[SIPS-078] Upcoming Turbo GHO Proposal

[SIPS-078] Upcoming Turbo GHO Proposal


The goal of this forum post is to discuss the upcoming Cellar proposal asking Governance to accept the Turbo GHO strategy.


Aave’s GHO stablecoin launched in mid July and has since been growing in supply, currently at ~$21M. We see an opportunity for Sommelier to optimize GHO liquidity and aid in GHO peg defense.

Sommelier vaults have demonstrated not only an ability to earn highly competitive yields, but also to be highly effective at liquidity optimization. For example, the existing TurboSWETH vault makes up roughly 2% of swETH liquidity while routing almost 40% in volume.

As GHO integrations continue, there will be an increasing set of yield opportunities for the strategy to pursue (e.g. leveraged looping strategies).

The deposit asset for the vault will be USDC. The motivation for this decision is primarily GHO being under peg. If the deposit asset were GHO, the vault would need to sell GHO to LP on Uniswap V3. With USDC as deposit asset, the vault can directly participate in peg defense and profit from GHO appreciation (buying GHO at a relatively cheap price).

This is similar to the rationale for the TurboSWETH vault taking ETH as deposit asset rather than swETH.

The TurboGHO vault will take exposure to the following assets:

  • USDC
  • GHO
  • DAI
  • USDT
  • LUSD

and the following protocols:

  • Uniswap V3
  • Aave V3
  • Aave V2
  • Morpho V3
  • Morpho V2
  • Spark Protocol (sDAI)
