**Title:** Onboarding Seamless WETH Vault on Base **Author:** yellowknife **Submission Date:** 17-June-2025 initially on Discussions Category **Summary** Onboarding Seamless WETH Vault on Base to be allocated for ETH Earn product on Base **Overview** Seamless Vaults on Morpho provide an optimized approach to yield generation, leveraging Morpho’s permissionless infrastructure and isolated pool design. Designed for users seeking efficient DeFi strategies, these yield-optimized vaults focus on blue-chip collateral markets. Curated by [Gauntlet](https://www.gauntlet.xyz/), a leading DeFi risk management platform, they maximize efficiency and returns while maintaining robust risk controls. **How does the vault works** The Seamless WETH Vault has, at the moment of posting, **Total Deposits 25.36M** and **Net APY of 3.72%**. The vault focuses on optimizing yield and streamlining efficiencies across various blue-chip collateral markets. More info into Gauntlet’s curation approach on the [Seamless Governance Forum](https://seamlessprotocol.discourse.group/t/introducing-seamless-weth-vault/864). **Reference discussion posts/governance votes:** [Forum post link](https://forum.summer.fi/t/rfc-onboarding-seamless-usdc-on-base/130), [Tally vote](https://gov.summer.fi/dao/proposal/65491314778632370636443017166911556492800298470277730363318425150416234103573) **Main Risks** As with other DeFi lending and borrowing protocols, Morpho markets can include bad debt accrual, liquidation risk, and smart contract vulnerabilities. **Specifications** **Vault Deposit Token:** WETH **Network:** Base **Contract Address:** [0x27d8c7273fd3fcc6956a0b370ce5fd4a7fc65c18](https://basescan.org/address/0x27d8c7273fd3fcc6956a0b370ce5fd4a7fc65c18) **Seamless WETH path:** [Link to vault](https://app.seamlessprotocol.com/#/vault-details/0x27D8c7273fd3fcC6956a0B370cE5Fd4A7fc65c18) **Morpho UI Path:** [Link to vault](https://app.morpho.org/base/vault/0x27D8c7273fd3fcC6956a0B370cE5Fd4A7fc65c18/seamless-weth-vault) **Morpho Block Analitica:** [Link to dashboard](https://morpho.blockanalitica.com/base/vaults/vaults/0x27d8c7273fd3fcc6956a0b370ce5fd4a7fc65c18?days_ago=30) **Risk Level:** TBD by Block Analitica ---

Appreciate you bringing this one forward @yellowknife. Seamless via Morpho is a strong contender for Lazy Summer vault integration, and the timing feels aligned with other Base-native ETH strategies present. Looking forward to see an updated classification from @BlockAnalitica. That’ll help [@Recognized\_Delegates](https://forum.summer.fi/groups/recognized_delegates) understand where it fits in our fleet stack (likely Lower Risk, but let’s confirm). Excited to see how the review evolves as it moves toward SIP stage. Let me know if you need any help. Thanks again for pushing this forward! –jensei ---

Really excited to see this proposal for another Seemless market added given the success of the USDC market on the USDC Base Vault we have seen so far. This would also, at the time of writing, be a competive APR at 4.73% with 20M TVL, second only to Origin WETH right now - so would immediately be allocated to when onboarded if the numbers stay the same, boosting this Vaults APR for users. Tagging [@Block\_Analitica](https://forum.summer.fi/groups/block_analitica) and [@Recognized\_Delegates](https://forum.summer.fi/groups/recognized_delegates) for their input. The next voting period should start next Wednesday, 2nd July - would be good to see if we can include it in that one. ---

Thank you for the proposal. Just a small note that on Base there is only a lower risk eth fleet currently. Leaving it to Block Analitica to determine whether this fits that fleet. ---
