## Background
Contracts are deployed, and everything is looking good for Balancers launch on Base Chain. This BIP includes a number of final steps that must be taken to get everything working.
Along with the typical wireup of permissions, the Gauge Factory and Authorizer Wrapper are also being configured, and a 50% protocol fee is being set.
## English Specification
The transaction details for `base.json` were generated by [this script](https://github.com/BalancerMaxis/multisig-ops/blob/main/action-scripts/gen_add_permissions_payload.py) with inputs and outputs in [this directory](https://github.com/BalancerMaxis/multisig-ops/tree/staging/BIPs/BIP-388)
The following files can be found both linked below and in the payload PR linked above:
| Filename | Description of Contents |
| --- | --- |
| [inputs.json](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/inputs.json) | The inputs to the script mapping functions and deployments to target addresses that can execute them. |
| [results\_address\_sorted.md](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/results_address_sorted.md) | The resulting changes printed in a table sorted by target chain and target address. (to easily understand permisisons granted) |
| [results\_deployment\_sorted.md](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/results_deployment_sorted.md) | The resulting changes printed in a table sorted by target chain and target deployment. (for verification against action ids) |
| [function\_descriptions.md](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/function_descriptions.md) | A table that describes what each function that is being granted privileged access to allows. |
| [base.json](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/base.json) | Permissions Changes on base described by the outputs above |
| [BIP-388A.json](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/BIP-388A.json) | Sets 50% Protocol Fees on Base Chain as per current standards |
| [BIP-388B.json](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/BIP-388B.json) | Wires up the Gauge Factory to allow Gauges receive bal. |
| [BIP-388C.json](https://github.com/BalancerMaxis/multisig-ops/blob/staging/BIPs/2023-W30/BIP-388/BIP-388C.json) | Enables the Authroizer Wrapper - see [BIP-277](https://forum.balancer.fi/t/bip-277-enable-authorizer-wrapper/4718) |

# Specification
- `base.json` applies the standard permissions described in the tables above.
- `BIP-388A.json` sets protocol fees to 50% for swaps and yields (types 0 and 2)
- `BIP-388B.json` Wires the Gauge Factory up to the Psuedominter, adding and removing permisisons to do so in the process.
- `BIP-388C.json` Enables the authorizer wrapper, adding and removing permissions to do so in the process.
## Risk Assessment
This is all part of the standard process for provisioning a new chain. There are currently no deposits on base chain, this presents to risk to current protocol operations.
