# Contracts

# Introduction

The [mev-commit contracts](https://github.com/primev/mev-commit/tree/main/contracts) verify and manage the movement of funds as a response to bid and commitment activities that occur on our p2p network.

For mev-commit testnet contract addresses please refer to [Testnet](/v0.6.3/developers/testnet) section.

## Core Contracts

The mev-commit protocol has 5 **core contracts**, which are all deployed on the mev-commit chain:

* **Preconf Manager**
  * This will persist details about the commitments that have been made into contract storage.
* **Bidder Registry**
  * This will be where the bulk of monetary transfer occurs.
  * Bidders deposit for bids into this contract.
  * The payment gets processed into a provider-allocated section that a provider can later retrieve.
* **Provider Registry**
  * This contract stores the stake a provider bounds to ensure it doesn't break its promises under preconfirmations.
* **Oracle**
  * This simply retrieves details on which commitments to process for rewarding or slashing.
  * Access to the functions on this contract is restricted to the owner of the Oracle key.
* **Block Tracker**
  * This will track Ethereum blocks and their winners, so commitments could be rewarded or slashed
  * Access to the functions on this contract is restricted to the owner of the Oracle key.

## Validator Registry Contracts

The validator registry contracts are deployed on L1, and enable three methods of validator opt-in:

* **Validator Opt-In Router**
  * ValidatorOptInRouter enables actors to query whether a validator is opted-in to the mev-commit protocol from any of the below three methods.
* **Vanilla Registry**
  * VanillaRegistry allows validators to opt-in to mev-commit by staking native ETH directly with the contract.
  * This stake is separate from a validator's 32 ETH already staked with the beacon chain.
* **Mev-commit AVS**
  * MevCommitAVS acts as a tie-in to Eigenlayer core contracts, enabling validators to opt-in to the mev-commit protocol via native restaking.
* **Mev-commit middleware**
  * MevCommitMiddleware serves as tie-in to Symbiotic core contracts, enabling validators to opt-in to the mev-commit protocol via restaking ERC20 tokens with vaults.

## Deploying Custom Contracts

you can deploy any EVM compatible contracts to the mev-commit chain, simply set your **Chain ID to 17864** and RPC Url to `https://chainrpc.testnet.mev-commit.xyz`.
