[BIP-375] ankreth/(steth/Boosted Aave v3) Gauge [Arbitrum]

PR with Payload


Ankr proposes to the Balancer community the creation of a ankreth/(steth/Boosted Aave v3) on Arbitrum with the Auto-bribing feature.
ankrETH is a form of ETH Liquid Staking from Ankr Staking that offers instant liquidity for your staked ETH, enabling you to connect your ankrETH tokens with DeFi platforms and earn several more layers of rewards with auto-bribes.
Ankr is a leader in RPC nodes with projects like Aave, 1inch and SushiSwap as clients and has ~$200M TVL across the Liquid Staking Offering.

Protocol Description:

Ethereum Liquid Staking as provided by Ankr Staking offers instant liquidity for your staked ETH, enabling you to connect your ankrETH tokens with DeFi platforms and earn several more layers of rewards.
ankrETH is a reward-bearing token, meaning that the fair value of 1 ankrETH token vs. ETH increases over time as staking rewards accumulate.


The purpose of this proposal is to allow this pool to qualify for BAL incentive distribution in order to deepen the liquidity on Balancer and allow for users to swap ankrETH, the ETH Liquid Staking Asset, for ETH with the help of Auto-bribes on hidden hand.
The intuition behind this is to remedy the capital inefficiency associated with providing liquidity since ankrETH is generating a yield from the Staking Rewards of ETH. As a result, users have an opportunity cost when providing liquidity since the other half of the ETH they provide does not generate any yield.
Therefore, the goal of this proposal is to utilize BAL incentives,Swap Fees and auto-bribes in order to mitigate this capital inefficiency effect.


  1. Governance: ANKR token-holders can propose and vote for changes to the Ankr Staking system. If a change receives enough votes, the Ankr team implement the agreed-upon changes to the platform. Further information may be found here: ANKR Governance Mechanics – Ankr
  2. Oracles: Rate provider for ankrETH and for wstETH.
  3. Audits: Ethereum Liquid Staking smart contracts have undergone an external audit by Beosin Blockchain Security. The full audit report may be found below:
