Summary
This SIP proposes launching the USDC Fleet – Mainnet (Higher Risk) vault on Lazy Summer Protocol.
This new vault unlocks higher-yield, higher-volatility strategies for USDC holders by aggregating lending, Farming, delta-neutral, and real-world-credit ARKs that sit one risk tier above the existing Mainnet USDC (Lower Risk) vault. Risk parameters will be finalized by @BlockAnalitica using the more aggressive limits outlined in their prior analysis. See RFC for reference: [RFC] Onboard USDC Fleet – Mainnet, Higher Risk Vault
Motivation
- Unlock new growth – Enables a fresh set of USDC strategies that can realistically contribute TVL toward the $100M+ milestone.
- Broaden user personas – Appeals to funds, whales, and yield-hungry allocators who accept higher volatility, while giving existing users incremental deployment options.
- Expand strategy mix – Integrates ARKs beyond pure lending (e.g., rewards farming, delta-neutral stablecoin positions, real-world credit).
- Strengthen brand promise – Demonstrates Lazy Summer’s ability to curate both conservative and adventurous DeFi yield in one automated interface.

Thanks for posting this, @samehueasyou — fully aligned with the motivation here.
Having a new fleet focused on higher-risk USDC vault is a logical next step for Lazy Summer on our path to $1B+ TVL. It fills a clear product gap and allows us to serve a wider set of users, particularly those looking for higher yield and willing to tolerate more volatility. Love the blend of ARKs across lending, reward farming, and real-world credit.
Looking forward to seeing @BlockAnalitica’s final parameters, and would support moving this to vote soon after that’s in place.

Following the suggested final Arks in this forum post, on the Medium Risk Fleet USDC on Mainnet, we integrated, collected historical data, and ran our risk model. We propose the following as the initial parameters:

We have decided to set euler_swaap_lend_usdc to zero for now, based on the previous analysis of Swaap protocol products.
Also it’s worth mentioning that the current TVL of the Euler Swaap Lend USDC vault is ~$350k at the time of writing, having a very low impact on scaling (and potential APY boost) of the proposed medium risk USDC fleet, thus we believe that if the risk profile of this ARK improves, it can be a subject of reassessment by BA Labs if the SummerFi community requests it later on.
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.
