Protocol Description:

Frax is a stable coin issued by Frax and sfrxETH is a Frax’s staked wrapped ETH token


As a joint effort with FRAX and Beethoven X, we aim to increase liquidity of FRAX, sFRAX, frxETH, sfrxETH, to make Balancer a liquidity hub for frax assets on optimism. The BAL gauge will facilitate the process.


  1. Governance: FRAX governance process can be seen here and their snapshot here.
  2. Oracles: Rate provider contract for sfrxETH, the pool does not rely on additional oracles.
  3. Audits: See here
  4. Centralization vectors: see here.
  5. Market History: See FRAX and sfrxETH
  6. Value: Balancer will earn the protocol fee on interest bearing sfrxETH in the pool and so will LPs. The BIP-19 flywheel will incentivize TVL to grow here with trading volume and our staked ethereum pillars will continue to have Balancer as their ideal liquidity destination.

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

Additionally, this pool is requesting core pool status as per BIP-457
