## **Motivation**

Balancer and LayerZero have successfully deployed contracts that enable veBAL boosts to be bridged across different chains. To enable Aura to bridge it’s veBAL boost cross chain a network remapping manager needs to be set on the `VotingEscrowRemapper` for the Aura VoterProxy.

## Specification

1. 

The DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will initiate a transaction to interact with the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` calling `grantRole` with the following arguments:

role: `0x6bb341db03eede206e544c654a59ef89eea83bc65fada2cfeeaf18c5c0f76ac0`

which corresponds to the role for calling `setNetworkRemappingManager` on the `VotingEscrowRemapper`, verifiable [here](https://github.com/balancer/balancer-deployments/blob/master/action-ids/mainnet/action-ids.json#LL1333C57-L1333C123).

account: `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f`

which corresponds to the DAO Multisig. This allows the multisig to call the above function.

1. 

The DAO multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will interact with VotingEscrowRemapper at `0x83E443EF4f9963C77bd860f94500075556668cb8` (verifiable [here](https://github.com/balancer/balancer-deployments/blob/master/addresses/mainnet.json#L1082)) calling `setNetworkRemappingManager` with the values

localUser: `0xaF52695E1bB01A16D33D7194C28C42b10e0Dbec2` (Aura VoterProxy)  
delegate: `eth:0x5feA4413E3Cc5Cf3A29a49dB41ac0c24850417a0` (Aura DAO multisig)

This grants the ability to call `setNetworkRemapping` to the Aura DAO Multisig, allowing Aura to set their own L2 boost addresses.
