This tutorial walks you through deploying a contract to BattleChain and getting it ready for stress testing. By the end, you’ll have a contract in attack mode, open for whitehats to test.
Prerequisites: You should have an audited smart contract ready to deploy and some test funds for liquidity.

​
What You’ll Do

  1. Deploy your contract via BattleChainDeployer
  2. Create a Safe Harbor agreement
  3. Request attack mode
  4. Wait for DAO approval

​
Step 1: Deploy Your Contract

The recommended way to deploy is through BattleChainDeployer, which automatically registers your contract with the AttackRegistry. 
// Get the BattleChainDeployer instance
BattleChainDeployer deployer = BattleChainDeployer(BATTLECHAIN_DEPLOYER_ADDRESS);

// Deploy your contract using CREATE2 for deterministic addresses
bytes memory bytecode = type(MyVault).creationCode;
bytes32 salt = keccak256("my-vault-v1");

address myVault = deployer.deployCreate2(salt, bytecode);
// myVault is now registered with AttackRegistry
Your contract is now deployed and registered. You (the deployer) are automatically authorized to request attack mode.
If your contract was deployed through other means, you can still request attack mode using requestUnderAttackByNonAuthorized. This function allows any contract to enter the attack flow, but requires DAO approval like normal.In Step 5, use this instead:
attackRegistry.requestUnderAttackByNonAuthorized(agreement);

​
Step 2: Create a Safe Harbor Agreement

The agreement defines your bounty terms and which contracts are in scope. 
// Prepare contact details
Contact[] memory contacts = new Contact[](1);
contacts[0] = Contact({
    name: "Security Team",
    contact: "[email protected]"
});

// Define which contracts are in scope on BattleChain
Account[] memory accounts = new Account[](1);
accounts[0] = Account({
    accountAddress: "0x1234...your-vault-address",  // Use actual address from Step 1
    childContractScope: ChildContractScope.All
});

Chain[] memory chains = new Chain[](1);
chains[0] = Chain({
    caip2ChainId: "eip155:325",  // BattleChain
    assetRecoveryAddress: "0xYourRecoveryMultisig",
    accounts: accounts
});

// Set bounty terms
BountyTerms memory bountyTerms = BountyTerms({
    bountyPercentage: 10,           // 10% bounty
    bountyCapUsd: 5_000_000,        // $5M max per whitehat
    retainable: true,               // Whitehats keep bounty from recovered funds
    identity: IdentityRequirements.Anonymous,
    diligenceRequirements: "",
    aggregateBountyCapUsd: 0        // No aggregate cap
});

// Create the agreement
AgreementDetails memory details = AgreementDetails({
    protocolName: "My Protocol",
    contactDetails: contacts,
    chains: chains,
    bountyTerms: bountyTerms,
    agreementURI: "ipfs://QmYourAgreementDocument"
});

address agreement = agreementFactory.create(details, msg.sender, salt);

​
Step 3: Extend Commitment Window

The agreement needs a commitment window of at least 7 days: 
// Extend commitment to 30 days from now
IAgreement(agreement).extendCommitmentWindow(block.timestamp + 30 days);

​
Step 4: Adopt the Agreement

Link your protocol to the agreement: 
safeHarborRegistry.adoptSafeHarbor(agreement);

​
Step 5: Request Attack Mode

Now request attack mode for your contracts: 
attackRegistry.requestUnderAttack(agreement);
Your request is submitted! The agreement state is now ATTACK_REQUESTED.

​
Step 6: Wait for DAO Approval

The DAO will review your request. They check:
  • Is this a new contract (not a mainnet copy)?
  • Are the bounty terms reasonable?
  • Is the scope clearly defined?
You can check your status: 
IAttackRegistry.ContractState state = attackRegistry.getAgreementState(agreement);
// ATTACK_REQUESTED (2) = waiting for approval
// UNDER_ATTACK (3) = approved! Whitehats can now attack

​
What’s Next?

Once approved, your contracts are in attack mode:
  • Monitor for attacks: Watch for unusual activity
  • Respond to issues: If a whitehat finds something, they’ll send funds to your recovery address
  • Promote when ready: After sufficient testing, promote to production
