# Smart Contract Governance

## Contract Administration

Solv protocol's smart contract upgrade mechanism utilizes OpenZeppelin's upgradeable contract framework. This framework allows for secure and seamless contract upgrades, ensuring that new functionality can be added without disrupting existing contract states. For more information, please refer to the official documentation: [Upgradeable Contracts Documentation](https://docs.openzeppelin.com/contracts/5.x/upgradeable).

The admin privileges for upgrades are assigned to a Gnosis Safe multi-signature address, providing a secure and decentralized way to manage contract upgrades. The timelock mechanism will be added to further enhance security by introducing a delay between the upgrade proposal and execution.

### Contract Administrators

<table><thead><tr><th width="246">Contract</th><th>Contract Administrator Address</th></tr></thead><tbody><tr><td>SolvBTCFactory<br>SolvBTCYieldTokenFactory<br>MultiAssetPool<br>Router<br>Oracle</td><td>0x0c2Bc4d2698820e12E6eBe863E7b9E2650CD5b7D</td></tr></tbody></table>

Note:&#x20;

1. The contract upgrade Administrator address is unified across all chains.
2. For the relationship of these contracts, please refer to the [smart contract documentation](https://docs.solv.finance/technical-documentation/smart-contracts).

## Runtime Configuration

### Access Control Model

Solv Protocol's smart contract runtime configuration uses OpenZeppelin's access control model, as described in [Access Control Documentation](https://docs.openzeppelin.com/contracts/5.x/access-control).

#### Parameter Configuration

The permission model for updating business parameters (such as adding supported tokens, setting Oracle address, etc.) uses OpenZeppelin’s **Ownable** implementation, with the permission address being a Gnosis Safe multi-signature address.&#x20;

#### Token Mint/Burn

Role-based access control mechanism for permission management is used for cross chain Mint/Burn for SolvBTC and related LSTs, which allows for flexible management and assignment of various contract permissions. By assigning specific roles to different entities, we ensure the security and control of contract operations.&#x20;
