[RFC] Onboard Lagoon Finance ETH Vault to ETH Mainnet (Higher Risk) Vault

Summary

This RFC proposes integrating Lagoon Finance’s ETH vault into the ETH Mainnet (Higher Risk) vault in the Lazy Summer Protocol.

Adding the Lagoon ETH vault will diversify ETH yield strategies, leverage Lagoon’s institutional-grade ERC-7540 vault infrastructure, and expand Lazy Summer’s yield-generating sources with a curator-managed approach that has demonstrated strong performance across $84M+ in platform TVL.


Motivation

  • Expand yield sources – Provides exposure to Lagoon’s curator-managed ETH strategies, adding a complementary ETH yield stream alongside existing ARKs. Lagoon’s ERC-7540 standard enables asynchronous deposit/withdrawal management optimized for institutional-scale operations.
  • Institutional-grade infrastructure – Lagoon is built on Safe with Zodiac modules, providing battle-tested security infrastructure. The protocol has undergone 7 security audits and manages $300M+ in platform TVL.
  • Attract new user types – Engages current Lagoon depositors and institutional allocators who prefer the ERC-7540 standard, deepening penetration into the ETH staking ecosystem.
  • Increase TVL – Adds an ETH ARK supporting Lazy Summer’s ETH vault growth objectives on Mainnet.

Protocol Overview

About Lagoon Finance

Lagoon provides open, general-purpose, secure vault infrastructure to build and scale on-chain yield products. Key features include:

  • ERC-7540 Standard – Curators manage deposits and withdrawals asynchronously, enabling sophisticated yield strategies that aren’t possible with synchronous vault models
  • Built on Safe – Leverages battle-tested Safe infrastructure with Zodiac modules for security
  • Curator Model – Professional curators deploy capital across DEX LP, money markets, yield-bearing assets, and governance incentives
  • 7 Security Audits – Extensively audited codebase
  • $84M+ TVL on Ethereum – Demonstrated market adoption

Yield Strategy

The Lagoon ETH vault deploys capital across:

  • Liquidity provision on DEXs
  • Lending on money markets
  • Yield-bearing and fixed-income assets
  • Points, airdrops, and governance incentives

Risk Considerations

  • Curator dependency – Performance depends on curator decision-making
  • Multi-protocol exposure – Underlying strategies span multiple DeFi protocols
  • ERC-7540 complexity – Asynchronous model adds operational complexity
  • Smart contract risk – Standard DeFi protocol risks apply

These risks are appropriate for a Higher Risk vault classification.

Risk Assessment: 9Summits Flagship ETH and USDC Vaults on Lagoon

9Summits operates two actively managed flagship vaults on Ethereum mainnet using Lagoon’s ERC-7540 asynchronous vault infrastructure, as described in Lagoon’s vault architecture overview. The proposed vaults are:

  • 9Summits Flagship ETH Vault (9SETH) with WETH as deposit asset (see the 9SETH vault page).
  • 9Summits Flagship USDC Vault (9SUSDC) with USDC as deposit asset (see the 9SUSDC vault page).

Both vaults pursue discretionary, multi-strategy DeFi yield (DEX LP, money markets, leveraged fixed-income style positions, depeg-redemption trades, points and airdrop farming, and cross-chain positions observed on DeBank), as stated on their site and documentation.

At a glance (as of February 26, 2026)

Parameter 9Summits Flagship ETH 9Summits Flagship USDC
Deposit Token WETH USDC
Receipt Token 9SETH 9SUSDC
Total Deposited $8.35M $5.81M
Expected Settlement ~2 days ~2 days
Management Fee 0% 0%
Performance Fee 20% 20%
Infrastructure Lagoon ERC-7540 Lagoon ERC-7540

Backing

Depositors provide the vault’s deposit token (WETH for 9SETH, USDC for 9SUSDC) and receive a receipt token (9SETH or 9SUSDC) representing a claim on the vault’s managed portfolio, as shown in the deposit and vault terms sections of the 9SETH vault page and the 9SUSDC vault page.

Because Lagoon settles deposits and redemptions using an off-chain valuation workflow, the settlement price depends on the NAV posted by the valuation actor and later applied during the settlement cycle, as described in Lagoon’s valuation and settlement documentation. Combined with the ~2 day settlement window, this introduces settlement-rate risk and rebalancing path risk. On that basis, BA Labs does not recommend onboarding these vaults into either LR or HR fleets.

Collateral breakdown and collateral exposure

Both vaults are discretionary and can allocate across multiple downstream DeFi venues within the curator’s permitted execution scope, consistent with Lagoon’s separation of vault accounting from strategy execution (see Lagoon’s vault architecture overview). The disclosed strategy categories include:

  • DEX liquidity provision
  • Money market lending and borrowing
  • Leveraged fixed-income style positioning
  • Depeg-redemption trades (LST or LRT instruments for the ETH vault, stablecoins for the USDC vault)
  • Cross-chain positions, as visible on DeBank: DeBank for 9SETH and DeBank for 9SUSDC

DeBank also indicates that the 9SETH vault deposits into 9SUSDC, implying the vaults are not isolated and may be materially correlated in risk.

The remaining positions include protocols such as Aave, Spark, and Morpho, as well as Avant and Yield Basis. Given the discretionary mandate, portfolio composition can shift over time and can introduce leverage, depeg exposure, and cross-chain risk that are not bounded by immutable, on-chain allocation constraints.

Redemptions and liquidity

Lagoon vaults process deposits and withdrawals via settlement cycles rather than instant withdrawals, with both 9SETH and 9SUSDC showing an expected settlement time of about 2 days on their respective vault pages: 9SETH and 9SUSDC.

Lagoon terminology also makes clear that settlement can only satisfy withdrawals if the curator has sufficient assets available, which creates a liquidity dependency on the unwindability of the strategy book, as defined in Lagoon’s terminology.

What this means for Lazy Summer: Lagoon positions behave like T+about 2 day liquidity rather than instant liquidity. Redeems must be pre-staged, capital remains exposed during the settlement window, and claims can be delayed beyond the expected window if positions cannot be unwound in time. This introduces rebalancing path risk and a stressed-liquidity failure mode that is incompatible with LR fleet assumptions and can also impose material operational stress on HR fleets.

Governance and roles

Lagoon separates the vault contract from the strategy execution layer and supports curator setups such as Safe with Zodiac Roles Modifier or MPC, as described in Lagoon’s Safe and Zodiac Roles Modifier guide.

Lagoon’s valuation flow is two-step: a designated valuation actor posts a valuation, and settlement is finalized through curator actions, as described in Lagoon’s valuation and settlement process.

For 9SUSDC, Lagoon displays role assignments on the vault page, including:

  • Owner + Curator: 0x6d46e28ab34622d9a39d0f306a37a8dc270951af
  • Valuation Manager: 0x9dcbfe1be475f3e3dd1204108b4f5d80ff1e9ddb (see the 9SUSDC vault page)

For 9SETH, role assignments include:

  • Owner + Curator: 0xc868bfb240ed207449afe71d2ecc781d5e10c85c
  • Valuation Manager: 0x9dcbfe1be475f3e3dd1204108b4f5d80ff1e9ddb (see the 9SETH vault page)

Owner and Curator being the same address implies no separation between the governance role and the execution role. The same entity controls both vault parameters and strategy execution.

Lagoon vault logic is upgradeable via an opt-in proxy with explicit upgrade delays described in Lagoon’s upgradability and opt-in proxy documentation.

Risk assessment and conclusions

Core risks

  1. Discretionary, actively managed strategy risk

    • Both vaults rely on manager discretion across multiple DeFi venues, including leverage-capable positions and event-driven components (see the 9SETH vault page and the 9SUSDC vault page).
    • This already places both vaults outside typical LR fleet requirements.
  2. Off-chain NAV and settlement-at-NAV risk

    • Settlement uses a NAV posted and then finalized via Lagoon’s settlement process rather than an automatically computed on-chain mark, per Lagoon’s valuation and settlement documentation.
    • For Lazy Summer, this means that deposits and withdrawals can clear at a manager-supplied NAV that can lag market reality during volatility, creating tracking error versus on-chain marks and enabling timing-driven behavior around settlement cycles. This does not align with LR fleet standards, and we consider it risky even for HR fleets.
  3. Asynchronous redemptions and liquidity dependency

    • Expected settlement is about 2 days, and withdrawal satisfaction depends on curation address liquidity availability, per Lagoon’s terminology and the vault pages for 9SETH and 9SUSDC.
  4. Upgrade and platform risk

    • Vault logic can be upgraded via an opt-in proxy with a minimum 24 hour and maximum 30 day delay, per Lagoon’s upgradability documentation.
    • Lagoon provides an audit index and publishes Nethermind Security reports, as linked from Lagoon’s audits page, including NM-0432 and NM-0534. Audit coverage does not necessarily extend to each curator’s operational security.

Recommendation

BA Labs does not recommend onboarding either 9SETH or 9SUSDC into current LR or HR fleets. The primary disqualifier for both fleet types is Lagoon’s settlement process: deposits and redemptions only clear after the Valuation Oracle posts an off-chain-computed NAV on-chain and the curator calls settleDeposit or settleRedeem, as described in Lagoon’s valuation and settlement documentation. This makes settlement timing, NAV accuracy, and redemption satisfaction dependent on off-chain curator actions, which is incompatible with the operational assumptions of both LR and HR fleets. In addition, these vaults exhibit material centralization risk: Owner and Curator are the same address, and the valuation role is also controlled within the same operational domain, meaning a single entity effectively controls strategy execution, settlement finalization, and the valuation inputs that determine settlement outcomes. For LR fleets, discretionary active management, leverage-capable exposures, and cross-chain positions are additional disqualifying factors.

Note: This assessment is based on publicly available documentation and the vault pages as of February 26, 2026. Material changes to vault configuration, roles, or Lagoon infrastructure require reassessment.

I’m in support of this proposal. The yield numbers are hard to ignore — 200bps above benchmark on a 30D basis is a meaningful edge, and the underlying allocations to established protocols like Spark and Aave give me reasonable confidence that this isn’t just chasing risky returns.

On diversification, adding Lagoon’s curator-managed strategy genuinely complements the existing ARK lineup. Lazy Summer benefits from not having all ETH yield concentrated in the same strategy types, and this brings a different execution model to the table.

That said, I do take the centralization concern seriously. Having Owner and Curator as the same address is not ideal — proper role separation is a basic safety expectation in DeFi, and I’d like to see 9Summits address this before or alongside any SIP moving forward. It doesn’t have to be a blocker, but it should be a condition.

Overall, I vote Yes — with the expectation that the team takes the BA Labs feedback seriously and works toward better role separation and transparency around the valuation process.
