[BIP-384] Migrate Stafi rETH/WETH Gauge [Arbitrum]

PR with Payload


The purpose of this proposal is to kill the stafi rETH/ WETH gauge approved in BIP-339 and approve a new gauge. The new gauge will use both rETH and WETH still, a new rate provider from chainlink, the gauge will still maintain a 10% cap, and the new pool is a composable stable pool v5. The motivation is the same as the original post, to expand Balancer’s vision to be the LSD liquidity destination in the most sustainable ways possible.

Protocol Description:

StaFi is a liquid staked derivatives protocol launched in Q3 2020, with a focus on bringing liquidity to staked assets on Ethereum and other Proof of Stake chains such as Polygon, Solana, and Polkadot. Since launch, the protocol has accrued over $36,000,000 worth of staked assets across 11 tokens, with 3,439 active validators.

Similar to other LSD protocols, StaFi issues a liquid receipt token (rETH) representing your share of ether staked on the Beacon Chain via a permissionless validator set. Deposits are partially covered by validator deposits. The exchange rate between rETH/ETH will gradually increase as staking rewards accumulate, though rETH is not redeemable for the ether principal and rewards until after the Shanghai upgrade.

StaFi has a native governance token with the ticker “FIS”. FIS is freely tradable on a number of centralized exchanges, alongside some decentralized exchanges not inclusive of Balancer. FIS has governance utility and can be staked by validators in the StaFi consensus network.


StaFi currently has an existing rETH-ETH pool on Balancer on Mainnet which has seen healthy growth.

StaFi is looking to expand the availability and liquidity of its staked derivatives, starting with rETH, through Balancer on Arbitrum. Ahead of and after the Shanghai Ethereum hard fork, liquidity and yield on LSDs will be a key competing factor as LSD protocols seek integrations and a broader base of holders.

StaFi is committed to driving value to the veBAL and vlAURA ecosystem by incentivizing pool liquidity via Hidden Hand voting incentives. Deeper liquidity should lead to increased volume and revenue accrual.

Centralization Vectors:StaFi’s rebalancing is done by a bot that is run by the foundation. Presently the bot is not profitable to run, so we would not expect anyone else to run it. However, there is no chance of money being inaccessible as a result of the bot stopping–Just that the bridge would run less efficiently.

Market History: rETH has been a tradable asset since March 2021. Trading has primarily taken place in the aforementioned rETH-ETH pool on Curve. FIS is a liquid asset traded both on top centralized exchanges as well as decentralized exchanges.

Value: StaFi will make its Balancer rETH-ETH pool a primary source of liquidity for rETH on Arbitrum. By bolstering liquidity of the pool, Balancer should gain from increased trading fees.

10% capped gauge: 0xA4DAA3498677D655E359b0Fc83EbDbd8dbF76a50

Transaction Specification:

Add new gauge:

The Balancer Maxi LM Multisig eth:0xc38c5f97B34E175FFd35407fc91a937300E33860 will interact with the GaugeAdderv4 at 0x5DbAd78818D4c8958EfF2d5b95b28385A22113Cd and call the addGauge function with the following arguments:
gauge(address): 0xA4DAA3498677D655E359b0Fc83EbDbd8dbF76a50
gaugeType(string): Arbitrum

Edit: Killing old gauge removed due to the gauge already being killed in BIP-356 migration. Payload has been adjusted accordingly.

FYI old stafi gauge is already killed, so this BIP will only add the new one

Didn’t even realize, much appreciated.
