\_mev\_capital\_weth | 8,000 | 40.0% | 3,000 | 6,000 |
| morpho | morpho\_gauntlet\_weth\_core | 9,200 | 54.0% | 3,000 | 8,100 |
| morpho | morpho\_re7\_weth | 7,600 | 40.0% | 3,000 | 6,000 |
| euler | euler\_swaap\_lend\_weth | 1,100 | 40.0% | 1,100 | 1,100 |
| euler | euler\_prime\_weth | 44,000 | 70.0% | 3,000 | 10,500 |
| aave\_v3 | WETH | 253,000 | 100.0% | 3,000 | 15,000 |
| compound\_v3 | WETH | 37,000 | 67.0% | 3,000 | 10,100 |
| fluid | WETH | 3,800 | 51.0% | 3,000 | 3,800 |
| spark | WETH | 63,000 | 79.0% | 3,000 | 11,900 |
Note that for the Low Risk Fleets, we previously excluded riskier ARKs (see [here](https://forum.summer.fi/t/summerfi-lazy-summer-protocol-initial-fleet-and-ark-parameters-by-block-analitica/76)), such as Euler Yield, due to significant exposure to Usual USD0++, which we deem unsuitable for that category. We’re now comfortable including them under the new, riskier setup, while putting the emphasis on proper labeling of the riskier Fleets on official SummerFi UI, as well as signaling the importance of making Fleets’ and ARKs’ parameters accessible to end users, all while referring to proposed risk tiers by BA Labs, available below (link to the original post [here](https://forum.summer.fi/t/rfc-the-path-to-1b-tvl-onboard-medium-and-high-risk-vaults-for-lazy-summer-protocol/113/29)).
## Low Risk Fleet Base - ETH
| chain | fleetAsset | fleetCap | FleetMinimumBuffer |
| --- | --- | --- | --- |
| Base | ETH | 4,500 | 0.37 |
With arks:
| Ark | Symbol/Vault | maxCap | Max. %TVL | maxInflow | maxOutflow |
| --- | --- | --- | --- | --- | --- |
| morpho | morpho\_moonwell\_flagship\_weth | 6,000 | 78.0% | 900 | 3,510 |
| morpho | morpho\_gauntlet\_weth\_core | 370 | 37.0% | 370 | 370 |
| morpho | morpho\_steakhouse\_weth | 72 | 35.0% | 72 | 72 |
| aave\_v3 | WETH | 10,200 | 100.0% | 900 | 4,500 |
| compound\_v3 | WETH | 1,280 | 43.0% | 900 | 1,280 |
| euler | euler\_base\_weth | 420 | 37.0% | 420 | 420 |
| fluid | WETH | 1,450 | 45.0% | 900 | 1,450 |
For the potential Medium Risk USDC Fleet on Mainnet, we’ve also gathered historical data and derived the following parameters:
## Medium Risk Fleet Mainnet - USDC
| chain | fleetAsset | fleetCap | FleetMinimumBuffer |
| --- | --- | --- | --- |
| Mainnet | USDC | 20,000,000 | 1,000 |
With arks:
| Ark | Symbol/Vault | maxCap | Max. %TVL | maxInflow | maxOutflow |
| --- | --- | --- | --- | --- | --- |
| morpho | morpho\_gauntlet\_usdc\_frontier | 24,700,000 | 40.0% | 4,000,000 | 8,000,000 |
| morpho | morpho\_relend\_usdc | 52,000,000 | 40.0% | 4,000,000 | 8,000,000 |
| morpho | morpho\_resolv\_usdc | 18,500,000 | 40.0% | 4,000,000 | 8,000,000 |
| morpho | morpho\_mev\_capital\_usual\_usdc | 30,300,000 | 40.0% | 4,000,000 | 8,000,000 |
| morpho | morpho\_smokehouse\_usdc | 45,000,000 | 60.0% | 4,000,000 | 12,000,000 |
| morpho | morpho\_gauntlet\_usdc\_core | 47,000,000 | 60.0% | 4,000,000 | 12,000,000 |
| euler | euler\_yield\_usdc | 36,000,000 | 59.0% | 4,000,000 | 11,800,000 |
| euler | euler\_prime\_usdc | 54,000,000 | 60.0% | 4,000,000 | 12,000,000 |
| euler | euler\_resolv\_usdc | 9,100,000 | 40.0% | 4,000,000 | 8,000,000 |
| euler | stablecoin\_maxi\_usdc | 2,010,000 | 40.0% | 2,010,000 | 2,010,000 |
| aave\_v3 | USDC | 1,050,000,000 | 100.0% | 4,000,000 | 20,000,000 |
| compound\_v3 | USDC | 179,000,000 | 70.0% | 4,000,000 | 14,000,000 |
| fluid | USDC | 9,900,000 | 57.0% | 4,000,000 | 9,900,000 |
| sky | sUSDS | 1,400,000,000 | 100.0% | 4,000,000 | 20,000,000 |
Lastly, for the two additional ARKs proposed in this forum post (see [here](https://forum.summer.fi/t/sip2-4-onboard-additional-silo-arks-into-the-usdc-e-sonic-vault/167)), we’ve integrated Silo V2 Finance into our risk model and gathered the relevant data. Based on our assessment, including these ARKs within this risk category is appropriate. Below is the initial parameter set for these new ARKs in the Sonic Fleet:
## Low Risk Fleet Sonic - USDC.e
Additional Arks:
| Ark | Symbol/Vault | maxCap | Max. %TVL | maxInflow | maxOutflow |
| --- | --- | --- | --- | --- | --- |
| siloV2 | s-usdc-8 | 7,600,000 | 45.00% | 1,500,000 | 3,380,000 |
| siloV2 | s-usdc-20 | 31,200,000 | 40.00% | 1,500,000 | 3,000,000 |
## General Remarks
The cooldown period for all ARKs will be set to 10 minutes. These parameters ensure the fleets operate within controlled risk levels while supporting expected demand. Fleet caps will be increased dynamically as demand grows, and we’ll monitor activity closely to adjust as needed.

Thanks for the parameter breakdown, clear signaling around risk tiering, and appropriate usage of the #Risk category (I have took the initiative to adjust the tags for improved searchability and visibility).
This kind of transparency—both in how **ARKs** are selected and how their limits are derived—goes a long way in reinforcing community trust, especially as we expand into more complex and yield-optimized strategies. The clear delineation between **Low and Medium** risk setups is especially appreciated, as it supports better UX alignment and helps avoid confusion across the UI.
Looking forward to seeing how these new parameters perform in practice and where we might eventually fine-tune based on user behavior and ARK-level performance data.
