> \- add wstETH/WETH E-CLP with optimized curve
> \- \[Proposal\](https://forum.balance…r.fi/t/bip-641-enable-wsteth-weth-e-clp-gauge-arbitrum/5828)

### Summary

This is a proposal to enable one uncapped Balancer gauge for a wstETH/WETH E-CLP on Arbitrum with Core Pool status.

### 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](https://help.lido.fi/en/articles/5231836-what-is-lido-s-wsteth)
- WETH is an ERC-20 compliant wrapper of ETH.

* * *

### Motivation

Gyroscope is further expanding on Arbitrum. This pool is replacing a previously deployed E-CLP for the same assets and is calibrated to have a better fitting liquidity shape.

* * *

### Specifications

#### Governance

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.

#### Oracles

- ‘rateProvider0’: wstETH rate provider on Arbitrum: [0xf7c5c26B574063e7b098ed74fAd6779e65E3F836](https://arbiscan.io/address/0xf7c5c26B574063e7b098ed74fAd6779e65E3F836)
- ‘rateProvider1’: WETH rate provider on Arbitrum: 0x00

#### Audits

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](https://dune.com/gyro_finance/gyroscope-e-clps).
- wstETH and WETH already have markets on Balancer and other DEXes, but without the capital efficiency of an E-CLP.

## Value

As per “Motivation”.
