[BIP-620] Enable gauge for wstETH/WETH E-CLP [Gnosis]

PR with Payload


This is a proposal to enable one uncapped Balancer gauge for a wstETH/ WETH E-CLP on Gnosis Chain.

E-CLP’s asymmetric concentrated liquidity profile offers capital efficiency improvements. As per previous arrangements between Balancer and Gnosis this pool shall not bear any protocol fees for the time being.

Protocol description

  • “wstETH is a wrapped version of stETH. […] wstETH keeps your balance of stETH fixed and uses an underlying share system to reflect your staking rewards.” - Lido
  • WETH is an ERC-20 compliant wrapper of ETH.


Gyroscope is expanding to Gnosis Chain.



The Gyroscope Protocol will be governed by a DAO and relevant stakeholder with the full launch on Ethereum. For now, the FTL Labs multi-sig can pause the pool, change the swap fee and set the protocol fee. As a custom pool by Gyroscope, the E-CLP will be controlled by Gyroscope governance upon its launch.



Audit reports by Nethermind, Trail of Bits, and Runtime Verification can be accessed here (the E-CLP is called the “CEMM” in these reports). In addition, the E-CLP code has been live in production on Polygon since November 2022.

Centralization vectors

No centralization vectors. The FTL Labs team’s multi-sig can - currently - pause the pool, change the swap fee and set the protocol fee.

Market History

The Gyroscope Protocol is live on Ethereum since EOY23, with E-CLPs on several other chains. Details available here .


As per “Motivation”.
