LDO - Reward Controller Access Request

Simple Summary

This proposal is to enable Lido to distribute LDO rewards across the Aave v3 Ethereum, Arbitrum and Optimism Liquidity Pools. The Emission_Admin role for LDO on each network is to be assigned to a wallet controlled by the Lido DAO.

Abstract

Lido seeks to distribute LDO rewards across to the various Aave v3 deployments. To achieve this, the EmissionManager function assigns an owner to the Emission_Admin role for LDO on each respective Aave v3 deployment, [1,2].

The wallet with Emission Admin permission for LDO on each aave v3 deployment then controls the distribution of only LDO rewards across the respective Liquidity Pool.

Motivation

Enable Lido DAO to distribute LDO rewards across the Ethereum, Arbitrum and Optimism v3 Liquidity Pools.

The Lido Liquidity Mining Committee (LMC) determines the emission rate and duration at which LDO rewards are offered.

Typically, the LMC meets and determines the next 30 days of LDO rewards on a rolling basis. This means each month, the committee will determine if to extend the LDO rewards, or change the amount of LDO being offered across the various Aave v3 Liquidity Pools.

Specification

The EmissionManager, a governance controlled contract, assigns the Emission_Admin role for a specified token, LDO on each respective network.

The Emission_Admin role controls the distribution of the specified token, LDO, across the specified Aave deployment.

The Emission_Admin can distribute LDO anywhere across the Aave v3 Ethereum, Arbitrum and Optimism Liquidity Pool.

Implementation

Set Emission_Admin permission for LDO to the following Lido address:
