[BIP478] Enable 80mevETH/20FOLD Gauge [Ethereum]

PR with Payload


This is a proposal to enable a Balancer gauge for mevETH/FOLD Weighted pool on Balancer Ethereum.

The objective of this proposal is to enable this pool to be eligible for BAL incentive distribution, thereby enhancing liquidity on Balancer. This will facilitate users in swapping mevETH, an Liquid Staking Asset, and FOLD, Manifold’s governance token. The pool includes a rate provider for mevETH and therefore requests to be made a core pool.

Protocol Description:

The MEV Protocol is a collaborative innovation designed to revolutionize Ethereum’s network security and decentralization. It is forged by the pioneers of the first ETH staking service and notable figures in Ethereum infrastructure. The protocol introduces mevETH, a Liquid Staking Token (LST), aimed at optimizing value for validators.

The MEV Protocol’s approach harnesses relayers, block proposers, and block builders to enhance the MEV supply chain. Reward avenues encompass the validator base fee, LP incentives, and the multiple auction winners previously discussed. Additional reward developments are on the horizon…

Transparency and fairness in block validation are offered through a variety of options, allowing validators to decide who receives the rights to their blocks. The protocol recognizes that such crucial decisions should not be monopolized by a single organization in private.

mevETH has over 28,000 ETH staked in it and has been receiving rewards since mid-August.

FOLD is the governance token for Manifold Finance, which jurisdicts which Operators will be able to make decisions on behalf of the DAO. More can be outlined here.


The pool is an 80/20 Weighted Pool, which will host majority mevETH tokens as a yield bearing source for LPs as well as manifold’s governance token FOLD.


  1. Governance: 5/8 multisig address: 0x617c8dE5BdE54ffbb8d92716CC947858cA38f582. It has the power to upgrade the contracts & modules.
  2. Oracles: N/A
  3. Audits:
  1. Centralization vectors: No. Same as describe in the governance.
  2. Market History:
  1. Value: The pool is intended to be the one of the primary sources of liquidity

The rate provider used for mevETH was reviewed by the integrations team and full report can be seen here . The summary judgement deemed the rate provider safe enough for the use case, with minimal risk related to it.


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): Ethereum

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