# CCA Configuration

Configure Continuous Clearing Auction (CCA) smart contract parameters for fair and transparent token distribution.

> **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 a **bulk interactive form configuration flow** using AskUserQuestion. Collect parameters in batches to minimize user interaction rounds.

### Bulk Interactive Form Rules

1. **Batch questions** - Ask up to 4 questions at once using a single AskUserQuestion call
2. **Allow direct input** - For fields requiring custom values (addresses, numbers):
   - Provide a "Not available yet" or "Skip for now" option
   - The "Other" option (automatically provided) allows direct custom input
   - **NEVER** ask "Do you have X?" as a separate question
3. **Store answers** - Keep track of all collected values in a configuration object
4. **Validate after collection** - After each batch, validate all inputs before proceeding
5. **Show progress** - After each batch, show which parameters are collected and which remain

### Configuration Flow

Collect parameters in these batches:

#### Batch 1: Task Selection (1 question)

**Question 1: Task Type**

- Prompt: "What would you like to do with CCA?"
- Options: "Configure auction parameters", "Generate supply schedule only", "Review existing config", "Deploy existing config"

**After collection:** If not "Configure auction parameters", skip to appropriate section.

---

#### Batch 2: Basic Configuration (4 questions)

**Question 1: Network**

- Prompt: "Which network to deploy on?"
- Options: "Ethereum Mainnet", "Unichain (Mainnet)", "Unichain Sepolia (Testnet)", "Base", "Arbitrum", "Sepolia"
- Store: `chainId`, `blockTime`, `rpcUrl`, `currencyDecimals` (for selected currency)

**Question 2: Token Address**

- Prompt: "Token to be auctioned?"
- Options: "Token not deployed yet" (placeholder), Custom address (via "Other")
- Validation: Must be 42 chars starting with 0x
- Store: `token`

**Question 3: Total Supply**

- Prompt: "How many tokens to auction?"
- Options: "100 million tokens (18 decimals)", "1 billion tokens (18 decimals)", "10 billion tokens (18 decimals)", Custom (via "Other")
- Validation: Must be <= 1e30 wei
- Store: `totalSupply`

**Question 4: Currency**

- Prompt: "What currency should bidders use?"
- Options: "ETH (Native)", "USDC on [network]", "USDT on [network]", Custom ERC20 (via "Other")
- Validation: Must be 42 chars starting with 0x or address(0)
- Store: `currency`

**After collection:** Validate all inputs, show summary of basic configuration.

---

#### Batch 3: Timing & Pricing (4 questions)

**Question 1: Auction Duration**

- Prompt: "How long should the auction run?"
- Options: "1 day", "2 days", "3 days", "7 days", Custom blocks (via "Other")
- Calculate blocks based on network block time
- Store: `auctionBlocks`

**Question 2: Prebid Period**

- Prompt: "Include a prebid period? (time when no tokens are sold)"
- Options: "No prebid period (0 blocks)", "12 hours", "1 day", Custom blocks (via "Other")
- Calculate blocks based on network block time
- Store: `prebidBlocks`

**Question 3: Floor Price**

- Prompt: "Starting floor price? (ratio of currency per token)"
- Options: "0.10x (10% of 1:1 ratio)", "0.01x (1% of 1:1 ratio)", "0.001x (0.1% of 1:1 ratio)", Custom ratio (via "Other")
- Calculate Q96 value accounting for decimal differences: `Q96 * ratio / 10^(tokenDecimals - currencyDecimals)`
- For USDC (6 decimals) and 18-decimal token: `Q96 * ratio / 10^12`
- For native ETH (18 decimals) and 18-decimal token: `Q96 * ratio / 10^0 = Q96 * ratio`
- Store: `floorPriceRatio`, `floorPrice` (Q96), `tokenDecimals`, `currencyDecimals`

**Question 4: Tick Spacing**

- Prompt: "Tick spacing as percentage of floor price?"
- Options: "1% of floor price (Recommended)", "10% of floor price", "0.1% of floor price", Custom percentage (via "Other")
- Calculate: `tickSpacing = int(floorPrice * percentage)`
- **CRITICAL**: Round floor price DOWN to be evenly divisible by tick spacing:
  - `roundedFloorPrice = (floorPrice // tickSpacing) * tickSpacing`
  - Verify: `roundedFloorPrice % tickSpacing == 0` must be true
- Validate: Tick spacing must be >= 1 basis point of floor price
- Store: `tickSpacingPercentage`, `tickSpacing` (Q96), `roundedFloorPrice`

**After collection:** Validate inputs, verify floor price divisibility, calculate and display Q96 values, show timing summary.

---

#### Batch 4: Recipients & Launch (4 questions)

**Question 1: Tokens Recipient**

- Prompt: "Where should unsold tokens be sent?"
- Options: "Same as funds recipient", Custom address (via "Other")
- Validation: Must be 42 chars starting with 0x
- Store: `tokensRecipient`

**Question 2: Funds Recipient**

- Prompt: "Where should raised funds be sent?"
- Options: "Same as tokens recipient", Custom address (via "Other")
- Validation: Must be 42 chars starting with 0x
- Store: `fundsRecipient`

**Question 3: Start Time**

- Prompt: "When should the auction start?"
- Options: "In 1 hour", "In 6 hours", "In 24 hours", Custom block number (via "Other")
- Fetch current block number from RPC and calculate
- Store: `startBlock`
- Calculate: `endBlock = startBlock + prebidBlocks + auctionBlocks`, `claimBlock = endBlock`

**Question 4: Minimum Funds Required**

- Prompt: "Require minimum currency raised for graduation?"
- Options: "No minimum (0)", "100 ETH", "1000 ETH", Custom amount in wei (via "Other")
- Store: `requiredCurrencyRaised`

**After collection:** Validate addresses, fetch current block from RPC, calculate full block timeline.

---

#### Batch 5: Optional Hook (1 question)

**Question 1: Validation Hook**

- Prompt: "Use a validation hook contract?"
- Options: "No validation hook", Custom hook address (via "Other")
- Validation: Must be 42 chars starting with 0x (if provided)
- Store: `validationHook`

**After collection:** Validate hook address if provided.

---

#### Step 6: Generate Supply Schedule

**If MCP server is not running**, provide instructions to start it:

```bash
# Navigate to MCP server directory
cd packages/plugins/uniswap-cca/mcp-server/supply-schedule

# Run setup script (first time only)
chmod +x setup.sh
./setup.sh

# Start the MCP server
python3 server.py
```

Once the MCP server is running, call the `cca-supply-schedule__generate_supply_schedule` MCP tool with the collected parameters. The tool expects a JSON object:

```json
{
  "auction_blocks": 86400,
  "prebid_blocks": 0
}
```

Replace the values with the actual `auctionBlocks` and `prebidBlocks` collected from the user.

If the MCP tool is unavailable, use the fallback Python algorithm directly (see Supply Schedule Configuration section).

Store: `supplySchedule`

#### Step 7: Generate and Display Configuration

After collecting all parameters and generating the supply schedule, display the complete JSON configuration in the CLI output:

```json
{
  "[chainId]": {
    "token": "...",
    "totalSupply": ...,
    "currency": "...",
    "tokensRecipient": "...",
    "fundsRecipient": "...",
    "startBlock": ...,
    "endBlock": ...,
    "claimBlock": ...,
    "tickSpacing": ...,
    "validationHook": "...",
    "floorPrice": ...,
    "requiredCurrencyRaised": ...,
    "supplySchedule": [...]
  }
}
```

**Do NOT automatically create a file.** Let the user copy the JSON or specify a filepath to save it.

#### Step 8: Display Summary

Show the user a comprehensive formatted summary including:

- Network and chain ID
- Token and currency details
- Block timeline (start, end, claim) with human-readable times
- Pricing (floor price, tick spacing) in both Q96 and ratio formats
- Recipients (tokens, funds)
- Supply schedule summary (total phases, final block percentage)
- Validation checklist (all validation rules passed/failed)

#### Step 9: Next Steps

Ask the user what they want to do:

- "Save to file" (ask for filepath, default: `script/auction-config.json`)
- "View deployment instructions" (suggest using the deployer skill)
- "Modify configuration"
- "Exit" (just end, they can copy the JSON from CLI output)

### Important Notes

- **Validate in batches** - Validate all inputs after each batch collection
- **Fetch current block number** from RPC when calculating start/end blocks
- **Calculate Q96 values** correctly for floor price and tick spacing:
  - **CRITICAL**: Account for decimal differences: `Q96 * ratio / 10^(tokenDecimals - currencyDecimals)`
  - USDC is 6 decimals on all networks - divide by 10^12 for 18-decimal tokens
  - Native ETH is 18 decimals - no adjustment needed for 18-decimal tokens
- **Round floor price** to be evenly divisible by tick spacing:
  - `roundedFloorPrice = (floorPrice // tickSpacing) * tickSpacing`
  - **MUST verify**: `roundedFloorPrice % tickSpacing == 0`
- **Use the MCP tool** for supply schedule generation (provide setup instructions if not running)
- **Minimize interaction rounds** - Collect as many params as reasonable per batch

### Network-Specific Constants

Store these for quick reference:

```typescript
const NETWORKS = {
  1: {
    name: 'Mainnet',
    blockTime: 12,
    rpc: 'https://ethereum-rpc.publicnode.com',

};

// Q96 = 2^96 (JavaScript BigInt notation)
const Q96 = 79228162514264337593543950336n;

Python equivalent:

```python
# Q96 = 2**96
Q96 = 79228162514264337593543950336
```

## Overview

CCA (Continuous Clearing Auction) is a novel auction mechanism that generalizes the uniform-price auction into continuous time. It provides fair price discovery for bootstrapping initial liquidity while eliminating timing games and encouraging early participation.

Key features:

- **Fair price discovery**: Continuous clearing with no timing games
- **Transparent distribution**: Supply released on a predetermined schedule
- **Flexible configuration**: Customizable auction parameters and schedules
- **Multi-chain support**: Canonical deployment across EVM chains
- **Factory deployment**: Consistent addresses via CREATE2

## Configuration Guide

### Auction Parameters

CCA auctions are configured through the `AuctionParameters` struct:

```solidity
struct AuctionParameters {
    address currency;              // Token to raise funds in (address(0) for ETH)
    address tokensRecipient;       // Address to receive leftover tokens
    address fundsRecipient;        // Address to receive all raised funds
    uint64 startBlock;             // Block when auction starts
    uint64 endBlock;               // Block when auction ends
    uint64 claimBlock;             // Block when tokens can be claimed
    uint256 tickSpacing;           // Fixed granularity for prices (Q96)
    address validationHook;        // Optional hook (use 0x0 if none)
    uint256 floorPrice;            // Starting floor price (Q96)
    uint128 requiredCurrencyRaised; // Minimum funds to graduate
    bytes auctionStepsData;        // Packed supply issuance schedule
}
```

### Configuration File Format

    ]
  }
}
```

## Price Calculations (Q96 Format)

CCA uses Q96 fixed-point format for precise pricing. The base value `2^96` (79228162514264337593543950336) represents a 1:1 price ratio.

### Floor Price Calculation

**CRITICAL: Account for decimal differences between token and currency.**

```python
# Base value for 1:1 ratio
Q96 = 79228162514264337593543950336

# Formula: Q96 * (human price ratio) / 10^(token_decimals - currency_decimals)

# Example 1: USDC (6 decimals) per 18-decimal token at $0.10 ratio
token_decimals = 18
currency_decimals = 6  # USDC has 6 decimals
decimal_adjustment = 10 ** (token_decimals - currency_decimals)  # 10^12

floorPrice = Q96 * 0.1 / decimal_adjustment
# Result: 7922816251426433759354395 (approximately)

# Example 2: Native ETH (18 decimals) per 18-decimal token at 0.1 ratio
token_decimals = 18
currency_decimals = 18  # Native ETH has 18 decimals
decimal_adjustment = 10 ** (18 - 18)  # 10^0 = 1

floorPrice = Q96 * 0.1 / 1
# Result: 7922816251426433759354395034
```

**Key Point:** USDC has 6 decimals on all networks, so you must divide by 10^12 when using USDC with 18-decimal tokens.

### Tick Spacing Calculation

Tick spacing governs where bids can be placed. Choose **AT LEAST 1 basis point of the floor price**. 1% or 10% is also reasonable.

```python
# Example: 1% of floor price
tickSpacing = int(floorPrice * 0.01)

# For floorPrice = 7922816251426433759354395000
# Result: 79228162514264337593543950
```

### Rounding Floor Price (CRITICAL)

**Floor price MUST be evenly divisible by tick spacing.** Round DOWN to ensure exact divisibility:

```python
# Calculate tick spacing first
tickSpacing = int(floorPrice * 0.01)  # 1% of floor price

# Round floor price DOWN to be evenly divisible
roundedFloorPrice = (floorPrice // tickSpacing) * tickSpacing

# VERIFY divisibility (must be True)
assert roundedFloorPrice % tickSpacing == 0, "Floor price must be divisible by tick spacing!"
```

**Example:**

```python
Q96 = 79228162514264337593543950336
raw_floor_price = int(Q96 * 0.0001)  # 0.0001 ETH per token
# Result: 7922816251426434139029504

tick_spacing = int(raw_floor_price * 0.01)  # 1%
# Result: 79228162514264350785536

rounded_floor_price = (raw_floor_price // tick_spacing) * tick_spacing
# Result: 7843588088912170727768064

# Verify: 7843588088912170727768064 / 79228162514264350785536 = 99 (exact)
# Remainder: 0 ✓
```

**Warning**: Setting too small of a tick spacing will make the auction extremely gas inefficient and can result in DoS attacks.

## Supply Schedule Configuration

### Understanding MPS (Milli-Basis Points)

Supply schedules use **MPS = 1e7** (10 million), where each unit represents one thousandth of a basis point.

The supply schedule defines the token issuance rate over time. Each step contains:

- `mps`: Tokens released per block (in mps units)
- `blockDelta`: Number of blocks this rate applies

### Standard Schedule Generator

The plugin includes an MCP server that generates supply schedules using a **normalized convex curve** with the following properties:

- **12 steps** (default, configurable) for gradual release
- **Equal token amounts** per step (5.8333% for 70% gradual release)
- **Decreasing block durations** (convex curve property)
- **Large final block** receives remaining tokens (~30%, configurable 20-40%)
- **Total**: Always exactly 10,000,000 MPS

Use the MCP tool `generate_supply_schedule` to generate this standard distribution:

**MCP Tool Call:**

```json
{
  "auction_blocks": 86400,
  "prebid_blocks": 0
}
```

The algorithm automatically calculates:

1. Equal token amounts per step (e.g., 5.8333% for 12 steps with 70% gradual)
2. Time boundaries from normalized curve C(t) = t^α (default α = 1.2)
3. Block durations that DECREASE over time (convex curve property)
4. Final block adjustment to hit exactly 10,000,000 MPS total

### Example: 2-day auction on Base

Base uses 2s blocks, so 2 days = 86400 blocks.

Call `generate_supply_schedule` with:

```json
{
  "auction_blocks": 86400,
  "prebid_blocks": 0
}
```

**Output (normalized convex distribution):**

```json
{
  "schedule": [
    { "mps": 54, "blockDelta": 10894 },
    { "mps": 68, "blockDelta": 8517 },
    { "mps": 75, "blockDelta": 7803 },
    { "mps": 79, "blockDelta": 7373 },
    { "mps": 83, "blockDelta": 7068 },
    { "mps": 85, "blockDelta": 6835 },
    { "mps": 88, "blockDelta": 6647 },
    { "mps": 90, "blockDelta": 6490 },
    { "mps": 92, "blockDelta": 6356 },
    { "mps": 94, "blockDelta": 6238 },
    { "mps": 95, "blockDelta": 6136 },
    { "mps": 97, "blockDelta": 6043 },
    { "mps": 2988006, "blockDelta": 1 }
  ],
  "auction_blocks": 86400,
  "prebid_blocks": 0,
  "total_phases": 13,
  "summary": {
    "total_mps": 10000000,
    "target_mps": 10000000,
    "final_block_mps": 2988006,
    "final_block_percentage": 29.88,
    "num_steps": 12,
    "alpha": 1.2,
    "main_supply_pct": 70.0,
    "step_tokens_pct": 5.8333
  }
}
```

**Notice:**

- Block durations DECREASE: 10894 → 8517 → 7803 → ... → 6043
- Token amounts per step are approximately equal (~5.8333% each)
- Final block contains 29.88% of all tokens
- Total is exactly 10,000,000 MPS

### Example: With prebid period

Add a prebid period where no tokens are released (mps=0). The prebid is prepended to the schedule.

Call `generate_supply_schedule` with:

```json
{
  "auction_blocks": 86400,
  "prebid_blocks": 43200
}
```

**Output:**

```json
{
  "schedule": [
    { "mps": 0, "blockDelta": 43200 },
    { "mps": 54, "blockDelta": 10894 },
    { "mps": 68, "blockDelta": 8517 },
    ...
    { "mps": 2988006, "blockDelta": 1 }
  ],
  "auction_blocks": 86400,
  "prebid_blocks": 43200,
  "total_phases": 14,
  "summary": {
    "total_mps": 10000000,
    "target_mps": 10000000,
    "final_block_mps": 2988006,
    "final_block_percentage": 29.88,
    "num_steps": 12,
    "alpha": 1.2,
    "main_supply_pct": 70.0,
    "step_tokens_pct": 5.8333
  }
}
```

**Notice:** The prebid phase is simply prepended with `mps: 0`. The auction portion still uses the same normalized convex distribution.

### Custom Schedule

For custom distribution, manually define the schedule:

```json
{
  "supplySchedule": [
    { "mps": 100, "blockDelta": 5000 },
    { "mps": 200, "blockDelta": 5000 },
    { "mps": 500, "blockDelta": 4400 }
  ]
}
```

**Important**: The last block should sell a significant amount of tokens (typically 30%+) to prevent price manipulation.

## Encoding Supply Schedule for Onchain Deployment

After generating a supply schedule, it must be encoded into a bytes format for the onchain `AuctionParameters` struct. The encoding packs each `{mps, blockDelta}` element into a uint64.

### Encoding Algorithm

For each element in the supply schedule:

1. **Create uint64** (64 bits / 8 bytes) where:
   - First 24 bits: `mps` value (left padded)
   - Next 40 bits: `blockDelta` value (left padded)
2. **Pack all uint64s** together via `encodePacked` (concatenate bytes)
3. **Return** as hex bytes string with `0x` prefix

### Encoding Formula

```solidity
// Solidity equivalent
uint64 packed = (uint64(mps) << 40) | uint64(blockDelta);
bytes memory auctionStepsData = abi.encodePacked(packed1, packed2, ...);
```

### Value Constraints

- **mps**: Must fit in 24 bits (max: 16,777,215)
- **blockDelta**: Must fit in 40 bits (max: 1,099,511,627,775)

### Using the MCP Tool

Use the `encode_supply_schedule` MCP tool to encode a supply schedule:

**Input:**

```json
{
  "schedule": [
    { "mps": 0, "blockDelta": 43200 },
    { "mps": 54, "blockDelta": 10894 },
    { "mps": 68, "blockDelta": 8517 }
  ]
}
```

**Output:**

```json
{
  "encoded": "0x0000000000a8c00000003600002aa60000004400002145...",
  "length_bytes": 112,
  "num_elements": 14
}
```

### Manual Encoding Example (Python)

```python
def encode_supply_schedule(schedule):
    """Encode supply schedule to bytes."""
    encoded_bytes = b''

    for item in schedule:
        mps = item['mps']
        block_delta = item['blockDelta']

        # Validate bounds
        assert mps < 2**24, f"mps {mps} exceeds 24-bit max"
        assert block_delta < 2**40, f"blockDelta {block_delta} exceeds 40-bit max"

        # Pack into uint64: mps (24 bits) << 40 | blockDelta (40 bits)
        packed = (mps << 40) | block_delta

        # Convert to 8 bytes (big-endian)
        encoded_bytes += packed.to_bytes(8, byteorder='big')

    return '0x' + encoded_bytes.hex()

# Example
schedule = [
    {"mps": 0, "blockDelta": 43200},
    {"mps": 54, "blockDelta": 10894}
]
encoded = encode_supply_schedule(schedule)
print(encoded)  # 0x0000000000a8c00000003600002aa6
```

### Integration with Configuration Flow

When using the configurator skill:

1. **Generate schedule** via `generate_supply_schedule` MCP tool
2. **Encode schedule** via `encode_supply_schedule` MCP tool
3. **Include encoded bytes** in final configuration output
4. **Pass to deployment** script as `auctionStepsData` parameter

The encoded bytes string is what gets passed to the Factory's `initializeDistribution` function as part of the `configData` parameter.

## Getting Current Block Number

Use public RPCs to fetch current block for `startBlock` configuration:

### Available Public RPCs

| Network  | RPC URL                                       |
| -------- | --------------------------------------------- |
| Mainnet  | <https://ethereum-rpc.publicnode.com>         |
| Unichain | <https://unichain-rpc.publicnode.com>         |
| Base     | <https://mainnet.base.org>                    |
| Arbitrum | <https://arb1.arbitrum.io/rpc>                |
| Sepolia  | <https://ethereum-sepolia-rpc.publicnode.com> |

### Fetch Block Number

```bash
curl -X POST "https://mainnet.base.org" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_blockNumber",
    "params": [],
    "id": 1
  }'
```

**Response:**

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x123abc"
}
```

Convert hex to decimal for block number.

## Validation Rules

Before generating configuration, ensure:

1. **Block constraints**: `startBlock < endBlock <= claimBlock`
2. **Valid addresses**: All addresses are valid Ethereum addresses (0x + 40 hex chars)
3. **Non-negative values**: All numeric values >= 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 < 6 decimals
