[SIPS-071] Upcoming Turbo SWETH Cellar Proposal


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


Swell is a growing liquid ETH staking ecosystem (swETH), with an emphasis on vault integrations. As a result, we see a significant opportunity for a collaboration between Swell and Sommelier.

The Turbo SWETH vault will accept ETH as deposit asset, and will LP swETH/WETH on Uniswap V3 and Balancer. The purpose of the vault is two-fold:

  1. Earn competitive ETH-denominated yields by taking exposure to swETH.
  2. Provide an efficient managed solution to liquidity provisioning in the Swell ecosystem.

We believe Sommelier has the opportunity to play the role of DeFi infrastructure that provides support for specific ecosystems. In particular, this vault is being built to serve the needs of the Swell community. The vault will take exposure to the following assets:

  • WETH

and the following protocols:

  • Balancer
  • Uniswap V3
