[SIP2.37] Add Extrafi XLend’s USDC Pool to Lower Risk USDC Vault

Governance Summer Improvement Proposals [SIPs]
, , ,
1

Summary

This SIP proposes integrating Extrafi XLend’s USDC Pool into the USDC – Lower Risk vault on Base in the Lazy Summer Protocol.

Following technical review and risk diligence, Extrafi XLend’s USDC Pool meets Lazy Summer’s standards for inclusion. For background, see the discussion in [RFC] Onboarding Extrafi XLend USDC into Summer.fi USDC Base vault.

This integration enhances Lazy Summer’s vault diversification and provides access to yield sources beyond standard [e.g., DeFi lending or staking] protocols.

Motivation

Expand Yield Sources – Extrafi XLend USDC currently offers 8% Supply APY(OP Reward APY + Lending APY), higher than most Base USDC pools, complementing existing vault strategies.

Attract New Users – Extrafi maintains over $100M in TVL, supported by a diverse user base including institutional investors and individual users. Integrating Extrafi XLend creates strategic alignment with Summer.fi while offering additional options for strategy-specific holders and users seeking optimized stablecoin deployment.

Increase TVL – Extrafi XLend USDC currently has a supply cap of 4,000,000, and will continue to increase based on the market. This integration strengthens the Lazy Summer product offering and supports growth goals for the USDC vault family.

I am for this proposal. I know a analysis has not been done by Block Analitica yet, but there has already been an approved vault for ExtraFi “Morpho USDC ExtraFi Xlend vault”. This lower Risk USDC Vault will be a great addition to Summer Fi.
