# Smart Contracts

All deployed smart contracts can be found on [GitHub](https://github.com/stakewithus/eth-staking-contracts). Stakewithus will only deploy user funds into smart contracts that have been [audited](/eth-staking/audits.md).

## Staking

The core [Staking](https://github.com/stakewithus/eth-staking-contracts/blob/main/src/Staking.sol) contract of the ETH staking platform which manages all users, fees and deposits. 

### Privileged Roles

#### Operator

The operator is a bot-controlled EOA managed by the Stakewithus team. It listen to user deposits, generates validator signing keys and automatically submits them to the [official Ethereum staking deposit contract](https://ethereum.org/staking/deposit-contract) to create validators.

#### Owner

The owner of the Staking contract is a 2/3 [Safe](https://safe.global/) multisig controlled by Stakewithus team members. It can access all operator functions and also has the authority to set fees for using the platform.

### Functions

## Fee Recipient

The Staking contract deploys individual [Fee Recipient](https://github.com/stakewithus/eth-staking-contracts/blob/main/src/FeeRecipient.sol) contracts for each user upon their first deposit, which serve to collect and distribute their block proposal rewards. Only the user's address can access their rewards - this is set upon creation and cannot be changed.
