# How to Promote to Production

> Move your contracts from attack mode to production after stress testing

## Overview

After successful stress testing, promote your contracts to production mode. This removes Safe Harbor protection and treats contracts like mainnet deployments.

<Warning>
  Once promoted, there's no going back. Contracts cannot re-enter attack mode.
</Warning>

## Request Promotion

```solidity theme={null}
// Only the attack moderator can promote
attackRegistry.promote(agreementAddress);
```

This starts a 3-day countdown. During this time:

* Contracts are still attackable
* Safe Harbor still applies
* You can cancel if issues are found

## Cancel Promotion

If an issue is discovered during the 3-day wait:

```solidity theme={null}
attackRegistry.cancelPromotion(agreementAddress);
```

This returns the agreement to `UNDER_ATTACK` state.

## Check Promotion Status

```solidity theme={null}
IAttackRegistry.AgreementInfo memory info = attackRegistry.getAgreementInfo(agreementAddress);

if (info.promotionRequestedTimestamp > 0) {
    uint256 promotionTime = info.promotionRequestedTimestamp + 3 days;

    if (block.timestamp >= promotionTime) {
        // Now in PRODUCTION
    } else {
        // Still in PROMOTION_REQUESTED, can cancel
    }
}
```

## Mark as Corrupted

If a whitehat successfully exploits your contracts:

```solidity theme={null}
attackRegistry.markCorrupted(agreementAddress);
```

This sets state to `CORRUPTED` (terminal), signaling the contracts are compromised.

## Transfer Attack Moderator

The attack moderator controls promotion. To transfer:

```solidity theme={null}
attackRegistry.transferAttackModerator(agreementAddress, newModerator);
```

## After Promotion

1. **Deploy to mainnet**: Your contracts are battle-tested
2. **Keep monitoring**: Continue to watch your BattleChain deployment
3. **Mirror updates**: Keep BattleChain and mainnet in sync
4. **Use for staging**: Future updates can use BattleChain's attack mode
