## Motivation For a refresher on what the Batch Relayer is you can review the proposal to [approve the Batch Relayer](https://forum.balancer.fi/t/proposal-authorize-the-batch-relayer/2378) and to [approve the Batch Relayer v2](https://forum.balancer.fi/t/proposal-polygon-authorize-batch-relayer-v2-for-usd-boosted-pool/2655) and to approve [Batch Relayer v3](https://forum.balancer.fi/t/bip-31-authorize-the-batch-relayer-v3/3488). The functionality added in v4 includes some quality of life improvements and adds the ability to wrap & unwrap [Reaper](https://www.reaper.farm/) linear pool tokens. This enables us to launch Reaper boosted pools on Optimism. We can’t plug directly into Aave v3 until Aave releases compatible atoken wrappers - by using a Reaper single strategy non-upgradable vault that only farms Aave we can get around this problem while introducing only a minimal amount of additional risk. Reaper’s single strategy vault architecture was forked from Yearn and has been live for months with 9 figures of TVL at the peak so it can be considered relatively battle tested. ## Specification ### Ethereum If approved, the DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will initiate a transaction to the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` calling `grantRoles` with the following arguments: roles: `0x1282ab709b2b70070f829c46bc36f76b32ad4989fecb2fcb09a1b3ce00bbfc30` for `batchSwap` `0xc149e88b59429ded7f601ab52ecd62331cac006ae07c16543439ed138dcb8d341` for `exitPool` `0x78ad1b68d148c070372f8643c4648efbb63c6a8a338f3c24714868e791367653` for `joinPool` `0xeba777d811cd36c06d540d7ff2ed18ed042fd67bbf7c9afcf88c818c7ee6b498` for `manageUserBalance` `0x0014a06d322ff07fcc02b12f93eb77bb76e28cdee4fc0670b9dec98d24bbfec8` for `setRelayerApproval` `0x7b8a1d293670124924a0f532213753b89db10bde737249d4540e9a03657d1aff` for `swap` These may all be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/action-ids/mainnet/action-ids.json#L16). account: `0x2536dfeeCB7A0397CF98eDaDA8486254533b1aFA` This can be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/tasks/20220916-batch-relayer-v4/output/mainnet.json). ### Polygon If approved, the DAO Multisig `0xd2bD536ADB0198f74D5f4f2Bd4Fe68Bae1e1Ba80` will initiate a transaction to the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` calling `grantRoles` with the following arguments: roles: `0x1282ab709b2b70070f829c46bc36f76b32ad4989fecb2fcb09a1b3ce00bbfc30` for `batchSwap` `0xc149e88b59429ded7f601ab52ecd62331cac006ae07c16543439ed138dcb8d341` for `exitPool` `0x78ad1b68d148c070372f8643c4648efbb63c6a8a338f3c24714868e791367653` for `joinPool` `0xeba777d811cd36c06d540d7ff2ed18ed042fd67bbf7c9afcf88c818c7ee6b498` for `manageUserBalance` `0x0014a06d322ff07fcc02b12f93eb77bb76e28cdee4fc0670b9dec98d24bbfec8` for `setRelayerApproval` `0x7b8a1d293670124924a0f532213753b89db10bde737249d4540e9a03657d1aff` for `swap` These may all be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/action-ids/polygon/action-ids.json#L16). account: `0x28A224d9d398a1eBB7BA69BCA515898966Bb1B6b` This can be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/tasks/20220916-batch-relayer-v4/output/polygon.json). ### Arbitrum If approved, the DAO Multisig `0x6207ed574152496c9B072C24FD87cE9cd9E17320` will initiate a transaction to the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` calling `grantRoles` with the following arguments: roles: `0x1282ab709b2b70070f829c46bc36f76b32ad4989fecb2fcb09a1b3ce00bbfc30` for `batchSwap` `0xc149e88b59429ded7f601ab52ecd62331cac006ae07c16543439ed138dcb8d341` for `exitPool` `0x78ad1b68d148c070372f8643c4648efbb63c6a8a338f3c24714868e791367653` for `joinPool` `0xeba777d811cd36c06d540d7ff2ed18ed042fd67bbf7c9afcf88c818c7ee6b498` for `manageUserBalance` `0x0014a06d322ff07fcc02b12f93eb77bb76e28cdee4fc0670b9dec98d24bbfec8` for `setRelayerApproval` `0x7b8a1d293670124924a0f532213753b89db10bde737249d4540e9a03657d1aff` for `swap` These may all be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/action-ids/arbitrum/action-ids.json#L16). account: `0x5bf3B7c14b10f16939d63Bd679264A1Aa951B4D5` This can be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/tasks/20220916-batch-relayer-v4/output/arbitrum.json). ### Optimism If approved, the DAO Multisig `0x043f9687842771b3dF8852c1E9801DCAeED3f6bc` will initiate a transaction to the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` calling `grantRoles` with the following arguments: roles: `0x1282ab709b2b70070f829c46bc36f76b32ad4989fecb2fcb09a1b3ce00bbfc30` for `batchSwap` `0xc149e88b59429ded7f601ab52ecd62331cac006ae07c16543439ed138dcb8d341` for `exitPool` `0x78ad1b68d148c070372f8643c4648efbb63c6a8a338f3c24714868e791367653` for `joinPool` `0xeba777d811cd36c06d540d7ff2ed18ed042fd67bbf7c9afcf88c818c7ee6b498` for `manageUserBalance` `0x0014a06d322ff07fcc02b12f93eb77bb76e28cdee4fc0670b9dec98d24bbfec8` for `setRelayerApproval` `0x7b8a1d293670124924a0f532213753b89db10bde737249d4540e9a03657d1aff` for `swap` These may all be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/action-ids/optimism/action-ids.json#L16). account: `0x1a58897Ab366082028ced3740900ecBD765Af738` This can be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/tasks/20220916-batch-relayer-v4/output/optimism.json). ---
