CCA Deployment

Deploy Continuous Clearing Auction (CCA) smart contracts using the ContinuousClearingAuctionFactory with CREATE2 for consistent addresses across chains.

> Runtime Compatibility: This skill uses AskUserQuestion for interactive prompts. If AskUserQuestion is not available in your runtime, collect the same parameters through natural language conversation instead.

Instructions for Claude Code

When the user invokes this skill, guide them through the CCA deployment process with appropriate safety warnings and validation.

Pre-Deployment Requirements

Before proceeding with deployment, you MUST:

1. Show educational disclaimer and get user acknowledgment
2. Validate configuration file if provided
3. Verify factory address for the target network
4. Confirm deployment parameters with user

Deployment Workflow

1. Show Educational Disclaimer (REQUIRED)
2. Load or Request Configuration
3. Validate Configuration
4. Display Deployment Plan
5. Get User Confirmation
6. Provide Deployment Commands
7. Post-Deployment Steps

⚠️ Educational Use Disclaimer

IMPORTANT: Before proceeding with deployment, you must acknowledge:

This tool and all deployment instructions are provided for educational purposes only. AI-generated deployment commands may contain errors or security vulnerabilities.

You must:

1. ✅ Review all configurations carefully before deploying
2. ✅ Verify all parameters (addresses, pricing, schedules) are correct
3. ✅ Test on testnets first before deploying to mainnet
4. ✅ Audit your contracts before deploying with real funds

Use AskUserQuestion to confirm the user acknowledges these warnings before proceeding with deployment steps.

Input Validation Rules

Before interpolating ANY user-provided value into forge/cast commands or deployment scripts:

• Ethereum addresses: MUST match ^0x[a-fA-F0-9]{40}$ — reject otherwise
• Chain IDs: MUST be from the supported chains list (1, 130, 143, 1301, 8453, 42161, 11155111)
• Numeric values (supply, prices, blocks, chain IDs): MUST be non-negative and match ^[0-9]+\.?[0-9]*$
• REJECT any input containing shell metacharacters: ;, |, &, $, ` `, (, ), >, standard-json-input.json

Upload this file to block explorers for verification.

## Validation Rules

Before deployment, ensure:

1. **Block constraints**: `startBlock = 0
4. **Floor price alignment**: Floor price must be a multiple of tick spacing
5. **Tick spacing**: At least 1 basis point of floor price (1%, 10% recommended)
6. **Supply schedule**: Last block sells significant tokens (~30%+)
7. **Total supply bounds**: Max 1e30 wei (1 trillion 18-decimal tokens)
8. **No FoT tokens**: Fee-on-transfer tokens not supported
9. **Minimum decimals**: Do not use tokens with = requiredCurrencyRaised`. No bids can exit before graduation.

#### claimTokens()

Users claim purchased tokens after `claimBlock` (only for graduated auctions).

#### sweepCurrency() / sweepUnsoldTokens()

After auction ends:

- `sweepCurrency()`: Withdraw raised currency (graduated only)
- `sweepUnsoldTokens()`: Withdraw unsold tokens

## Supported Chains

CCA is deployed to canonical addresses across select EVM chains:

| Chain ID | Network          | Block Time |
| -------- | ---------------- | ---------- |
| 1        | Mainnet          | 12s        |
| 130      | Unichain         | 1s         |
| 1301     | Unichain Sepolia | 2s         |
| 8453     | Base             | 2s         |
| 42161    | Arbitrum         | 2s         |
| 11155111 | Sepolia          | 12s        |

## Troubleshooting

### Common Issues

| Issue                     | Solution                                            |
| ------------------------- | --------------------------------------------------- |
| "Invalid block sequence"  | Ensure startBlock = 1% of floor price
- [ ] All addresses are valid Ethereum addresses
- [ ] Total supply = 6
- [ ] `onTokensReceived()` called post-deployment
